NASA has rescheduled a cancelled spacewalk outside the International Space Station (ISS) and will provide live coverage of it and a second spacewalk.
NASA astronauts Tracy C. Dyson and Mike Barratt will go outside the ISS at 10.00 p.m. (AEST) on June 24, with NASA beginning coverage 90 minutes prior.
The second spacewalk is scheduled to occur at 11.00 p.m. (AEST) on July, with coverage also starting 90 minutes beforehand. Both spacewalks are estimated to take around six and a half hours to complete.
In the first spacewalk, the two astronauts 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 one and will wear a suit with red stripes. Barratt will serve as spacewalk crew member two and will wear an unmarked suit. US spacewalk 90 will be Dyson’s fourth spacewalk for Dyson and Barratt’s third. It is the 271st spacewalk in support of the ISS assembly, maintenance, and upgrades. Spacewalk 90 was cancelled on June 13 because of a spacesuit discomfort issue.
On the second spacewalk, Dyson and Barratt will remove and replace a gyroscope assembly, relocate an antenna, and prepare for future Alpha Magnetic Spectrometer upgrades.
NASA will stream both spacewalks on NASA+, NASA Television’s public channel, the NASA app, YouTube, and the agency’s website.
