Second ISS spacewalk done and dusted
Troublesome bolt delays installation of Ammonia Tank Assembly
Mission specialists Clayton Anderson and Rick Mastracchio today wrapped the second of three STS-131 mission spacewalks outside the International Space Station - a seven hour, 26 minute EVA during which they fitted a replacement Ammonia Tank Assembly (ATA).
The pair exited the ISS at 05:30 GMT, but after four-an-a-half hours had a spot of bother with one of four bolts designed to attach the ATA to the ISS's Starboard 1 truss.
The delay in getting the bolt in place meant that NASA "deferred the nitrogen and ammonia fluid connections and the retrieval of micrometeoroid debris shields that had been planned for this spacewalk".
Anderson (pictured) and Mastracchio did, though, wrap the electrical connections to the ATA, which forms part of the ISS's cooling system. ®
Listening to them this morning (via somafm.com/missioncontrol/) and they were having trouble with one of the laptops on board - wasn't booting into windows and kept giving the 'do you want to start in safe mode' prompt. Nice to see some things are consistent even in space...
Spacemen are cool.
Clayton Anderson's quote after performing the Ammonia Tank Assembly fix, "Urine it now!"
