- [example of hacker mentality as embodied in Jupiter vs. Vanguard
- launch vehicles moved to end.]
-
- I have a slightly different perspective on the space program, based
- on the material I've read.
-
- The whole civilian manned space program was essentially a hack. It
- was an outgrowth of the military's "Man In Space Soonest" program,
- colloquially known as "Spam in a can". Put someone up, bring someone
- down, no big technological deal. To many in the Air Force, the whole
- uproar over Sputnik was just a lot of noise. The USAF was well along
- in research and ready to start development on capability to maintain
- a continuous manned presence in space.
-
- To be fair, this was essentially a political hack, not a technological
- one. Quite possibly only the US had the brains and resources to
- pull it off in such a quick, dirty, and wasteful way.
-
- My opinion is if we had been rational about the whole thing, we would
- have kept the X-15 and Dyna-Soar programs funded, and been farther
- along in terms of having a *useful* space capability than we have
- now. The first manned space flight (space being altitude > 50 mi) was
- Yuri Gagarin in May 1961, with the first US manned flight later in 61.
- The X-15 made it into space in 1962, at what was probably lower cost.
- (Reusable launch vehicle, reusable spacecraft, no carrier task group
- needed for retrieval.)
-
- What was the moral of the fable? Slow and steady wins the race?
