Sub-glacially erupted volcanoes form free-standing flat-topped mesas, known as tuyas. Although there are some silicic edifices (e.g. Tuffen et al., 2002), most terrestrial sub-ice volcanoes are mafic…

The Valles Marineris is a system of canyons located just south of the Martian equator. The system is about 4000 km long, and, if on earth, would extend all the way across the United States. The…

The surface of Mars has changed dramatically during the three decades spanned by spacecraft exploration. Comparisons of Mars Global Surveyor images with Viking and Mariner 9 pictures suggest that…

Sand dunes are among the most widespread aeolian features present on Mars, serving as unique indicators of the interaction between the atmosphere and surface. On a planetary body, dunes accumulate…

Former USGS scientist, Jeff Johnson, performed key research on the detection of dust on the Martian surface. This work explored the laboratory thermal infrared and visible/near-infrared spectroscopy…

Detailed comparisons of laboratory SO2 spectra with the Cassini observations indicate that a mixture of gases contribute to the equatorial emissions: Potassium (K) is suggested by new detections of…

From NASA Press Release…New data from NASA's Cassini spacecraft reveal topography on Saturn's moon Titan that makes the best case yet for an ice volcano on Titan and reveals the most…

USGS LMMP products will soon be available at the LMMP Portal. These include very large high resolution DTMs and orthomosaics of close to 50 key sites on the lunar surface, and high resolution…
