Unmasking Europa - The Search for Life on Jupiter's Ocean Moon

Professor Richard Greenberg was a 25-year member of the Galileo Imaging Team and is currently a member of a science definition team that is planning a possible NASA flagship mission to Europa. He led a small group of graduate students at the UA's Lunar and Planetary Laboratory in analyzing Galileo's high-resolution views of Europa in the last decade. Galileo showed Europa's surface is anything but smooth. Its surface is covered with vast crisscrossing systems of mountain-sized ridges, jumbled regions of seemingly chaotic terrain and patches that suggest upwellings of new surface materials from below.
