The International Solar Polar Mission (ISPM) is a joint ESA/NASA venture in which two spacecraft, one developed by ESA and the other developed by the Jet Propulsion Laboratory (JPL) acting for NASA, are launched together in February 1983, using the Space Shuttle and the Inertial Upper Stage Rocket. Their trajectories will take them out of the ecliptic plane to regions of space hitherto unexplored on paths that will overfly the poles of the Sun after using Jupiter's high gravity as an accelerating force to throw them out of the ecliptic plane. Two solar polar passes will be made, the mission ending in September 1987 ... The aim of the mission is to make simultaneous studies by both spacecraft of the solar wind and energetic emissions at solar latitudes above 70 degrees where the flow of fields and particles is essentially radial to the Sun and relatively simple in structure.  1, fiche 1, Anglais, - International%20Solar%20Polar%20Mission
