NASA astronauts will venture outside the International Space Station on Tuesday, June 30, to replace a wrist joint on the orbital complex’s Canadarm2 robotic arm. The spacewalk is scheduled to begin at approximately 8:35 a.m. EDT.
Experts from NASA and CSA (Canadian Space Agency) will preview the upcoming spacewalk during a news conference at 2 p.m. on Thursday, June 25, on the agency’s YouTube channel. The briefing will take place at NASA’s Johnson Space Center in Houston. Learn how to watch NASA content through a variety of platforms, including social media.
Participants include:
- Bill Spetch, operations and integration manager, International Space Station Program, NASA Johnson
- Fiona Antkowiak, spacewalk flight director, NASA Johnson
- Jason Dyer, deputy liaison manager, CSA
United States-based media interested in attending in person must contact the Johnson newsroom no later than 5 p.m. Wednesday, June 24, at: [email protected]. Media joining by phone should request dial‑in details by the same deadline. To ask a question, media must dial in no later than 15 minutes before the start of the news conference.

NASA astronauts Chris Williams and Jessica Meir will exit the station’s Quest airlock to replace a wrist joint that malfunctioned during normal Canadarm2 operations on May 27 after the arm drew elevated motor current and did not move as expected.
Watch NASA’s live U.S. spacewalk 95 coverage beginning at 7 a.m. EDT on NASA+, Amazon Prime, Netflix, and the agency’s YouTube channel. The spacewalk is expected to last roughly six-and-a-half hours.
NASA worked alongside CSA to understand the issue and determined a spacewalk was required to replace the joint using a spare already aboard the space station. Repairs to robotics, like Canadarm2, are normal and expected after more than 25 years of continuous operations, as the system was designed with replaceable components and planned maintenance in mind.
This spacewalk will be the second for Williams and the fifth for Meir. Williams will serve as spacewalk crew member 1 and will wear a suit with red stripes. Meir will serve as crew member 2 and will wear an unmarked suit. It will be the 280th spacewalk in support of space station assembly, maintenance, and upgrades.
