NASA cancels ISS spacewalk due to spacesuit coolant leak.

NASA cancelled a spacewalk at the International Space Station today (June 24) following a spacesuit coolant leak in the hatch.

NASA astronauts Tracy Caldwell Dyson and Mike Barratt were told by Mission Control at 8:52 a.m. EDT (1252 GMT) to stop the planned 6.5-hour spacewalk outside the International Space Station (ISS). The pair had already switched over to the internal power in their suits at 8:46 a.m. (1246 GMT), meaning the spacewalk had technically started. Following the cancellation, astronauts opened the hatch into the ISS at 9:51 a.m. EDT (1351 GMT), officially ending the spacewalk. 

While being broadcast on a NASA Television livestream, they had reported "literally water everywhere" as they were moving their suits to internal power to prepare for the extravehicular activity. The leak appeared to be coming from a servicing and cooling umbilical (SCU) on Dyson's spacesuit, she reported. While the situation was serious, the astronauts were not in any danger due to the leak. 

NASA issued a brief official statement following the cancellation, adding that additional information will follow on the agency's ISS blog. They made the call to cancel as it was unclear how much water was left in Dyson's suit following the leak, as a precautionary measure, officials added on NASA Television.
