NASA’s Artemis 2 astronauts prepare for launch in isolation

As NASA rolled it mega moon rocket Near the launch pad Thursday evening, astronauts preparing to ascend it watched the spectacle from screens in their quarantine facility.

From Wednesday evening, the Artemis II crew – Commander Reid Wisemanpilot Victor Glover, Christina Koch and Canadian Jeremy Hansen — reported to the Johnson Space Center in Houston to begin their mandatory two-week isolation.

It’s a defining moment for everything space mission, but one that the quartet has already experienced twice before for launch dates that came and went. The mission leaders attempted to launch the 10 day lunar trip since February, but crews continue to encounter problems requiring repairs. Now they are aiming for a launch window that begins April 1.

No one knows yet if the third quarantine will be a charm for Artemis II, but politics protect the crew and that their space flight is not derailed by daily germs. After all, Wiseman, Glover, Koch and Hansen will share extremely tight space in a sealed spaceship as they travel around the world. moon. The Orion capsule, which they named Integrity, is about the size of a studio. Even a mild virus could spread quickly among them.

“We choose to isolate the crew for 14 days before a launch because most infectious diseases take 10 to 14 days to spread from one person to another,” Dr. Raffi Kuyumjian, Canadian Space Agency flight surgeon, said in a video.

Medical teams test astronauts when they enter quarantine and again just before liftoff to try to detect any warning signs of illness.

If the idea of ​​long isolation seems bleak, know that quarantine rarely involves astronauts alone. Medical staff, support teams and technicians who work closely with them often join the protective bubble so as not to transmit anything either. Family members can also join.

NASA Quarantine History

Agency Policies have come a long way since the Apollo era. In the past, astronauts had to quarantine before and after returning from the Moon. These pioneers would remain isolated and monitored for 21 days after landing on Earth, in case they were exposed to any microorganisms in the lunar environment.

Their mobile quarantine facility consisted of a modified Airstream camper. The vehicle has been carefully filtered so that it cannot release anything harmful into the air.

It was not until 1971 that NASA ended post-flight quarantine procedures, following a recommendation from the Interagency Committee on Back Contamination.

Artemis 2 crew in quarantine

A week before launch, the crew will move to the group’s facility at the Kennedy Space Center in Cape Canaveral, Florida, for the final part of the quarantine. There they continue to train but mainly focus on relaxing. They go through final checklists, sit down with flight directors for final briefings, and complete their final medicals. They also spend what time they can with family before heading to the launch pad.

“They need to be well rested because the mission will be very busy,” Dr. Kuyumjian said.

But quarantine is really just a layer of defense to protect. crew health. Astronauts and support staff receive vaccinations, including against influenza and COVID-19to reduce the risk of these viruses boarding the spacecraft.

Launch delays can complicate the system. If the schedule extends by a day or two, astronauts generally remain in quarantine until the new launch time. But if a mission is postponed for several weeks or more, they come out of quarantine and then begin a new 14-day isolation before the next attempt.

In the rare cases where someone became ill in quarantine, they were usually mild respiratory infections that ultimately did not alter the mission. Only if the illness is serious will mission leaders consider delaying the launch or swapping astronauts.

This is a rarely used option, although Jack Swigert is a famous example of a last-minute Apollo 13 replacement. Just three days before the mission, NASA removed astronaut Thomas Mattingly from the mission due to his exposure to German measles. As history will show, Mattingly never got sick – but he also didn’t end up on that ill-fated flight, which nearly killed the crew.

“It didn’t take me very long to get rid of my hostility toward doctors,” Mattingly said in an interview for a 2001 oral history project. “They [had] has done me a very good service.”
