- Under that definition, spacelab is also operations, the gloveboxes and
- cameras on spacelab are operations, etc. Looked at differently, spacelab
- is a research *tool* purpose built to do research, and it can only do
- that with support from Shuttle which was built to carry things like
- spacelab.

- Well that would be *aeronautical* research, but that isn't the only
- kind of research being done with Shuttle. Shuttle itself is a long
- term testbed for reusable flight. It's already yielded valuable
- information on the problems and benefits of reusability in manned
- spacecraft. Purportedly, the DC program benefits from that knowledge.
- The continuing Shuttle improvement programs are development efforts.
- So R&D is ongoing with Shuttle. It would be very expensive R&D of course,
- if you were to count all of Shuttle's costs as R&D, but it's the only
- reusable manned testbed that is flying *today*. And, in the course of
- that flight R&D, other research programs like those on spacelab get
- supported at no extra cost. Or the cost gets split among all the
- Shuttle payloads, however you want to look at it. There are no ready
- flying alternatives to many of the Shuttle missions today, so you
- either fly Shuttle or declare a hiatus in manned space until something
- new is developed and tested. We went through that once before after Apollo.
- Many people think we should have kept plugging along with Saturn, Skylab,
- etc until Shuttle proved itself better, or if it was unable to show itself
- better, until an entirely different approach was developed and tested.
- But we didn't, and manned space efforts suffered as a result. We shouldn't
- make that mistake twice.
