NASA’s Artemis 2 crew was moved into quarantine on Friday to ensure their health and safety in the days leading up to the much-anticipated launch.
For the first time in over 50 years, NASA is preparing to send a crewed mission to the moon on the long-awaited Artemis 2 mission. The crew of four astronauts — consisting of Reid Wiseman, Victor Glover, Christina Koch, and the Canadian Space Agency’s Jeremy Hansen — will launch on the first crewed flight of the Space Launch System (SLS) rocket and Orion spacecraft as soon as February 6, 2026. The mission will take the crew on a ten-day journey around the moon and back to Earth, traveling farther than any previous crewed mission in human history and paving the way for a new era of human deep space exploration.
While the world awaits the countdown from the launch pad, for the crew, the journey has already begun. On Friday, Jan. 23, the crew entered into a 14-day quarantine period known as the health stabilization program (HSP) to ensure they are in good health for the duration of the mission.
The HSP has been a NASA standard procedure since the Apollo 14 mission in 1971, as the agency began planning for longer stays in space. Earlier missions had demonstrated the risks of illness when Apollo 7 commander Wally Schirra came down with a severe head cold just 15 hours into the flight, with the rest of the crew soon joining him. What followed has since been described as a “mini-mutiny” that resulted in crew members refusing to wear their helmets upon re-entry.
NASA remains flexible regarding the calendar. The launch could come as soon as Friday, Feb. 6, but an exact date has not yet been set. But by beginning the health stabilization program now, the agency preserves its options while testing continues for the rocket and spacecraft. Ahead of the February window, NASA is set to perform a “wet dress rehearsal” — a critical test where the rocket is fueled and the countdown is simulated. Depending on the results of this rehearsal, the crew could actually come out of quarantine and re-enter 14 days before a newly established launch date.
Over the ten-day mission, the crew will truly be on their own. However, in a news release, NASA officials noted that “during quarantine, the crew can continue regular contact with friends, family, and colleagues” if they also follow relatively strict quarantine procedures. Those in close contact with the astronauts (officially designated as “Group A”) are required to “avoid public places, wear masks, and maintain distance from others they come into contact with.” Astronauts are permitted to stay in their personal homes during quarantine as long as all cohabitants follow the Group A quarantine procedures. This bubble allows the astronauts to proceed with mission simulations and medical checkouts without the risk of picking up an illness that could ground the mission.
While the crew isolates in Houston, technical teams at the Kennedy Space Center are finishing their final checks. Work at Launch Pad 39B has already covered the SLS rocket’s mechanical power, fuel lines, and engines. If the February launch window holds, the astronauts will move to Florida about six days before liftoff, staying at the crew quarters in the Neil A. Armstrong Operations and Checkout Building. Meanwhile, recovery teams from NASA and the Department of Defense are out at sea, running final simulations to practice retrieving the Orion capsule and its crew from the Pacific Ocean after they return.
As the first crewed flight of the Artemis campaign, these ten days will be the ultimate test for the systems and hardware that human beings will need to survive deep space. Every mile the crew travels is a small step towards the more difficult missions to follow — missions that promise scientific discovery, economic opportunity, and eventually, the first human footprints on Mars.
