Development of the Descent Brake Mechanism for the Mars Science Laboratory

This paper describes the design and testing of an electromechanical damper assembly for the Mars Science Laboratory and provides the current program status. Unique test equipment developed for verification of flight requirements is presented. This paper includes the problems that arose during design and testing that are peculiar to a device intended to dissipate energy. The lessons learned relating to assembly and test anomalies and the resulting corrective actions are discussed.
