The RadioAstron is an international space Very Long Baseline Interferometry project led by the Astro Space Center of Lebedev Physical Institute in Moscow, Russia. The aim of the mission is to use the Spektr-R space telescope to conduct interferometer observations in conjunction with the global ground radio telescope network in order to obtain images, coordinates, motions and evolution of angular structure of different radio emitting objects in the Universe with the extraordinary high angular resolution.
SPEKTR R was lifted into orbit during the mission ‘Zenit-3F | Spektr-R (RadioAstron)’, on board a Zenit 3F space rocket.
The launch took place on July 18, 2011, 2:31 a.m. from 45/1.
