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.[1]
History
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.[2] Within the UK national programme, the frequency of Skylark launches peaked at 20 in 1965 (from Woomera), with 198 flights between 1957 and 1978.[2]
The first X-ray surveys of the sky in the Southern Hemisphere were provided by Skylark launches.[2] 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.[2]
In 1975, The Federal Republic of Germany through the DFVLR (now German Aerospace Center or DLR) agreed with Australia to launch a Skylark rocket at Woomera for scientific purposes.[3] The launch took place on 14 March 1975. This was followed by three more, launched on 22 February, 13 March 1979,[4] and 24 August 1987.[5][6]
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.
Description
The basic Skylark is 7.6 metres (25 ft) long, 0.44 metres (17 in) in diameter and has a fin span of 0.96 metres (38 in). Booster stages can increase the height to 12.8 metres (42 ft). The original version was propelled by 840 kilograms (1,850 lb) of solid fuel, which enabled 45 kilograms (99 lb) to be launched to an altitude of over 200 kilometres (120 mi). Improvements were made to the engine and the use of a booster increased the payload to 200 kilograms (440 lb) in 1960. Skylark 12, from 1976, could lift 200 kilograms (440 lb) to 575 kilometres (357 mi) altitude.
Due to its small mass and low thrust, the original version of the Skylark had to be launched from a 25 metres (82 ft) tilting tower to overcome the effects of the wind. Later versions only required a simple trailer.
