The Greeley Early Career Award is named for pioneering planetary scientist Ronald Greeley. During his lifetime, Ron was involved in nearly every major planetary mission and was extraordinarily active in service to the community. Ron’s greatest legacies, however, are those he mentored, and it is young scientists whose work and promise we seek to recognize. This year’s Greeley award winner is Catherine Neish, an assistant professor at the Florida Institute of Technology. Catherine received her Ph.D. from the University of Arizona in 2008 and, after a postdoctoral stint at NASA Goddard, joined the faculty at Melbourne in the Department of Physics and Space Sciences.
Catherine specializes in planetary surface properties, and she is ecumenical in choice of target, having written papers that incorporate data from eight different planetary bodies: Mercury, Venus, Earth, the Moon, Europa, Ganymede, Titan, and Triton. This certainly embraces the spirit of the Greeley award, as Ron was someone who was interested in the whole of planetary science, not just a single planetary body.
Catherine is expert in the use of orbital radar observations and has used these with optical imaging and topography to thoroughly revise our understanding of impact melt flows. She has also proposed that craters at high latitudes and low elevations on Titan are not simply buried by later sediments but form flattish to begin with, in a manner similar to craters formed on Earth in soft, oceanic sediments.
But not all of Catherine’s work is remote sensing based. Her Ph.D. thesis had three doctor-fathers: Ralph Lorenz, Jonathan Lunine, and Mark Smith. Her papers with them on the astrobiological potential of Titan and the lab work that went into them are notable. The relative ease in which biological molecules such as amino acids can form in ammonia-infused “Titan primordial soup” suggests (as if we needed reminding) that life may be ubiquitous in the universe. One suspects such work will have long-lasting impact.
Congratulations to Catherine D. Neish, the 2014 recipient of the Ronald Greeley Early Career Award in Planetary Science.
