Koronas-Foton (
Overview
The goal is to investigate the processes of free energy accumulation in the Sun's atmosphere, accelerated particle phenomena and solar flares, and the correlation between solar activity and magnetic storms on Earth.[8] Launch occurred successfully on 30 January 2009, and the first batch of science data was downloaded from the satellite on 19 February 2009.[9] The satellite operates in a 500 x 500 km x 82.5° polar low Earth orbit[2] and was expected to have an operational lifetime of three years. It developed power system problems during the first eclipse season, about six months after launch, and contact with the satellite was lost on 1 December 2009.[10] The satellite returned to life on December 29, after its solar panels received enough light to power its control systems,[citation needed] but attempts to revive the satellite failed, and the satellite is considered lost.[10][11]
On 5 July 2009, Koronas-Foton's TESIS telescope registered the most powerful solar outburst of the year so far, lasting 11 minutes, from 06:07 to 06:18 GMT. Solar X-ray pick intensity reached С2.7 in a 5-level scale used to classify solar flares. The last equally powerful outburst occurred on 25 March 2008.[12]

Instruments
The satellite's scientific payload includes an array of 12 instruments.[9] Eight instruments were designed for registering electromagnetic radiation from the Sun in a wide range of spectrum from near electromagnetic waves to gamma-radiation, as well as solar neutrons. Two instruments were designed to detect charged particles such as protons and electrons.[9]
