NASA Updates Coverage for US Spacewalks 90, 91 Outside Space Station

NASA will provide live coverage as astronauts conduct two spacewalks outside the International Space Station scheduled for Monday, June 24 and Tuesday, July 2.

The first spacewalk is scheduled to begin at 8 a.m. EDT June 24, and last about six and a half hours. NASA will provide live coverage beginning at 6:30 a.m.

NASA will stream the spacewalk on NASA+, NASA Television’s public channel, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.

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.

The second spacewalk is scheduled to begin at 9 a.m. July 2, and last about six and a half hours. NASA will provide live coverage beginning at 7:30 a.m. Astronauts will remove and replace a gyroscope assembly, relocate an antenna, and prepare for future Alpha Magnetic Spectrometer upgrades.

NASA will stream the spacewalk on NASA+, NASA Television’s public channel, the NASA app, YouTube, and the agency’s website.

Following the completion of U.S. spacewalk 90, NASA will provide an update with participating crew members for U.S. spacewalk 91. It is the 272nd spacewalk in support of space station.
