“April 7, 2010. Swinging by Saturn’s small moon Epimetheus, Cassini snapped this shot during the spacecraft’s flyby. Lit terrain seen here is on the Saturn-facing side of Epimetheus (113 kilometers, or 70 miles across). North on Epimetheus is up and rotated 27 degrees to the left.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera. The view was acquired at a distance of approximately 87,000 kilometers (54,000 miles) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 69 degrees. Image scale is 519 meters (1,703 feet) per pixel.”
“After almost 20 years in space, NASA’s Cassini spacecraft begins the final chapter of its remarkable story of exploration: its Grand Finale. Between April and September 2017, Cassini will undertake a daring set of orbits that is, in many ways, like a whole new mission. Following a final close flyby of Saturn’s moon Titan, Cassini will leap over the planet’s icy rings and begin a series of 22 weekly dives between the planet and the rings.
No other mission has ever explored this unique region. What we learn from these final orbits will help to improve our understanding of how giant planets – and planetary ...
