Example of student work: final design report on rapid modeling of Mars robotic explorers. The Rapid Modeling of Mars Robotic Explorers project is motivated by the need to evaluate and compare rover architectures and designs for future unmanned Mars missions. The software tool developed by this project can compare costs and benefits over a large space of rover architectures by varying mission science and design parameters. Future missions, including the 2009 Mars Science Laboratory (MSL), can benefit from the trade space analysis provided by this tool.
