Apollo was the third human spaceflight program undertaken by NASA, the space agency of the United States. It used Apollo spacecraft and Saturn launch vehicles, which were later used for the Skylab program and the joint American-Soviet Apollo-Soyuz Test Project. These later programs are thus often considered to be part of the overall Apollo program.
Human spaceflight programs have been conducted by the Soviet Union–Russian Federation, the United States, Mainland China, and by American private spaceflight companies. Graphs are unavailable due to technical issues.
Space programs of the United States date to the start of the Space Age in the late 1940s and early 1950s. Programs involve both crewed systems and uncrewed satellites, probes and platforms to meet diverse program objectives. From a definition perspective, the criteria for what constitutes spaceflight vary.
Human spaceflight is distinguished from spaceflight generally, which entails both crewed and uncrewed spacecraft. There are two definitions of spaceflight. The Fédération Aéronautique Internationale (FAI), an international record-keeping body, defines the boundary between Earth's atmosphere and outer space at 100 kilometres (62 mi) above sea ...
The Indian Human Spaceflight program (or the Gaganyaan program) is an ongoing programme by the Indian Space Research Organisation (ISRO) to develop the technology needed to launch crewed orbital spacecraft into low Earth orbit. [4]
The "Review of United States Human Space Flight Plans" was to examine ongoing and planned National Aeronautics and Space Administration development activities, as well as potential alternatives and present options for advancing a safe, innovative, affordable, and sustainable human space flight program in the years following Space Shuttle ...
Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. An early highlight of the Space Race, its goal was to put a man into Earth orbit and return him safely, ideally before the Soviet Union.
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.
