Astronauts aboard the international space station and space shuttle Atlantis woke up to a worrying sound -- alarms representing a fire and dangerous loss of pressure, NASA said Friday.
However, a check revealed no serious problem.
Depressurization-caution alarms sounded just after 8:30 p.m. ET Thursday, waking the shuttle and station crew, NASA added. The flight control teams on the ground determined there was no depressurization as well as shut off ventilation fans.
The crew was never in any danger, NASA added, and teams on the ground are looking into the cause of the false alarm.
Flight control teams at Mission Control in Houston in Texas, were bringing the station back to normal soon after the alarms, but it was 10:15 p.m. at that time the crew was able to go back to sleep because they have to wait for the station's ventilation system to be reactivated, NASA added.
Crew members go back to work Friday when they will be focusing on preparations for Saturday's spacewalk, NASA added. They'll have to recharge batteries, switch out spacesuits and review procedures.
They also use the shuttle's robotic arm to grab a second cargo pallet of spare equipment Atlantis brought up in advance of its transfer to the space station Saturday, NASA added.
