Ariel 2, also known as UK-C, was a British radio astronomy satellite, which was operated by the Science and Engineering Research Council as part of the Ariel programme.[2] It was built in America by Westinghouse Electric,[3] and had a mass at launch of 68 kilograms (150 lb).[4][5] It was launched in 1964, and became the first satellite to be used for radio astronomy, although the Canadian satellite Alouette 1 was launched 1962 and also did similar radio astronomy observations.
