Seeing Earth From Between Saturn’s Rings, Nearly a Billion Miles Away

The Cassini Orbiter is about 5,000 pounds (minus its fuel, which is all gone, and the Huygens probe it dropped off on Titan in 2004) of science that’s been orbiting Saturn for nearly 13 years. It is, by any objective take, a vanishingly small speck in the vastness of space, and one of the subtle feats of its 12 sensors—including an ultraviolet imaging spectrograph, plasma spectrometer, and cosmic dust analyzer—is reminding…

In ‘grand finale,’ Cassini spacecraft sets off on collision course with Saturn

Cassini and Saturn
The Cassini spacecraft will explore the uncharted territory between Saturn and its rings (shown in this artist’s illustration) before plunging into the planet’s atmosphere in September.

DEEP DIVE

Cassini is bravely going where no spacecraft has gone before — between Saturn and its rings.

The probe, which launched in 1997 and has orbited Saturn since 2004, starts this daring expedition April 22. It will fly through the 2,400-kilometer-wide gap between Saturn and its rings 22 times before plunging into the planet’s atmosphere and burning up on Sept. 15.

Mission scientists designed this dramatic…

Saturn’s Moon Enceladus

In new Cassini portraits, Saturn’s moon Pan looks like pasta

Pan in Cassini image
This week, Cassini captured the closest images ever taken of Pan, a small moon that orbits amid Saturn’s rings.

Saturn serves up the closest thing to space pasta, the latest round of images from NASA’s Cassini probe, released March 9, show.

On March 7, the spacecraft snapped a series of portraits of Pan, Saturn’s small moon that orbits within a 325-kilometer gap in one of the planet’s rings. Taken at a distance of 24,572 kilometers from the moon, these are the closest images of Pan to date.

The close-ups could help refine astronomers’ understanding of the mini moon’s geology and…
