they were able to get it restarted again. but they are troubleshooting the issue. the problem is they aren't able to provide enough cooling for the entire space station now because the one restarted is not working at 100%. so they had to shut down the non-critical system in three of the modulars on the station, the u.s. harmony modular, the european colombia and japanese modular. you mentioned it happen problems with this before. in fact, back in may they had to replace a pump on the international space station on the outside of the space station and require spacewalks to do it. and the pump that was the replacement pump is the one that's now not working again, so it could come to the point where they have to do another spacewalk to either replace this pump, have three spares on the station.
