Flight across Titan

The most detailed images of Ultima Thule — obtained just minutes before the spacecraft's closest approach at 12:33 a.m. EST on Jan. 1, 2019 — have a resolution of about 110 feet (33 meters) per pix...

+ Unannotated Version Like an ancient mariner charting the coastline of an unexplored wilderness, Cassini's repeated encounters with Titan are turning a mysterious world into a more familiar place...

Moon shadows are cast on Saturn's A ring in this image taken almost a month after the planet's August 2009 equinox. Pan (28 kilometers, or 17 miles across) orbits in the Encke Gap of the A ring an...

Prometheus -- lit partly by direct sunlight and partly by saturnshine -- pulls at material in the inner portion of the F ring. Saturnshine is sunlight reflected by the Ringed Planet, which often br...

Saturn's rings occupy the foreground of this image. The small moon Janus appears to hover above, while the far larger moon Rhea is partially obscured by the rings. Janus appears to be located dire...

The Cassini spacecraft's close flyby of Epimetheus in December 2007 returned detailed images of the moon's south polar region. The view shows what might be the remains of a large impact crater co...

At Launch Complex 40 on Cape Canaveral Air Station, the Mobile Service Tower has been retracted away from the Titan IVB/Centaur carrying the Cassini spacecraft and its attached Huygens probe.

Two large craters lie along the boundary between day and night on Saturn's moon Rhea. The bright spots in the middle of each crater may be prominent central peaks. Rhea is 1,528 kilometers (949 mi...

As Titan Turns

This mosaic of Cassini images shows the smallest details ever observed on Saturn's moon Iapetus. Visible here are small craters as well as the base of a large mountain ridge located just south of...

This view from NASA's Cassini spacecraft is the sharpest ever taken of belts of the features called propellers in the middle part of Saturn's A ring. 

This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres at mid-latitudes, from an altitude of 915 miles (1,470 kilometers). The image was taken on Sept. 21, 2015, and h...

This unmagnified view of Saturn's moon Dione shows the moon's bright, wispy terrain, along with several large impact craters. Two of the craters have central peaks. Dione is 1,118 kilometers (695 ...

Bright clouds circumscribe Titan's north polar region -- a frigid land of methane seas. The clouds seen in this image and other recent Cassini spacecraft views are at higher latitudes than similar...

Saturn's moon Daphnis, appearing as a tiny speck in the Keeler Gap of the A ring on the far right of this Cassini spacecraft image, is almost lost among the moon's attendant edge waves. Daphnis (8...

The mobile service tower at SLC-3 is rolled back to reveal the United Launch Alliance (ULA) Atlas-V rocket with the NASA InSight spacecraft onboard.

Saturn's D ring--the innermost of the planet's rings--sports an intriguing structure that appears to be a wavy, or "vertically corrugated," spiral. This continuously changing ring structure provide...

This image from NASA's Dawn spacecraft is dominated by bright rayed craters of different sizes. The most prominent bright rayed crater is named Tuccia.

A scan across Saturn's incredible halo of ice rings yields a study in precision and order. This natural color mosaic was acquired by the Cassini spacecraft as it soared 39 degrees above the unillu...

The Cassini spacecraft spies Titan's south polar vortex from below the moon in this image. Imaging scientists are monitoring the vortex to study its seasonal development. For a color image of the...

NASA's Cassini spacecraft captured this view of Saturn's moon Epimetheus (116 kilometers, or 72 miles across) during a moderately close flyby on Dec. 6, 2015.

Smog Moon November 15, 2004 Full-Res: PIA06520 Smog-enshrouded Titan shows itself to be a featureless orb in this Cassini image taken in v...

On its fourth and final targeted flyby of Rhea, the Cassini spacecraft provided this stunning view of the ancient and heavily cratered surface. Billions of years of impacts have sculpted Rhea's sur...

This poster shows a flattened (Mercator) projection of the Huygens probe's view from 10 kilometers altitude (6 miles). The images that make up this view were taken on Jan. 14, 2005, with the descen...

Iapetus: Light and Dark August 31, 2004 Full-Res: PIA06466 The dark material that coats one hemisphere of Saturn's moon Iapetus is...
