Cassini sees Atlas, Pandora and Janus orbiting Saturn
CASSINI PHOTO RELEASE
Posted: November 17, 2004
Saturn hosts its own miniature solar system, with an entourage of more than 30 moons. This image shows Saturn's A and F rings, along with three of the moons that orbit close to them.
Density waves due to Janus cause some of the bright bands seen in the A ring in this image. Prometheus and Atlas also produce waves in the rings, but their wave regions are too narrow to be seen here. The interactions of the moons with each other and the rings are a major target of study for the Cassini mission.
The planet's shadow stretches all the way across the main rings in this view. The shadow has an oval shape at present, but over the next few years will become more rectangular as the planet orbits the Sun and the angle at which sunlight strikes the rings decreases.
The image was taken with the Cassini spacecraft narrow angle camera on Oct. 6, 2004, at a distance of 6.4 million kilometers (4 million miles) from Saturn through a filter sensitive to wavelengths of visible red light. The image scale is 38 kilometers (24 miles) 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 Cassini-Huygens 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.
Just in time for the Cassini spacecraft's arrival at Saturn, this new poster celebrates the mission to explore the ringed planet and its moons.
