Interior Channels in Martian Valleys
NASM Scientists Ross Irwin and Bob Craddock and their colleague Alan Howard from the University of Virginia have identified dry river channels within valley networks on Mars. The width of these channels indicates substantial past runoff from Martian drainage basins of up to centimeters per day during wet episodes.

Radar Mapping of the Lunar Poles
The Moon has a small number of areas close to its poles which are never
illuminated. These regions of permanent shadow could trap and retain deposits
of water ice or other frozen volatiles delivered by comet impacts. NASM
scientist Bruce Campbell, working with collaborators at Smithsonian Astrophysical
Observatory, Cornell, and the Arecibo Observatory, collected new radar
maps of the lunar poles using a 70-cm radar wavelength to probe 5 m or
more into the lunar dust. The new maps have a spatial resolution of ~300
m. This research was featured in a recent article in Nature.

Sand Ripples Taller on Mars
Mars has now been found to have sand ripples twice as tall as they would
be on Earth. Initial measurements of some of the Red Planet's dunes and
ripples using stereo-images from the Mars Orbiter Camera onboard the Mars
Global Surveyor have revealed ripple features reaching almost 20 feet
high and dunes towering at 300 feet. Kevin Williams of the Smithsonian
National Air and Space Museum will be presenting this latest insight into
the otherworldly scale of Marscapes on Monday, Nov. 3 at the annual meeting
of the Geological Society of America in Seattle, WA.
