The International Space Station briefly lost contact with ground controllers yesterday because of a computer problem, but its commander said the crew was fine, Nasa said.
The glitch lasted just under three hours.
The agency initially said flight controllers in Houston were updating software on board the station’s flight computers when one of the station’s data relay systems broke down.
The primary computer that controls critical station functions defaulted to a backup computer, but it was not letting the station communicate with Nasa’s Tracking and Data Relay Satellites, the US space agency said.
Officials in Houston were later able to communicate briefly with the crew as the space station flew over Russian ground stations. They instructed them to connect a backup computer to begin the process of restoring communications.
And communications were restored nearly three hours after the initial breakdown, Nasa said in a tweet.
The International Space Station marked its 10th anniversary of continuous human occupation on Nov. 2, 2010. Since Expedition 1 in 2000, the space station has been visited by 204 individuals.
The current crew is made up six men: two Americans, three Russians and a Canadian.
