NASA has announced the first crewed flight by a SpaceX rocket to the International Space Station (ISS) is expected to take place in June 2019. It will be the first manned U.S. launch to the orbiting research laboratory since the space shuttle program was retired in 2011, forcing U.S. astronauts to hitch costly rides aboard Russian Soyuz spacecraft. A flight on Boeing spacecraft is set to follow in August 2019. Both missions are considered tests: the two astronauts transported in each flight will spend two weeks aboard the orbiting ISS before returning to the earth. Later missions could last about six months.
