Some more briefings today about Russian segment emergency response, in particular about the depressurization scenario.
First big action: calculate how fast the pressure inside the Station is dropping and then figure out how much time you have before you need to evacuate. We call that reserve time.
Second thing: make sure that it’s not your Soyuz that is leaking. At least you know that you have a safe ride home.
After that: find the leak and isolate it. We have procedures that lead us through a systematic isolation of portions of the Station: every time we close a hatch we can determine on which side the leak is, until we pinpoint it to one specific module. We can then isolate it and preserve the rest of our pressurized volume.
Now, as you can imagine I am not talking here about movie-style leaks with things and people being drawn out to space. The location of the leak would be quite obvious in that case and you would have different priorities anyway!
After talking Station leaks in the morning, Anton and I had a leak in the engine piping during our afternoon Soyuz sim and as we performed the emergency reentry we got to fight various computer and engine failures.. The picture I’m sharing was taken another time though: that day Terry was with us as well and our crew was complete!
