McKinnon, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, says the space science community suffers from an embarrassment of riches when pondering which of Jupiter’s moons should be studied next, because they all differ in the way that they can reveal more about planets and how they behave. But he thinks it is Europa that clearly commands the most attention.
