NOVA: Operation Space Station Science and Survival

Attitude Control (I get it)

I completely forgot about NOVA last night:

The second NOVA program on the ISS had two interesting survival episodes. The first was where an EVA astronaut's helmet starting filling with water from a leak in the cooling system of his suit. They finally got him inside OK. The suit helmet now has absorbent pads and an emergency snorkel (!) to guard against a water leak. They mentioned that his suit had a CO2 alarm go off but they didn't mention (that I noticed) whether that alarm was related to the water in the helmet.

The second survival episode shown was when a Russian science module was docked to the ISS - it then began firing it's thrusters and causing all kinds of problems. The Russians never really quite figured out how to stop the thruster firing, the Russian module eventually ran out of fuel for the thrusters ! That's like the Bugs Bunny WWII cartoon where he is on a plane doing a power dive but right before he crashes the plane runs out of fuel and stops :)
