spacetoday.net: Astronauts complete fourth ISS spacewalk in a month

Astronauts conducted the fourth spacewalk outside the ISS in less than a month Tuesday. NASA astronaut Jessica Meir and ESA astronaut Sophie Adenot spent six hours and 49 minutes outside the station conducting several maintenance tasks. That work included installing a new retroflector, used as a docking aid, on the port on the Harmony module, as well as replacing a high-definition camera and swabbing an area of the station's exterior to study any microorganisms there. The two also partially completed work installing jumper cables for electrical systems and preparing future work to replace the radiator on the Alpha Magnetic Spectrometer instrument. NASA deferred the completion of that work and other tasks when Adenot reported a problem with a shoulder joint in her suit, apparently caused by cabling getting caught in the joint.
