Moon not quite round CASSINI PHOTO RELEASE Posted: July 6, 2005
This view shows principally the leading hemisphere on Mimas. Mimas' largest crater, Herschel (130 kilometers, or 80 miles wide), is centered roughly on the equator and can be seen here. North on Mimas is toward upper left. The moon's oblateness is exaggerated by Cassini's viewing angle here -- the Sun-Mimas-spacecraft, or phase, angle was 5 degrees leaving a sliver of the moon's disk in shadow on the northwest limb. The image was taken in visible light with the Cassini spacecraft narrow-angle camera at a distance of approximately 916,000 kilometers (569,000 miles) from Mimas. Resolution in the original image was 5 kilometers (3 miles) per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo. |
