Satellite walls are covered with solar cells that provide 440 watts of electricity including 186 W are used by the scientific instruments.

It also measured the amount of plasma used in the polar regions of the magnetosphere, the flow of the latter in the ionosphere and the entry of other charged particles in it and in the upper atmosphere.

For the first time the entire sequence of events initiated by magnetic substorms to the generation of the aurora was observed in detail.

Analysis of the collected data determined that solar storms deposited such an amount of energy in the ionosphere that it stretched to fill the magnetosphere completely.

Polar instruments were used during the primary mission of the THEMIS satellite between January and April for his study of magnetic tail.
