High in the Arctic, just below Earth's north polar ice cap, biologists, geologists, and engineers come together in Svalbard every August to practice and prepare for an expedition to Mars.
Planetary Surface Processes Field Trip: Day 6
Grand Falls and Sand Dunes
Posted by Ryan Anderson on 2009/03/20 04:35 CDT
Today we visited Grand Falls and the nearby dune field. Grand Falls is especially interesting because it combines many of the processes that are active in shaping planetary surfaces.

One of the ways that planetary scientists try to understand the origin and evolution of landforms on other planets is by studying similar kinds of landforms or "analogs" here on the Earth. For the past few days I've been working with a group of colleagues doing just that--specifically, studying dunes in the Great Sand Dunes National Park and Preserve in order to try to better understand the nature of sand dunes on Mars.

As MESSENGER began its approach for its August 2 flyby of Earth, its cameras have snapped their first images. The images clearly show a cloudy Earth—and, to scientists' surprise, the Moon as well.
