Canadarm2's Role and Repair
Canadarm2 is a critical component of the ISS, used for capturing cargo spacecraft, spacewalk support, and station maintenance. The replacement of the wrist joint is part of ongoing efforts to ensure the arm’s continued operation. The spacewalk will be conducted by NASA astronauts, with support from mission control in Houston.
According to the Canadian Space Agency, the repair is essential for maintaining the arm's functionality. The CSA noted that Canadarm2 has been in service since 2001 and has undergone previous repairs and upgrades.
