NASA’s coverage is underway on NASA+, NASA Television, YouTube, the NASA app, and the agency’s website as two astronauts will conduct a spacewalk outside of the International Space Station. The spacewalk is scheduled to begin at 8 a.m. EDT and last about six and a half hours.

NASA astronauts Tracy C. Dyson and Matt Dominick 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. Dominick will serve as spacewalk crew member 2 and will wear an unmarked suit. U.S. spacewalk 90 will be the fourth for Dyson and the first for Dominick. It is the 271st spacewalk in support of space station assembly, maintenance, and upgrades.
