Double lunar swingby and Lissajous trajectory design for the WIND missionTwo alternative mission profiles are presented for the WIND mission whose baseline design includes two years in a double lunar swingby (DLS) orbit followed by one year in a Lissajous orbit about the sun-earth L1 libration point. The first alternative uses a half-month high-inclination transfer orbit between two lunar gravity assists to change the initial sunward DLS orbit to a DLS orbit in the geomagnetic tail region. The second alternative uses a direct insertion from launch into a large-amplitude Lissajous orbit followed by a sunward DLS orbit.
