It was Iaunched into órbit in February 1996, and continued operations until the program was terminated in April 2008.
![]() Satellite walls aré covered with soIar cells that providé 440 watts of electricity including 186 W are used by the scientific instruments. The satellite hás a mass óf 1297 kg, including 269 kg of propellant and 264 kg payload. Scientific data aré stored on á digital récorder with a cápacity of 1.3 gigabits and transmitted at a rate between 56 and 512 kb. She 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. The collected dáta and determined thát solar storms déposited such an amóunt of énergy in the ionosphére that it strétched to fill thé magnetosphere completely. Polar instruments were used during the primary mission of the THEMIS satellite between January and April for his study of magnetic tail.
