Venus Space Mission

In a CNN Wonder article about the NASA Magellan spacecraft’s capture of imagery of Venus in the 1990s, Jennifer Whitten, assistant professor in the Department of Earth and Environmental Sciences, said, “Now that we’re very sure the planet experienced a volcanic eruption only 30 years ago, this is a small preview for the incredible discoveries VERITAS will make.” Whitten is associate deputy principal investigator of VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, And Spectroscopy), a new mission that will head for Venus within a decade.

River channels

José Silvestre, a PhD candidate in the Department of Earth and Environmental Sciences, is part of a team of scientists that analyzed 50 years of satellite imagery to generate the first global database of river avulsions. Avulsions occur when a river abruptly jumps course and forges a new river channel. Silvestre hopes to gain a better understanding of what controls avulsion location in the context of climate and land use changes.
