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
Space burial cremated remains into space and returned them to Earth. The first private space burial, Celestis' "Earthview 01: The Founders Flight", was launched on April 21, 1997. An aircraft, departing from the Canary Islands, carried a Pegasus rocket containing samples of the remains of 24 people to an altitude of 11 km (38,000 ft) above the Atlantic Ocean. The rocket then carried the remains into an elliptical orbit with an apogee of and a perigee of , orbiting the Earth once every 96 minutes until reentry on May 20, 2002, northeast of Australia. Famous people on this flight included Gene Roddenberry
