Los Angeles Times: During a third spacewalk at the International Space Station on Monday, NASA astronauts Doug Wheelock and Tracy Caldwell Dyson (shown here) successfully replaced the cooling pump that had broken on 31 July. The station uses two pumps to keep it from overheating; with one pump out of commission, the crew had shut down nonessential equipment to avoid taxing the system until the repair could be effected. Tests showed that the new pump was working and that everything should be back to normal in a few days.
