On 18 July 2011 Russia launched Spektr-R from the Baikonur Cosmodrome, Kazakhstan. It is designed to work in tandem with ground-based radio telescopes using a technique called interferometry. Upon reaching space it unfurled a giant radio dish consisting of 27 carbon fibre petals together measuring 10 m across. Part of the international RadioAstron mission, Spektr-R is currently in a highly elliptical orbit ranging from 10,000 km to 350,000 km above Earth.
