448.0. "Space Goals: US vs USSR" by SOFBAS::WOLFF (Greg Wolff, CPDW::, 273-5738) Wed Aug 10 1988 11:07

    I would like to discuss what I believe is wrong with the US space
    program in light of the successes of the USSR space program.

    In a nut shell:  The Soviets appear to have a very clear goal toward
    which they are moving.  We appear to have no goal other than to do
    something that's "better" or "flashier" or "higher tech" than anybody
    else.

    The US has built the STS.  It was built out of all new technology, very
    complex, a technological marvel.  It can take very sofisticated
    platforms into orbit to perform short term experiments.  It can take
    experimental platforms into orbit (Hubble Telescope etc).  It is a
    purely scientific (or military) platform, it CAN NOT provide cost
    effective access to orbit.  Nor can it provide the neccessary access to
    orbit for a sustained presence in orbit or the deployment of a
    comprehensive deep space exploration program.

    The Soviets have two primary goals:  1) Permanent Soviet Manned space
    platforms, and 2) a comprehensive deep space exploration program.
	To achieve these goals the Soviets have developed a heavy lift
    vehicle to lift the massive sections of their platforms.  To lift the
    people into orbit they are developing a small personnel transport
    shuttle.  They have also continued to develop intermediate size booster
    systems to be used in the deployment of their deep space probes.  The
    boost hardware that the Soviets have developed fits the goals that they
    have stated they are seeking to achieve.  (Please read note 446.31)

    On the other hand, the US has stated that the goals of the USSR are the
    goals of the US (ie build a permanent manned presence in space and
    explore space).  But the US has developed a boost hardware system which
    is NOT consistant with those goals.  We have built an STS which is a
    show case IN AND OF ITSELF.  It is its own reason for existence, not
    what it does, but the fact that it is the best and brightest and most
    complex, and "Wow, look at us, we can build a better machine for
    scientific research than anybody else".

    I submit that we have the cart before the horse, and that the Soviet
    space program is (possibly) a decade ahead of ours.  There efforts will
    endure while the STS fade away.

    Some observations on differences between NASA and the Soviet space
    program.
    
    1) NASA and its Soviet equivalent have to operate within very different
    systems.
    
    NASA has to 'sell' its programs to the legislature who in turn have
    to beleive it will help them get re-elected (well, at least 50%
    of the time). Bottom line is that they have to sell the programs
    to the public.
    
    This means that the big, flashy programs get funded, at least
    initially. The public's attention span is quite short (politicians even
    more so) so once the 'big, flashy' programs become just 'big', they get
    jerked around a lot. 
    
    The Soviet system does not have to sell the idea to the public,
    although I get the impression that the level of public interest is
    higher (could be completely wrong about the latter). They do presumably
    have to sell their programs to their politicians. The main difference
    here is that their politicians tend to stay in power longer, so the
    space folks can spend less time selling and more time doing. 
    
    Remember that there have been long periods of routine
    one-step-at-a-time missions in the Soviet program that got very
    little coverage in the West. Lately, they seem to have become better
    at publicising their programs (or perhaps now they are allowed to).
    
    2) NASA needs leaders, but all they get is managers. From leadership
    comes goals, which they don't really have. No idea about the Soviets
    here, although Sagadev (sp?) might be such a leader. Interestingly, he
    intends to resign his post, apparently voluntarily, 
    
    3) When given a choice, NASA likes to build new tools rather than
    use existing ones. The incredible array of ELVs they have used over
    the years, in some cases custom built for single missions, is a
    good example.
    
    The Soviets seem to prefer to use existing tools and technology
    wherever possible. However, in the past they have tried to carry this
    approach beyond its limits, e.g. the 'G' class booster they tried to
    build in the 60s and 70s. 
    
    
    Given the current crop of politicians and the apparent public
    attitudes, I can't see these conditions changing in the 1990s.

448.2Nasa needs insight and leadershipVICKI::SHIPPINGFri Aug 26 1988 14:3416
    The bottom line is, just as in the topic header;
    
    The United States accomplished what it wanted to do in the sixties
    and landed man on the moon.  It seems as though nobody knew where
    to go from there.  Mars?  It would take a human being six years
    to get there and return.  So we sent Viking I and II.  
    
    In the early seventies, NASA built up the Skylab program and it
    went well.  It seems like the last major accomplishment of the U.S.
    before the STS was the joint Soviet/U.S. linkup in '75.  Ironic,
    isn't it?  Much like the passing of the torch to the Soviets, in
    terms of leadership, anyway.  There was the Galileo project that
    fell through in the late seventies and early eighties as well.
    
    The space program simply needs the leadership it had in the early
    sixties, and an itinerary to follow.

    	GALILEO is not dead yet (the Jupiter probe, not the astronomer).
    It will be launched from the Space Shuttle in 1989, to encounter
    and orbit Jupiter in 1995, as currently scheduled (See Topic 280).

RELEASE:  88-172
 
    NASA'S OFFICE OF EXPLORATION RELEASES ANNUAL REPORT
  
     NASA'S Office of Exploration (OEXP) today released the first in
what will be a series of annual reports on the agency's planning
efforts and the nation's current capabilities for future human
exploration of the solar system.  The report, entitled "Beyond Earth's
Boundaries - Human Exploration of the Solar System in the 21st
Century," details OEXP's work over the past year to better understand
the efforts required to comply with the National Space Policy
directive to "expand human presence and activity beyond Earth orbit
into the solar system." 
 
     One of the major conclusions in the report is that independent of
what type of future exploration course is chosen, the United States
must now lay the foundation by beginning a modest but vital effort in
detailed research, technology development and concentrated studies in
addition to a sustained commitment to the current ongoing NASA
programs.  By pursuing a modest near-term investment of resources in
the 1990s in long lead technologies and capabilities, the U.S. will
preserve the ability to pursue a wide range of opportunities at the
turn of the century. 
 
     Among the critical ongoing programs identified in the report are
1) the completion of Space Station Freedom which will serve as the key
to developing the long duration capability to live and work in space,
2) the continuation of Project Pathfinder which builds the technology
base of the U.S. civilian space exploration program, 3) the pursuit of
a critical life sciences research program which will be the foundation
for long duration human habitation of space for both Space Station
Freedom and solar system exploration and 4) the continued development
of more capable Earth-to-orbit transportation systems to increase the
capability to transport equipment, propellant and personnel to
low-Earth orbit. 
 
     The report also identifies additional programs which must be
initiated if the U.S. is to maintain its exploration options. These
programs are in the areas of artificial gravity research and focused
flight test and demonstration program.  The artificial gravity
research must be started because if it is determined that an
artificial gravity environment is needed for exploration, that
requirement will have a significant impact on the space transfer
vehicle configuration.  The focused test program is needed to
understand and demonstrate the performance and capability of new
technologies such as aerobraking, cryogenic propellant handling in
space and highly advanced closed-loop- life-support systems. 
 
     To better understand the way all of these factors influence one
another, OEXP examined four case studies that encompassed a broad
range of objectives, requirements and capabilities.  All four addressed 
the prime directive of expanding human presence and activity beyond Earth 
orbit but, each emphasized a different pathway and destination. 
 
     One pathway examined is "Human Expeditions," which emphasizes a
significant, visible, successful effort by humans to accomplish the
first scientific exploration on another body in the solar system. 
This type of approach is applied to two different case studies; one
involving an exploration mission to Mars and the other an exploration
mission to the Martian moon Phobos. 
 
     A second pathway is "Science Outpost."  This approach also
emphasized the advancement of scientific knowledge while gaining
operational experience at an extraterrestrial outpost.  The case study
chosen involves a human-tended lunar observatory on the far side of
the Moon. 
 
     The final pathway studied is an "Evolutionary Expansion" approach
that involves a methodical, step-by-step program to open the inner
solar system for exploration, resource development and permanent human
presence.  This approach is applied to a case study using the
establishment of an outpost on the moon as a "stepping stone" to
similar outposts on Mars and its moons. 
 
     An in-depth discussion of this report is contained in a separate
three-volume series entitled "Exploration Studies Technical Report: 
FY 1988 Status," which will be available in early January 1989.

448.5Artificial Gravity?DECWIN::FISHERBurns Fisher 381-1466, ZKO3-4/W23Tue Dec 20 1988 12:594
Artificial Gravity research?  Does that mean spinning structures, or is someone
actually serious about a gravitron generator or some such?

    Ofcourse its spinning structures. We haven't even dectected a single
    graviton much less produced one,  nor are we likelly for a long time
    to come.
