SpaceX is set to launch NASA’s four-person Crew-12 mission to the International Space Station. Liftoff will occur in a Crew Dragon atop a Falcon 9 rocket from Space Launch Complex 40 in Cape Canaveral, Florida.

Aboard will be NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev.

The four will dock with the space station’s Harmony module about a day after launch. They are expected to remain aboard the ISS for about nine months.
