NASA Sets Spacewalk for Station Maintenance, Live Coverage Planned
Astronauts Jessica Meir and Sophie Adenot will perform a spacewalk on Sept. 1 to maintain the International Space Station. They will replace a navigational aid and complete other operational tasks.
Why it matters
The mission ensures spacecraft can safely navigate and dock with the station by replacing a retroreflector. This maintenance prevents failures during critical docking operations.
The big picture
This maintenance follows NASA's recent use of the station to study a solar eclipse on Aug. 12, 2026.
The details
- Astronauts will install jumper cables for data-relay systems. - The crew will prepare the Alpha Magnetic Spectrometer’s radiator. - A high-definition camera on the station's truss will be replaced. - Sophie Adenot will be identified by red stripes on her suit.
What's next
NASA will provide live coverage of the event starting at 7 a.m. EDT.
