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. Skylab was launched in May 19, 1973. It rotated through three crews of three during its operational time. Skylab’s experiments confirmed coronal holes and were able to photograph eight solar flares. From 1986 to 2001, Russian space station Mir served as a permanent microgravity research laboratory in which crews conducted
Scientific research on the International Space Station Much like NASA and JAXA, ESA also conducted numerous experiments on the International Space Station. In May 2011, Space Shuttle Endeavour mission STS-134 carried 13 Lego kits to the ISS, where astronauts built models and saw how they reacted in microgravity, as part of the Lego Bricks in Space program. The results were shared with schools as part of an educational project. Scientific research on the International Space Station Scientific research on the International Space Station is a collection of experiments that require one or more of the unusual conditions present in low Earth orbit. The primary fields of research
