NASA astronauts are taking a spacewalk outside space station today. Here's how to watch live.

Two NASA astronauts will step out into space on a mission to replace a faulty antenna system tomorrow (Dec. 2). The spacewalk was postponed after a space debris alert after accomodating for increased risk following a Russian anti-satellite test that created a debris cloud.

NASA astronauts Thomas Marshburn and Kayla Barron, who recently arrived at the International Space Station aboard SpaceX's Crew Dragon spacecraft as part of the company's Crew-3 mission, will complete a spacewalk together tomorrow. The pair is set to spend about six and a half hours replacing an antenna system on the orbiting lab.
