NASA’s first planned spacewalk of 2024 was abruptly canceled on Thursday, approximately an hour before its scheduled initiation at the International Space Station. The space agency cited a ‘spacesuit discomfort issue’ as the reason for the postponement, without elaborating on whether the problem affected one or both astronauts, Tracy C. Dyson and Matthew Dominick. The spacesuits utilized for spacewalks are known for their bulky nature, and an improper fit can pose a significant challenge during extended periods of time. Despite the unusual nature of such a cancellation, NASA emphasized that the crew and spacesuits remain in good condition. The next scheduled spacewalks are set for Monday, June 24, and Tuesday, July 2, with the astronaut assignments yet to be determined. The planned research, involving the swabbing of exterior surfaces to assess the survival of microorganisms released from the station’s vents, will be conducted during the Monday spacewalk, albeit slightly delayed.
