When we make it to Mars, there’s an excellent chance that we will find a vast, easy-access watering hole to help sustain life on the Red Planet. This ice-crusted reservoir was found by Nadine Barlow, director of UCF’s Robinson Observatory, and her partners John Koroshetz, a former UCF physics undergraduate student, and James Dohm, a research associate with the University of Arizona’s Department of Hydrology and Water Resources. Barlow’s use of impact craters to identify a near-surface ice reservoir south of the big canyon system Valles Marineris on Mars is outlined in the August 15 issue of Geophysical Research Letters.
