| NASA Astronauts to conduct spacewalk to investigate microorganisms on ISS |
Unlike typical NASA spacewalks at the International Space Station (ISS) that focus on upgrades or maintenance, the one scheduled for Thursday, June 13, aims to investigate the presence of living organisms on the station's exterior.
Though the concept might evoke images of a sci-fi thriller, it's unlikely that the findings will be dramatic or alarming.
During the spacewalk, NASA astronauts Tracy C. Dyson and Matt Dominick will collect samples to study how microorganisms survive and reproduce outside the ISS. Additionally, they will remove a malfunctioning radio frequency group from a communications antenna on the starboard truss, according to NASA.
This will be the 90th U.S. spacewalk at the ISS, the fourth for Dyson, who arrived in March via a Soyuz spacecraft, and the first for Dominick, who also arrived in March aboard a SpaceX Crew Dragon as part of Crew-8.
NASA will provide live coverage of the spacewalk preparations starting at 6:30 a.m. ET, with the spacewalk commencing at 8 a.m. ET. The event will be streamed on NASA+, NASA Television, the NASA app, YouTube, and NASA’s website, and viewers can distinguish Dyson by the red stripes on her spacesuit, while Dominick's suit will be unmarked.
The spacewalk is expected to last approximately six and a half hours, allowing ample opportunity to watch throughout the day. If missed, additional spacewalks are scheduled for Monday, June 24, and Tuesday, July 2.
