- Allan if you have looked at any of the information that has been put out
- about SSF in the last decade you will see that the PRIMARY mission of
- SSF is to be a laboratory in space. This applies to materials processing
- as well as biological sciences. The Astronauts will actually be in the
- role of highly paid and trained experiment tenders and guinea pigs for
- research that will help us understand how human beings adapt to long term
- weightlessness.

- Assert all you want but this is not the case. Spacelab began over ten
- years before Ronnie made his call for the Space Station. All scientists and
- engineers agree that precursor testing is an absolute necessity in perfecting
- the methodology and proper engineering for the experiments to enable them
- to be successful on station. I assert that this is what we in the computer
- world call subsystem testing. This subsystem testing enhances the reliablity
- of the total system by allowing the testing of the individual components,
- methodologies, and processes that will be used for Space Station Freedom or
- any other manned orbiting outpost for that matter.

- Allen building SSF or any other large structure in space is a mere engineering
- exercise that we learned long ago. There are no mysteries involved in the
- process. What the precursor missions of Spacelab, SpaceHab, COMET and CONSORT
- get us is a REASON for building these large structures in space. Without a
- reason for existence other than the mere effort of building the structure,
- we get yet another Apollo, and yet another boondoggle that is useless in
- helping to advance the knowledge, understanding, and welfare of the citizens
- of the United States and the world.

- I think you misunderstand the point Allen and the point of the original post,
- which had to do with precursors to SSF. The point of the precursors as I have
- and Bill has laid out is that without proper testing at an early stage of the
- process, which we do have in the programs that I have mentioned, you have
- a great mass of expensive metal in the sky that is simply useless for anyone
- other than the mechanical engineers who design them. Your analogy of the
- house is an apt one. A house may keep you warm and dry, but if it is empty
- or the television does not work and the bed is broken and the lights don't
- work you only have an empty shell which does nothing for the occupants or
- the people in general.
