Back on September 22nd, International Space Station’s mission control reported that one of ISS’ robotic arm failed to engage completely. In order to fix the problem, NASA has sent two astronauts to repair the arm.
Although the arm works perfectly for most of the application, it will need to have complete functionality ahead of next months’ supply to ISS. If you are wondering, the arm, named Canadarm-2, is over 55 feet long and weighs in at 4,000 pounds. Operators in the ISS use the arm to safely dock supplies sent to the space station from earth.
This is the second major repair since the arm was delivered to the ISS back in 2001 as back in 2002, the wrist malfunctioned and needed a replacement in orbit. According to Tim Braithwait of the Canadian Space Agency, it’s important that the arm operates perfectly due to its importance for International Space Station. For instance, in addition to the main functionality, it also transmits avionics data, camera feeds as well as other sensor data.
Following this repair, NASA has scheduled for another spacewalk as the space agency plans to replace the LEE-B device since these parts have an expected lifespan of 10 years.
