Clementine (AKA Deep Space
Probe Science Experiment). The Clementine spacecraft was a BMDO/NRL sponsored
program that tested lightweight BMDO sensor technology while gathering
science data. The Clementine vehicle was launched in February of 1994.
After orbiting the Earth for a brief period, the Clementine vehicle was
sent on a trajectory that took it to the moon, where it entered a lunar
orbit. The probe was in lunar orbit for several months and returned more
than 1.5 million images detailing lunar soil mineral composition. The Clementine
mission achieved all mission objectives with the exception of the asteroid
intercept. See the Clementine Press Release
for more information. The SCL system is used on-board
the DSPSE to perform TT&C functions, system health and welfare monitoring
and anomaly resolution. The mission requires a high degree of autonomy
and makes extensive use of SCL's command and control capabilities. The
Clementine flight processor is the MIL-STD-1750A and uses the Ada version
of the SCL Real-Time Engine. SCL was also used on the ground system to
develop mission tasking loads and interface with the existing ground control
system.
