185.1 | I heard TEN YEARS behind | RAINBO::FLEISCHER | Bob Fleischer | Tue Jun 17 1986 14:40 | 7 |
| A headline-type news item on this morning's Today show said the Janes
report said the US was 10 years behind, and that there was little chance
for the US to catch up before the turn of the century.
(Somehow this is much more believable since the events of the last 6 months.)

185.2 | Ten years at least | LATOUR::DZIEDZIC | | Tue Jun 17 1986 15:58 | 23 |
| I also heard ten years, and I tend to agree. When you consider
the fact the Soviets have had a manned presence in space aboard
their space stations (Salyut and Mir) for the past several years,
you start to wonder where we missed the bus. Considering the
recent setbacks NASA has suffered, combined with the fact their
budget still isn't more than a quarter of the amount the Soviet
Union spends on their space effort, it scares the heck out of me.
I keep hoping the President will commit himself to supporting the
funding necessary to put the space program back on track. We need
an effort like was launched by John F. Kennedy when he started the
race to the moon. (Admittedly mostly politically motivated, but
it sure helped get the bucks when everyone thought the Russians
would have bombs in space before we did!)
The U.S. still has a lead in technology, but we're YEARS behind
in practical experience. Unless a LOT of bucks are forthcoming
in the next few years all those folks who booked rides to the moon
aboard Pan Am will have change their reservations to Aeroflot.
If anyone has any brilliant ideas on how to motivate the politicians
to spend the bucks, PLEASE share them.

185.3 | Space Gap | GALLO::AMARTIN | Alan H. Martin | Tue Jun 17 1986 17:20 | 18 |
| One of the annoying (to me) aspects of the news coverage of this is that
repeated references to the Challenger disaster make it sound like that
was a substantial cause (instead of possibly being a symptom). Even
factoring in a 2 year launch delay, plus resuming operations with 3/4 of
the previous shuttle capacity, plus diversion of a couple of billion for a
new orbiter, it would have been reasonable to judge us as just about as
screwed up before the accident. Having recently chugged this entire file,
I have to wonder whether the "space station by 1990(?)" predictions were
just as bogus as the "24 shuttle launches per year" goal that NASA was
striving for. I say this based on the oft-heard lament of NASA's problems
of too few bucks chasing random short-term goals.
A 59 line AP article relating to this assertion about a 10 year gap
has been entered into note 130.4 in NY1MM::FORUM. And a lot of it is of
questionable conception or expression, even though I agree with many of the
conclusions. But I'm wary of going at it hot and heavy it in *THAT*
conference; the debating team would eat me for breakfast.

185.5 | Who's money are we counting | SKYLAB::FISHER | Burns Fisher 381-1466, ZKO1-1/D42 | Wed Jun 18 1986 12:51 | 9 |
| One thing to remember in all this debate over how much the Soviets
spend vs how much we spend is that NASA is not the only agency spending
money on space. To make a fair comparison, you should probably
add in all the development work done on military boosters/satellites
and SLC 6 at Vandenberg. That, I suspect, would easily double the
figure.

185.6 | The tortoise and the hare | MONSTR::HUGHES | Gary Hughes | Wed Jun 18 1986 18:08 | 40 |
| I don't think another 'moon race' is a good idea. NASA funding dried
up real fast after the initial lunar landing was made.
The US needs good public support of a long term space program rather
than short term extravaganzas. In addition, I beleive that NASA
and the aerospace industry need some form of independant technical
review. Looking back, I think that an enormous amount of money has
been wasted when I look at the variety of launch vehicles, satellite
vehicles and manned spacecraft that the US has developed. Whenever
a new project starts the reaction of the NASA engineers seems to
be to look for new technology to develope in preference to using
existing technology. This leads to systems with overlapping
capabilities (e.g. Saturn 1B and Titan IIIC) being developed. This
needs to be monitored.
The USSR on the other hand seems to prefer slower, evolutionary
development of their hardware. They have used the same basic launch
vehicle (with continued improvements) for all of their manned launches.
As a result, their technology has lagged but their space program
has progressed and surpassed the US program. Areas they have been
lacking (heavy lift launchers, reusable vehicles) will shortly be
addressed with their new medium and heavy lift launchers, the shuttle
and the spaceplane. And continuing with their reuse of technology,
the medium lift launcher doubles as the strapons for the heavy lift
launcher which is also the shuttle launcher.
In retrospect, NASA pushing most of its funding into a completely new
launch system was a bad move. At the time it was at best extremely
risky. Coupled with NASA's continued obstruction of the privatisation
of space by companies wanting to use and market existing launch
vehicles it has crippled the US' launch capability (I think the
Titan and Delta failures were random events that would appear less
disasterous if there had been a steady launch schedule of expendables
in the past couple of years).
The US has the technology NOW (or maybe had) to mount a realistic
space program but, as a country, lacks to will to do so.

185.7 | My 2 cents | 8681::OREILLY | Book'em, DanO!! | Thu Jun 19 1986 15:17 | 27 |
| You also have to remember why the moon race got started. As has been alluded to
in earlier replies, it was to a degree politically motivated. I think Tom Wolff
does an excellent treatment of this subject in The Right Stuff. All B.S. in the
book aside, he hit the nail on the head. The race started in the late 1950's,
when the specter of McCarthyism as still present, and the Soviets were having
success after success while the US had few. Folks like Lyndon Johnson helped
the hysteria, with lines about 'going to sleep under a Red moon'.
It's my firm belief that Vietnam had something to do with the decline of the
space race in the US, in that it was a government-connected operation that spent
huge sums of money for little apparent return (just like the military), not to
mention the fact that we had been in an apparent 'life-or-death' struggle
against the USSR in space (that's what Eisenhower, Kennedy, and Johnson had
portrayed it as). The American people by and large lost their respect (awe?) of
space, and simply grew a) bored and b) complacent with the whole thing. In
fact, the networks even received hundreds of complaining calls about the time
they spent covering the Apollo 13 near-tragedy!
10 years behind? In experience, yes and no - we have a great deal more
experience in deep-space and interplanetary navigation than the USSR does. I'm
not totally convinced that time spent in orbit around the Earth is a good
indicator of anything other than how much time has been spent in orbit around
the Earth. I still think that the overall US technical lead is still strong,
and that the USSR has a way to go. I think I would call the game right now in
favor of the USSR, although only by a couple of years.

| Motivation not withstanding, setting a short term goal by itself
rather than making it part of a longer term program was a mistake.
Changing social values certainly didn't help either but the attitude
of 'well now we've gone to the moon we can forget this space stuff'
was planted from the very outset.
These factors combined (and probably a few others) lead to the doldrums
of the seventies and reduced funding etc.
The Soviets went through similar problems early on. Many of the
Vostok flights and both Voskhod flights were politically motivated.
Things like the first multiple spacecraft flight, the first woman
in space, the multiperson spacecraft were politically motivated
and did not return as much data as they could have. Before anyone
flames at me about the first woman in space, the flight returned
very little biodata as there was not enough time to redesign sensors
etc.
The Soviet program changed dramatically when Kruschev lost power
and changed again just after Apollo 11. The difference being that
it changed direction instead of almost stopping.
I still maintain that setting a short term major goal that is not
part of a long term program will be counter productive.

185.9 | Soviets lag in related areas | GNUVAX::BKETTLER | Brian P. Kettler | Fri Jun 20 1986 09:36 | 28 |

10 years?! Sounds a little high to me....
After all, a space program is very much dependent on computer
technology. All indications are that the Soviets are at least 10
years behind the U.S. in this area. Only within the last few years
has a line of fourth generation computers emerged in the Soviet
Union and these have not entered production yet. Since the space
program is heavily tied with the military in the Soviet Union (at
least probably moreso than in the U.S.), it probably has access
to more high technology than the civilian sector. The soviets have
not had much success with "reverse engineering", i.e. duplicating
(never mind enhancing) western computers and are plagued by bureacratic
squables and lack of quality electronics manufacturing in producing
their own lines of reliable systems.
Granted they could run their space program with big, bulky
(yet reliable) third generation systems but this gap in computer
technology is sure to be a limitation in future, more sophisticated
endeavors. It seems to be much the same story with their launch
vehicles, relying on the proven old technology rather than constantly
going for the latest technology as the U.S. space program does.
Of course using new, untested technology is risky and its development
is time consuming and expensive. Long term benefits, however, can
be gained from this course of action.

| Since relying on the latest in technology has grounded our space
efforts and the Soviets are still running strong. Sincwe we haven't
even begun the battle for funding for a permanent space station
in orbit and the soviets have one operating, since we haven't even
any reasonable short term goals other than the placement of survallance
sattelites (and others). it seem sto me that NASA and the US is
in very bad shape compared to the Soviets. They are capeable of
placing large payloads in space, we are not. They will be in a position
to launch missions to the moon and mars and wherever and we aren't.
I'd say we're way behind. Not that I consider this a "race".
technology is nice but progress is better. If we do not begin to
examine to requirements for mining and exploration on a larger scale
we will not be doing it later. As quality ores become harder to
find this could be the leading edge of trade in the 1990's. The
harder we push into space the more return on the investment we will
get, in terms of spinnoff technology as much as anything else.
Unfortunately many of the same people that criticise the space program
use teflon coated pots and pans, and recieve health care that is
a direct result of the medical research that NASA funded, they just
don't see that.
Quality long range planning is a must for NASA, politics must be
removed from the process and then we will step forward into the
future (again).

| Many people still think the Soviets are behind us especially when it
comes to computers and micro electronics. Maybe they are in the '
manufacturing of such device , but you can buy anything you want off
the self from many different manufactures. I have included a sample
timeline of the MIR space station for an example of how far the Soviets
have come. The MIR space station has over 5 microprocessors on board.
They have a new computer control Soviet space capsule Soyuz called Soyuz-TM.
The Soyuz_TM can dock under 100 percent computer control from a non-palallel
orbit. There deep space activity include trips to Halyey comet , they have
dropped WX balloons on Venus, they have now on the way to MARS a very complicate
satellite that include miniature 'Starwar' type weapons that will be used
to blast pieces of the surface of one of Moons of Mars to find out what
it is made of. By December there MIR space station will have many more
complex modules connected to it. They have the largest group of train
Cosmonauts, the only group with enough space time to go to Mars and
back. They have been quite open with there experiment on the space
station and I am sure we will get a lot of valuable information
form the Soviets the big lag will that of a large group of experience
Astronauts with 100 of hours log in space. Our Astronauts are starting
to retire , as they will be to old for the next shuttle launch, we can
only train a few handful of new Astronauts each year. Yes we are behind

185.13 | ? What did this report REALLY say ? | LYMPH::INGRAHAM | Programmer Bob | Mon Jun 30 1986 14:05 | 47 |
| Could somebody who has access to the report in .0 please expand
on what the report said? Are we supposedly behind in technology
or operations or exactly what?
The reason I'd like to see more of the original report is because
I really take issue with this idea that we're 10 years behind the
Soviets in space technology. I would put us 10-20 years AHEAD,
especially in the types of technology that the Shuttle uses.
Unfortunately when we stretch technology as far as the shuttle did
at the time it was built, we're bound to get bitten on occasion,
and I suggest that we're going through that sort of phase now with
the shuttle. I don't mean to dismiss the current problems we have
-- we're grounded and they're not, but we've got a lot further to
fall before we're behind.
The Soviets don't stretch technology when they build because doing
so requires advanced research which they have always had trouble
doing (although they're getting better and better as they steal
more technology from the west). Their design philosophy is to take
what's on the shelf and use it wherever possible rather than try
to develop something new and risky. They build lower-tech vehicles
which are cheaper, thus they can afford more of them (especially
since their space program is part of their military and is funded
as such) which gives them a greater PRESENCE in space than we have.
Their new shuttle will be just such a combination of throw-away
boosters and ablative shielding -- low-tech and relatively cheap,
but great for PR. Their Proteus (Proton? I forget its name) booster is
a Saturn-V class booster. It hasn't flown yet (at this time), whereas
we flew our last Saturn V for Skylab, OVER 10 years ago.
Do you see the Soviets building payloads like the Hubble Space
Telescope? I submit that they can't. Also, they got a lot of great
PR with the two VEGA's that intercepted Comet Halley. How many
remember that a week before that encounter the Voyager probe (which
has been flying since the 1970's, boys and girls!) sent back the
first pictures from Uranus, performed a gravity-assist flyby, and
headed off to Neptune? It was the third such flyby that spacecraft
had performed, and it required all the precision of a Halley flyby,
but MILLIONS of miles further away.
Now, I don't wish to seem like a hysterical flag-waver here, but
you've got to do some more work to convince me that we're behind
the Soviets in technology. So please somebody expand on the Janes
report so we can see exactly how we're being compared to the Soviets
in this area. If the comparison is in space technology, then I
for one hold the report in utter contempt.

| I don't think anyone is implying we are behind the Soviets in
space technology. I believe the gist of the report was that
we are behind in the development of space, or, if you wish, the
practical use of space.
If the US was to decide today to send a manned mission to Mars,
we would have a TREMENDOUS amount of catch-up time compared to
the Soviets. They easily have an order of magnitude more time
in space than we do, and are working at solving lots of the
problems which such a trip would entail.
Of course, we DID manage to send some chicken eggs into space
on board the shuttle for Colonel Sanders. Now if anyone wants
some Kentucky McNuggets on the way to Mars they'll have to
come to us, won't they!

185.15 | | MONSTR::HUGHES | Gary Hughes | Tue Jul 01 1986 12:58 | 24 |
| I think the point is that the US is behind the Soviets in their use
of space technology, not necessarily the technology itself. Pushing
aerospace technology to its limits and developing an economical
and reliable (and I agree that we have no way of knowing just what
the cost of the Soivet program is) space capability are different
goals and possibly should the responsibility of different agencies.
The Proton launcher is an old vehicle, first used to launch the
Proton satellites, hence the name. Another nomenclature has it a
sthe 'D' series launcher. It is roughly equivalent to the Titan
III family in capabilities.
The Soviet shuttle is not as technologically advanced as the US
shuttle. The more significant points are that the Soviets will also
have a heavy lift capability which they have never had and that
they appear to be using fairly well proven technology. They are
also using common components for their new medium lift launcher,
the heavy lift launcher and the shuttle. That should help control
costs and increase reliability.
The US probably could have used Saturn technology to build something
like this a long ago, if it had wanted to.

| re: .-1 I agree, we are simply behind in usage. The soviet records
held to date are indicative of the soviets "bigger hammer" approach.
They don't tend to rely on new innovation as we do. So they've refined
going in circles to an art form. Big deal. Technologically, we're
way ahead. The soviets have never landed on another body and then
brought a craft back, let alone a manned one. In the Apollo program,
we used computer technology to aim a craft at the atmosphere from
240,000 miles away in such a way that it bounced once and landed
within a mile of an Aircraft carrier. We built the Voyagers, which
are still going strong 11 years later after billions of miles of
space travel. If you want endurance records, try that one. The Soviets
are about to deploy their shuttle, which seems to be somewhat more
expensive to launch than ours (they loose one of the liquid engine
sets) and uses F-1 class engines, which they have very little
experience with.
Someone pointed out that one of their craft uses five onboard micros.
Remember that the 4004 is a microprocessor, as well.
About the only obvious place we're behind is the space platform.
So let's build one.

| Luna 15 and Luna 16 were lunar soil return probes. Luna 15 was a
failed attempt to return a lunar sample before Apollo 11. It was
launched 13 Jul 1969 and remained in lunar orbit for most of the
time Apollo 11 was approaching or near the moon. Two hours before
Eagle left the moon, Luna 15 was commanded out of lunar orbit and
began its descent ending in a crash in the Sea of Crises.
Luna 16 was launched 12 Sep 1970 and landed in the Sea of Fertility
Sep 20. The ascent stage left the moon 26 1/2 hours later and the
return capsule was recovered 24 Sep.
re .16
The other big difference is that the Soviets are actively building
and using their hardware, state of the shelf though it may be. It
would probably take the US the better part of a decade to develope
a heavy lift launcher. That is one 10 year gap.

| re .12
The Soviet probe that will examine the martian moons is due for
launch in 1988.
I am not sure what the full significance of the Soyuz-TM (trademark?)
really is. The Soviets have been using automated docking for sometime,
I thought. In fact, the cosmonauts had very little control over
the early Soyuz vehicles. I suppose ground control could have been
used for these manouvers.
Maybe what this new capability gives them is an automatic docking
system that they trust with a manned spacecraft. There is a lot
of evidence that suggests some of their earlier spacecraft control
systems were not very error tolerant. I recall that they lost a
planetary payload when one of six engines in the core of a Proton
shut down early and they were unable to extend the burn of the other
five, even though they share a common propellant supply. If that
was the state of their Soyuz docking control, I wouldn't have trusted
it.
It may not be a great step, but it is a step.

185.20 | THE TORTOISE AND THE HARE. | EDEN::KLAES | It obstructs my view of Venus! | Wed Jul 02 1986 12:14 | 52 |
| I think the U.S. was foolish to ever have gotten into a "space
race" with the U.S.S.R., primarily because it made us only look
at the short-term goals in space, not the important overall picture
of our very need for space exploration and colonization.
It was our rushing to land men on the Moon that caused us first
to abandon a Shuttle-type manned spacecraft (Dyna-Soar) for the
crudely simple Mercury capsule (Alan Shepard, when asked how he
felt about riding in the Mercury vehicle, answered "How would you
feel if you were flying a ship made by the lowest bidder?!"), then
to build the relatively simple Apollo program, which did not need
(and therefore eliminated) a large manned space station, and did
not continue with the next logical step in lunar exploration - colonies
on the Moon.
The US has always had better technology than the Soviets -
unfortunately political panic caused us to go the fast way in order
to try and beat the Russians, with the results that we are like
the high school athlete who never went to collage, unlike his less
socially active counterpart - the result is a lot of shiny trophies
to show off, but has now fallen behind because he did not continue
further in his education like his counterparts, who may not have
been as "glossy" as the athlete, but are steadily advancing to more
productive goals.
The Soviets too got caught up in this "space race" for a while
and made their own mistakes; but they have not given up, despite
some tremendous accidents (1960-rocket carrying Mars probe explodes
on launch pad, killing @200 technicians, 1967-Soyuz 1 crashes, 1971-
Soyuz 11 crew dies, 1975-Soyuz mission aborted, 1983-Soyuz T-10
has rocket explode underneath ship, which barely escaped.).
Their technology is behind ours in many ways, but they have
finally begun to explore space the way it should have been done
long ago - first with Earth space stations, then with steady
preparations for Moon and Mars bases for future colonization and
mining purposes.
I would like to think that since controlling space IS such a
powerful tool ("He who controls space controls the world."), we
should cooperate instead of behaving on old political motivies by
two leaders from an era of which all are now gone. We should not
keep wallowing in our past mistakes (including the Challenger),
but plan more carefully this time. If all we do is look at the
short term goals of space, human civilization will become as defunct
as the Apollo program. These are not overblown statements - our
resources are not infinite, and neither is Earth's land space -
so planning now to colonize space peacefully is very practical.
America should not be panicking about what the Russians are
doing in space - we should be copying them (NOT racing!) and
cooperating. I do not believe that either country would attack
vehicles and colonies containing crews of both nationalities, neither
are the crews likely to fight when the downfall of one would lead
to the end of the other.

Yes there are corrections, but those are typically to minimize energy

re: .-1 The U.S. really did not enter a "space" race with the soviets
in the 1960s. It was an arms race disguised as a space race to make
it pallatable (SP? where is that *&^ dictionary) to the american
public. We honestly believed that the Russians were way ahead of
us in ICBM technology and would attack at some point. The space
race allowed the investment of billions of dollars in missile and
related technologies without pointing out that we were developing
bombs.

When I sit here in a country which is not truely active in the
"SPACE RACE" it becomes so obvious that the Americans national pride is
placing blinkers over their eyes. The statement that the Americans are
only behind in usuage is oh so true, at the present they really don't
even have a lift vehicle which will reliably deliver payloads to an
Earth orbit. The problem is that while the Americans are trying to
catch up their "usuage" the Russians are developing expertise in space
that will take years if ever to catchup.
Why are the Americans technologically ahead, a better statement is
that they are using equipment which is far more complex and therefore
far more prone to error. This is so obvious with the shuttle where most
launches have had hitches. The last lauch leading to the devastating
explosion but which only appears to be a sympton of inherent errors in the
design. The shuttle appears to be a classic example of over
engineering, it is not suited to any one task and is therefore a half
way solution for all.
Although the Russians are using far simplier equipment they are
able to deliver the results and far more reliabily. They where the
first to place a satelite in orbit, the first to return a craft from
the moon, the first to have a space station and now it appears the
first to have a year round manned space station. In a very short time they
will be the only nation with a vehicle tailored to fit any mission
required, a heavy lifting body for those space station modules and
other large payloads, medium lifting body, a shuttle craft for recovery
of satellites and of course a small shuttle for transfering people to
and from orbit. How long will it be before American catches up to this
sort of flexability. Further to the point so what if the Russian
shuttle costs more to launch, remember the Americans now have to bear
the cost of building a new shuttle or the cost of lost of time in
space, I think the Russian launches really aren't all that expensive.
Yes America has been brillantly succesful in their long range
missions but what is more useful, knowing about Saturn and Neptune or
being able to use that space immediately above us?

PS. I'm hoping the shuttle launches will get going as soon as
possible now that the causes are know.

185.23 | Never say "simpler is better" to an architect | ALIEN::MCCARTHY | | Thu Jul 03 1986 02:37 | 30 |
| If simpler is truly better, why do we sell VAXes instead of PDP-8s?
And why do people buy them?
I would contend that it is NOT complexity which breeds unreliability,
it is the first derivative of complexity, change. NASA as a whole
is VERY conservative about change. So are the soviets. The complex
systems of the shuttle were developed a little at a time by a lot
of people. Remember, it wasn't the 5 way redundant multiprocessing
system that caused the accident, it was a plumbing joint. We couldn't
stick two pieces of steel tube together with a gasket and get it
right. If that ain't simple, I don't know what is.
Yes the soviets were first to launch a satellite. They didn't have
quite enough motivation to make it a warhead on the first launch.
They were also the first to lose an astronaut during service. By
the way, here's a question for debate: Do you think that the soviets
would stop their program for two years if a craft exploded? My guess
is no. Odds are we could launch shuttles from now until the joint
is fixed without another problem. We will not do that, however,
They might. They tend to accelerate their program by taking much
more risk with human life (witness Chernobyl).
I contend we are well ahead technically and somewhat behind in some
uses of space. Unfortunately, the media doesn't understand basic
research and other forms of application of space from the previous
24 shuttle missions. Flagpole sitting on a global scale they
understand, so it makes sense to them that we're behind, and they
spread the rumor.

185.24 | A technology VAXUUM | LATOUR::DZIEDZIC | | Thu Jul 03 1986 10:40 | 45 |
| Don't give that crap about VAXes being better than other machines
because they are more complex! The major reason the VAX architecture
is a DEAD END is because of the incredibly complex instruction set
which does not lead itself well to orders of magnitude increases
in speed which is what is needed. I still maintain my "simple"
DEC-10 using 1970's technology can out-perform any VAX in terms
of raw throughput.
People buy VAXes because they have an extensive amount of software
which will run on almost any machine in the family. If DEC was
to package a RISC machine with VAX software people would buy that
IF THE PACKAGE AS A WHOLE WORKED AS WELL AS IT DOES TODAY.
Your "simple" SRM joint is a good example of the problems involved
in using complex technology. The joint was based on the Titan joint,
which the engineers understood very well. No one who worked on
the SRM joint expected the phenomenon known as "joint rotation".
They predicted the exact opposite. Numerous people interviewed
in the Rogers Commission Report said plainly they didn't know what
went on in the joint.
I would recommend you read the report (it certainly sounds as if
you haven't) before making any other brash statements. I doubt
you would find ANY member of the astronaut corps who would ride
the shuttle with the existing SRM. If you were to plot joint
problems (erosion, primary blow-by, etc.) in the recent past you
would get a curve with a steep upward slope. That joint design
is just an accident waiting to happen. Let's ignore the other
problems with brakes, etc., for now, even though NASA can't before
they can fly shuttle again.
If you use "leading edge" technology, which the shuttle WAS when
it was in the design state, you are bound to encounter problems.
I think the whole point of the Janes report and a lot of the notes
in this file is that we abandoned a perfectly good expendable launch
vehicle program because we thought the shuttle would do everything
better. It clearly can't, and the short-sightedness of the Nixon
administration is to blame for the state we are in now; stuck on
the ground watching the "other guy" fly.
Don't get me wrong, I am an ardent supporter of the shuttle system,
and hope I get a chance to fly on it some day. I just feel it is
much better suited to some tasks than others. Launching satellites
is NOT one of them.

| Re: .21
I must take exception to your claim that the space race was simply a disguised
arms race. You state:
>The space race allowed the investment of billions of dollars in missile and
>related technologies without pointing out that we were developing bombs.
We didn't need the space program to develop "bombs" (I assume you mean
ICBMs). In fact, the space program in the 1960s was the beneficiary of
the missile related research of the 1950s. Blunt body aerodynamics
(re-entry vehicles), ablative heat shielding, inertial guidance, large
liquid rocket engines/launch vehicles, geodetic mapping, and miniaturized
computers were all products of our missile programs. The whole Saturn
launcher and Apollo programs had their roots in the Army Ballistic Missile
Agency at the Redstone Arsenal under Medaris and Von Braun. The Mercury
and Gemini launchers were all modified missiles, as well.
In fact, one can argue quite convincingly that without the ICBM technology
of the pre-space race period, we would have had a much more difficult time
getting men and useful civilian payloads into orbit.
BTW, the first US space program was the 413L system, the original
spy satellite (launched by an Atlas-Able and named Discoverer). This was
started in mid-1954, well before Vanguard or Jupiter-C (Explorer).

| The was an 18 month gap in Soyuz flights after Soyuz-1 (Komarov
died as a result of parachute failure). There was a gap of over
two years after the cosmonauts of Soyuz-11 died.
I don't think there is any evidence to suggest that they would carry
on regardless if they had suffered a manned launch failure.
As for Sputnik vs a warhead... The SS-6 that was used to launch
Sputnik (and formed the basis of the A series launchers) was
operational, i.e. in place with warheads, at the time of Sputnik-1.
It was hardly the first launch of the SS-6.
It is interesting to reflect upon the attitudes that led to the
original 'booster gap'. The Soviets took what they had at the time,
large bulky warheads, rocket technology directly descended from
the wartime A-4, and built a system. The US looked at what it had
at the time and decided to bet on the future with smaller, lighter
warheads promised by the AEC. And to tinker with new ideas along
the way for the Atlas missile. Attitudes haven't changed much in
25 years.

185.27 | Discoverer | MONSTR::HUGHES | Gary Hughes | Thu Jul 03 1986 10:58 | 20 |
| .26 was in reference to .23. I guess a couple of others got in before
me.
Discoverer 1 was launched on a Thor Agena A. What became the Atlas
Able was the USAF's original proposal for the US' first satellite
that was defeated by Vanguard. It eventually launched a couple of
Pioneers, but did not have a good record.
I also do not think you can view the the 'space race' as a blind
for ICBM development. The civilian space program has always tried
to distance itself from the military program, probably too much.
Although nearly all launchers are missile derivatives the space
program was not able to use Atlas or Titan hardware early on for
the fear that it might jeapordize the missile program. The Vanguard
was chosen as the first US launcher because it did NOT contain missile
components and could not be viewed as part of the ICBM program.
The USAF approach was Atlas based and the Army wanted to use a Redstone
based vehicle, the Juno 1, which ultimately launched Explorer 1.

| Say, now we're getting some activity :-)
I didn't mean to imply that those involved in the space race itself
viewed it as an arms race. My point was that the motivation of the
administration (Kennedy's) which started the moon race was less
than altruistic.
My comments re: VAX vs 8 were somewhat misinterpreted. VAXen aren't
only complex from an ISP standpoint. The software has a fair bit
of architecture as well. Users of systems always demand more as
time goes on, and I contend that more function inevitably means
more complexity, or a jump to a completely new technology.

185.30 | Better Spacerace than no Space Program | GWEN::ENGBERG | I'm an Alien! | Mon Jul 07 1986 19:32 | 27 |
| I would also like to see a serious goal-oriented space program instead
of a panicky space race
but...
I have a strong feeling that without the space race, neither USSR
or USA would have gotten off the ground. If US was the only superpower
in the world and the only nation capable of having a space program,
we would not have one. It takes something like national prestige
or fear of being left behind the 'others' to make the politicians
approve those billions of dollars it takes to develop a space
technology from scratch. It's not ideal from a scientific point
of view but it's better than nothing. The world is run by politicians
and accountants whether we like it or not.
Whatever the reason, I'm glad there is a space program. US is
falling behind now but one year from now we'll be out there again.
With a shuttle that is safer than it ever was.
The purpose of the shuttle was to make space flight cheaper and safer,
as such that was a sound idea. I still think it is.
It's true that the shuttle got more expensive than anticipated
but what engineering project of that scale doesn't. Reusable spacecraft
are necessary in the long run and I think the money were indeed
better spent on the shuttle than just on bigger throw-away rockets.

185.31 | RE 185.30 | EDEN::KLAES | Time to make the doughnuts! | Tue Jul 08 1986 19:27 | 10 |
| NASA had originally planned to use a larger shuttle-type rocket
to lift the Space Shuttle into orbit, where the lift vehicle would
return to Earth like the Shuttle, thus the entire launch vehicle
being saved in the process; THAT is a lot cheaper and probably safer
than what is/was being used presently.
The old cliche, "You get what you pay for", has never been more
appropriate.

| re: .24
Your point about the joint is basically an argument that the complexity
isn't the problem, but rather the familiarity of the engineers with
the technology is. Simpler technologies typically have less learning
curve, so the "first timer" mistakes are minimized. No where is
that more evident than in DEC where some engineers change jobs whenever
there's a lull in the conversation. An interesting question is how
to solve that, so that you have engineers who want to stay on a
project long enough to be experts.
-Brian
P. S. Don't take the VAX comments so personally. I happen to like
PDP-11s myself, but VAXes do seem to sell well. Perhaps understanding
why would help unravel the technology questions in this note.
