RadioAstron: How a state-of-the-art space telescope works

 

The state-of-the-art Russian orbital radio telescope RadioAstron (Spektr R) is a thousand times more powerful than its foreign counterpart, the Hubble. The unit has high-power solar panels and the world's largest solid-state radar antenna, with a diameter of ten meters. Experts believe that using RadioAstron in conjunction with its land-based counterparts will enable astronomers to see extraterrestrial objects with a resolution of up to seven microseconds.
