Astronauts To Repair Cooling System On ISS

GWMAW writes "NASA Astronauts will conduct a spacewalk on Thursday to repair part of the cooling system of the International Space Station. The cooling system is essential for maintaining the temperature inside the station. There are two 'loops' in the system, one that uses water and draws heat from the inside of the station, and one uses ammonia and dumps the heat into space. Ammonia is used because it freezes at a much lower temperature than water. On Saturday the pump that controls the flow of ammonia through the system shut down."

Dear troll, it depends on whether you are on the light side or dark side. You'd be losing your heat via your body's radiation.

From NASA article Staying Cool on the ISS:

Without thermal controls, the temperature of the orbiting Space Station's Sun-facing side would soar to 250 degrees F (121 C), while thermometers on the dark side would plunge to minus 250 degrees F (-157 C). There might be a comfortable spot somewhere in the middle of the Station, but searching for it wouldn't be much fun!

Oh come off it GP is not trolling. Temperature is always a matter of perspective, even in the room where I am now. If your spacecraft decompressed you would feel cold because of adiabatic expansion. Stand or float in the sun and you will feel warm, but radiation would still be cooling you.
