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. Due to its small mass and low thrust, the original version of the Skylark had to be launched from a tilting tower to overcome the effects of the wind. Later versions only required a simple trailer.
