NASA astronauts are scheduled to perform a spacewalk today (June 30) to repair the Canadarm2 robotic arm on the International Space Station (ISS). The event will be broadcast live.

The Canadarm2, originally designed for a 15-year lifespan, is now almost twice that age and requires repairs, with another Canadian astronaut slated to assist.

Two NASA astronauts are scheduled to perform a seven-hour spacewalk on June 30 outside the International Space Station. Their mission involves replacing a faulty wrist joint on Canadarm2, a crucial piece of equipment for the station.
