“March 28, 2012. This raw image from NASA’s Cassini spacecraft was taken with the camera pointing toward Saturn’s moon Dione at approximately 27,668 miles (44,528 kilometers) away.”

“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 systems everywhere – form and evolve.

On the final orbit, Cassini will plunge into Saturn’s atmosphere, sending back new and unique science to the very end. After losing contact with Earth, the spacecraft will burn up like a meteor, becoming part of the planet itself.

Cassini’s Grand Finale is about so much more than the spacecraft’s final dive into Saturn. That dramatic event is the capstone of six months of daring exploration and scientific discovery. And those six months are the thrilling final chapter in a historic 20-year journey.”

“Saturn’s giant, hazy moon Titan has been essential to NASA’s Cassini mission during its 13 thrilling years of exploration there. Cassini and the European Huygens probe have revealed a fascinating world of lakes and seas, great swaths of dunes, and a complex atmosphere with weather – with intriguing similarities to Earth. Titan has also been an engine for the mission, providing gravity assists that propelled the spacecraft on its adventures around the ringed planet.”

“January 30, 2012. The Cassini spacecraft looks toward the dark side of Saturn’s largest moon and captures the halo-like ring produced by sunlight scattering through the periphery of Titan’s atmosphere. A detached, high-altitude global haze layer encircles Titan. See Titan’s Halo to learn more. This view looks toward the Saturn-facing side of Titan (3,200 miles, or 5,150 kilometers across). North on Titan is up and rotated 29 degrees to the left.

The image was taken in visible green light with the Cassini spacecraft wide-angle camera. The view was obtained at a distance of approximately 123,000 miles (197,000 kilometers) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 162 degrees. Image scale is 7 miles (12 kilometers) per pixel.”

“December 7, 2011. Compared to the gas giant, the two moons shown on either side of Saturn seem particularly small in this Cassini spacecraft view. Tethys (660 miles, or 1,062 kilometers across) is on the right of the image, below the rings. Smaller Enceladus (313 miles, or 504 kilometers across) is on the left of the view, below the rings. Pandora (50 miles, or 81 kilometers across) is also present in this view but is barely visible. It appears as a small grey speck above the rings on the extreme left edge of the image. Pandora has been slightly brightened by a factor 1.2 relative to the rest of the image. This view looks toward the northern, sunlit side of the rings from just above the ringplane.

The image was taken with the Cassini spacecraft wide-angle camera using a spectral filter sensitive to wavelengths of near-infrared light centered at 752 nanometers. The view was obtained at a distance of approximately 1.3 million miles (2.1 million kilometers) from Saturn. Image scale is about 77 miles (124 kilometers) per pixel.”

“November 4, 2011. Saturn’s rings lie between a pair of moons in this Cassini spacecraft view that features Mimas and Prometheus. Mimas (246 miles or 396 kilometers across) is the more noticeable of the two moons and is in the top left of the view. The smaller moon Prometheus (53 miles, or 86 kilometers across) is near the center of the image and is closest to Cassini. Mimas is beyond the rings and farthest from the spacecraft. Lit terrain seen on Mimas is on the leading hemisphere of the moon. This view looks toward the northern, sunlit side of the rings from just above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera. The view was acquired at a distance of approximately 746,000 miles (1.2 million kilometers) from Prometheus and 870,000 miles (1.4 million kilometers) from Mimas. Image scale is 4 miles (7 kilometers) per pixel on Prometheus and 5 miles (8 kilometers) per pixel on Mimas.”

“October 19, 2011. This raw, unprocessed image of Saturn’s moon Enceladus was taken as the spacecraft passed Enceladus, and its infrared instruments, cameras and other instruments monitored activity on the moon, in particular the famed jets erupting from the moon’s south pole. The orbiter flew within about 765 miles (1,230 kilometers) of Enceladus’ surface.”
