ISS Coolant Pump Restarted After Successful Spacewalks 19

Yesterday, two astronauts completed a seven hour spacewalk to finish installation of a spare coolant pump after a failed coolant pump forced a partial shut down of the ISS. As of late yesterday afternoon, that pump is online and operating normally: "The new pump now is considered fully functional, but it will take some time to fully reintegrate the pump and Loop A of the two-loop external cooling system. Teams at mission control are following a schedule that should allow the restored cooling loop to be fully activated and integrated into the station’s cooling system on Christmas Day, Dec. 25. ... Electrical systems that depend on cooling from Loop A will be repowered or moved back from temporary support on Loop B gradually on Thursday, Friday, and throughout the weekend."

      Space is cool again? That's cool.

        Sure, space is always cool, but in these liberated modern times we can twist it into a story about blokes who are living together in space.

        I shouldn't mention that, lest the ultra-conservatives conclude this is perverting the wide-eyed youth and decide the to slash the NASA budget.

    It is outstanding that they had the foresight to stock a replacement for what is apparently a very large, but crucial, component. I'm curious if anyone has heard whether there are plans to send them a new spare, just in case they go through this again? Was the original spare brought up via the shuttle and can a new one be brought up without the shuttle?

      An article in CSM noted that it weighs 780 pounds and is about the size of a refrigerator
      The first Space-x resupply mission carried nearly 2000 pounds... so weight is not an issue with putting another backup in place, not certain about dimensions
      The cooling pumps are part of the 'big 12' systems that must be running for the ISS to function. I would imagine that the backup plans have backup plans which have their own backup plans

  • They kept having problems with it and I'm much more interested in how they plan to resolve that set of issues.
