Ariel was a British satellite research programme conducted between the early 1960s and 1980s. Six satellites were launched as part of the programme, starting with the first British satellite, Ariel 1, which was launched on 26 April 1962, and concluding with the launch of Ariel 6 on 2 June 1979. The first four were devoted to studying the ionosphere, the remaining two to X-ray astronomy and cosmic-ray studies.
The programme was conducted by the Science Research Council. The first two spacecraft were constructed by the United States National Aeronautics and Space Administration, with subsequent spacecraft being produced in Britain. All launches were conducted using American rockets; Ariel 1 on a Thor-Delta, and the remainder on Scouts.
