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
International Space Station The hatch leading into the module remains closed except for periodic visits by space station crew members for inspections and data collection. The module was originally planned to be jettisoned from the station following the test, but following positive data after a year in orbit, NASA has suggested that it could remain on the station as a storage area. The International Docking Adapter (IDA) is a spacecraft docking system adapter being developed to convert APAS-95 to the NASA Docking System (NDS) / International Docking System Standard (IDSS). IDA-2 was launched on SpaceX CRS-9 on 18 July 2016. It was attached
