Autonomous Rovers for Mars Exploration

1 Caelum Research Corporation at NASA Ames Research Center 2 University of Washington 3 Carnegie Mellon University ABSTRACT—The Pathfinder mission demonstrated the potential for robotic Mars exploration but at the same time indicated the need for more robust rover autonomy. Future planned missions call for long traverses over unknown terrain, robust navigation and instrument placement, and reli...

Activity Planning for the Mars Exploration Rovers

Operating the Mars Exploration Rovers is a challenging, time-pressured task. Each day, the operations team must generate a new plan describing the rover activities for the next day. These plans must abide by resource limitations, safety rules, and temporal constraints. The objective is to achieve as much science as possible, choosing from a set of observation requests that oversubscribe rover r...

A New Approach to Fitting the Spectra from the Mars Rover Alpha-particle X-ray Spectrometers

A computer code, based upon the existing GUPIX code for PIXE analysis, has been developed to fit X-ray spectra that are excited simultaneously by both XRF and PIXE. Full matrix corrections for both excitation modes are included, and element concentrations are deduced. The code is intended for eventual use in processing spectra from the alpha-particle X-ray spectrometers aboard the Mars Explorat...
