However, a failure of the Blok DM-2M fourth stage left it stranded in a highly inclined (51.6°) and elliptical orbit, although still fully functional.
[6] Edward Belbruno and Rex Ridenoure heard about the problem and proposed a 3–5 month low-energy transfer trajectory that would swing past the Moon and leave the satellite in geostationary orbit around the Earth.
[6] Although Hughes did not end up using the low-energy transfer trajectory, the insight to use a lunar swingby was key to the spacecraft rescue.
Another lunar fly-by was performed later that month (6 June 1998) at a distance of 34,300 km to further improve the orbital inclination.
[6] Once the satellite was in a stable orbit, it was commanded to release its solar panels, which had been stowed during takeoff and maneuvering.
