Spacex Crew - 2 Mission To Launch After April 20

US space agency NASA says it has scheduled the next launch of SpaceX's Crew Dragon capsule after April 20. The spacecraft will carry four astronauts to the International Space Station for a crew member rotation.
The launch will be operated by SpaceX, under contract with NASA, following the first launch last November.
The second mission will carry two NASA astronauts, together with one each from the Japan Aerospace Exploration Agency, JAXA, and European Space Agency, ESA.
The launch will take place at NASA's Kennedy Space Center in Florida. The crew members will stay on the International Space Station till this autumn.
NASA says the SpaceX Crew-2 mission members will overlap with the Crew-1 members who are expected to return in late April or early May.
Japanese astronauts Hoshide Akihiko with Crew-2 and Noguchi Soichi with Crew-1 who flew to the station in November, are expected to spend some time working together on the space station.
