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
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
