Ĭhecked on an insulation cover on a cable connection on the lower Pressurized Mating Adapter (PMA 2) to make sure it is fully installed, attached EVA tools on the side of Unity's upper mating adapter (PMA 1) in preparation for future EVAs, and inspected Orbiter Space Vision System targets on Unity. Installed two box-like antennas on the outside of the Unity module that are part of the S-band early communications system. ISS Expedition spacewalks are separated from shuttle spacewalks by a separator.Ĭonnected computer and electrical cables between the Unity node, the two mating adapters attached to either end of Unity, and the Zarya Functional Cargo Block (FGB). ‡ denotes the one EVA and one IVA performed from the transfer compartment at the forward end of the Zvezda Service Module.Īll other spacewalks were performed from the Quest airlock. † denotes spacewalks performed from the visiting space shuttle's airlock. ^ denotes spacewalks performed from the Poisk module in Russian Orlan suits. * denotes spacewalks performed from the Pirs docking compartment in Russian Orlan suits. Thirty-seven of those spacewalks were performed from a shuttle, ninety-three from the Quest Joint Airlock, thirty-two from the Pirs docking compartment, and two from the transfer compartment at the forward end of the Zvezda service module. Īs of 2 December 2021, there have been 245 spacewalks devoted to assembly and maintenance of the International Space Station totaling 1548 hours and 26 minutes. The total time for that spacewalk was eight hours and fifty-six minutes. Voss conducted a full spacewalk, and then returned to the airlock, but remained in their suits ready to exit the airlock again in case the robotics operations ran into problems. The longest spacewalk was performed on 11 March 2001, when STS-102 crew members Susan J. The spacewalk attached the U.S.-built Unity node to Zarya. The initial spacewalk to begin the assembly of the International Space Station was held on 7 December 1998, following the launch of the first section of the station, Zarya, from Baikonur Cosmodrome, Kazakhstan, on 20 November 1998. From 1998 to 2005, thirty-seven Space Shuttle missions were scheduled to assemble, outfit and begin experiments and research aboard the station. ĭue to the complexity of building a station in space, space agencies train astronauts extensively, preparing them to encounter surprises during spacewalks, teaching them how to assemble special tools and equipment, and carefully coordinating every activity during spacewalks. On the International Space Station (ISS), extravehicular activities are major events in the building and maintaining of the orbital laboratory, and are performed to install new components, re-wire systems, modules, and equipment, and to monitor, install, and retrieve scientific experiments.
