| Skylab NASA's Skylab space station Main article: Skylab Skylab was the first space station the United States launched into orbit.[23] The 100 short tons (91 t) station was in Earth orbit from 1973 to 1979, and was visited by crews three times, in 1973 and 1974.[23] It included a laboratory for studying the effects of microgravity, and a solar observatory.[23] A Space Shuttle was planned to dock with and elevate Skylab to a higher safe altitude, but Skylab reentered the atmosphere and was destroyed in 1979, before the first shuttle could be launched.[24] printable couponscheap generic 118iagra no prescription | |
