NASA Astronauts Set for 7-Hour Spacewalk to Repair Iconic Canadarm2 on ISS
Two NASA astronauts will conduct a 7-hour spacewalk on June 30, 2026, to repair the International Space Station's Canadian-built robotic arm, Canadarm2, as part of the 95th US spacewalk mission.
A Mission 25 Years in the Making
In April 2001, the Space Shuttle Endeavour’s crew bolted a Canadian-built robotic arm to the International Space Station, knowing that parts would eventually wear out. On June 30, 2026, two NASA astronauts will step outside the ISS for seven hours to perform the first major repair on Canadarm2 since its installation.
What Changed
The spacewalk, designated US Spacewalk 95, aims to replace critical components of the robotic arm that have reached the end of their operational lifespan. The collaboration between NASA and the Canadian Space Agency has been instrumental in analyzing the issue and planning the repair.
Key Points
- Date and Duration: June 30, 2026, for approximately seven hours.
- Mission: First major repair of Canadarm2 since its 2001 installation.
- Collaboration: Joint effort between NASA and the Canadian Space Agency.
- Significance: Part of the 95th US spacewalk mission.
Why It Matters
Canadarm2 is vital for assembling and maintaining the ISS. Its continued operation ensures the station’s ability to support long-term space habitation and future missions, including potential lunar and Mars exploration.
Context and Background
The robotic arm was designed with replaceable parts, acknowledging the inevitable wear and tear of space operations. This spacewalk marks a significant milestone in space maintenance and highlights the international partnership between NASA and the Canadian Space Agency.
What to Watch Next
Follow live updates as the astronauts begin the spacewalk, and stay tuned for post-mission analysis of the repair’s success and its implications for future ISS operations.
