Two companion moons share the sky before the Cassini spacecraft. Tethys is seen
here with one of its two Trojan moons. Calypso, which trails the larger moon in its
orbit by 60 degrees, is a couple of pixels across near lower right. Telesto (not pictured)
is the other Tethys co-orbital moon, leading Tethys by 60 degrees.
For higher resolution Cassini views of Calypso (22 kilometers, or 14 miles across)
and Tethys (1071 kilometers, or 665 miles across), see PIA07633 and PIA07738,
respectively.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera
on Aug. 25, 2007. The view was obtained at a distance of approximately 2.2 million
kilometers (1.4 million miles) from Tethys. Image scale is 13 kilometers (8 miles) per
pixel on Tethys.
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.
