The Aristoteles mission requires a near polar, circular orbit at low altitude. In years of preparatory studies, a complex mission profile has evolved, including altitude and inclination change maneuvers, as well as month long orbit maintenance at selected attitudes. The baseline mission profile adopted in the current system definition study is described. The main features of the mission are discussed and a rationale for the selected orbit parameters is given. Given the very low altitude at which the satellite is to fly in the gravity part of its mission, minimization of drag is identified as being of paramount importance. The mission is tailored to take place around minimum of the eleven year cycle of solar activity. This requires a launch in 1997 to 1998. A later launch date would demand substantial modification of mission design.
