The Hills are Colorful in Juventae Chasma

There are many hills about 1 kilometer high in Juventae Chasma, which is located north of the main Valles Marineris canyon system. The floor of the canyon is covered by a sea of sand, but the hills rise above the sand.

A few adventuresome sand dunes have slowly climbed up on the hills, like that near the upper left of the enhanced-color cutout. The color diversity here is exceptional, due to varying mineral compositions and good exposures.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 53.6 centimeters (21.1 inches) per pixel (with 2 x 2 binning); objects on the order of 161 centimeters (63.4 inches) across are resolved.] North is up.

Making Green Fuels, No Fossils Required

Nitrogen-doped carbon nanotubes proved to be efficient, and potentially inexpensive, catalysts for reducing carbon dioxide. Credit: Adapted from Angewandte Chemie Using solar or wind power to produce carbon-based fuels, which are commonly called fossil fuels, might seem like a self-defeating approach to making a greener world. But when the starting material is carbon dioxide, which can be dragged out of the air, the approach is as green as it gets. The technology that makes it economically feasible isn't available yet, but a recently published paper presents nice step forward in the effort to not just sequester CO2, but turn it into a useful fuel that is part of a carbon-neutral future. Xiao-Dong Zhou, an associate professor of chemical engineering at the University of South Carolina, is part of a team that is working on a sustainable approach to harnessing renewable energy. Solar panels and wind turbines are most typically used to produce electricity, bu
