NASA astronauts will conduct a spacewalk on Tuesday, June 30, to replace a wrist joint on the International Space Station's (ISS) Canadarm2 robotic arm. The extravehicular activity (EVA) is scheduled to begin at approximately 8:35 a.m. EDT. This maintenance is crucial to ensure the continued functionality of one of the station's most important robotic systems, used for capturing cargo spacecraft, moving equipment, and assisting with external maintenance.

Experts from NASA and the Canadian Space Agency (CSA) will hold a preview news conference to detail the objectives and procedures of the spacewalk. The Canadarm2, a 17.6-meter-long robotic arm, is a fundamental piece of the ISS infrastructure, designed for assembly and maintenance tasks. The wrist joint is an essential component that allows the flexibility and precision necessary for its various operations.
