ISS Astronauts Go On Spacewalk to Repair Station's Robotic Arm

October 09, 2017

As you get older, some of your joints might get a little crunchy. The same is apparently true of robots. NASA has just sent two astronauts out on a multi-hour spacewalk to repair the International Space Station’s aging Canadian-built robotic arm, part of which broke down in late September. While the arm still works for certain applications, it will need to be fully operational in advance of the station’s upcoming supply drop next month.
