Humans reached outer space mediated in 1944 and have sustained mediated presence since 1958 , [a] as well as having reached space directly for the first time on 12 April 1961 (Yuri Gagarin) and continuously since the year 2000 with the crewed International Space Station (ISS), or since the later 1980s with some few interruptions through crewing ...
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, -radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and meteorology.
U.S. Space Shuttle missions were capable of carrying more humans and cargo than the Russian Soyuz spacecraft, resulting in more U.S. short-term human visits until the Space Shuttle program was discontinued in 2011. Between 2011 and 2020, Soyuz was the sole means of human transport to the ISS, delivering mostly long-term crew.

The International Space Station has the longest period of continuous human presence in space, 2 November 2000 to present (24 years and 92 days). This record was previously held by Mir , from Soyuz TM-8 on 5 September 1989 to the Soyuz TM-29 on 28 August 1999, a span of 3,644 days (almost 10 years).
Humans that leave the familiarity of Earth could morph into a separate species. "These people will become an offshoot of the human tree," Impey said in the interview. "They will probably evolve ...
The Salyut program was the world's first space station program undertaken by the Soviet Union, which consisted of a series of four crewed scientific research space stations and two crewed military reconnaissance space stations over a period of 15 years from 1971 to 1986. Two other Salyut launches failed.
Stephen Hawking is a supporter of space travel, in part, because he thinks the survival of humanity depends on it. Hawking shared these thoughts in an afterword for Julian Guthrie's book "How to ...
