After one month of mapping the orbit was rotated to a periapsis at
30 degrees north latitude, where it remained for one more month.
This allowed global imaging and altimetry coverage from 60
degrees south to 60 degrees north, over a total of 300 orbits. After
a lunar/Earth transfer and two more Earth flybys, the spacecraft
was to head for Geographos, arriving three months later for a flyby,
with a nominal approach closer than 100 Km. Unfortunately, on
May 7, 1994, after the first Earth transfer orbit, a malfunction
aboard the craft caused one of the attitude control thrusters to fire
for 11 minutes, using up its fuel supply and causing Clementine to
spin at 80 rpm. Under these conditions, the asteroid flyby could
not yield useful results, so the spacecraft was put into a geo-
centric orbit passing through the Van Allen radiation belts to test
the various components on board. The mission ended in June 1994
when the power level onboard dropped to a point where the
telemetry from the spacecraft was no longer intelligible.
