U.S. spacewalk 90 was cancelled 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. The crew is working with ground controllers to repressurize the crew lock section of the airlock before returning inside the station’s equipment lock.

Coverage continues on NASA+, NASA Television, YouTube, the NASA app, and the agency’s website. NASA will provide additional information on the space station blog.

The crew was scheduled to remove a faulty electronics box from a communications antenna on the starboard truss of the space station. The pair also intended to collect samples for analysis to understand the ability of microorganisms to survive and reproduce on the exterior of the orbiting laboratory.
