Seeing the Invisible Colors of Mars - SpaceDaily  The Pancam on Spirit and Opportunity records these colors in spectral images. The Mini-Thermal Emission Spectrometer (Mini-TES) is another spectrometer on the Mars Exploration Rovers (MER) and measures infrared radiation. Our eyes cannot "see" the infrared radiation, but the spectrometer can. Rocks are composed of minerals and each mineral has a certain spectrum that can be measured by the spectrometer.  
Depth To Bedrock, Zero - SpaceDaily  Left:  This high-resolution image captured by the Mars Exploration Rover Opportunity's panoramic camera highlights the puzzling rock outcropping that scientists are eagerly planning to investigate. Presently, Opportunity is on its lander facing northeast; the outcropping lies to the northwest. These layered rocks measure only 10 centimeters (4 inches) tall and are thought to be either volcanic ash deposits or sediments carried by water or wind. Data from the panoramic camera's near-infrared, blue and green filters were combined to create this approximate, true-color image. Image Credit: NASA/JPL/Cornell  ). The rover will look at the fine soil nearby, in hopes of finding out why this particular region is rare on Mars in being rich with iron-oxides. The surface soil's top layer is grey, much more grey than anything seen on Mars before. But this dark layer gave way when the airbags were retracted revealing a deep maroon layer underneath.

Follow The Fire And Land On A Martian Volcano - SpaceDaily  The current generation of Mars missions has adopted the theme, "Follow the Water", as a quest to understand the complex geological history of a planet that may have had significant reserves once. For that much warmer and wetter Mars, this motto also requires other ingredients for microbial life, including primordial "fire" in the form of biological temperature ranges. The surface temperature averages -64 F (-53 C), but varies between 200 below zero during polar nights to 80 F (27 C) at midday peaks near the equator. Such temperature extremes suggest that to realize a locally warmer Mars today may require extra heat, such as near a geothermal source.
