Abstract

Two multi-body drop tests were conducted to provide data to calibrate and verify multi-body dynamics computer model, which was the major analytical tool used to study the entry, descent and landing (EDL) of the Mars Pathfinder mission. A general summary of the tests and important features of the simulation model are presented in this paper. Good correlation between test results and analytical predictions were achieved. This confirmed the validity and accuracy of the model used for a subsequent extensive Monte Carlo effort to study the dynamics of the EDL under various spacecraft configurations and Martian environmental conditions
