WASHINGTON: The International Space Station lost communication with ground controllers yesterday but its commander said the crew was fine, NASA said.
It blamed a problem in a data relay system.
NASA said flight controllers in Houston were updating software on board the station’s flight computers when one of the station’s data relay systems malfunctioned.
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.
The International Space Station marked its 10th anniversary of continuous human occupation on Nov. 2, 2010.
