HOUSTON (AP) - Russian cosmonauts on Saturday began turning back on some crucial systems that had been shut down more than four days ago when a computer system on the Russian side of the international space station crashed.
The first system turned on was a machine that scrubs carbon dioxide from the air inside the space station.
Just a day earlier, Fyodor Yurchikhin and Oleg Kotov were able to get four of six processors on two computers working again by using a cable to bypass a circuit board.
It took four days to restore the capability of the computers.
“In the last 24 hours, we’ve had a lot of successes,” flight director Holly Ridings said Saturday morning.
The computers on the Russian side provide oxygen and maintain the space station’s correct position in orbit, allowing it to point its solar arrays at the sun for power and shift orientation to avoid occasional large debris that comes flying through space.
The computer problem had raised the possibility the space station’s three-person crew might have to abandon the outpost. NASA officials rejected such a scenario.
“We feel like the computers are stable and back to normal,” said Mike Suffredini, NASA’s manager of the space station program.
The cosmonauts may use another jumper cable Saturday to get the last two failed processors on the computers working, Ridings said Saturday morning.
Suffredini, however, said Friday night that engineers don’t expect the other two processors to come back online. They will be replaced.
Engineers were still trying to determine what prompted the power switch to cause the computers to fail, Suffredini said.
Early Saturday, U.S. astronaut Sunita Williams set the record for the longest single spaceflight of any woman by passing astronaut Shannon Lucid’s record of 188 days in space.
The seven astronauts visiting on space shuttle Atlantis and the three space station crew members planned to spend most of Saturday moving supplies and trash back and forth between the vehicles and preparing for the mission’s fourth spacewalk on Sunday.
For now, Atlantis is set to land at Cape Canaveral, Fla., on Thursday. But Suffredini said NASA officials were still deciding whether to keep the shuttle at the station an extra day because of the computer problem.
During the failure, the shuttle’s thrusters helped control the station’s position. Some of Atlantis’ lights, computers and cameras were turned off to save energy in case the shuttle had to stay an extra day.
NASA officials said the crew was never in danger of running out of oxygen, power or essentials.
The 11-day space station construction mission had already been extended by two days so a rip in the shuttle’s thermal material could be fixed.
The failed computers were the latest technical glitch for the half-built, $100 billion outpost. A Russian oxygen machine and gyroscopes, which also control orientation, have previously failed.
The computer problem renewed criticism of the space station, which has been called an ill-conceived venture, as well as criticism of President Bush’s “Vision for Space Exploration,” which calls for finishing the space station in three years, grounding the space shuttles in 2010 and building next-generation vehicles to go to the moon and Mars.
“We’re learning a great deal from the space station, and one of things we may be learning is we shouldn’t have built this particular one,” said Howard McCurdy, a space public policy expert at American University.
Two spacewalking Atlantis astronauts accomplished another critical task Friday: repairing a torn thermal blanket that helps protect the shuttle from heat on its return flight to Earth.
Danny Olivas used a medical stapler to successfully secure in place the 4-by-6-inch corner, and James Reilly installed an external valve.
During the nearly eight-hour spacewalk, astronauts also finished folding up a 115-foot solar wing on the space station. It took several days to put away the wing, which needed to be retracted to make way for a newly installed pair of power generating wings.
Associated Press writers Mike Schneider in Houston, Vladimir Isachenkov in Korolyov, Russia, and Seth Borenstein in Washington contributed to this report.
At this point in time, are we just wasting our money on supporting this adventure? We risk lives regularly to support the ship.
OK, Sergei .... crank it!
I think you could say that about everything we're doing.. ;)
"Open the pod bay doors, HAL"
Should have bought a Dell....
Some of us thrive on taking risks and get out of bed in the morning. ; )
This is good news, but in the longer view we are a long ways from the reliability needed for a manned trip to Mars and back. The Centaur apparently misfired slightly yesterday and that is one of the most reliable rocket systems ever. The satellite will probably have enough internal fuel to reach its orbit on its own, but mission lifetime will be limited.
Didn’t you hear Bradbury on Coast last night, or don’t you agree with him?
Were learning a great deal from the space station, and one of things we may be learning is we shouldnt have built this particular one, said Howard McCurdy, a space public policy expert at American University.
He says this after we’ve spent $100 billion dollars and it is only half built.
"OK, Sergei .... crank it!
Right away I noticed the obvious lack of an antistatic wrist strap being used in that picture.
No wonder they are having so many problems. LOL!
It took four days to restore the capability of the computers.
That 'award winning' Dell Tech Support from Bangladesh strikes again.
(after 45 minutes on hold)*#&%&* Dell.
"Hi, my name is 'Tommy'. Do you have a firewall? Did you install any software? No, Okay - first, unplug your computer and wait 30 seconds then plug it in and re boot ..... Alright then, did that fix it?."
"NO?" Oh well, I think we have to reformat your hard drive."
We are in space. In a spacestation. I think that is so cool.
Baby steps. Expensive but baby steps nevertheless.
May take us another 200 years to get to Mars. So?
I had a Dell from Hell. My Dell File (hard paper copies ) is over a 1/2" thick of junk that crapped out and had to be replaced. It was so bad I even had Dell replace stuff AFTER the warranty expired when I casually mentioned I just might contact the IL Attorney General under the Lemon Law.
So anytime I read of computers crashing, I think Dell.
So now I'm on an American Made, with American tech support Systemax p.c. - all in good ole Ohio, USA.
[My Dell crashed more than a blind man in a Demolition Derby.]
THIS is why we need people in space. Let’s see a remote robot probe fix itself by bypassing circuit boards. There is still no replacement for a real, honest-to-goodness “meat world” human being.
