Second spacewalk in a row called off due to spacesuit problems

by | Jun 24, 2024 | Science

Floating in the International Space Station’s Quest airlock module, veteran spacewalkers Tracy Dyson and Mike Barratt were preparing to head outside Monday to finish a spacewalk that was called off June 13 when Dyson reported a significant water leak from her spacesuit’s cooling system, saying “there’s literally water everywhere.”The leak was stopped when Dyson reconnected an umbilical that supplies station power, cooling water and oxygen. The airlock was repressurized, its inner hatch was opened and the astronauts moved into the airlock’s inner compartment where crewmates were standing by to help them out of their bulky spacesuits.NASA said Dyson and Barratt were never in any danger.Astronaut Tracy Dyson, wearing a spacesuit with red stripes, is helped back into the spacewalk staging compartment after a coolant leak prompted flight controllers to call off a planned 6.5-hour spacewalk.

Moments after the switch to battery power, the cooling water in Dyson’s suit began spraying out.”Oh, my goodness,” Dyson said when she noticed the water spewing out.”Oh, wow,” Barratt agreed.”Water is flowing out of my SCU (service and cooling umbilical), guys,” Dyson told flight controllers. The umbilical supplies cooling water, oxygen and electrical power until the crew member disconnects to exit the airlock.”There’s a lot of water flowing,” Dyson said, a moment later adding, “there’s literally water everywhere. … I’ve got ice all over my helmet.”The umbilicals were reconfigured and the leakage stopped.
