UT: Multiple Computer Failures on the ISS

Multiple Computer Failures on the ISS
Universe Today - 2010 Feb 21
The main computer on the International Space Station failed early Sunday, and subsequent multiple computer anomalies prompted communication blackouts. The one main computer has two backup systems, and NASA reported that the three command & control computers are switching between prime, backup and standby. A software issue is suspected, and diagnosis continues. The computer system is critical to all aspects of space station operation.

NASA reported that despite the computer issues, all ISS systems are performing normally and there are no concerns for the safety of the crew.

The 3 ISS "command & control" computers are switching between prime, backup and standby. A software issue is suspected. Diagnosis continues. (about 1 hour ago)

The ISS computer is working again. Any 1 of the 3 computers can be the primary. There always is a "hot" backup & the third is in standby. (about 1 hour ago)

A "command & control" computer failed on ISS around 9a ET causing a brief loss of communications. A backup computer kicked in & all is well. (about 1 hour ago)

ISS Computer Failure Knocks Out Communications Briefly

Space Station Computer Failure Knocks Out Communications Briefly
Space.com - 2010 Feb 21
A main computer failure aboard the International Space Station knocked out communications between the orbiting laboratory and Earth for a short time Sunday, but the station has since recovered, NASA officials said.

One of three command and control computers on the space station failed just before 9 a.m. EST (1400 GMT), but a backup kicked in as designed to restore communications with Earth after about an hour.

Since then, each of the three computers has suffered a so-called transition event, in which the primary computer shifts to a backup, but the space station's main control computers are currently all online, NASA officials said. The glitch has occurred four times.

Engineers currently suspect the computer problem may be due to commands sent from Mission Control at NASA's Johnson Space Center in Houston.

That's how it starts. Next thing you know, they'll be outside replacing the AE-35 unit. I wonder if the main computer in the ISS can read lips...
