Space research days in the space station, but this achievement was quickly overshadowed since the crew died on reentry to Earth. Salyut 1 was intentionally deorbited six months into orbit since it prematurely ran out of fuel. Skylab was the first American space station. It was 4 times larger than Salut 1.

From 1986 to 2001, Russian space station Mir served as a permanent microgravity research laboratory in which crews conducted

It is expected to orbit for 800 years at an altitude of about . The first poem to be launched into orbit about the Earth was inscribed on the instrument panel of TRAAC. Entitled "Space Prober" and written by Prof. Thomas G. Bergin of Yale University, it reads in part: Transit Research and Attitude Control The Transit Research and Attitude Control (TRAAC) satellite was launched by the U. S.
