The Clementine ISAS consisted of a Thiokol Star 37FM solid rocket motor attached to an interstage adapter structure. The adapter was cylindrical and was wrapped with solar panels. The small instrument pallet with a mass of about 5 kg was attached to the inside adapter wall above the rocket motor. A simple transceiver system allowed communications with Earth. The adapter was spin-stabilized during the booster burn, but had no attitude control or determination.
The ISAS was equipped with three experiments which were also flown on
the Clementine lunar orbiter. These were a radiation monitor, an instrument
to determine damage coefficients of radiation-hard and -soft complemetary
metal-oxide-semiconductor devices, and a dosimeter. Studies were also done
on the radiation effects of types of devices flown on ISAS, including a
linear charged coupled device (LCCD), an electrically erasable programmable
read-only memory device (EEPROM), a field-programmable gate array (FPGA),
and a static random access memory device (SRAM). Performance and calibration
measurements were made of these devices throughout the flight to ascertain
the effects of radiation. An orbiting meteorite and debris counter (OMDC)
consisted of impact detectors which provided data on natural meteoroids
and man-made debris in the near-Earth environment. Performance of other
spacecraft systems was also monitored.
