SETI Institute at the 48th LPSC


Charon's cratered uplands at the top are broken by series of canyons, and replaced on the bottom by the rolling plains of the informally named Vulcan Planum.

The 48th Lunar and Planetary Science Conference will be held at The Woodlands Waterway Marriott Hotel and Convention Center,The Woodlands, Texas, March 20–24, 2017.

This conference brings together international specialists in petrology, geochemistry, geophysics, geology, and astronomy to present the latest results of research in planetary science. Several SETI Institute scientists will be there to present and discuss their findings. The long list of abstracts below includes results on the characterization of Mars surface, future missions, instruments to explore the Red Planet, and the study of Mars analog terrains (Iceland, Death Valley and the Atacama desert). The New Horizons flyby data are still being analyzed and several SETI Institute scientists are involved in the mapping of its moon Charon and the understanding of its colorful terrain, informally named named Vulcan Planum.

We hope our scientists will enjoy an excellent conference.
