International Space Station program with on-orbit refurbishment in mind. According to the Outer Space Treaty the United States is legally responsible for all modules it has launched. In ISS planning, NASA examined options including returning the station to Earth via shuttle missions (deemed too expensive, as the station(USOS) is not designed for disassembly and this would require at least 27 shuttle missions), natural orbital decay with random reentry similar to Skylab, boosting the station to a higher altitude (which would simply delay reentry) and a controlled targeted de-orbit to a remote ocean area. The technical feasibility of a controlled targeted deorbit into a remote
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
