[highlight]Space Station Suffers Cooling System Malfunction[/highlight] [url=http://www.space.com/missionlaunches/space-station-cooling-malfunction-100801.html]Source[/url] [release]The International Space Station suffered a cooling system malfunction late Saturday that forced its astronaut crew to power down some vital systems while engineers on Earth study the problem. A power spike led to the shutdown of a pump module in one of two liquid ammonia cooling loops on the space station, setting off alarms that awoke the six astronauts living aboard the orbiting lab, NASA officials said in a statement. The malfunction occurred Saturday at about 8 p.m. EDT (0000 Sunday GMT) while the crew was sleeping. Once awake, space station astronauts powered down some attitude control systems, as well as redundant communications and global position system gear to balance the heat loads on the outpost's backup cooling system, which is working well. "The crew is in no danger, but will need to work additional troubleshooting on Sunday to keep the station in a stable configuration, including the installation of a jumper cable to maintain proper cooling to the Zarya module in the Russian segment," NASA officials said. The International Space Station is currently home three American astronauts, representing NASA, and three cosmonauts with Russia's Federal Space Agency. Most of the crew returned to sleep after powering down station systems in response to the glitch, though American astronaut Tracy Caldwell Dyson remained awake well into the wee hours of Sunday morning to help Mission Control troubleshoot the malfunction. In all, the astronauts shut down two of the station's four American control moment gyroscopes, which are used to adjust the orbiting lab's orientation in space without using thrusters. They also turned off an S-band communications systems, a GPS system, several power current converters in the station's Tranquility module (a room that houses much of its life support gear) and some gear that routes commands to other parts of the space station. The pump module malfunction affected the space station's Cooling Loop A only, with the backup Cooling Loop B working as designed, NASA officials said. The space station is also equipped with two spare pump modules should a replacement be required in a future spacewalk. They are stored outside the station on spare parts platforms attached to the orbiting laboratory's backbone-like main truss. Astronauts have been living aboard the $100 billion International Space Station, which is being built by five international space agencies representing 16 different countries, for nearly 10 years. Construction began on the orbiting laboratory in 1998. NASA plans to fly two space shuttle missions (in November and February, respectively) to complete construction of the space station before retiring the shuttle fleet next year. Congress is discussing the possible addition of a third and final shuttle mission, which if approved would likely carry spare parts and other supplies to the space station in next summer. [/release]
i wish i was an astronaut.
In regards to Oxygen on the space station, do they have to keep sending up Oxygen tanks to there?
How long have the current occupants been in it for?
I hope nothing serious happens.

[QUOTE=xianlee;23760407]In regards to Oxygen on the space station, do they have to keep sending up Oxygen tanks to there?[/QUOTE] I would assume they have some kind of oxygen converters, even large tanks of oxygen would never last between resupplies.

[QUOTE=Tetracycline;23761725]Plants everywhere I bet[/QUOTE] you need an acre of trees to support a person. might be a bit smaller but you can't support multiple people like that on such a small space. there are probably plants but the air they scrub is minimal the air in the ISS comes from tanked oxygen for emergencies and from electrolysis of water. the drinking water from the astronauts comes from a scrubber that burns co2 and hydrogen to create water and a few other waste products. and the waste water from bathrooms and showers is put through electrolysis and turned into oxygen, starting the cycle over it's not contained but the iss was never designed to be
I think if I was on a space station, the last thing I would want to wake up to was fucking alarms going off.
If anyone can fix it it's these guys: [img]http://alltopmovies.com/wp-content/uploads/2009/07/tn2_apollo_13_4.jpg[/img]

[QUOTE=petieng;23760844]Being woken up by a malfunction alarm on the space station would be pant-shittingly scary.[/QUOTE] Oh yeah. But at the same time, they'd probably know that anything INCREDIBLY dangerous would probably have already killed them.

God that would be scary. Would be sort of scary anyway, being isolated thousands of kilometres from earth...
[QUOTE=Assburgers;23778948]God that would be scary. Would be sort of scary anyway, being isolated thousands of kilometres from earth...[/QUOTE] They're not thousands of kilometres away from earth, likely much below 100 kilometres.
[QUOTE=carcarcargo;23780888]They're not thousands of kilometres away from earth, likely much below 100 kilometres.[/QUOTE] under 100km wouldn't be in space, because 100km is where the "imaginary line" between earth and space is this ISS is about ~390km up (i think) and is orbiting the earth fast enough to go around the world in 90 minutes i would be terrified to be on that thing if anything went wrong
The ISS varies from 340-350 KM, depending on where in its orbit it is, And worst case scenario they could always use the emergency return vehicle, or we launch within a couple months a shuttle to retrieve them
[QUOTE=Sparkwire;23760340]i wish i was an astronaut.[/QUOTE] Dude, I want to be a fucking space miner. I wouldn't give two shits about visiting the ISS then, I would be mining space asteroids in space.
