Scientific paper

An engineering design study of a comet nucleus penetrator system for in situ determinations of comet composition is presented. The system is designed for participation in the Comet Rendezvous/Asteroid Flyby mission to comet Kopff in 1996. The instrumentation payload of the penetrator system will include a passive gamma-ray spectrometer; a high frequency response accelerometer for measurements of the impact deceleration profile of the system as it penetrates to the nucleus of the comet; and several thermocouples mounted along the length of the penetrator to measure temperature and temperature gradients. The mechanical, electrical and thermal interfaces between the penetrator and the Mariner Mark II spacecraft are described. A series of line drawings is provided which illustrates the proposed configuration of the system.
