Background - The drivetrain needs for Mars are similar in many respects to advanced propulsion research here on Earth; however, some additional requirements differ significantly from terrestrial applications. The mobile platforms to be deployed on Mars must be able to move in a unique gravity and environment. Therefore, the selection and implementation of powertrain will be critical for mission success.

Approach - The scope of this quick-look project was to investigate the domain of Mars rover research so that SwRI could develop plans for a focused research project. The three main approaches toward developing the research plan include 1) build relationships with NASA, Jet Propulsion Laboratory (JPL), and other Mars contributors; 2) participate in workshops and other technology discussions on Mars Rovers; and 3 develop a business plan that is integrated with NASA programs.

Accomplishments - The project team has made progress in all three approaches. SwRI has developed relationships with technical staff at NASA, JPL, Johnson Space Center, the University of Arizona, and Texas A&M University. Team members have attended the workshop held at SwRI, the Mars Society Annual Conference, the Mars Exploration Program Advisory Group meeting, and the Mars Technology Program Annual Review. A business plan was submitted at the end of October. In summary, the project team has developed a focused research plan, with connections to NASA programs and laboratories currently conducting Mars rover research.
