Fruit Flies Return Home from the ISS.Soyuz TMA-18 space vehicle successfully landed this weekend returned not only 3 crew members of the International Space Station, but also two containers with fruit flies. The flies born in zero-gravity are to help the scientists to study space impact risk mitigation for the genomes.The flies studied under Polygen experiment were chosen due to their reparation system which is similar to the human’s one. In addition, the flies propagate quickly, giving the scientists the opportunity to have much material for their work.Fruit flies were delivered to the station by Progress in mid September, 10 maggots in each of the two containers. Then, after oviposition of the flies hatched from the maggots, the second generation of the flies appeared. Several dozens of insects returned to the Earth last Saturday, in order to let scientists verifying their capabilities in zero-g, with the further on purpose to use the results for similar evaluations of the human body.Roscosmos PAO.www.roscosmos.ru/main.php?id=2&nid=10440&lang=en

Any word yet on what actually caused it to fail?
The S1 Truss PM unexpectedly failed on July 31st 2010, sparking an intense period of ISS reconfiguration, and development of procedures for what ultimately turned out to be three epic EVAs to R&R the failed Pump Module.According to the SSPCB notes, the failure investigation team are looking at “whether ammonia could have leaked into the pump motor stator area (sealed and filled with N2 normally)”, and will be determining “whether the ammonia flow was interrupted in the ‘secondary’ flow areas in the pump (used to lubricate and cool the bearings and friction surfaces)”.The notes also state that in late 2008, it was observed that the overall pump pressure was reduced, and that delta pressure (PSI-D) across the pump was showing a variance from nominal values. Current spikes were also noted during this period.The SSPCB were informed that the delta pressure and current draw data were not part of standard analysis in the past, but that they will be reviewed regularly in future as they may be useful for identifying possible pump degradation. It was also stated that 370mS (milliseconds) prior to the 54A current spike that occurred during the July 31st failure, the current draw from the pump went to zero Amps.
