486.0. "STS-29 ... Discovery" by SHAOLN::DENSMORE (Legion of Decency, Retired) Mon Dec 05 1988 10:34

    There may be a delay in the next Shuttle mission, scheduled for
    February 1989.  Discovery is to fly STS-29 with the major task being
    the deployment of the fourth TDRS (TDRS-D).  A workman apparently
    damaged the nozzle on the IUS for the satellite and NASA officials
    are not sure if and for how long this may delay the launch.  It
    does appear that the delay would be measured in days though.
    
    How about using this note to post news on STS-29?

486.1possible delay to Discovery's rolloutSHAOLN::DENSMOREHoly owned and operated!Thu Dec 22 1988 12:1219
    I heard a report last night that Atlantis was found to have developed
    a crack in one of the main engines.  The report was not clear as
    to whether the crak caused or was caused by the unusual vibrations
    experienced in the launch last month.  (These same vibrations are
    being blamed for the dislodging of material from the ET which damaged
    tiles on Atlantis' underside.)  The report went on to say that
    Discovery would not be rolled out until the problem was understood.
    
    There was apparently some soot in one (both?) of the SRB nozzle
    areas, indicating some escape of hot gases.  In a related report,
    Morton-Thiokol engineers are complaining of insufficient money for
    more testing.  Analysts are saying that these issues need to be
    addressed expeditiously since the shuttle represents our only manned
    access to space for the rest of this century.

    PS. The report mentioned that NASA hoped to fix the extensive tile
    damage on Atlantis in time for its next scheduled launch.

The crack was supposedly something like .005" and was in the ball bearing race
of one of the turbopumps.

    Since Mike Densmore seems to want STS 29 discussions here, I'll
    continue on the IMAX comments.
    
    If IMAX was used in "The Dream Is Alive", then it's not for a spherical
    projection system.  Either that, or the Air & Space museum did
    something so that the same film projects onto a flat screen.  That's
    where I saw "The Dream Is Alive" about a week ago.  Nice, but not the
    effect you get from the spherical projection system.
    
    Anybody know of a place in New England that is showing a 'spherical'
    form of "The Dream Is Alive"?
    
    One thing that struck me in the film was the amount of rocking that was
    evident just prior to liftoff.  The umbilical at the cabin level swung
    away and the whole shuttle rocked several degrees, then took off.  I'll
    bet that adds to a gut-wrenching experience.

486.4STAR::HUGHESWed Jan 04 1989 16:5211
    The same camera is used to produce the raw material for IMAX and
    Omnimax (both tm by Imax, I think). The final printing process is
    different for Omnimax to compensate for the curved screen.
    
    The Boston Museum of Science has an Omnimax theatre, but its not
    currently showing 'Dream'.
    
    Personally, I prefer IMAX as it doesn't have the edge distortion
    that you get in the Omnimax print, but they are both impressive.

486.6bending the stackSHAOLN::DENSMOREHoly owned and operated!Thu Jan 05 1989 07:5114
    re .3
    
    The movement you noticed is "bending the stack" and is caused by
    the ignition and thrust buildup in the main engines which occurs
    during the 6 secs before the solids ignite.  It was this bending
    that contributed to the Challenger accident.  The joints in the
    solids were not designed properly and the cold, stiff rings used
    to seal the field joints couldn't flex and maintain the seal
    properly.  The new joints are better (the cold would still be a
    problem) but when you look at that bend...
    
    Yeah, it must cause one's stomach to flutter!

    re: .3 and .6:
    
    This rocking is popularly called the "twang".  As for cold, new heaters
    are now installed around the field joints to keep the o-rings,
    putty, rabbits feet, and whatever else they're packing into the
    field joints now warm, above 76 degrees F or so.  I hope that
    despite the joint heaters, there are firm launch commit criteria
    specifying no launches in weather below 56 degrees, or whatever
    the magic number is...

    I'm going to be in Florida for a few days soon.  Any word on when
    the roll out for Discovery will take place?  I won't be around for
    the launch but it would still be fun to see it "in person".

486.10STS29 ENTERS the VAB on Jan 18th, so it will be a while after that that it goes to the padDECWIN::FISHERBurns Fisher 381-1466, ZKO3-4/W23Mon Jan 09 1989 14:175
The current schedule calls for Discovery to be rolled TO the VAB from the OPF
on January 18th.  I can't remember how long the SRB/ET mating takes after that.
Surely it must be a week.  If that assumption is true, then the rollout would
not take place till about Jan 25, but I don't have that date for sure.

486.13DelaySHAOLN::DENSMOREHoly owned and operated!Tue Jan 31 1989 08:425
There was a report on CNN this weekend re STS-29.  Two pumps in the main
engines must be replaced.  This will delay the launch by as much as 10 days.
This would put the launch into March.

486.14The domino effectDECWIN::FISHERBurns Fisher 381-1466, ZKO3-4/W23Tue Jan 31 1989 11:3130
    As usual, the media seem to be giving incomplete data.  The problem
    here is the same old thing that was discovered in STS-27:  The bearing
    race in the high-pressure Oxygen pump.  They thought initially that the
    crack found in STS-27 was a one-time problem, but they have not been
    able to verify that to their satisfaction.  The problem pump, as well
    as all the pumps on -29 were made at a new Rocketdyne facility, so
    there is concern that it is a process problem.  Unfortunately, they
    can't inspect more than the #2 (I think) pump without pulling them.
    As of AWST's press date, they had not really decided whether to
    scrub/recycle or not.
    
    The worst thing about all this is that
    
    	1.  The pad must be clear by some date in March in order to prepare
    	    STS-30 for the Galileo launch in April.  Thus, if STS-29 is
    	    delayed too long, it will have to be "cancelled"; presumably
    	    rescheduled some later time.
    
    	2.  The Hubble Space Telescope, currently schedule for launch in
    	    Dec. probably will not be launched until after -29, since HST
    	    makes heavy use of TDRSS.  Currently, there is one good TDRSS
    	    and one sort of marginal one.  -29 is to bring up a third
    	    TDRSS, and it is thought that HST would be only marginally
    	    useful without a full constellation.
    
    Sigh.

STS-29 COUNTDOWN DEMONSTRATION TEST SCHEDULED FOR FEB. 7
  
     One of the significant pre-launch tests, a full dress rehearsal
for the STS-29 launch countdown, is planned next week at Kennedy Space
Center, Fla.  The Terminal Launch Countdown Demonstration Test (TCDT),
involving the STS-29 prime crew, will culminate with a simulated
T-zero at 11 a.m., Tuesday, Feb. 7. 
 
     The five-member flight crew is scheduled to arrive at KSC's
Shuttle Landing Facility on Sunday to participate in the practice
countdown.  The STS-29 crew is comprised of Commander Michael Coats,
Pilot John Blaha and Mission Specialists Robert Springer, James Buchli
and James Bagian. 
 
     While at KSC, the crew will be trained in emergency egress
procedures at Launch Pad 39-B, including a practice drive in the M113
tracked vehicle.  At the pad, they will become familiar with the
location of breathing apparatus, other emergency equipment and the
slidewire basket system. 
 
     Another routine activity for the crew while at KSC is a briefing
by Shuttle engineers.  The briefings, scheduled the day before the
test, are designed to bring the flight crew up to speed on the status
of the vehicle and any unresolved issues. 
 
     Objectives of the test include establishing timelines and
validating sequences involved in the flight crew suit up and entry
into the orbiter's cockpit.  The test also offers an occasion for the
flight crew and the KSC launch team to work together in a launch day
configuration.  Interagency interfaces required to support the
terminal countdown will be evaluated.  In addition, countdown abort
safing steps will be exercised by the launch team. 
 
     The simulated countdown is set to begin at the T-24 hour mark on
Sunday at 8 a.m. EST.  Discovery will be powered-up for the test and
its onboard systems will be activated.  Events in the countdown will
be condensed or simulated to represent activities that occur during
the actual launch countdown and/or to configure the orbiter for the test. 
 
     The countdown will proceed to the T-3 hour mark on Tuesday at 6
a.m. and hold for 2 hours when the flight crew will be awakened and
have breakfast.  Also, the orbiter closeout crew will be assembled and
begin preparing Discovery's cabin for the flight crew's entry. 
 
     After a weather briefing, the flight crew will don their flight
suits and depart for the launch pad.  The closeout crew will assist
the astronauts in getting into the cockpit. 
 
     Ten-minute built-in holds are planned at the T-20 minute and T-9
minute marks.  For the purposes of the test, the countdown will be
halted at about the T-5 second mark at 11 a.m.  The test will be over
once the launch team has performed recycle and safing operations. 
 
     After exiting the cockpit, the flight crew will receive
additional emergency egress training on the 195-foot level of the
Fixed Service Structure.  This is the level on which the orbiter crew
access hatch and the slidewire baskets are located. 
 
     Later that day, the flight crew will return to Houston for final
mission preparations.  They will return to KSC a few days prior to launch. 
 
     Discovery is scheduled to be launched on its eighth mission in
mid-March.  The official launch date will be set at the flight
readiness review held at KSC about 2 weeks prior to the launch. The
primary objective of the five-day mission is to deploy a Tracking and
Data Relay Satellite. 
 
     The TCDT activities will be carried from 6 a.m. until Noon,
Tuesday, Feb. 7, on NASA Select television, RCA Satcom F2R,
transponder 13, 72 degrees west longitude.  Media representatives in
the Washington area can view the activities from the NASA Headquarters
6th floor auditorium, 400 Maryland Ave., S.W.

    THIRD TRACKING AND DATA RELAY SATELLITE TO BE DEPLOYED BY STS-29
  
     Deployment of the third Tracking and Data Relay Satellite 
(TDRS-D) will highlight the 28th Space Shuttle mission (STS-
29).  The assessed launch date is no earlier than March 10, 1989. 
 
     Three TDRS, operating from geosynchronous orbit, are 
required to complete the constellation known as the Tracking and 
Data Relay Satellite System (TDRSS).  TDRSS will increase 
communications, between Earth-orbiting spacecraft and a ground-
based tracking station, from 15 to 85 percent per orbit and 
facilitate a much higher rate of data flow. 
 
     TDRS-C was successfully deployed on STS-26 in September 1988 
and is located in geosynchronous orbit at 171 degrees W. 
longitude, south of Hawaii.  TDRS-D will be located at 41 degrees 
W. longitude, east of Brazil.  TDRS-A, deployed on STS-6 in April 
1983, then will be moved to a parking orbit and used only if a 
failure occurs with one of the remaining two satellites.  TDRS-B 
was lost in the 51-L Challenger accident. 
 
     Commander of the five-man crew is Michael L. Coats, captain, 
USN.  Coats was pilot of STS 41-D, the maiden flight of orbiter 
Discovery.  John E. Blaha, colonel, USAF, is pilot of the 
mission.  STS-29 will be his first space flight. 
 
     Rounding out the crew are three mission specialists:  James 
F. Buchli, colonel, USMC; Robert C. Springer, colonel, USMC; and 
James P. Bagian, M.D.  Buchli is making his third Shuttle flight 
having flown as a mission specialist on STS 51-C, the first 
Department of Defense Shuttle mission, and STS 61-A, the West 
German Spacelab flight.  Springer and Bagian are making their 
first Shuttle flights. 
 
     Discovery, making its eighth flight, is assessed to be ready 
for launch no earlier than 8:11 a.m. EST, March 10, from the 
Kennedy Space Center, Fla., launch pad 39-B, into a 160 nautical 
mile, 28.45 degree orbit.  Nominal mission duration is 5 days, 1 
hour, 7 minutes.  Deorbit is planned on orbit 80, with landing 
scheduled for 9:48 a.m. EST, March 15, at Edwards Air Force Base, 
Calif.  In the event of a slip in the launch, liftoff would occur 
1 minute earlier for each day the launch is delayed. 
 
     TDRS-D will be deployed 6 hours, 13 minutes into the mission 
on flight day 1.  Two additional deployment opportunities are 
available on that day and one the following day.
 
     An Air Force-developed inertial upper stage (IUS) will boost 
the TDRS to geosynchronous orbit (22,300 miles above Earth) after 
deployment from the Shuttle.  The IUS is mated to the TDRS-D and 
the combination spacecraft and upper stage will be spring ejected 
from the payload bay of the orbiter. 
 
     Following deployment, Discovery will maneuver to a safe 
position behind and above the TDRS-D/IUS before the first stage 
of the two-stage IUS motor ignites about an hour after 
deployment.  The three-axis, stabilized upper stage will maneuver 
TDRS to the desired attitude where it will be configured for 
operation by the NASA White Sands Ground Terminal, N.M. 
 
     CONTEL, Atlanta, Ga., owns and operates the TDRSS for 
NASA.  TRW's Defense and Space Systems Group, Redondo Beach, 
Calif., builds the satellites. 
 
     The Orbiter Experiments Program Autonomous Supporting 
Instrumentation System (OASIS) will be flown again on STS-29 to 
record environmental data in the orbiter payload bay during 
flight phases.  OASIS will measure TDRS vibration, strain, 
acoustics and temperature during launch ascent using transducers 
affixed directly to the payload. 
 
     OASIS flight hardware consists of signal conditioning, 
multiplexing and recording equipment mounted on a Shuttle 
adaptive payload carrier behind the TDRS.  Command and status 
interface is achieved through the standard mixed cargo harness 
and the general purpose computers. 
 
     In addition to TDRS-D and OASIS, Discovery will carry the 
Space Station Heat Pipe Advanced Radiator Element (SHARE) in the 
payload bay.  Several secondary payloads will be carried in the 
middeck of Discovery, including the IMAX camera, two student 
experiments, a protein crystal growth experiment and a chromosome 
and plant cell division experiment.
 
     After landing, Discovery will be towed to the NASA Ames-
Dryden Flight Research Facility, hoisted atop the Shuttle Carrier 
Aircraft and ferried back to the Kennedy Space Center to begin 
processing for its next flight scheduled for August.

                    STS-29 MISSION OBJECTIVES
 
     The primary objective of this flight is to successfully 
deploy the Tracking and Data Relay Satellite-D/Inertial Upper 
Stage (TDRS-D/IUS).  TDRS-D is scheduled to be deployed on flight 
day 1, orbit 6.  Several backup deployment opportunities exist 
during the flight.  Secondary objectives are to perform all 
operations necessary to support the requirements of the middeck 
and payload bay experiments. 
 
           LAUNCH PREPARATIONS, COUNTDOWN AND LIFTOFF
 
     After the successful STS-26 mission, Discovery was returned 
to KSC from Dryden Flight Research Facility on Oct. 8.  The next 
day, Discovery was towed to the processing hangar for post-flight 
deconfiguration and inspections.
 
     As planned, the three main engines were removed in October 
and taken to the main engine shop in the Vehicle Assembly 
Building for the replacement of several components.  During post-
flight inspections, technicians discovered a small leak in the 
cooling system of the main combustion chamber of the number one 
main engine.  That engine was shipped back to the vendor where 
repairs could be made and a new engine was shipped from the 
Stennis Space Center, Miss.
 
     Discovery's three main engines were installed before the end 
of last year.  Engine 2031 is installed in the number one 
position, engine 2022 is in the number two position and engine 
2028 is in the number three position.
 
     The right hand orbital maneuvering system pod was removed in 
late October and transferred to the Hypergolic Maintenance 
Facility where a small internal leak was repaired.  One of the 
orbiter's cooling systems, called the flash evaporator system, 
was replaced after some in-flight problems.  Post-flight 
inspections revealed that the system was clogged with foreign 
material.
 
     Once the turn-around activities were completed, Discovery 
was transferred from the Orbiter Processing Facility to the 
Vehicle Assembly Building on Jan. 19.
 
     Solid rocket motor (SRM) segments began arriving at KSC in 
September, and the first segment - the left aft booster - was 
stacked on Mobile Launcher 2 in VAB high bay 1 on Oct. 21.  
Booster stacking operations were completed by early December and 
the external tank was mated to the two boosters on Dec. 16.
 
     The OASIS payload was installed in Discovery's payload bay 
for flight on Dec. 9.  Flight crew members came to KSC to perform 
the Crew Equipment Interface Test on Dec. 11 to become familiar 
with Discovery's crew compartment and equipment associated with 
the mission.
 
     The Tracking and Data Relay Satellite (TDRS-D) arrived at 
the Vertical Processing Facility (VPF) on Nov. 30, and its 
Inertial Upper Stage (IUS) arrived Dec. 27.  The TDRS/IUS were 
joined together on Dec. 29 and all integrated testing was 
performed the first week of January.  As part of those tests, 
Astronauts James Bagian and Robert Springer participated in the 
mission sequence test to verify payload functions that occur 
post-launch and during deployment.
 
     A variety of middeck payloads and experiments, some of which 
are time critical and installed during the launch countdown, are 
processed through various KSC facilities.
 
     Discovery was moved from the OPF to the VAB on Jan. 23, 
where it was mated to the external tank and SRBs.  A Shuttle 
Interface Test was conducted to check the mechanical and 
electrical connections between the various elements of the 
Shuttle vehicle and onboard flight systems.
 
     The assembled Space Shuttle vehicle was rolled out of the 
VAB aboard its mobile launcher platform for the 4.2 mile trip to 
Launch Pad 39-B on Feb. 3.  TDRS-D and its IUS upper stage were 
transferred from the VPF to Launch Pad 39-B on Jan. 17.  The 
payload was installed into Discovery's payload bay on Feb. 6.
 
     A countdown demonstration test, a dress rehearsal for the 
STS-29 flight crew and KSC launch team and a practice countdown 
for the launch, was completed on Feb. 7.
 
     Launch preparations scheduled the last 2 weeks prior to 
launch countdown include change-out of the orbiter SSME liquid 
oxygen pumps; final vehicle ordnance activities, such as power-
on, stray-voltage checks and resistance checks of firing 
circuits; loading the fuel cell storage tanks; pressurizing the 
hypergolic propellant tanks aboard the vehicle; final payload 
closeouts; and a final functional check of the range safety and 
SRB ignition, safe and arm devices.
 
     The launch countdown is scheduled to pick up at the T- 
minus-43-hour mark, leading up to the first Shuttle liftoff for 
the year.  The STS-29 launch will be conducted by a joint 
NASA/industry team from Firing Room 1 in the Launch Control Center.

                    SPACE SHUTTLE ABORT MODES
 
     Space Shuttle launch abort philosophy aims toward safe and 
intact recovery of flight crew, orbiter and payload.  Modes are: 
 
     * Abort-To-Orbit (ATO) -- Partial loss of main engine thrust 
late enough to permit reaching a minimal 105-nm orbit with 
orbital maneuvering system engines. 
 
     * Abort-Once-Around (AOA) -- Earlier main engine shutdown 
with the capability to allow one orbit around before landing at 
Edwards AFB, Calif.; White Sands Space Harbor (Northrup Strip), 
N.M.; or the Shuttle Landing Facility (SLF) at KSC, Fla.
 
     * Trans-Atlantic Abort Landing (TAL) -- Loss of two main 
engines midway through powered flight would force a landing at 
Ben Guerir, Morocco; Moron, Spain; or Banjul, The Gambia. 
 
     * Return-To-Launch-Site (RTLS) -- Early shutdown of one or 
more engines and without enough energy to reach Ben Guerir, would 
result in a pitch around and thrust back toward KSC until within 
gliding distance of the SLF. 
 
     STS-29 contingency landing sites are Edwards AFB, White 
Sands, Kennedy Space Center, Ben Guerir, Moron and Banjul.

               LANDING AND POST-LANDING ACTIVITIES
 
     KSC is responsible for ground operations of the orbiter once 
it has rolled to a stop on the runway at Edwards AFB.  Operations 
include preparing the Shuttle for the return trip to Kennedy.
 
     After landing, the flight crew aboard Discovery begins 
"safing" vehicle systems.  Immediately after wheelstop, specially 
garbed technicians will first determine that any residual 
hazardous vapors are below significant levels for other safing 
operations to proceed.
 
     A mobile white room is moved into place around the crew 
hatch once it is verified that there are no concentrations of 
toxic gases around the forward part of the vehicle.  The crew is 
expected to leave Discovery about 45 to 50 minutes after 
landing.  As the crew exits, technicians enter the orbiter to 
complete the vehicle safing activity.
 
     Once the initial aft safety assessment is made, access 
vehicles are positioned around the rear of the orbiter so that 
lines from the ground purge and cooling vehicles can be connected 
to the umbilical panels on the aft end of Discovery.
 
     Freon line connections are completed and coolant begins 
circulating through the umbilicals to aid in heat rejection and 
protect the orbiter's electronic equipment.  Other lines provide 
cooled, humidified air to the payload bay and other cavities to 
remove any residual fumes and provide a safe environment inside Discovery.
 
     A tractor will be connected to Discovery and the vehicle 
will be towed off the runway at Edwards and positioned inside the 
Mate/Demate Device at the nearby Ames-Dryden Flight Research 
Facility.  After the Shuttle has been jacked and leveled, 
residual fuel cell cryogenics are drained and unused pyrotechnic 
devices are disconnected.
 
     The aerodynamic tail cone is installed over the three main 
engines, and the orbiter is bolted on top of the 747 Shuttle 
Carrier Aircraft for the ferry flight back to Florida.  A 
refueling stop is necessary to complete the journey.
 
     Once back at Kennedy, Discovery will be pulled inside the 
hangar-like facility for post-flight inspections and in-flight 
anomaly troubleshooting.  These operations are conducted in 
parallel with the start of routine systems reverification to 
prepare Discovery for its next mission.
 
            TRACKING AND DATA RELAY SATELLITE SYSTEM
 
     The Tracking and Data Relay Satellite, TDRS-D, is the fourth 
TDRS communications spacecraft to be launched aboard the Space 
Shuttle and completes the constellation of on-orbit satellites 
for NASA's advanced space communications system.  TDRS-1 was 
launched during Challenger's maiden flight in April 1983.  The 
second was lost during the Challenger accident in January 1986.  
TDRS-3 was launched successfully on Sept. 29, 1988, during the 
landmark mission of Discovery, which returned the Space Shuttle 
to flight.
 
     TDRS-1 is in geosynchronous orbit over the Atlantic Ocean, 
just east of Brazil (41 degrees west longitude at the equator).  
When it was launched, it failed to reach its desired orbit 
because of a failure in the upper-stage booster rocket.  A NASA-
industry team subsequently conducted a series of delicate 
spacecraft maneuvers, using on-board thrusters, to place TDRS-1 
into the desired 22,300-mile-altitude orbit.
 
     TDRS-3 is in geosynchronous orbit over the Pacific Ocean, 
south of Hawaii (171 degree west longitude, also over the 
equator).  It has performed flawlessly in tests and helped 
support the STS-27 mission in December 1988.
 
     After its launch, TDRS-D will be designated TDRS-4.  
Following its arrival at geosynchronous orbit and a series of 
tests, it will replace the partially degraded TDRS-1 over the 
Atlantic.  TDRS-1 then will be moved to 79 degrees west 
longitude, above the Equator, where it will be used as an on-
orbit spare.
 
     The two operational TDRS -- those located at 41 and 171 
degrees west longitude -- will support up to 23 user spacecraft 
simultaneously and provide two basic types of service:  a 
multiple-access service that simultaneously relays data from as 
many as 19 low-data-rate user spacecraft; and a single-access 
service that provides two high-data-rate communications relays 
from each satellite.
 
     TDRS-4 will be deployed from the orbiter about 6 hours after 
launch.  The solid-propellant Boeing/U.S. Air Force Inertial 
Upper Stage (IUS) will transfer the satellite to geosynchronous 
orbit.  IUS separation will occur about 13 hours after launch.
 
     The concept of using advanced communications satellites was 
developed in the early 1970s, following studies showing that a 
system of communications satellites operated from a single ground 
terminal could support Space Shuttle and other low-Earth-orbit 
space missions more effectively than a worldwide network of 
ground stations.  The current ground station network can only 
provide support for a small fraction -- typically 15 to 20 
percent -- of the orbits of user spacecraft.  The modern, space-
based TDRS network covers at least 85 percent of the orbits.
 
     The new system also will facilitate a much higher 
information flow rate between the spacecraft and the ground.  
This will be particularly important as NASA resumes regular 
Shuttle flights and launches satellites with high data rates.
 
     NASA's Space Tracking and Data Network ground stations, 
managed by the Goddard Space Flight Center, Greenbelt, Md., will 
be reduced significantly in number.  Three of the network's 
present ground stations -- Madrid, Spain; Canberra, Australia; 
and Goldstone, Calif. -- already have been transferred to the 
Deep Space Network, managed by the Jet Propulsion Laboratory, 
Pasadena, Calif.  The remaining ground stations, except those 
needed for launch operations, will be closed or transferred to 
other agencies.
 
     The White Sands Ground Terminal (WSGT) is situated on a NASA 
test site located between Las Cruces and White Sands, N.M.  A 
colocated NASA facility provides the interface between the WSGT 
and the NASA space network facilities at Goddard Space Flight 
Center.  A technologically advanced second ground terminal is 
being built near White Sands to provide back-up and additional 
capability.
 
     The tracking and data relay satellites are the largest 
privately owned telecommunications spacecraft ever built, and the 
first to handle satellite communications through the S and Ku 
frequency bands.  Each weighs about 2 tons, spans almost 60 feet 
across its solar panels and contains seven antennas.  Each of the 
two gold-plated, single-access antennas measures 16 feet in 
diameter and, when fully deployed, spans more than 42 feet from 
tip to tip.
 
     The combination of satellites and ground facilities is 
referred to as the Tracking and Data Relay Satellite System or 
TDRSS.  NASA leases the TDRSS complement of services from CONTEL, 
Atlanta, Ga., which is the owner, operator and prime 
contractor.  CONTEL's two primary subcontractors are TRW's Space 
and Technology Group, Redondo Beach, Calif., and the Harris 
Corporation's Government Communications Systems Division, 
Melbourne, Fla.  TRW designed and built the spacecraft and 
software for ground terminal operation, and integrated and tested 
the system.  Harris designed and built the ground terminal equipment.
 
     The Space Shuttle, LANDSAT Earth Resources satellites, Solar 
Mesosphere Explorer, Earth Radiation Budget Satellite, Solar 
Maximum Mission satellite and Spacelab have been primary users of 
TDRSS.  They will be joined in the future by the Hubble Space 
Telescope, Gamma Ray Observatory, Upper Atmosphere Research 
Satellite and others.
 
                      INERTIAL UPPER STAGE
 
     The Interial Upper Stage (IUS) will be used to place NASA's 
TDRS-D into geosynchronous orbit during the STS-29 Space Shuttle mission.
 
     The STS-29 crew will deploy the combined IUS/TDRS-D payload 
approximately 6 hours, 13 minutes after liftoff, in a low-Earth 
orbit of 160 nautical miles.  Upper stage airborne support 
equipment, located in the orbiter payload bay, positions the 
combined IUS/TDRS-D into its proper deployment attitude -- an 
angle of 52 degrees -- and ejects it into low-Earth orbit.  
Deployment from the orbiter will be by a spring-ejection system.
 
     Following deployment, the orbiter will move away from the 
IUS/TDRS-D to a safe distance.  The IUS first stage will fire 
about 1 hour after deployment.  After the first stage burn of 146 
seconds, the solid fuel motor will shut down.  After coasting for 
about 5 hours, 13 minutes, the first stage will separate and the 
second stage motor will ignite at 6 hours, 12 minutes after 
deployment to place the spacecraft in its desired orbit.  
Following a 108-second burn, the second stage will shut down as 
the IUS/TDRS-D reaches the predetermined, geosynchronous orbital 
position.
 
     Thirteen hours, 9 minutes after liftoff, the second stage 
will separate from TDRS-D and perform an anti-collision maneuver 
with its onboard reaction control system.
 
     The IUS has a number of features which distinguish it from 
previous upper stages.  It has the first completely redundant 
avionics system developed for an unmanned space vehicle.  It can 
correct in-flight features within milliseconds.
 
     Other advanced features include a carbon composite nozzle 
throat that makes possible the high-temperature, long-duration 
firing of the IUS motors and a redundant computer system.
 
     The IUS is 17 ft. long, 9 ft. in diameter and weighs more 
than 32,500 lb., including 27,400 lb. of solid fuel propellant.  
The IUS consists of an aft skirt, an aft stage containing 21,400 
lb. of solid propellant which generates approximately 42,000 lb. 
of thrust, an interstage, a forward stage containing 6,000 lb. of 
propellant generating 18,000 lb. of thrust, and an equipment 
support section.  The equipment support section contains the 
avionics which provide guidance, navigation, telemetry, command 
and data management, reaction control and electrical power.
 
     The IUS is built by Boeing Aerospace, Seattle, under 
contract to the U.S. Air Force Systems Command.  Marshall Space 
Flight Center, Huntsville, Ala., is NASA's lead center for IUS 
development and program management of NASA-configured IUSs 
procured from the Air Force.
 
                       SECONDARY PAYLOADS
 
SPACE STATION HEAT PIPE ADVANCED RADIATOR ELEMENT (SHARE)
 
     SHARE flight experiment will be mounted on the starboard 
sill of the Orbiter's payload bay with a small instrumentation 
package mounted in the forward payload bay.  The goal of the 
experiment is to test a first-of-its-kind method for a potential 
cooling system of Space Station Freedom. 
 
     The heat pipe method uses no moving parts and works through 
the convection currents of ammonia.  Three electric heaters will 
warm one end of the 51-foot long SHARE.  The heaters turn liquid 
ammonia into vapor which transports the heat through the length 
of the pipe, where a foot-wide aluminum fin radiates it into 
space.  The fin is cooled by the space environment, and the 
ammonia is inturn condensed and recirculated. 
 
     Two small pipes run through the center of the radiator down 
its length, branching out like the tines of a fork at the end 
which receives heat, called the evaporator.  The top pipe holds 
the vaporized ammonia; the bottom holds liquid ammonia.  In the 
evaporator portion, a fine wire mesh wick, which works along the 
same principal as the wick of an oil lamp, pulls the liquid 
ammonia from one pipe to the other, where it vaporizes.  Small 
grooves allow the condensed ammonia to drop back to the bottom pipe. 

     The radiator for SHARE weighs about 135 pounds, but with its 
support pedestals, support beam, heaters and instrumentation 
package, the total experiment weighs about 650 pounds. 
 
     Crew members will switch the heaters on using controls 
located on the aft flight deck.  Each of the experiment's two 
500-watt heaters and single 1,000-watt heater is controlled 
individually and will be switched on in turn, applying heat that 
will increase steadily in 500-watt increments up to a maximum of 
2,000 watts. 
 
     The experiment will be activated for two complete orbits in 
two different attitudes, the first with the payload bay toward 
Earth and the second with the orbiter's tail toward the Sun.  The 
heaters will go through a complete 500-watt to 2,000-watt cycle 
for each activation.  This will simulate the heat that needs to 
be dissipated from the Space Station, and the two attitudes will 
provide data on the heat pipe's operation in different thermal 
environments. 
 
     Other information also may be obtained during STS-29 if time 
permits, including a test of the heat pipe's minimum operating 
temperature, thought to be about minus 20 degrees Fahrenheit, and 
a test of its ability to recover from acceleration.  
 
     The crew may fire the orbiter's aft reaction control system 
thrusters for about 6 seconds, an action that would push the 
fluid in SHARE to one end of the pipe.  The heaters then may be 
turned on again to see if the heat pipe will automatically 
reprime itself and begin operating.
  
CHROMEX
 
     This experiment will determine whether the roots of a plant 
in microgravity will develop similarly to those on Earth.  Root-
free shoots of the plants daylily and haplopappus will be used.  
The experiment will determine whether:  
 
     o The normal rate, frequency and patterning of cell division 
in the root tops can be sustained in space.
 
     o The chromosomes and genetic makeup is maintained during 
and after exposure to space flight conditions.
 
     o Aseptically grown tissue cultured materials will grow and 
differentiate normally in space 
 
     The criteria for comparison include:  number of roots 
formed, length, weight and quality based on subjective appraisal 
as well as quantitative morphological and histological examination. 
 
     Root tip cells will be analyzed for their karyotype, the 
configuration of chromosomes, upon return.  Haplopappus 
dicatolydon is a unique flowering plant with four chromosomes in 
its diploid cells (2n=4).  Daylily monocatolydon also has 
specific features of its karyotype 2n=22. 
 
     Daylily and haplopappus gracilis will be flown in the plant 
growth unit (PGU), located in the orbiter middeck.  The PGU can 
hold up to six plant growth chambers (PGC).  One PGC will be 
replaced with the atmospheric exchange system that will filter 
cabin air before pumping through the remaining PGCs.  The 
experimental plan is to collect and treat roots post flight, 
before the first cell division cycle is completed.  
 
     Previous observations of some plants grown in space have 
indicated a substantially lowered level of cell division in 
primary root tips and a range of chromosomal abnormalities, such 
as breakage and fusion.
  
PROTEIN CRYSTAL GROWTH EXPERIMENT
 
     STS-29 protein crystal growth experiments are expected to 
help advance a technology attracting intense interest from major 
pharmaceutical houses, the biotech industry and agrichemical companies.
 
     A team of industry, university and government research 
investigators will explore the potential advantages of using 
protein crystals grown in space to determine the complex, three-
dimensional structure of specific protein molecules.
 
     Knowing the precise structure of these complex molecules 
provides the key to understanding their biological function and 
could lead to methods of altering or controlling the function in 
ways that may result in new drugs.
 
     It is through sophisticated analysis of a protein in 
crystalized form that scientists are able to construct a model of 
the molecular structure.  The problem is that protein crystals 
grown on Earth are often small and flawed. 
 
     Protein crystal growth experiments flown on four previous 
Space Shuttle missions have already shown promising evidence that 
superior crystals can be obtained in the microgravity environment 
of space flight.
 
     To further develop the scientific and technological 
foundation for protein crystal growth in space, NASA's Office of 
Commercial Programs and the Microgravity Science and Applications 
Division are co-sponsoring the STS-29 experiments being managed 
through the Marshall Space Flight Center.
 
     During the flight, 60 different crystal growth experiments 
will be conducted simultaneously using 19 different proteins.  
The experiment apparatus, first flown aboard Discovery on STS-26, 
fits into one of the Shuttle orbiter's middeck lockers.
 
     Shortly after achieving orbit, a mission specialist 
astronaut will initiate the crystal growing process which will 
continue for several days.  The experiment apparatus differs from 
previous protein crystal payloads in that it provides temperature 
control and automation of some processes.
 
     After Discovery's landing, the experiment hardware and 
protein crystals will be turned over to the investigating team 
for analysis.
 
     Lead investigator for the research team is Dr. Charles E. 
Bugg of the University of Alabama-Birmingham (UAB).  Dr. Bugg is 
director of the Center for Macromolecular Crystallography, a 
NASA-sponsored Center for the Commercial Development of Space 
located at UAB.
 
     Flying crystal growth experiments through their affiliation 
with the UAB Center for Commercial Development of Space are 
Dupont; Eli Lilly & Company; Kodak; Merck Institute for 
Therapuetic Research; Schering-Plough Corp.; Smith, Kline and 
French; Upjohn; and Biocryst Limited.
 
STUDENT EXPERIMENTS
 
Chicken Embryo Development in Space, SE83-9
 
     This experiment, proposed by John C. Vellinger, formerly of 
Jefferson High School, Lafayette, Ind., will determine the 
effects of spaceflight on the development of fertilized chicken 
embryos.  Vellinger is now a senior at Purdue University studying 
mechanical engineering.
 
     The experiment is to fly 32 chicken eggs -- 16 fertilized 
two days prior to launch and the other 16 fertilized 9 days prior 
to launch -- to see if any changes in the developing embryo can 
be attributed to weightlessness.  
 
     All 32 eggs will be placed in an incubator box, designed by 
Vellinger and flown aboard Discovery, while an identical group of 
32 eggs will remain on Earth as a control group.  Throughout the 
mission, Vellinger will attend to the earthbound eggs much as a 
mother hen would, turning them five times a day to counter the 
effects of Earth's gravity on the yolk.
 
     Upon return to Earth, the spaceflight group will be returned 
to Vellinger, who will open and examine 16 of them.  At the same 
time he will open and examine half the control group eggs.  The 
examinations are intended to identify any statistically 
significant differences in cartilage, bone and digit structures, 
muscle system, nervous system, facial structure and internal 
organs.  The other half of the eggs (16 spaceflight and 16 
control) will be hatched at 21 days and their weight, growth rate 
and reproductive rate will be studied.
 
     Vellinger's goal is to determine whether a chicken embryo 
can develop normally in a weightless environment.  The scientific 
team supporting Vellinger includes:  Dr. Cesar Fermin, Tulane 
University; Dr. Patricia Hester, Purdue University; Dr. Michale 
Holick, Boston University; Dr. Ronald Hullinger, Purdue University; 
and Dr. Russell Kerschmann, University of Massachusetts.
 
     Stanley W. Poelstra of Jefferson High School is Vellinger's 
student advisor.  Dr. Lisbeth Kraft, NASA Ames Research Center, 
Mountain View, Calif., is the NASA technical advisor.  Kentucky 
Fried Chicken, Louisville, is sponsoring the experiment.
  
The Effects of Weightlessness on the Healing Bone, SE82-8
 
     This is an experiment proposed by Andrew I. Fras, formerly 
of Binghamton High School, N.Y., to establish whether the 
environmental effects of spaceflight inhibit bone healing.  Fras 
is now attending Brown University's Medical School.
 
     Observations of rats from previous space flights, as well as 
non-weight bearing bone studies in gravity using rats, have shown 
that minerals, calcium in particular, are lost from the body, 
resulting in a condition similar to osteoporosis.  Calcium is the 
main mineral needed in bone formation.  This experiment will fly 
four Long Evans rats where a minutely small piece of bone will be 
removed by a veterinarian from a non-weight bearing bone.  The 
effects of weightlessness on the origin, development and 
differentiation of the osteoblasts (bone cells) and their 
production of callus will be studied.  A matched control group 
will be Earth-based.  
 
     Fras, working with scientists and researchers at Orthopaedic 
Hospital and University of Southern California, will attempt to 
determine whether bone healing in the rat is impeded by the loss 
of calcium and the absence of weight bearing during space flight.  
 
     Andrew Fras is the only student to win the NASA/National 
Science Teachers Association's Space Science Student Involvement 
Program twice.  His first project, "The Effect of Weightlessness 
on the Aging of Brain Cells," flew on STS 51-D in 1985.
 
     Fras' student advisor is Howard I. Fisher of Binghamton High 
School.  Orthopaedic Hospital/University of Southern California, 
Los Angeles, is sponsoring the experiment and providing advice, 
direction and scientific monitoring; the advisors are Dr. June 
Marshall and Dr. Augusto Sarmiento.  Dr. Emily Holton, NASA Ames 
Research Center, Mountain View, Calif., is serving as the NASA 
technical advisor.
  
                              IMAX
 
     The IMAX project is a collaboration between NASA and the 
Smithsonian Institution's National Air and Space Museum to 
document significant space activities using the IMAX film 
medium.  This system, developed by the IMAX Systems Corp., 
Toronto, Canada, uses specially-designed 70mm film cameras and 
projectors to record and display very high definition large-
screen color motion picture images.
 
     IMAX cameras previously have flown on Shuttle missions 41-C, 
41-D and 41-G to document crew operations in the payload bay and 
the orbiter's middeck and flight deck along with spectacular 
views of space and Earth.  Film from those missions form the 
basis for the IMAX production, "The Dream is Alive."  On STS 61-
B, an IMAX camera, mounted in the payload bay, recorded 
extravehicular activities in the EASE/ACCESS space construction 
demonstrations.
 
     The IMAX camera will be used to gather material on the use 
of observations of the Earth from space for a new IMAX film to 
succeed "The Dream is Alive." 
 
          AIR FORCE MAUI OPTICAL SITE CALIBRATION TEST
 
     The Air Force Maui Optical Site (AMOS) tests allow ground-
based electro-optical sensors located on Mt. Haleakala, Maui, 
Hawaii, to collect imagery and signature data of the orbiter 
during cooperative overflights. 
 
     The scientific observations made of the orbiter, while 
performing reaction control system thruster firings, water dumps 
or payload bay light activation, are used to support the 
calibration of the AMOS sensors and the validation of spacecraft 
contamination models.  The AMOS tests have no payload unique 
flight hardware and only require that the orbiter be in 
predefined attitude operations and lighting conditions.
 
     The AMOS facility was developed by Air Force Systems Command 
(AFSC) through its Rome Air Development Center, Griffiss Air 
Force Base, N.Y., and is administered and operated by the AVCO 
Everett Research Laboratory in Maui.  The principal investigator 
for the AMOS tests on the Space Shuttle is from AFSC's Air Force 
Geophysics Laboratory, Hanscom Air Force Base, Mass.  A co-
principal investigator is from AVCO.
 
     Flight planning and mission support activities for the AMOS 
test opportunities are provided by a detachment of AFSC's Space 
Division at Johnson Space Center, Houston.  Flight operations are 
conducted at JSC Mission Control Center in coordination with the 
AMOS facilities located in Hawaii.
  
    ORBITER EXPERIMENTS AUTONOMOUS SUPPORTING INSTRUMENTATION
 
     Special instrumentation to record the environment 
experienced by Discovery during the STS-29 mission is mounted in 
the orbiter payload bay.
 
     Called OASIS, the instrumentation is designed to collect and 
record a variety of environmental measurements during various in-
flight phases of the orbiter.  The primary device is a large tape 
recorder mounted on the aft port side of the orbiter.  The OASIS 
recorder can be commanded from the ground to store information at 
a low, medium or high data rate.  After Discovery's mission is 
over, the tapes will be removed for analysis.
 
     The information will be used to study the effects on the 
orbiter of temperature, pressure, vibration, sound, acceleration, 
stress and strain.  It also will be used to assist in the design 
of future payloads and upper stages.
 
     OASIS is about desk-top size, approximately 4 feet in 
length, 1 foot in width, 3 feet in depth and weighs 230 pounds.
 
     The OASIS data is collected from 101 sensors mounted along 
the sills on either side of the payload bay, on the airborne 
support equipment of the Inertial IUS and on the tape recorder 
itself.  These sensors are connected to accelerometers, strain 
gauges, microphones, pressure gauges and various thermal devices 
on the orbiter.
 
     OASIS was launched aboard Discovery on STS-26 in September 
1988.  Upon return to KSC, the OASIS recorder was removed from 
the payload bay and the tape analyzed.  Use of this data improved 
efficiency in turnaround of the IUS airborne support equipment 
for Discovery's STS-29 mission.  As more OASIS data is collected, 
it will be increasingly beneficial for future IUS flights on the 
Space Shuttle.
 
     On STS-29 launch day, the system will be turned on 9 minutes 
before Discovery's liftoff to begin recording at high speed to 
recover high fidelity data.  Following the first burn of the 
orbital maneuvering system, the recorder will be switched to the 
low data rate and will be commanded again to high speed for 
subsequent OMS burns.
 
     Different data rates are to be commanded from the ground at 
various times during the on-orbit operations.  If tape remains, 
the recorder will operate during descent.
 
     NASA is flying OASIS aboard Discovery in support of the IUS 
program office of the Air Force Space Division.  The system was 
developed by Lockheed Engineering and Management Services Company 
under a NASA contract.  Development was sponsored by the Air 
Force Space Division.

              SPACEFLIGHT TRACKING AND DATA NETWORK
  
     Although primary communications for most activities on STS-
29 will be conducted through the orbiting Tracking and Data Relay 
Satellites (TDRS-1 and TDRS-3), NASA Spaceflight Tracking and 
Data Relay Network (STDN)-controlled ground stations will play a 
key role in several mission activities.  In addition, the 
stations, along with the NASA Communications Network (NASCOM), at 
Goddard Space Flight Center, Greenbelt, Md., will serve as 
backups for communications with Space Shuttle Discovery should a 
problem develop in the satellite communications.
 
     Three of the 14 stations serve as the primary communications 
focal point during the launch and ascent phase of the Shuttle 
launch from Kennedy Space Center, Fla.  They are Merritt Island 
and Ponce de Leon in Florida and Bermuda downrange from the 
launch site.  For the first minute and 20 seconds, all voice, 
telemetry and other communications from the Shuttle are relayed 
to the mission managers at Kennedy and at Johnson Space Center, 
Houston, by way of the Merritt Island facility.
 
     At 1 minute, 20 seconds, the communications are picked up 
from the Shuttle and relayed to KSC and JSC from the Ponce de 
Leon facility, 30 miles north of the launch pad.  This facility 
provides the communications for 70 seconds, or during a critical 
period when exhaust energy from the solid rocket motors "blocks 
out" the Merritt Island antennas.
 
     The Merritt Island facility resumes communications to and 
from the Shuttle after those 70 seconds and maintains them until 
6 minutes, 30 seconds after launch when communications are 
"switched over" to Bermuda.  Bermuda then provides the 
communications until 8 minutes, 45 seconds after liftoff when the 
TDRS-1 (East) satellite acquires the Shuttle.
 
     Another critical point in the mission is deployment of TDRS-
D from the orbiter.  Ground stations at Canberra, Australia; 
Goldstone, Calif.; Hawaii; and Guam provide the communications 
for the crucial time the satellite is being transferred to 
geosynchronous orbit, 22,300 miles above Earth.
 
     Another time the ground stations will play a key role is 
during the landing.  The facilities at the Ames-Dryden Flight 
Research Facility and the Goldstone Deep Space Network stations 
provide primary communications for the Shuttle during its 
approach and landing at nearby Edwards Air Force Base.
 
     More than 1,500 persons will maintain the stations on a 24-
hour basis during the 5-day mission.  In addition to the 14 
ground stations, there are six major computing interfaces located 
at the Network Control Center and the Flight Dynamics Facility, 
both at Goddard; Western Space and Missile Center, Vandenberg 
AFB, Calif.; Air Force Satellite Control Facility, Colorado 
Springs; White Sands Missile Range, N.M.; and the Eastern Space 
and Missile Center, Fla.
 
     The Merritt Island station provides the data to KSC and JSC 
during pre-launch testing and the terminal countdown.  In 
addition to Merritt Island, Ponce de Leon and Bermuda, which 
provide S-band communications during launch and ascent, C-band 
facilities at Bermuda; Antigua; Cape Canaveral Air Force Station 
and Patrick Air Force Base, both in Florida; and Wallops Flight 
Facility, Va., provide tracking data, both high and low speed, to 
KSC and JSC.
 
     S-band systems carry radio frequency transmissions of 
command and telemetry.  C-band stations provide radar (skin) 
tracking for orbit determination.  Ultra high frequency 
air/ground (UHF A/G) stations provide astronaut voice 
communications with the ground.
 
     NASA plans to close some of its stations as the satellite 
tracking system becomes more operational.  Stations at Santiago, 
Chile, and Guam are expected to cease operations on June 30, and 
Hawaii and Ascension will stop operations Sept. 30, 1989.  
     Currently, Yarragadee, Australia, is part of NASA's laser 
network and will be available for use in an emergency during NASA 
missions as a backup to TDRS-West (TDRS-3).
 
     Closing of the stations is expected to provide savings of 
approximately $30 million a year.
 
                MCC REAL TIME DATA SYSTEM (RTDS)
 
     The real time data system is an intelligent, real-time 
assistant to the flight controllers in the Mission Control 
Center, Johnson Space Center, during a Shuttle mission.  Flight 
controller expertise is represented in the form of algorithms and 
expert systems.  The expert systems monitor performance of 
various Shuttle systems.  RTDS runs on MASSCOMP mini-computers 
which have multiple processors.
 
     During a mission, the expert systems process Shuttle 
downlink data and display the results to flight controllers.  
Information is presented to the flight controllers through 
familiar graphs and schematics, indicating anomalies through 
color highlights, text messages and tones.  RTDS is significant 
because much of the monitoring work traditionally done by the 
flight controller and other staff can now be off-loaded to the 
expert system, leaving the flight controller free to perform 
other tasks.
 
     RTDS was used during STS-26 to aid flight controllers in 
monitoring Shuttle main engine performance during the critical 
ascent phase and the deployment of the Tracking and Data Relay 
Satellite.  Based on the success of RTDS during the STS-26 
mission, the system has been expanded and incorporated into other 
Shuttle flight control disciplines.
 
     During STS-29, RTDS will be used to aid the integrated 
communications officer, booster, mechanical, manipulator and crew 
systems flight controllers.  RTDS displays have been installed 
into and around the consoles of these three flight control 
disciplines, providing the information to perform certain flight 
control tasks.  Additionally, the electronic analog of certain 
cockpit instruments, such as the attitude and direction 
indicator, are being modeled on the RTDS displays to give flight 
control personnel an understanding of the information available 
to the astronauts flying in the Shuttle.
 
     RTDS represents the first operational use of real-time 
expert system technologies for manned spacecraft monitoring and 
as such, has provided a hands-on understanding of these 
technologies.  The system will be expanded on future flights to 
include additional controller functions.
 
                        CREW BIOGRAPHIES
 
     MICHAEL L. COATS, 43, captain, USN, is mission commander.  
Born in Sacramento, Calif., he considers Riverside, Calif., his 
hometown.  Coats is a member of the astronaut class of 1978. 
 
     Coats was pilot of the 14th Space Shuttle mission (41- D) 
launched Aug. 30, 1984 marking orbiter Discovery's maiden 
flight.  The 41-D crew earned the nickname "Icebusters" because 
of their successful removal of hazardous ice particles from the 
orbiter using the remote manipulator system.  The flight included 
several "firsts:"  The first time three communications satellites 
were deployed during one mission; the first "frisbee" satellite 
deployment; and the first time a commercial payload specialist 
flew aboard the Shuttle. 
 
     Coats has logged more than 144 hours in space.  He earned a

486.18Busy Month...SHAOLN::DENSMOREHoly owned and operated!Wed Mar 01 1989 07:3711
I have read some accounts that say STS-29 could be ready to go on the 9th
but it is now bumping up against a DoD launch (Trident test or Delta?)
that is scheduled for the 10th.  The Air Force cannot handle two launches
so close together and the Shuttle will be bumped until the other launch
has occurred.  It appears that the 12th is a likely candidate for the
"early" date.  That gives STS-29 about a one week window before it must
clear the pad one way or another in order to make way for STS-30.   STS-30
is carrying the Magellan Venus probe and has to fly in April or wait a
considerable amount of time for another favorable launch window.

RELEASE:  89-25
 
    SHUTTLE TILE DAMAGE STUDY COMPLETED; "GO" FOR DISCOVERY FLIGHT 
  
     A NASA review panel, investigating the damage to the orbiter
Atlantis' thermal protection system during the STS-27 mission, found
that the most probable cause was ablative insulating material from the
righthand solid rocket booster nose cap dislodging and striking the
orbiter about 85 seconds into flight. 
 
     The Shuttle was traveling at approximately two and one-half times
the speed of sound.  At that speed, tests and analyses have
demonstrated that material breaking away from forward portions of the
vehicle can result in debris striking the orbiter with enough force to
damage the tiles. 
 
     Following its landing on Dec. 6, 1988, inspection revealed that
Atlantis had sustained slightly more than 700 individual tile impacts.
The damage was concentrated on the lower surface tiles of the
righthand side.  One complete tile was found missing from the damaged
area below the crew compartment, and an insulation panel was missing
from the right orbital maneuvering system (OMS) pod. 
 
     In its effort to understand how the damage occurred, the review
team gathered extensive physical evidence by examining the Atlantis
vehicle, reviewing prelaunch inspection records and procedures,
assessing tracking camera footage and interviewing Atlantis' flight
crew.  They studied the flight hardware design and build records and
conducted laboratory tests on the damaged tiles, looking for bits of
the damaging debris material. 
 
     In addition to such tests and analyses, the finding concerning
the most probable cause was based on: 
 
     o  A determination that several manufacturing process variables on 
the right booster nose cap were very near their specification limits; and, 
 
     o  The discovery of minute bits of the booster nose cap
insulation material and paint embedded in the damaged tiles and OMS
pod blankets. 
 
     The review team also reported that debris from other sources,
including repaired external tank insulation and cork material covering
the solid rocket motor joints, may have caused minor tile damage. 
 
     The team's findings do not pose any constraint for launching
Discovery on the STS-29 mission, according to the report.  A major
reason for concluding that the STS-29 hardware is ready to fly stems
from an improvement made to the suspect insulating material covering
the booster nose caps. 
 
     The suspect material, known as Marshall Sprayable Ablator (MSA),
was used in its original formulation for nose caps up to and including
the STS-27 mission.  Following fabrication of the STS-27 nose caps,
changes were made in the material's properties, manufacturing process
and application.  The result was an improved product designated MSA-2.
The changes have been shown to produce stronger bonds between the
insulating material and the surface on which it is applied. 
 
     The first boosters to be fabricated with the improved material
are those for the upcoming STS-29 flight.  This new material recently
was subjected to additional strength tests, called "pull tests," and
successful completion of those tests has further bolstered confidence
that the material will perform successfully. 
 
     Despite the team's belief that the change in nose cap insulation
material will prevent severe tile damage in the future, the report
recommended several other steps toward further understanding and to
minimize minor damaging debris on future flights.  The recommended
steps include: 
 
     o  Expanding an existing operations team to monitor and report on
this critical area for all future flights; 
 
     o  Selectively performing the pull tests on SRB nose cap
insulation material prior to future flights; 
 
     o  Inspecting the joint cork material which externally covers solid 
rocket motor field joints to make sure there are no low density inclusions 
in the material (such inclusions, if found, normally are repairable); 
 
     o  Reviewing design criteria and searching for process
enhancements to further minimize debris potential; and, 
 
     o  Assigning more data-gathering sources, such as additional
cameras, for future flights.  If and when tile damage does occur, such
additional sources would yield more data and other evidence, thus
providing a better basis for establishing the causes. 
 
     The review panel was chaired by John W. Thomas of Marshall Space
Flight Center.  Other members include Jay Honeycutt of the NSTS
Program Office, NASA Headquarters (alternate chairman); Jack Nichols,
James Earle, James Hester, Keith Henson and Dewey Channell of the
Marshall Space Flight Center; Marion Coody, Robert White, Gary Coen
and Don McMonagle of the Johnson Space Center; and Charles Stevenson
and Judith Kersey of the Kennedy Space Center.

The launch of STS-29 will be delayed from Saturday, 11-Mar, until
Monday, 13-Mar, at the earliest.  The delay is caused by the need
to repair/replace an electrical subsystem related to ET separation.

    Space Shuttle Discovery is ready once again to take to the skies,
as well as outer space.  The five person astronaut team is scheduled
to ride Discovery into Earth Orbit on Monday, March 13. 
 
    The shuttle crew will test hardware that will help America build
Space Station Freedom in the 1990's and deploy a 19 ton communications
relay satellite.  The astronauts will also conduct a wide range of
experiments, from charting environmental hazards around the globe to
growing protein crystals in microgravity that could lead to cures for
certain medical diseases.  As the third shuttle flight since the loss
of Challenger and its crew, the mission will further qualify space
shuttle vehicles for safe and reliable human transportation into space. 
 
    Dial-A-Shuttle based at Johnson Space Center in Houston will be
providing round-the-clock coverage during this exciting five day
mission.  You'll be able to listen to the astronauts talking live to
Mission Control.  When live coverage is not available, you'll hear our
informed reports and news updates, including background information on
the mission from space experts.

YUP!  C-PAN II provided excellent (via NASA) coverage.  Everything was quoted as
being nominal.  Camera coverage was excellent - SRB sep was visually clean, 
visual tracking continued up to abort-to-orbit!

At 12 minutes into the flight, I hit the road.  The ET had seperated cleanly,
they had not needed the OMS-1 burn and no system anomolies had been reported.

    They're still looking good.  TDRS is scheduled to be deployed in about
    5.5 hours.  I have the VCR set...

    Was anyone else dissapointed by CNN's coverage?  When the countdown
    resumed at T-9 minutes, ABC, NBC, and CBS broke into their regular
    schedules and went immediately to the cape.  CNN continued showing this
    innane fitness show and then launched into 2 minutes of commercials.
    
    When they finally got back at T-3 minutes, Tim Mintire and Bonny Dunbar
    bored us through another 2.5 minutes.  At T-30 sec. they finally cut to
    the NASA feed, but put this annoying "Live from Kennedy Space Center --
    CNN" across the bottom 1/5th of the screen.  They didn't even stay with
    the launch until the shuttle dissappeared from sight.  They had to cut
    to their commentator on the ground saying how he could still hear the
    engines, and boy, wasn't that fun?  ABC, CBS, and NBC were still
    following the launch up until MECO.  CNN had long since gone to
    commercial...  With coverage like this, it won't take long to turn off
    the American public.

    CNN usually provides excellent coverage of shuttle launches but after
    today's, I think I'm going to watch the next one on one of the other
    networks.

    ...still not sorry that I stayed home to watch it though.  It sure is
    an awesome sight to behold!

    One other interesting note: at one point CNN cut to a shot of the press
    section packing up to go home.  The shuttle Atlantis was clearly
    visible in the background on its way to, or already at the pad.

      Sorry to say that on this mission the orbital inclination is not
    high enough for the shuttle to be seen from New England.  In fact,
    I don't believe that it can be seen by anyone living north of Atlanta.
    The last DOD mission's orbit covered New England.

        Here is what information I could get from USENET's sci.space 
    newsgroup on STS-29's orbital statistics.

        As for the DISCOVERY itself, the loss of pressure in one of 
    the three hydrogen tanks which assists in powering the Shuttle is 
    being studied as to whether or not it is serious enough to end the 
    mission a day early.  The astronauts have launched the TDRS.

    Discovery launched at 14:57 UTC March 13, as most of you know by now;

    Space Shuttle Discovery will be visible Friday morning, 17 March,
as it tracks across mid-Florida on the fifth day of its mission.  At
05:59:45 a.m., plus or minus a few minutes, Discovery may be seen to
be moving right to left in the sky due south, reaching a maximum
elevation of only 13 degrees.  As such, it will be difficult to
distinguish from an airplane, although binoculars should show the
distinction (the space shuttle will appear as a single point -- an
airplane would show separate lights).  It will appear about as bright
as most bright stars in the sky. 
 
    Further south in the state, Discovery will track much higher in the sky.

silly and hope they drop it after this flight.  The Capt. Kirk bit WAS
pretty clever though.

The CNN coverage last night indicated that the boosters were recovered
in great shape.  So far, so good.  Won't feel all that comfortable though
until they replace them with a new design...

486.34Just what did "Kirk" say?VIRRUS::DIEWALDWindows and murders and orcs, oh my!Fri Mar 17 1989 17:053
I just caught the end of the CNN report talking about what Shatner did.
What did he say to the crew?

    	William Shatner/Kirk basically said that he was now in temporary
    command of the Space Shuttle DISCOVERY, and that the mission was
    proceeding well and the crew was fine.
    
    	You know, the usual log entry.

/* ---------- "NSS Hotline Update for 3/17/89" ---------- */

    This is the National Space Society's Space Hotline for the week ending 
March 17, 1989. 
 
    With the closing of the STS-29 mission, the crew of the Space
Shuttle Discovery are ending their mission by stowing gear and
wrapping up experiments.  The landing is scheduled for 9:32am EST
Saturday morning at Edwards Air Force Base in Calif.  A turnout of
20,000 spectators is expected to watch Discovery land. 
 
    Friday morning President Bush called the crew to congratulate them
on a successful mission which was the first of his new administration.
In the conversation he stated that the space program, especially the
space station is an investment in our future.  He went on to say that
even though we are living through difficult budgetary times he is
determined to go forward with a strong, active space program. 
 
    The mission so far has been one of qualified success. Successes
included the deployment of $100 million Tracking Data Relay Satellite,
protein crystal growth experiments, and various other life sciences
experiments. Problems arose as the false readings in the hydrogen
storage tank number 3, a broken IMAX movie camera belt, and the fluid
ammonia heat exchange experiment. All remedied eventually, but they
did cause headaches for the crew. 
 
    The first generation heat exchange system designed to be used on
the space station did not work as planned due to air bubbles that kept
the ammonia fluid from radiating heat into space.  Firing the motors
of Discovery did not free the air bubbles in the 50 foot pipe, so the
crew will flush the pipe and give it one more try prior to landing. 
Using the IMAX camera the crew filmed environmentally sensitive areas
of the earth including a huge smoke cloud over the Amazon, and the
Sahara Desert. 
 
    Meanwhile back at Kennedy Space Center..... 

    NASA officials stated that preparations for the launch of the
Space Shuttle Atlantis and its Magellan Venus Radar Mapping probe are
right on the mark for launch on April 28, 1989.  The launch is time
critical since the window for the Magellan spacecraft lasts only until
May 25.  The Magellan Radar Mapper will map about 90% of the planet's 
surface after making its 26 million mile journey to the cloudy planet.

    In the post-landing briefing at Edwards I heard an estimate of 450,000
    spectators.  The fact that the landing was on a weekend may have
    helped.

    Someone a few notes back talked about the launch being on CPAN-II or 
    something like that?  Is that C-Span?   Or something other than NASA
    Select that is on regular Cable TV?

                      MISSION CONTROL STATUS REPORT #4
                               FLIGHT DAY TWO
  
    6:15 am CST -- Tuesday, March 14, 1989
  
The crew of Space Shuttle mission STS-29 aboard Discovery was 
awakened by the voice of James Brown singing his hit "I Feel 
Good" at 2:57 am central standard time this morning.
 
Following wakeup, exercise and breakfast, the crew was scheduled 
to conduct several of the detailed supplementary objectives 
planned for the flight, including salivary tylenol kinetics, 
central venous pressure and cerebral blood flow kinetics.  They 
also demonstrated the new text and graphics system or TAGS used 
to uplink data to the crew.
 
Preparations also began for other activities for the day which 
will include activation of the Space Station Heatpipe Advanced 
Radiator Element or SHARE and continued monitoring of the CHROMEX 
plant cell division experiment and the student experiment 
involving chicken embryo development.
 
Several Earth observation photo opportunities will be available 
to the crew today including Lake Chad, Niger River delta 
deforestation, Angola coastal region, Big Bend National Park 
fires and the effects of the recent heavy rain activity on the 
Peruvian coast.  Due to increased solar flare activity, the crew 
will also have the opportunity to photograph the Aurora Borealis 
which is visible over the western United States.
 
Following launch yesterday morning, the crew deployed the 
Tracking and Data Relay Satellite, which is now in its final 
orbit at about 22,300 miles above the Earth.  The satellite has 
also deployed its solar arrays and both antennas.
 
Flight controllers are continuing to work one system anomaly 
observed during system checks after launch.  Seen was unusual 
manifold pressure fluctuation in cryogenic hydrogen tank number 
three which is associated with erratic heater operations.  Work 
to understand the phenomenon continues in Mission Control.
 
The next mission status report will be at approximately
10 am CST.
  
                    MISSION STATUS REPORT #8
                       FLIGHT DAY THREE
  
    5:45 am CST -- Wednesday, March 15, 1989
  
The "Marine Corps Hymn" awoke the crew of Discovery early this 
morning, a tribute to mission specialists Bob Springer and Jim 
Buchli, both colonels in the U.S. Marine Corps.  Coincidentally, 
that wakeup music selection was made by then-Capsule Communicator 
Ken Cameron who is a lieutenant colonel in the Marine Corps.
 
Overnight, flight controllers made adjustments to the crew flight 
plan and uplinked those changes prior to crew wakeup.  Following 
exercise and breakfast, the crew will settle into the days 
activities which will include continued Earth observation 
photography using the IMAX camera, and monitoring of the CHROMEX 
plant cell division, chicken embryo and Space Station Heatpipe
Advanced Radiator Element experiments.
 
During checks of CHROMEX yesterday, the controlled temperature of 
the experiment began to rise.  The crew is currently working 
uplinked procedures to take temperature readings on the inside 
and outside of CHROMEX.
 
The SHARE experiment was shutdown about two hours into the 
operation when the electric heaters evaporated the ammonia faster 
than it could recirculate, drying a portion of the liquid passage 
in the evaporator section.  SHARE will be reactivated later this 
morning when the liquid ammonia builds up again in the evaporator 
section.
 
During IMAX camera operation yesterday, the belt on the drive 
mechanism came off track causing a loss of about 200 feet of 
film.  The crew replaced the belt and normal camera operations 
continued.
 
Work on the anomalous cryogenic hydrogen tank number three 
pressure and manifold pressure signatures continues.  Once given 
the call from Mission Control, the crew will attempt the run 
single heater operations and analyze the results prior to going 
to final configuration.
 
As of 5:30 am CST, Discovery was approaching the west coast of 
Australia on orbit 30. Cabin temperature was 75 degrees and 
humidity 35 percent as the vehicle circled the Earth at a 177 by 
162 nautical mile altitude.
 
The next status report will be at about 9:30 am CST.
  
                      MISSION STATUS REPORT  #12
                           FLIGHT DAY FOUR
  
    Thursday, March 16, 1989 -- 6 am CST
  
In a reversal of traditional procedure, the crew of Discovery 
this morning "awoke" Mission Control with the theme song from the 
popular television show "Star Trek" followed by congratulatory 
comments from actor William Shatner who played Captain Kirk on 
the show.  Flight controllers followed Discovery's message by 
uplinking the fight songs from each crew members' college.
 
Another busy day is planned aboard Discovery including 
troubleshooting of the Space Station Heatpipe Advanced Radiator 
Element and continued monitoring of the chicken embryo and 
CHROMEX experiments and filming with the IMAX camera.
 
Yesterday, work associated with an abnormal cryogenic hydrogen 
tank reading culminated when the Discovery crew was given the 
"go" to turn on one of two heaters in tank number three.  The 
system has been operating normally since activation of heater B 
in the tank.
 
During SHARE activities yesterday the crew conducted a second run 
which was terminated 28 minutes into the experiment due to the 
drying out of liquid ammonia in the evaporator section of the 
heat pipe.  The crew again powered up SHARE at 5:47 am CST today 
with results to be determined.
 
The next mission status will be at 9:30 am CST.
