first spaceflight on board the ISS for Expedition 60/61/62 in 2019–2020, he spent 45 hours and 48 minutes outside the station. Longest single spacewalk 8 hrs 56 min, by James Voss and Susan Helms, 11 March 2001 on an ISS assembly mission during Shuttle mission STS-102. The space walkers were delayed early in their excursion when a device to help hold an astronaut's feet to the shuttle's robot arm became untethered, and Voss had to retrieve a spare from storage on the exterior of the station's Unity module. After about six hours of work, the pair reentered Space Shuttle Discovery’s airlock. Greatest distance from a spacecraft during a spacewalk All-time (and while on a planetary body): 7.6 kilometers (4.7 miles, 25,029 feet), Apollo 17, Gene Cernan and Harrison Schmitt, EVA-2, December 12, 1972. During their second of three moonwalks, Cernan and Schmitt rode the Lunar Roving Vehicle to geological station 2, Nansen Crater, at the foot of the South Massif. As all spacewalks not occurring on a planetary body (the Moon) have involved short maximum distances from the spacecraft (see below), this remains the furthest distance that humans have traveled away from the safety of a pressurizable spacecraft, during an EVA of any type. Orbital flight: about 100 meters (or 330 feet), Bruce McCandless, STS-41-B, February 7, 1984. With the exception of six Manned Maneuvering Unit (MMU) sorties in 1984 and a test of the Simplified Aid For EVA Rescue (SAFER) in 1994, all other orbital spacewalks have involved a safety tether, anchoring the spacefarer to the spacecraft at a short distance. Among the former untethered spacewalks, Bruce McCandless' first test of the MMU established an orbital EVA distance record from a spacecraft which remained unbroken by later untethered EVAs. Animal records First animals in space The first animals to enter space were fruit flies launched by the United States in 1947 aboard a V-2 rocket to an altitude of . They were also the first animals to safely return from space. Albert II, a rhesus monkey, became the first mammal in space aboard a U.S. V-2 rocket on June 14, 1949, and died on reentry due to a parachute failure. The first dogs in space were launched 22 July 1951 aboard a Soviet R-1V. "Tsygin" and "Dezik" reached a height of and safely parachuted back to Earth. This flight preceded the first American canine space mission by two weeks.
