The procedure to ensure that astronauts don't bring an illness to the International Space Station is under evaluation as NASA enacts tactics to help slow the spread of the novel-coronavirus disease COVID-19.
Governments and agencies around the world have been enacting measures meant to contain the spread of the novel coronavirus; those measures include social distancing and quarantines for people who think they may have been exposed to the virus. But these tactics aren't new territory for NASA astronauts, who take such measures to prepare for close-quarter, secluded living that can last six months or longer.
NASA and its international partners mandate that soon-to-be spacefarers stay in quarantine for two weeks before launching into space. This is done in order to ensure that they are not sick or incubating an illness when they reach the orbiting lab.
As Brandi Dean from NASA's Public Affairs Office explained in an email to Space.com, this procedure is called "health stabilization."
The procedure is especially important for astronauts because day-to-day living in microgravity can affect the immune system.
Dean said there are no astronauts currently close enough to their launch for standard prelaunch quarantine. (The next crew, comprising NASA astronaut Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner, is scheduled to launch on April 9.)
Beyond the typical spaceflight health measures, NASA is "closely adhering" to the infection-control recommendations made by the Centers for Disease Control and Prevention (CDC) to combat the spread of the novel coronavirus that causes the disease COVID-19, Dean said.
"This includes cleaning of surfaces, social distancing, emphasizing hand hygiene, encouraging NASA team members who are sick to stay home and limiting contact with crewmembers," Dean said.
Due to COVID-19, the space agency is currently evaluating changes to the standard health-stabilization plan. According to SpaceNews, Russia's space agency has suggested lengthening the quarantine for the trio launching in April, and NASA officials are discussing the measure with their counterparts.
"We expect them to take additional measures to make sure that quarantine is a little tighter," Kirk Shireman, ISS program manager at NASA, told Space News. "We're ready to deal with that if it happens."
NASA's virus-slowing measures extend beyond the astronaut corps. Most notably, the agency's Ames Research Center in California is "temporarily on mandatory telework status, with restricted access to the center until further notice," according to a NASA statement issued on Monday (March 9). That statement came after the agency received confirmation that an employee at Ames tested positive for COVID-19.
