Space Station Astronauts Are Taking a Spacewalk Today Watch It Live

Two Nasa astronauts wrapped up a successful spacewalk on Thursday (Oct 5) to fix the International Space Station's (ISS') ageing robotic arm, the U.S. space agency said.

Thursday's spacewalk was the first of three scheduled spacewalks this month aimed at repairing and maintaining various pieces of equipment outside the ISS, and was the 203rd spacewalk in the history of the space station.

Bresnik and Vande Hei will do the second spacewalk on October 10th to ease the new LEE on Canadarm2, and then replace a camera onto the outside of the station.

In this frame from a computer animation, Bresnik and Vande Hei are shown working to replace the grappling mechanism on one end of the space station's robot arm that has experienced age-related problems. Canadarm2 has two identical Latching End Effectors used to grapple visiting cargo vehicles and payloads, provide data and telemetry to the rest of the Canadian-built Mobile Base System and the unique capability to "walk" from one location on the station's truss to another.

They duo have been assigned to revolve around getting the Canadian robotic arm in good shape for doing work outside ISS. For the third spacewalk, Acaba will join Bresnik instead. While this will be the first-ever spacewalk of the latter, it will mark the third one of Bresnik. The second spacewalk is scheduled for October 10, and the third for October 18.

For identification, Bresnik, call sign EV-1, is using helmet camera 18 and wearing a suit with red stripes.

The problem did not impact ISS operations, but the arm's hand, or Latching End Effector (LEE), needs fix.

The station has a spare LEE stored outside the ISS, which the astronauts retrieved to make the fix. Vande Hei, EV-2, is wearing an unmarked suit and is using helmetcam 20.
