NASA employees were told to work from home Friday as a part of a systemwide test in case of an outbreak of the coronavirus.

Memos obtained by Politico shows the space agency’s employees – as well as select Air Force personnel – are advised to stay home to test remote work technologies in case federal employees are forced to work from home for an extended person of time due to the virus.

“As the coronavirus (COVID-19) situation continues to evolve, NASA is taking various actions to maintain preparedness,” Bettina Inclán, a NASA spokesperson, to Politico. “To that end, Friday, March 6, will be an agency-wide telework day. NASA centers and headquarters regularly perform telework drills to test our capabilities, resources, and preparedness for large-scale teleworking.”

No other federal agencies or military branches have announced similar plans at this time.

Inclan said the opportunity to work from home is voluntary. NASA centers, including Marshall Space Flight Center in Huntsville, will remain open. Contractors are asked to check with program managers about their schedules.

A memo from the Air Force said the employees as part of a “short-notice telework capacity test.” Employees will be asked to submit reports if they have technological or connectivity problems.
