What: NASA astronauts Jessica Meir and Chris Williams will conduct a long-delayed spacewalk to prepare a power channel for a future iROSA solar-array installation.
When: The EVA is expected to begin at 8 a.m. EDT (1200 GMT) and last about 6.5 hours; live coverage begins at 6:30 a.m. EDT (1030 GMT).
Background: The spacewalk was postponed after a Crew-11 medical evacuation in January; officials say the affected astronaut is recovering and doing fine.
Two NASA astronauts will perform a long-delayed spacewalk today, and live coverage is available for viewers who want to follow the operation in real time.
Who: Jessica Meir and Chris Williams will exit the International Space Station (ISS) to conduct an extravehicular activity (EVA).
When: The spacewalk is expected to begin at about 8 a.m. EDT (1200 GMT) and last roughly 6.5 hours. Live coverage, provided by NASA, starts at 6:30 a.m. EDT (1030 GMT).
Viewers can watch live via Space.com’s coverage or directly through NASA’s broadcast channels (NASA TV and the agency’s website).
The EVA was originally scheduled for early January but was postponed after a member of SpaceX’s Crew-11 mission experienced a medical issue while aboard the station. That situation prompted Crew-11 to leave the ISS on Jan. 15—about a month earlier than planned—which marked the first medical evacuation in the station’s history. Astronaut Mike Fincke later confirmed he was the Crew-11 member affected; neither he nor NASA has released details about the condition, but officials say the astronaut is doing fine.
Meir (on her fourth EVA) and Williams (making his first) will prepare one of the station’s power channels for the future installation of an iROSA (International Space Station Roll-Out Solar Array). A follow-up EVA with similar objectives is planned; NASA will announce the crew and target date after today’s EVA is complete.
These two upcoming spacewalks will be the first ISS EVAs of 2026, mark the first EVAs for Expedition 74, and will count as the 278th and 279th spacewalks in the station’s operational history.
NASA and partner teams continue to prioritize crew health and mission safety while maintaining the station’s operations and upgrades.
