Sols 2574-2576: Characterizing Central Butte

In today’s plan, Curiosity is still investigating Central Butte. The rover is a little further up the side of the butte, and the goal is to characterize the different units that we can observe. The Navcam image displayed above shows the workspace (the area right in front of the rover that the arm can reach) for our weekend plan.

How to create a quality digital terrain model

A digital terrain model (DTM) is a digital representation of the elevation of a planetary surface. Members of the Astrogeology team produce DTMs of different bodies in the solar system to address questions about how landscapes formed or changed over time, and to identify safe landing sites for robotic missions.

Walk in the footsteps of the Apollo astronauts: A field guide to northern Arizona astronaut training sites

Every astronaut who walked on the Moon trained in Flagstaff, AZ. In the early 1960s, scientists at the newly formed United States Geological Survey (USGS) Branch of Astrogeology led this training, teaching geologic principals and field techniques to the astronaut crews. USGS scientists and engineers also developed and tested scientific...

Active boulder movement at high Martian latitudes

Lobate stony landforms occur on steep slopes at high latitudes on Mars. We demonstrate active boulder movement at seven such sites. Sub-meter-scale boulders frequently move distances of a few meters. The movement is concentrated in the vicinity of the lobate landforms but also occurs on other slopes. This provides evidence for a new, common style...
