This spacecraft was funded by the German Ministery for Research and Technology (BMFT) and built by the Max-Planck-Institut fuer extraterrestrische Physik, Garching (MPE). It carried: (i) a range of instruments to measure the particles and fields in the plasma environment of near-Earth space (see list below); and (ii) a number of chemical release containers which could be ejected from the spacecraft and then injected to release ion tracers (lithium or barium) into the plasma environment. The spacecraft was spin-stabilised with an axis at initially 0 and later 90 degrees to the ecliptic plane and a period of approximately 4.5 seconds.
