Title:
Stereo Image of Io's Tohil Mons
Creator:
NASA/JPL-Caltech
Description:
This stereo image, which appears three-dimensional when viewed through stereo red-blue glasses, was created from data in images taken on Oct. 11, 1999, and on Feb. 22, 2000, by NASA's Galileo spacecraft of a mountain named Tohil Mons on Jupiter's moon Io. It illustrates the shape of the mountain and two nearby volcanic depressions, which are called paterae. North is toward the top of the image. The largest patera, in the upper right, lies along the northeastern margin of the mountain. The stereo observation reveals that the smaller patera with the dark floor is surrounded by mountainous walls. The black lines are areas where data were not acquired. Information about the red-blue glasses needed for seeing this 3-D image properly is available at http://photojournal… . To the southeast of the peak, many bright lines trending northwest-southeast can be seen. Since the two individual images were taken when the sun was quite high, it was difficult to determine the relationship between the bright material and the topography. The stereo image reveals that the light material is concentrated at the bases of cliffs. This series of cliffs appears step-like, which may indicate layering in Io's crust. By combining several observations in this manner, Galileo scientists are able to study Io's mountains and to learn about their evolution and their relationship to Io's volcanoes. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Galileo mission for NASA's Office of Space Science, Washington, D.C. Images and data received from Galileo are posted on the Galileo mission home page at http://www.jpl.nasa… Background information and educational context for the images can be found at http://www.jpl.nasa… . # # # # #
