Mars Exploration Rover Engineering Cameras

چکیده
[1] NASA’s Mars Exploration Rover (MER) Mission will place a total of 20 cameras (10 per rover) onto the surface of Mars in early 2004. Fourteen of the 20 cameras are designated as engineering cameras and will support the operation of the vehicles on the Martian surface. Images returned from the engineering cameras will also be of significant importance to the scientific community for investigative studies of rock and soil morphology. The Navigation cameras (Navcams, two per rover) are a mast-mounted stereo pair each with a 45 square field of view (FOV) and an angular resolution of 0.82 milliradians per pixel (mrad/pixel). The Hazard Avoidance cameras (Hazcams, four per rover) are a body-mounted, frontand rear-facing set of stereo pairs, each with a 124 square FOV and an angular resolution of 2.1 mrad/pixel. The Descent camera (one per rover), mounted to the lander, has a 45 square FOV and will return images with spatial resolutions of 4 m/pixel. All of the engineering cameras utilize broadband visible filters and 1024 1024 pixel detectors.

The Mars Science Laboratory Engineering Cameras
NASA’s Mars Science Laboratory (MSL) Rover is equipped with a set of 12 engineering cameras. These cameras are build-to-print copies of the Mars Exploration Rover cameras described in Maki et al. (J. Geophys. Res. 108(E12): 8071, 2003). Images returned from the engineering cameras will be used to navigate the rover on the Martian surface, deploy the rover robotic arm, and ingest samples into th...
متن کاملWavelet-Based Image Compression for the Mars Exploration Rovers
In early 2004, the Mars Exploration Rover (MER) mission will land a pair of rovers on Mars and operate each of them for 90 Martian days. Each rover is equipped with an unprecedented nine visible-wavelength cameras: a mast-mounted, high-angular-resolution color imager for science investigations (the panoramic camera, or Pancam); a mastmounted, medium-angular-resolution camera for navigation purp...
متن کاملRover Localization and Landing-Site Mapping Technology for the 2003 Mars Exploration Rover Mission
The technology and experiments planned for rover localization and landing site mapping in the 2003 Mars Exploration Rover (MER) mission are described. We introduce the Mars global and landing site local reference systems. For global rover localization in the Mars body-fixed reference system, a triangulation can be performed using observations of common landmarks on satellite images and the very...
متن کاملConstrained Bundle Adjustment of Panoramic Stereo Images for Mars Landing Site Mapping
In Mars exploration missions, high-precision landing-site topographic information is crucial for engineering operations and the achievement of scientific goals. Detailed topographic information of landing sites is usually provided by ground panoramic images acquired by lander or rover stereo cameras. This technology was employed for the 1997 Mars Pathfinder (MPF) mission and will also be used i...
متن کاملAutonomous Rock Tracking and Acquisition from a Mars Rover
Future Mars exploration missions will perform two types of experiments: science instrument placement for close-up measurement, and sample acquisition for return to Earth. In this paper we describe algorithms we developed for these tasks, and demonstrate them in eld experiments using a self-contained Mars Rover prototype, the Rocky 7 rover. Our algorithms perform visual servoing on an elevation ...
