It will 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 in extreme UV, X-ray and gamma rays.

The power problem started in July 2009 during such an eclipse period when the two onboard batteries failed to provide sufficient power. Switching to a backup battery did not improve the situation. As a consequence, the science payload as well as the satellite's heaters shut down about once a month. The intermittent power supply also led to the failure of a sub-unit in the spacecraft's flight control system and the activation of a backup unit.
