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. A manned flight on Boeing spacecraft is set to follow in August 2019. The crews will be using new lighter spacesuits developed by SpaceX and Boeing.
It will be the first manned US launch to the orbiting research laboratory since the space shuttle program was retired in 2011, forcing US astronauts to hitch costly rides aboard Russian Soyuz spacecraft.
Both missions are considered tests: the two astronauts transported in each flight will spend two weeks aboard the orbiting ISS before returning to Earth.
In the long term, NASA will use SpaceX and Boeing to take astronauts to the ISS for regular missions, which last about six months. SpaceX will carry out an uncrewed test in January 2019, and Boeing in March 2019.
SpaceX will use its Falcon 9 rocket for its launch with a Crew Dragon capsule attached on top.
Boeing’s Starliner ship will be propelled into space by an Atlas V rocket made by the United Launch Alliance, a joint venture with Lockheed Martin.
