Orbit

STORM employs a single lunar swing by to enter a circular 90° inclination orbit with a radius of 30 Earth radii and a period of 9.65 days which precesses a full 360° per year. This orbit enables observations of the magnetosphere’s response to varying solar wind conditions from the full range of vantage points over time scales encompassing all space weather phenomena. Furthermore, this orbit allows scientific return 100% of the time from at least a single instrument and up to 83% of the time from all instruments, allowing for extended observation periods.
