Topic: JanusWritten by Preston Dyches
Cassini’s wide-angle camera acquired 42 red, green and blue images, covering the planet and its main rings from one end to the other, on September 13th, 2017. Imaging scientists stitched these frames together to make a natural color view. The scene also includes the moons Prometheus, Pandora, Janus, Epimetheus, Mimas and Enceladus. ![]() After more than 13 years at Saturn, and with its fate sealed, NASA’s Cassini spacecraft bid farewell to the Saturnian system by firing the shutters of its wide-angle camera and capturing this last, full mosaic of Saturn and its rings two days before the spacecraft’s dramatic plunge into the planet’s atmosphere.

NASA’s Cassini spacecraft completes first dive into outer edges of Saturn’s RingsWritten by Preston Dyches
Cassini crossed through the plane of Saturn’s rings on December 4th at 5:09am PST (8:09am EST) at a distance of approximately 57,000 miles (91,000 kilometers) above Saturn’s cloud tops. This is the approximate location of a faint, dusty ring produced by the planet’s small moons Janus and Epimetheus, and just 6,800 miles (11,000 kilometers) from the center of Saturn’s F ring. ![]() This graphic shows the closest approaches of Cassini’s final two orbital phases. Ring-grazing orbits are shown in gray (at left); Grand Finale orbits are shown in blue. The orange line shows the spacecraft’s Sept. 2017 final plunge into Saturn.

NASA’s Cassini Spacecraft to begin first phase of it’s end missionWritten by Preston Dyches
Launched in 1997, Cassini has been touring the Saturn system since arriving there in 2004 for an up-close study of the planet, its rings and moons. During its journey, Cassini has made numerous dramatic discoveries, including a global ocean within Enceladus and liquid methane seas on Titan. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Cassini spacecraft sends back images of Saturn’s moons Enceladus, Janus and DioneIcy Moons through Cassini’s EyesWritten by Jia-Rui C. Cook
The encounter was primarily designed for Cassini’s ion and neutral mass spectrometer, which “tasted” the composition of Enceladus’ south polar plume. Other instruments, including the Cassini plasma spectrometer and composite infrared spectrometer, also took measurements. ![]() This raw image from NASA's Cassini spacecraft was taken on March 27th, 2012. The camera was pointing toward Saturn's moon Enceladus at approximately 19,810 miles (31,881 kilometers) away.

Cassini Presents Saturn Moon QuintetWritten by Rosemary Sullivant
From left to right are Janus, Pandora, Enceladus, Mimas and finally Rhea, bisected by the right side of the frame. The view was acquired at a distance of approximately 684,000 miles (1.1 million kilometers) from Rhea and 1.1 million miles (1.8 million kilometers) from Enceladus. ![]() NASA's Cassini spacecraft captures five of Saturn's moons in one image: Janus, Pandora, Enceladus, Mimas and Rhea. This view looks toward the northern, sunlit side of the rings from just above the ringplane. Rhea is closest to Cassini here. The rings are beyond Rhea and Mimas. Enceladus is beyond the rings.
