NASA has canceled a planned spacewalk at the International Space Station (ISS) due to a water leak in a spacesuit. Tracy C. Dyson, a NASA astronaut, discovered water pouring out of her suit and covering her visor with ice just moments after converting her suit to battery power. The leak was caused by a secret cooling unit attached to her suit. Dyson was able to plug the leak and get out of her suit in 45 minutes. This is the second time NASA has had to cancel a spacewalk mission this month due to spacesuit issues. Another spacewalk, scheduled for July 2, is uncertain at this time. In 2019, the first all-female spacewalk was postponed due to a spacesuit fit issue, and in 2022, spacewalks were suspended after water was found in an astronaut's helmet. NASA has not provided further details about the discomfort problem. The agency confirmed that all crew members on the ISS are healthy and spacesuits are functioning as expected. According to a recent article, NASA spacesuits have not evolved much since the Soviet era and the 1980s, and there is a need for updated spacesuit technologies [39843eee] [4516bdd7] [d86d7258] [664685fc].
