The most important thing about the planet Mars is that it contains older rocks than the Earth does due to a lack of a plate tectonic recycling mechanism and lower erosion rates. The ancient crust is better preserved than here on our home planet because of lower thermal and pressure gradients. Therefore, the better preserved and more ancient geologic record of Mars provides invaluable insight into early planetary climate records, habitability and origin of life scenarios, and early geologic processes. Our team in the Planetary Spectroscopy and Mineralogy Laboratory is working many different aspects of martian geology, as well as innovative data processing approaches and important analog studies. In this talk, I will provide some highlights of the team’s work framed within the context of planetary science discovery around the globe. I also hope to describe a bit what the Planetary Spectroscopy and Mineralogy Laboratory can do for you.
