NASA's Artemis II Crew Enters Quarantine Ahead of April Moon Mission
The four astronauts of NASA's Artemis II mission have begun a pre-launch quarantine as they prepare for a historic lunar flyby scheduled for April 2026.
NASA's Artemis II crew—comprising astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—has entered a pre-launch quarantine at the Johnson Space Center in Houston. This standard procedure aims to prevent exposure to illnesses that could jeopardize the mission. The quarantine is expected to last at least 14 days, aligning with the mission's targeted launch window beginning April 1, 2026.
The Artemis II mission marks the first crewed lunar flyby in over 50 years. The 10-day journey will test critical systems aboard the Orion spacecraft and the Space Launch System (SLS) rocket, paving the way for future lunar landings. The crew will travel approximately 4,700 miles beyond the far side of the Moon, setting a new record for human space exploration distance.
Recent technical challenges, including hydrogen leaks and a helium-flow issue, prompted NASA to conduct repairs and delay the mission from its original schedule. Following successful testing and a comprehensive flight readiness review, the agency has cleared the Artemis II mission for its upcoming launch.
During quarantine, the astronauts will continue mission simulations and medical checkouts. They are permitted visits from friends and family who adhere to NASA's health guidelines, such as avoiding public places and wearing face masks.
NASA plans to roll the 322-foot SLS rocket back to the launch pad at Kennedy Space Center in Florida on March 20, 2026, in preparation for the anticipated April launch.
