The physical and chemical nature of the light-toned layered deposits in Terby crater are consistent with deposition of material in a large, standing body of water much earlier in Mars' history.

We are studying the history of landforms on Earth in order to understand how similar landforms were generated on other planets and moons.

Images taken in January 2008 by MESSENGER of Caloris Basin show a complex pattern of deformation unlike that found in any other basin in the solar system.

The search for evidence of ancient lakes on the surface of Mars.

Ground-penetrating radar (GPR) gathers information on subsurface features using radio waves that are transmitted into the subsurface that then reflect off differing layers and structures.

We are studying inverted and volcanic channels using satellite data of Mars and in the field on Earth to better understand how they form.

The Ka'u Desert, located on the western flank of Kilauea Volcano on the main island of Hawaii, may be the best analog to what we think early Mars was like.

The lowlands of Venus are dominated by volcanic lava flows, which have many features similar to ones found on volcanoes on Earth or Mars.

Radar maps of the Moon include stunning views of the polar regions where water ice and other volatiles may accumulate.

We use the world's largest radio telescopes to make radar maps of the Moon.
