Skylark (rocket)

Skylark was a British sounding rocket design. The Skylark was first launched in 1957 from Woomera, Australia and its 441st and final launch took place from Esrange, Sweden on 2 May 2005. Launches had been carried out from sites in Europe, Australia, and South America, with use far beyond the UK by NASA, the European Space Research Organisation (ESRO), and German and Swedish space organizations.

The design first dates to 1955, when initial work was carried out by the Royal Aircraft Establishment at Farnborough and the Rocket Propulsion Establishment at Westcott. The first vehicles were ready less than two years later, and sent for testing to Woomera during the International Geophysical Year.

During the 1960s Skylark evolved into an excellent platform for space astronomy, with its ability to point at the Sun, Moon, or a star. It was used to obtain the first good-quality X-ray images of the solar corona. Within the UK national programme, the frequency of Skylark launches peaked at 20 in 1965 (from Woomera), with 198 flights between 1957 and 1978.

The first X-ray surveys of the sky in the Southern Hemisphere were provided by Skylark launches. It was also used with high precision in September and October 1972 in an effort to locate the optical counterpart of X-ray source GX3+1 by lunar occultation.

Skylarks were built in some numbers into the 1970s, until the UK government decided to end the programme in 1977, thinking that future "low weight" research would be carried out on the Space Shuttle instead. The programme was handed to British Aerospace, who later sold it to Matra Marconi Space, who in 1999 in turn sold it to a small private company, Sounding Rocket Services, based in Bristol.
