Live coverage is underway as two NASA astronauts prepare for a spacewalk outside the International Space Station. The spacewalk is scheduled to begin at about 8:35 a.m. EDT and last roughly six and a half hours.

NASA astronauts Chris Williams and Jessica Meir will exit the station’s Quest airlock to replace a wrist joint that malfunctioned during normal Canadarm2 operations on May 27 after the arm drew elevated motor current and did not move as expected. NASA worked with CSA to understand the issue and determined a spacewalk was required to replace the joint using a spare already aboard the space station. Repairs to robotics, like Canadarm2, are normal and expected after more than 25 years of continuous operations, as the system was designed with replaceable components and planned maintenance in mind.

Williams will serve as spacewalk crew member 1 and will wear a suit with red stripes. Meir will serve as crew member 2 and will wear an unmarked suit. This spacewalk will be the second for Williams and the fifth for Meir. It also will be the 280th spacewalk in support of space station assembly, maintenance, and upgrades.
