Abstract

Map of Jupiter's moon Io The first global geologic map of the Jovian satellite Io has been published by the U.S. Geological Survey (USGS), the agency announced on 19 March. “More than 130 years after the USGS first began producing quality geologic maps here on Earth, it is exciting to have the reach of our science extend across 400 million miles to this volcanically active moon of Jupiter,” said USGS director Marcia McNutt. “Somehow it makes the vast expanse of space seem less forbidding to know that similar geologic processes which have shaped our planet are active elsewhere.” The map illustrates the geologic character of the unique and active volcanoes on Io, a planetary body that has about 25 times more volcanic activity than Earth does, according to USGS.
