On 13 Marsh, 2006, NASA’s Cassini spacecraft took this edge-on view of Saturn’s rings, capturing the moon Mimas above the ring plane, illuminated both by the sun and by “saturnshine,” the tiny moon Janus just above the rings and larger Tethys below. Cassini took the photo from a distance of about 2.7 million kilometres (1.7 million miles), combining red, green and blue spectral filters to produce a natural colour view. Cassini’s mission ended 15 September, 2017, when the spacecraft, virtually out of propellant after its long, successful mission, was directed to plunge into Saturn’s atmosphere.
Several recent news stories have reported that a mysterious anomaly in the orbit of NASA’s Cassini spacecraft around Saturn could potentially be explained by the gravitational tug of theorised Planet 9, existing far beyond the orbit of Neptune in our solar system. However, NASA cannot find any unexplained deviations in the spacecraft’s orbit.
