Behind the Book presents Kevin Hand in conversation with Victoria Orphan

Just months after Europa Clipper was launched from the Kennedy Space Center, Behind The Book presents JPL researcher and author Kevin Hand in conversation with Caltech professor Victoria Orphan. Hand's book, Alien Oceans: The Search for Life in the Depths of Space, argues that the notion of the habitable zone should be expanded. At least six moons in the outer solar system are likely to have oceans of water beneath icy facades. Could they support life?

Kevin Hand is a planetary scientist at NASA's Jet Propulsion Laboratory in Pasadena, California, where he directs the Ocean Worlds Lab. His research focuses on the origin, evolution, and distribution of life in the solar system with an emphasis on Jupiter's moon, Europa. From 2011 to 2016 he served as Deputy Chief Scientist for Solar System Exploration at JPL, and from 2015-2023 he was Project Scientist for the NASA's Europa Lander mission concept. He is the Principal Investigator of the SHERLOC spectrometer onboard the Mars Perseverance rover, which is tasked with seeking signs of habitability and past life on Mars. He is also a Co-I on the Europa Clipper mission, and a Co-I on the Titan Dragonfly mission. His work has brought him to the Dry Valleys of Antarctica, the sea ice near the North Pole, the depths of the Earth's oceans, and to the glaciers of Kilimanjaro. Dr. Hand was a scientist onboard James Cameron's 2012 dive to the bottom of the Mariana Trench, and he was part of a 2003 IMAX expedition to hydrothermal vents in the Atlantic and Pacific oceans. He has made nine dives to the bottom of the ocean. In 2011 he was selected as a National Geographic Explorer. His book Alien Oceans: The Search for Life in the Depths of Space, was published in 2020 by Princeton University Press. He was born and raised in Manchester, Vermont.

Victoria J. Orphan is the James Irvine Professor of Environmental Science and Geobiology, and Allen V.C. Davis and Lenabelle Davis Leadership Chair and Director of the Center for Environmental Microbial Interactions.
