Summary
Spektr-R (RadioAstron) launched on a Russian Federal Space Agency (ROSCOSMOS) Zenit from 45/1, Baikonur Cosmodrome, Republic of Kazakhstan on July 18, 2011 at 02:31 UTC. It was Russian Federal Space Agency (ROSCOSMOS)'s 206th launch, 7th this year and humanity's 5,144th orbital launch attempt. It was the 2nd Zenit flight. The payload was bound for Elliptical Orbit (Elliptical). Spektr-R, one of 355 catalogued objects, reached a 1,052 × 332,735 km orbit inclined 51.6°. 355 objects from this launch are catalogued, one of them a payload.

About this launch
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.
