Astronauts Complete Robotic Arm Repairs during Spacewalk


Outside the International Space Station, Expedition 54 Flight Engineers Mark Vande Hei of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency (JAXA) conducted a spacewalk to move a Latching End Effector, or hand, for the Canadarm2 robotic arm into the Quest airlock. The part was removed during another spacewalk last October. They also moved a degraded end effector replaced during a Jan. 23 spacewalk to a long-term storage location on a payload attachment device on the station’s Mobile Base System railcar so it will be available as a spare part. The spacewalk was the 208th in station history for assembly, maintenance and upgrades, the fourth in Vande Hei’s career and the first for Kanai, who became only the fourth Japanese astronaut to walk in space.
