[U.S. and European astronauts spacewalk to install equipment on the International Space Station] September 2nd, NASA stated on September 1st that two astronauts on the International Space Station completed a nearly 7-hour spacewalk that day to install equipment and carry out maintenance work on the International Space Station. At the same time, they collected external samples of the space station for microbial testing. The two people who emerged from the capsule were NASA astronaut Jessica Meier and European Space Agency astronaut Sophie Adeno. During the spacewalk that lasted 6 hours and 49 minutes, they installed a new retroreflector on the forward port of the International Space Station's "Harmony" node module, which can provide navigation support for spacecraft rendezvous and docking operations. The pair also replaced a high-definition camera on the station's truss and collected samples from the station's exterior to detect microorganisms. In addition, they completed the installation of some power system jumper cables and prepared for later replacement of the Alpha Magnetic Spectrometer radiator.
