Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
During the 1970s, the Soviet Union directed its energies to human habitation of space stations of increasingly long durations.
Following their first mission of détente on the 1975 Apollo-Soyuz Test Project, the Soviet Union and the United States again collaborated with each other on the Shuttle-Mir initiative, efforts which led to the International Space Station (ISS), which has been continuously inhabited by humans for over 20 years.
As of 2025, the uncrewed probe Voyager 1 is the most distant artificial object from the Earth, part of a small class of vehicles that are leaving the Solar System.
He broke the record of Gennady Padalka on 4 February 2024 at 07:30:08 UTC during his fifth spaceflight aboard Soyuz MS-24/25 for a one year long-duration mission on the ISS.
[14] The International Space Station has been continuously occupied by a Russian and US crew member since 2 November 2000 (24 years, 102 days).
Eugene Cernan and Harrison Schmitt of the Apollo 17 mission stayed for 74 hours 59 minutes and 40 seconds (over 3 days) on the lunar surface after they landed on 11 December 1972.
As Apollo commanders were the first to leave the LM and the last to get back in, Cernan's EVA time was slightly longer.
[40] Polaris Dawn crew Jared Isaacman, Scott Poteet, Sarah Gillis and Anna Menon fired their Crew Dragon Resilience's Draco thrusters on 11 September 2024 at 00:27 UTC, at 15 hours and 4 minutes after liftoff and achieved a record apogee altitude of 874.95 miles (1,408.10 km).
[14] The record for uncrewed spacecraft is held by the Parker Solar Probe at 191.7 km/s, about 1/1600 (or 0.064%) the speed of light, relative to the Sun.
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 68 miles (109 km).
[57] 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.
[59] Soviet space dogs Veterok (Ветерок, "Light Wind") and Ugolyok (Уголёк, "Ember") were launched on 22 February 1966 on board Cosmos 110 and spent 22 days in orbit before landing on 16 March.
