On a high-inclination orbit of Saturn, the Cassini spacecraft gazes down at the north polar region of Janus.
This view looks toward Janus (179 kilometers, or 111 miles across) from a perspective 72 degrees north of the moon's equator. The image was taken with the Cassini spacecraft narrow-angle camera on July 14, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers. The view was acquired at a distance of approximately 259,000 kilometers (161,000 miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 78 degrees. Image scale is 2 kilometers (5,085 feet) per pixel.
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 operations center is based at the Space Science Institute in Boulder, Colo.
