Two Astronauts will go outside the International Space Station to Repair Space Station’s Robotic Arm

NASA astronauts Randy Bresnik and Mark Vande Hei will go outside the International Space Station (ISS) for the two spacewalk. The first spacewalk will focus on repairing the orbiting lab’s main robotic appendage, the Canadian robotic arm because its latching end effectors are not working properly.

The spacewalk will be the first out of their three planned for October that having the aim to get the Canadian robotic arm in good shape for doing effective work outside the ISS.

Canadarm2, the Canadian robotic arm is one of the essential tools on the ISS. The skillful instrument can extend up to closely 60 feet into space and grab onto large objects. In the early 2000s, Canadarm2 was used to help move and install large pieces of equipment. And now, it is used in performing the inspection on the outside of the ISS and grab and dock incoming cargo spacecraft.

It was launched in 2001, after that it’s starting to encounter several deterioration. It’s two Latching End Effectors, or LEEs, have been worsening. One LEE is connected to the ISS by attaching the arm to the station; the other is extended into space and grabs the objects. They are complex devices which integrate a camera, sensors, and electronics.

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. Then last that means, the in third spacewalk NASA astronaut Joe Acaba will join Bresnik on October 15th to perform more changes and another camera replacement.
