Complex Orbital Observations Near-Earth of Activity of the Sun, orCORONAS, was a Russian Solar observation satellite programme. Three satellites were launched: CORONAS-I, CORONAS-F, and CORONAS-Photon.
CORONAS-Photon was launched on 30 January 2009, fromPlesetsk Cosmodrome, aboard the final flight of theTsyklon-3 rocket. On 1 December 2009 all scientific instruments on the satellite were turned off due to the problems with power supply that were caused by a design flaw.[4][5] On 18 April 2010 the creators of the satellite announced it was lost "with a good deal of certainty".[6][7]
