SCRUBBED - NASA - ISS Spacewalk #90 - Mike Barratt & Tracy Dyson - June 24, 2024

U.S. Spacewalk 90 was canceled Monday at the International Space Station due to a water leak in the service and cooling umbilical unit on NASA astronaut Tracy C. Dyson’s spacesuit. Dyson and Mike Barratt set their suits to battery power at 8:46 a.m. EDT and opened the hatch to the space station’s Quest airlock before reporting the water issue.

Coverage of U.S. Spacewalk 90 at the International Space Station. The spacewalk was scheduled to begin at 8 a.m. EDT, 12:00 UTC, 14:00 CEST, and last approximately. 6.5 hours.

The spacewalk will be hosted by NASA's Johnson Space Center in Houston, Texas.

NASA astronauts Tracy C. Dyson and Mike Barratt will exit the station’s Quest airlock to complete the removal of a faulty electronics box, called a radio frequency group, from a communications antenna on the starboard truss of the space station. The pair also will collect samples for analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory.

Dyson will serve as spacewalk crew member 1 and will wear a suit with red stripes. Barratt will serve as spacewalk crew member 2 and will wear an unmarked suit. U.S. spacewalk 90 will be the fourth spacewalk for Dyson and the third spacewalk for Barratt. It is the 271st spacewalk in support of space station assembly, maintenance, and upgrades.

U.S. spacewalk 90 was initially scheduled for June 13 but did not proceed as scheduled because of a spacesuit discomfort issue.
