New research led by Peter Buhler from the Planetary Science Institute proposes that a carbon-dioxide ice cap may have acted as an insulating layer on Mars, allowing rivers and a large lake to form in the planet’s southern highlands. DEEPS Professor James Head commented, "Peter Buhler has done a magnificent job of exploring the implications of possible massive atmospheric collapse and CO2 ice accumulation in the south circumpolar region at a critical early time in the history of Mars."

The Brown Daily Herald explores the work of two DEEPS labs contributing to NASA’s OSIRIS-REx mission by analyzing specimens returned from a near-Earth asteroid.

Geologists generally think that creep happens on faults that slice through particularly slippery rocks. But a recent study co-authored by Professor Victor Tsai reports that the overall structure of a fault network might also dictate why some faults creep rather than intermittently slip dramatically.
