NASA, SpaceX, and the United Arab Emirates are working together to launch a historic mission to the International Space Station on Monday. The four-man crew consists of two NASA astronauts, one Russian cosmonaut, and the first-ever UAE astronaut. This mission marks the first time that astronauts from all three countries will be working together in space, and is part of a public-private partnership between NASA and SpaceX to keep the ISS fully staffed and to return astronaut launches to US soil. It is also part of the UAE’s ambitious space program, and is expected to be a success.
