The four astronauts assigned to NASA’s SpaceX Crew-12 mission began a two-week preflight quarantine on Wednesday at NASA’s Johnson Space Center in Houston as the agency prepares for their upcoming launch to the International Space Station. NASA said the earliest launch window for the mission opens at 6 a.m. EST on Wednesday, February 11, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The Crew-12 team includes NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev. NASA said crew quarantine, a practice dating back to the Apollo era in the 1960s, reduces the risk of preflight illness and prevents health issues during the mission. During this period, crew members limit in-person contact, with most interactions conducted remotely.
