Lunar Cold Trap Contamination by Landing Vehicles
The emerging interest in lunar mining poses a threat of contamination to pristine craters at the lunar poles, which act as cold traps for water, and may harbor other valuable minerals. Lunar Prospector type missions will be looking for volatile (molecular) compounds that may be masked by the exhaust...
Who's Who: Robotics, Automation & Control
A geologist by training, Carolyn Parcheta had an idea in July of 2013 to develop a robot that explores and measures the shape of volcanic fissures. She worked...

Implementation of a Terrain Radiometric Correction for UAVSAR
A paper discusses a calibration method suited to correct variations of UAVSAR (unmanned aerial vehicle synthetic aperture radar) backscatter with topography. To use radar backscatter to estimate forest biomass on terrain with slopes, it is necessary to remove the effect of topography....

Automatic Lunar Rock Detection and Mapping
Safe spacecraft landing on planetary and small body surfaces is of primary concern. Estimation of landing risk is a critical task when evaluating and certifying potential landing sites. Such analyses require the detection and mapping of all potential landing hazards such as rocks and boulders, craters,...

Sliding Gait for ATHLETE Mobility
ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer) is a multipurpose mobility platform for planetary surfaces. It is a cross between a wheeled rover and a walking robot, and travels using powered wheels mounted on the end of each of six robotic limbs. Each limb is a fully articulated robotic manipulator...
Briefs: Mechanical & Fluid Systems
Future robotic exploration of near- Earth asteroids and the vertical and inverted rock walls of lava caves and cliff faces on Mars and other planetary bodies would require a method of gripping...

Validation of Proposed Metrics for Two-Body Abrasion Scratch Test Analysis Standards
Abrasion of mechanical components and fabrics by soil on Earth is typically minimized by the effects of atmosphere and water. Potentially abrasive particles lose sharp and pointed geometrical features through erosion. In environments where such erosion does not...
