The three astronauts and one cosmonaut on NASA’s Crew 12 flight to the International Space Station have entered quarantine in preparation for their upcoming launch in about two weeks. This is a normal step in the launch campaign, and is designed to reduce the chances of communicable diseases affecting the Crew 12 flyers as well as others already aboard ISS.

NASA astronauts Jessica Meir, Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev will remain in Houston until February 6th, when they are expected to fly to Kennedy Space Center for final launch preparations.

Launch Windows

NASA has also announced launch windows for Crew 12:

SpaceX Crew-12 Launch Windows
Mission	NASA/SpaceX Crew-12
Destination	International Space Station
Launch Site	SLC-40, Cape Canaveral Space Force Station
Window 1	Feb. 11 — 6:00 a.m. EST
Window 2	Feb. 12 — 5:38 a.m. EST
Window 3	Feb. 13 — 5:15 a.m. EST
Note	NASA continues working toward potential launch windows for both Artemis II and Crew-12 in February. Final launch dates will be determined closer to flight.

The launch will be the second crewed flight from SLC-40. Crew 9, carrying Nick Hague and Aleksandr Gorbunov, lifted off from the site on September 28, 2024, marking the second crewed launch from Cape Canaveral Space Force Station since Apollo 7 launched from LC-34. The ill-fated Boeing Crewed Flight Test (CFT) aboard Starliner was the first. The two CFT astronauts already aboard ISS, Butch Wilmore and Suni Williams, became part of Crew 9 once it was at ISS.
