[b]Spacewalk canceled due to water leak[/b] U.S. spacewalk 90 was cancelled on Monday (June 24 due to a water leak in the service and cooling umbilical unit (SCU) on Tracy Dyson's spacesuit. Dyson and Mike Barratt set their suits to battery power at 8:46 a.m. EDT (1246 GMT) and opened the hatch to the space station's Quest airlock before reporting the water issue. "Oh my goodness," said Dyson. "Water is flowing out of my SCU guys." "Yeah, there is a lot of particulates floating around here," added Barratt. "There is water everywhere in here." "Tracy, if you can reconnect your SCU to the DCM [Display and Control Module], that is the best way to stop this," radioed capcom Stephen Bowen from Mission Control in Houston. Once Dyson reconnected her spacesuit cooling unit, the leak stopped but she had to deal with ice on her gloves and concerns about where other ice deposits had formed. Dyson closed the airlock hatch. Dyson and Barratt worked with ground controllers to repressurize the crew lock section of the airlock before returning inside the station's equipment lock. Monday's spacewalk had a duration of 31 minutes, officially ending at 9:17 a.m. EDT (1317 GMT). Dyson has now logged 23 hours and 20 minutes on four EVAs. Barratt now has spent 5 hours and 37 minutes on three spacewalks. This was the 271st EVA in support of the assembly and maintenance of the International Space Station and the second this year.
