This has the potential to be very serious. However, there may be ways around it.
The good thing is they have time on their side. Let's hope everything works out over time.

At first they thought it may have been a 'dirty porwer' problem related to the new solar array, but have since ruled that out.

Lets hope the problem is found and can be retified, it would be a devastating blow to loose ISS.





HOUSTON, Texas -- NASA has no problem leaving an astronaut and two Russian cosmonauts on the limping international space station despite a serious computer meltdown, a U.S. space agency official said Friday.

"I think we're in good shape. We've still got a lot of options to work through," space station program manager Michael Suffredini said in an afternoon briefing.

He said there was no urgency now that would require the crew of the orbiting outpost to come home. "We have plenty of (oxygen) gas to keep the crew on orbit for some time," Suffredini said.

He refused to speculate about prospects long-term if the computers aren't back in service.

Meanwhile, two astronauts from the space shuttle Atlantis, which arrived one week ago to continue construction work on the space station, began a spacewalk with two assignments: to disconnect a connector on a newly installed power-conducting truss that is a key suspect in the computer glitch, and repair a torn thermal blanket that helps protect the shuttle from heat on its return flight to Earth next week.

NASA suspects the connector because the Russian computers blinked out at about the same time the connector went on line. The connector isn't required for station operations until a later power hook-up, Suffredini said.

"It's circumstantial,' he said. "We don't know if that's the cause."

Russian computers...

Ufff, I am not sure it was a good idea to let russians to set up such a critical enviromnet. Russian computers sounds like nonsens. At least when I was living in Russia, all the technologies were delayed by 20 years comparing with Europ and USA.

Well, they seem to have solved the problem or at least lessened it.

However, I agree with you if the technologies are not up to par, it absolutely should not be used on critical systems. To do so just invites major problems or worse. This is by no means confined to the ISS, this should apply to anything that could have severe consequence.

But then sometimes I wonder how many of these decision are politically motivated rather than scientific.
