CURIOSITY IMAGES

Radiation Assessment Detector

This color sketch shows a cross-section of the interior of a small metal box that supports a cylindrical telescope lens on top. Beneath the telescope lens, inside both the telescope housing and the box, are various detectors and circuit boards that will detect and identify energetic particles.

February 16, 2009

About the size of a small toaster, the Radiation Assessment Detector will look skyward and use a stack of silicon detectors and a crystal of cesium iodide to measure galactic cosmic rays and solar particles that pass through the Martian atmosphere.

This view from NASA's Curiosity Mars Rover shows the downwind side of a dune about 13 feet high within the Bagnold Dunes field on Mars. The rover's Navigation Camera took the component images on Dec. 17, 2015. As on Earth, the downwind side of an active sand dune has a steep slope called a slip face.
