80's style Stations Modules...

These tended to have a longer design, filling up the entire payload bay of the Shuttle. Does anyone know why these longer modules were rejected in favor of the shorter ones now used on the ISS? The older designs certainly had much more room. Probably at least partly because longer ones would have been too heavy for the Shuttle to get to the high-inclination ISS orbit. In the eighties, the station was planned to be put at 28 degrees. But that's just a guess. Rand is right. Also $ was factor Actually, you're both wrong. The modules were shortened as part of the infamous "Fred" redesign of Space Station Freedom in 1991, two years before the Russians were brought into the project and the station's planned orbit moved from 28.8 to 51.6 degrees. Astronautix is normally suspect as a source, but their Fred article was guest-written by Marcus Lindroos and is fairly well researched: http://www.astronautix.com/craft/spanfred.htm "The length of the crew modules was reduced to 8.2 meters to reduce the weight while allowing them to be tested, integrated and outfitted on the ground rather than in space." Well, as I said, just a guess. I didn't follow the program that closely. |
