MVACS Robotic Arm

The primary purpose of the Mars Volatiles and Climate Surveyor (MVACS) Robotic Arm is to support to the other MVACS science instruments by digging trenches in the Martian soil; acquiring and dumping soil samples into the thermal evolved gas analyzer (TEGA); positioning the Soil Temperature Probe (STP) in the soil: positioning the Robotic Arm Air Temperature Sensor (RAATS) at various heights above the surface, and positioning the Robotic Arm Camera (RAC) for taking images of the surface, trench, soil samples, magnetic targets and other objects of scientific interest within its workspace.

An approach to the design of a simple, radiation hard, highly integrated and reliable, lightweight satellite bus

A spacecraft system concept has been developed which uses ion propulsion and a small, simple, lightweight design approach to carry out a focused lunar science mission. The design relies on existing technology to achieve high reliability and the possibility of a near-term launch. Key characteristics of the mission are highly focused objectives, low launch costs, minimization of development risks and design simplicity. The spacecraft for the lunar mission is described with particular emphasis on the design and reliability approaches used. The degree of adaptability of this basic class of spacecraft bus is discussed with particular emphasis on its application as a technology testbed vehicle. Several potential mission applications are reviewed.
