Abstract: The High Resolution Imaging Science Experiment's (HiRISE) imagery of Mars allows for meter scale identification of surface features. In this imagery we can identify boulders clustering on polygonal patterned ground terrains in polar environments on Mars. Previously, terrestrial analogs of Mars were used to explain boulder clustering. However, the Mars environment is distinct from Earth's and the boulders that cluster on Mars are at least 3 - 10 times larger than any found clustering on terrestrial patterned ground terrains. Here, I propose a new mechanism for boulder clustering unique to Mars and use observations of boulder clustering around impact features to place constraints on the timescale of boulder clustering.
When & Where
The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.
We believe we are conducting the most profound search in human history — to know our beginnings and our place among the stars.
The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach.
Every week the SETI Institute hosts a lecture series that is open to the public, provides free PB&J's and gives people a unique opportunity to interact with some of the world's leading space scientists.
