The spacecraft that will be used for the task is the SpaceX Crew Dragon, a vehicle that has already proved its worth by journeying uncrewed to the ISS and back more than a year ago.
Two astronauts will fly on board the Dragon in May, Doug Hurley and Bob Behnken. The duo will go through all the flight's stages, including launch from the Launch Complex 39A at NASA’s Kennedy Space Center in Florida, docking with the ISS in orbit, splashdown and recovery from the middle of the ocean. If all goes well, the Crew Dragon will then be certified as safe for more flights, and a flood of missions will likely follow.
Having set the general date for the launch, NASA adds though that it all boils down to how the world will look like two months from now. In regards to the coronavirus pandemic, the agency states ”it will continue to follow guidance from the Centers for Disease Control and Prevention and the agency’s chief health and medical officer and communicate any updates that may impact mission planning or media access, as they become available.”
