The British space programme is the British government's work to develop British space capabilities. The objectives of the current civil programme are to "win sustainable economic growth, secure new scientific knowledge and provide benefits to all citizens."

The first official British space programme began in 1952. In 1959, the first satellite programme was started, with the Ariel series of British satellites, built in the United States and the UK and launched using American rockets. The first British satellite, Ariel 1, was launched in 1962. The British space programme has always emphasized uncrewed space research and commercial initiatives. It has never been government policy to create a British astronaut corps. The British government did not provide funding for the International Space Station until 2011.

British space programme

During the 1960s and 1970s, a number of efforts were made to develop a British satellite launch capability. A British rocket named Black Arrow did succeed in placing a single British satellite, Prospero, into orbit from a launch site in Australia in 1971. Prospero remains the only British satellite to be put into orbit using a British vehicle.

British space programme

The British National Space Centre was established in 1985 to co-ordinate British government agencies and other interested bodies in the promotion of British participation in the international market for satellite launches, satellite construction and other space endeavours.

In 2010, many of the various separate sources of space-related funding were combined and allocated to the centre's replacement, the UK Space Agency. Among other projects, the agency is funding a single-stage-to-orbit spaceplane concept called Skylon.

Origins

Scientific interest in space travel existed in the United Kingdom prior to World War II, particularly amongst members of the British Interplanetary Society (founded in 1933) whose members included Sir Arthur C. Clarke, author and conceiver of the geostationary telecommunications satellite, who joined the BIS before World War II.

As with the other post-war space-faring nations, the British government's initial interest in space was primarily military. Early programmes reflected this interest. As with other nations, much of the rocketry knowledge was obtained from captured German scientists who were persuaded to work for the British. The British performed the earliest post-war tests of captured V-2 rockets in Operation Backfire, less than six months after the end of the war in Europe. In 1946 a proposal was made by Ralph A. Smith to fund a British crewed suborbital launch in a modified V-2 called Megaroc; this was, however, rejected by the government.

From 1957, British space astronomy used Skylark suborbital sounding rockets, launched from Woomera, Australia, which at first reached heights of . Development of air-to-surface missiles such as Blue Steel contributed to progress towards launches of larger orbit-capable rockets.

British satellite programmes (1959–present)

Early satellite programmes

The Ariel programme developed six satellites between 1962 and 1979, all of which were launched by NASA.

In 1971, the last Black Arrow (R3) launched Prospero X-3, the only British satellite to be launched using a British rocket, from Australia. Ground contact with Prospero ended in 1996.

Military communications satellite programme

Skynet is a purely military programme, operating a set of communications satellites on behalf of the Ministry of Defence (MoD), to provide communication services to the three branches of the British Armed Forces and to NATO and allied governments. The first satellite was launched in 1969, becoming the first military satellite in geostationary orbit, and the most recent in 2012. As of 2020, seven Skynet satellites are operating and providing coverage of almost the whole globe.

Skynet is the most expensive British space project, although as a military initiative it is not part of the civil space programme. The MoD is currently specifying the Skynet 6 architecture to replace the Skynet 5 model satellites, which is expected to cost about £6 billion.

Intelligence satellite programmes

Zircon was the codename for a British signals intelligence satellite, intended to be launched in 1988, before being cancelled. During the Cold War, the UK's Government Communications Headquarters (GCHQ) was very reliant on America's National Security Agency (NSA) for communications interception from space. GCHQ therefore decided to produce a British-designed-and-built signals intelligence satellite, to be named Zircon, a code-name derived from zirconium silicate, a diamond substitute.
