Despite a recent request from Trump, NASA astronauts Suni Williams and Butch Wilmore were already scheduled to return to Earth on a Crew Dragon capsule this spring

Two NASA astronauts flew to the International Space Station in June on Boeing's Starliner capsule. The test flight was planned for eight days but technical troubles forced the capsule to return empty.
