Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and lunar or planetary surface exploration. In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVAs have been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China.

STS-127 was a NASA Space Shuttle mission to the International Space Station (ISS). It was the twenty-third flight of Space ShuttleEndeavour. The primary purpose of the STS-127 mission was to deliver and install the final two components of the Japanese Experiment Module: the Exposed Facility, and the Exposed Section of the Experiment Logistics Module (ELM-ES). When Endeavour docked with the ISS on this mission in July 2009, it set a record for the most humans in space at the same time in the same vehicle, the first time thirteen people have been at the station at the same time. Together they represented all ISS program partners and tied the general record of thirteen people in space with the first such occurrence of 1995.
STS-130 was a NASA Space Shuttle mission to the International Space Station (ISS). Space ShuttleEndeavour's primary payloads were the Tranquility module and the Cupola, a robotic control station with six windows around its sides and another in the center, providing a 360-degree view around the station. Endeavour launched at 04:14 EST on February 8, 2010 and landed at 22:22 EST on February 21, 2010, on runway 15 at the Kennedy Space Center's Shuttle Landing Facility.

Colonel Luca Parmitano is an Italian astronaut in the European Astronaut Corps for the European Space Agency (ESA). He was selected as an ESA astronaut in May 2009. Parmitano is also a Colonel and test pilot for the Italian Air Force. He is the first Italian to command the International Space Station (ISS) during Expedition 61.
Kjell Norwood Lindgren is an American astronaut who was selected in June 2009 as a member of the NASA Astronaut Group 20. He launched to the International Space Station (ISS) as part of Expedition 44/45 on July 22, 2015.
Tyler Nicklaus "Nick" Hague is a United States Space Force colonel and a NASA astronaut of the class of 2013. Selected to be a flight engineer on the International Space Station, his first launch was on Soyuz MS-10, which aborted shortly after take-off on 11 October 2018. His second launch, on 14 March 2019, was successful, taking him and his fellow Soyuz MS-12 crew members to join ISS Expedition 59/60.
Andrew Richard "Drew" Morgan is a NASA astronaut from the class of 2013.
Expedition 61 was the 61st Expedition to the International Space Station, which began on 3 October 2019 with the undocking of the Soyuz MS-12 spacecraft. The Expedition was commanded by ESA astronaut Luca Parmitano, who became the third European and first Italian astronaut to command the ISS. Parmitano, along with his Soyuz MS-13 colleagues Aleksandr Skvortsov and Andrew Morgan, and Christina Koch from Soyuz MS-12, transferred over from Expedition 60. They were joined by Oleg Skripochka and Jessica Meir, who launched on 25 September 2019 on board Soyuz MS-15.
Expedition 63 was the 63rd long duration mission to the International Space Station, which began on 17 April 2020 with the undocking of the Soyuz MS-15 spacecraft and continued until the undocking of the Soyuz MS-16 spacecraft on 21 October 2020, an unusual double-length expedition increment. The expedition initially consisted of American commander Chris Cassidy, as well as Russian flight engineers Anatoli Ivanishin and Ivan Vagner. On 31 May 2020, the Expedition welcomed the crew of Crew Dragon Demo-2, the first crewed flight of SpaceX's Crew Dragon spacecraft, named Endeavour after the eponymous Space Shuttle vehicle. The mission's two crew members Doug Hurley and Bob Behnken undocked from the International Space Station on 1 August 2020 to help bolster research on the station and participate in several spacewalks outside of the station.
Expedition 64 was the 64th long-duration expedition to the International Space Station (ISS) that began on 21 October 2020 with the undocking and departure of Soyuz MS-16. The expedition started with the three crew members who launched onboard Soyuz MS-17 and reached its full complement with the arrival of SpaceX Crew-1, the first operational flight of NASA's Commercial Crew Program (CCP). As Crew-1 consists of a crew of four instead of three like the Soyuz, Expedition 64 marks the beginning of operations for crews of seven on the ISS. In the final week of the mission, Soyuz MS-18 and its three person crew joined the mission. The expedition ended on 17 April 2021 with the departure of Soyuz MS-17.
