End of mission Originally the ISS was planned to be a 15-year mission. Therefore, an end of mission had been worked on, but was several times postponed due to the success and support for the operation of the station. As a result, the oldest modules of the ISS have been in orbit for more than 20 years, with their reliability having decreased. It has been proposed to use funds elsewhere instead, for example for a return to the Moon. According to the Outer Space Treaty, the parties are legally responsible for all spacecraft or modules they launch. An unmaintained station would pose an orbital and re-entry hazard.
