Artemis II Prelaunch Quarantine Keeps Crew Isolated Ahead of Moon Mission

NASA’s Artemis II crew—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—are in a 14‑day Health Stabilization quarantine in Houston to prevent Earth microbes from reaching the Orion spacecraft and the Moon. They must avoid public spaces, outside air, and close contact, with masks and strict isolation, as NASA shifted the launch window to March 6–11 and the mission—lasting at least 10 days—will unfold in cramped quarters with limited comms. The policy harks back to Apollo-era quarantine to guard against cross‑contamination to the Moon’s pristine regions, and NASA recently faced an ISS mission abort due to a medical emergency.
