The University of Colorado was awarded a $276,806 grant from the National Aeronautics and Space Administration (NASA) to conduct research on biological sulfate reduction and its potential importance for understanding the habitability of Mars, Europa, and Enceladus. The research aims to address uncertainties around the reactivity of sulfate during water-rock reactions and the potential for biological sulfate reduction under different fluid chemistries. The results will help improve the understanding of sulfur cycling and habitability on these planetary bodies. This grant award is not associated with a larger contract vehicle and does not have a set-aside designation. As a public research university, the University of Colorado has extensive expertise in space physics, climate science, and other STEM disciplines, enabling it to support NASA and other federal agencies through research, development, and technology demonstration efforts.
