SpaceX had been awarded a contract from NASA for a spacecraft that is to deorbit the International Space Station in 2030, when its operational lifetime concludes. At a July 17th press briefing with NASA, SpaceX said it will help NASA accomplish this by creating an enhanced version of its Dragon spacecraft, known as the United States Deorbit Vehicle. It will be based on the original Dragon, but its trunk section will be redesigned and twice and long, with more thrusters. The final ISS crew will depart the station once the altitude reaches 330 kilometres, down from its present 400 kilometres as part of a natural decay in its orbit.
