How bad is the problem for the space station?
NASA space station program manager Mike Suffredini said Monday that this malfunction is among the top potential failures for the International Space Station. NASA has a list of 14 different malfunctions (called the “Big 14”) that are considered critical to the continued operation of the space station. This cooling system pump failure is on that list, but it is the first such failure ever to occur, Suffredini said.
