NASA astronauts Robert Behnken and Douglas Hurley entered quarantine Wednesday, May 13, in preparation for their upcoming flight to the International Space Station on NASA’s SpaceX Demo-2 mission. They’ll lift off aboard a SpaceX Crew Dragon spacecraft carried by the company’s Falcon 9 rocket two weeks later at 4:33 pm Eastern Wednesday, May 27, from the agency’s Kennedy Space Center in Florida.
Due to the coronavirus pandemic, people all over the world recently have experienced varying degrees of quarantine – a period of isolation from others to prevent the spread of contagious illness. However, for crews getting ready to launch, “flight crew health stabilization” is a routine part of the final weeks before liftoff for all missions to the space station.
Behnken and Hurley will be the first American astronauts to fly to the station aboard an American spacecraft launched from American soil since the retirement of the Space Shuttle Program in 2011. The Demo-2 flight is an end-to-end test of SpaceX’s crew transportation system, part of NASA’s Commercial Crew Program. They’ll meet up with the Expedition 63 crew already in residence aboard the orbiting laboratory: NASA astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner.
Spending the final two weeks before liftoff in quarantine helps ensure the Demo-2 crew arrives healthy, protecting themselves and their colleagues already on the station.
Since Hurley and Behnken are training side by side and will be working and living as a team on the space station with their crewmates, they’re unable to maintain a six-foot distance. NASA’s quarantine rules are designed to protect astronaut crews while allowing them to continue working closely together, by limiting who can be in close proximity to them and ensuring they stay in environments in which their exposure to contagions or other hazardous materials can be tightly controlled in advance of their launch.
If they are able to maintain quarantine conditions at home, crew members can choose to quarantine from there until they travel to Kennedy Space Center. If for some reason they aren’t able to maintain quarantine conditions at home – for instance, if a family member living with them isn’t able to maintain quarantine because of their job or school requirements – they have the option of living in the Astronaut Quarantine Facility at Johnson Space Center until they leave for Kennedy Space Center.
Some additional safeguards have been added because of the coronavirus. For example, anyone who will come on site or interact with the crew during the quarantine period, as well as any VIPs, will be screened for temperature and symptoms. Hurley and Behnken, as well as those in direct, close contact with the crew will be tested twice for the virus as a precaution.
Health stabilization procedures were introduced for the Apollo program, in which NASA astronauts left low-Earth orbit to journey to the Moon, and have continued through the shuttle and International Space Station programs.
Behnken and Hurley will remain in quarantine after their arrival at Kennedy on May 20. Liftoff from Kennedy’s historic Launch Pad 39A is targeted for May 27 at 4:33 p.m. EDT.
