Autonomous Rover Technology for Mars Sample Return
Planetary rovers enable good sample selection and retrieval for Mars sample return missions. After landing, the rovers search for the best possible scientific samples in the region around a lander, and they return these selected samples to an ascent vehicle that launches the samples into Mars orbit. To streamline the search for, the acquisition, and the retrieval of samples, rover autonomy is a...
متن کاملTechnology Development and Testing for Enhanced Mars Rover Sample Return Operations
This paper describes several Jet Propulsion Laboratory research efforts being conducted to support Mars sample return in the coming decade. After describing the 2003/05 mission scenario, we provide an overview of new technologies emerging from three complimentary research efforts: Long Range Science Rover, Sample Return Rover, and FIDO Rover. The results show improvements in planning, navigatio...
متن کاملAutonomous Navigation to Provide Long-distance Surface Traverses for Mars Rover Sample Return Mission
Knowledge acquisition and representation techniques are developed to allow an autonomous vehicle to negotiate a path over partially unknown terrain, such as the long-distance traverses for the Mars Rover Saayle Return Mission. Terrain navigation is accomplished by the following sequence of steps: The skylines from the visibility map and from the space are stochastically matched to update the ve...
متن کاملPlanetary Rover Developments Supporting Mars Exploration, Sample Return and Future Human-Robotic Colonization
We overview our recent research on planetary mobility. Products of this effort include the Field Integrated Design & Operations rover (FIDO), Sample Return Rover (SRR), reconfigurable rover units that function as an All Terrain Explorer (ATE), and a multi-Robot Work Crew of closely cooperating rovers (RWC). FIDO rover is an advanced technology prototype; its design and field testing support NAS...
متن کاملSample Return from “water” Seeps on Mars
Motivation: Some of the most intriguing science discoveries on Mars came from sites that are currently inaccessible for in-situ analysis and sample return. The recent discovery of recurring slope lineae (RSL), such as those observed in Newton crater, are on steep slopes (25° – 40°) that are hundreds of meters down from the crater rim. In-situ analysis and sample capture of out-flow deposits tha...
