Russians suspected suit trouble from the start
.... but since the cosmonaut wasn;t complaining about overheating, they
decided no action was needed -- and didn't bother to tell the Americans at the TsUP either. "Moscow’s ‘Channel One’ television correspondent Ivan Yevdokimenko had reported in the noon Friday news program that “the fact that Aleksandr Kaleri’s spacesuit was not cooling off properly was spotted by Mission Control minutes after the space walk began.” Yet it wasn’t until three hours later, when Kaleri reported the “rain” inside his helmet, that Americans became aware of any problems." |

This seems to support the theory that the kink in the cooling line could have happened while putting the suit on. If that's the case, hopefully the Russians will come up with procedures to find such problems before stepping out of the airlock. You'd think that something simple like a flow meter (or monitoring the current used by the cooling pump) would work. Jeff -- Remove "no" and "spam" from email address to reply. If it says "This is not spam!", it's surely a lie. |

Jeff You verify proper flow the day before the EVA during the suit checkout process. A sputnik looking pump and flow gauge are involved. Once you're wearing the suit, you cycle the russian equivalent of the temperature control valve to verify cooling response, to make sure there are no bubbles or kinks in the cooling lines. Ground control can monitor the temperature response and, of course, the spacewalker can feel the response. So there really is a way to check these things. If the cooling line was kinked during the donning process, you should be able to find out about it during the 1/2 hour prebreathe before depress. -Cache! |
