Moving Cassini for Testing

Astronaut James B. Irwin, lunar module pilot, works at the Lunar Roving Vehicle during the first Apollo 15 lunar surface extravehicular activity (EVA) at the Hadley-Apennine landing site.

Saturn Storms Observed by Voyager August 5, 2004 Full-Res: PIA01364 Voyager 1 and 2 observed radio signals from lightning which w...

This image from NASA's Dawn spacecraft shows a part of the surface of asteroid Vesta, which is mantled (covered) by an ejecta blanket, evident as smoothly textured surface visible across the image.

During its flight, the Galileo spacecraft returned images of the Earth and Moon. Separate images of the Earth and Moon were combined to generate this view. The Galileo spacecraft took the images in...

This image of domes and fractures in Occator Crater on Ceres was obtained by NASA's Dawn spacecraft on July 3, 2018 from an altitude of about 28 miles (44 kilometers).

Saturn's graceful lanes of orbiting ice -- its iconic rings -- wind their way around the planet to pass beyond the horizon in this view from NASA's Cassini spacecraft

Close-up image of Mars' satellite Deimos from the Viking 2 Orbiter showing craters and associated streaks.

Each of these two montages shows four synthetic views of Titan created using data acquired by the visual and infrared mapping spectrometer (VIMS) on board NASA's Cassini spacecraft between 2004 and...

This composite image, which has become a popular poster, shows a global view of Earth at night, compiled from over 400 satellite images

Spots on Saturn April 2, 2004 Full-Res: PIA05385 As Cassini closes in on Saturn, its view is growing sharper with time and now re...

This interesting vortex in Saturn's atmosphere is surrounded by a halo of bright clouds that extend away toward the east and west. Storms like this one seem to be bright at all wavelengths at which...

Fensal, a magnificent mansion in Norse mythology, is home to Bazaruto Facula and Sinlap on Saturn's largest moon. Two dark bands stretch across the moon Titan in this image: Fensal north of the eq...

Herding the Rings September 21, 2004 Full-Res: PIA06481 Saturn's moon Prometheus is seen shepherding the inner edge of Saturn's F...

The moon Enceladus seems to hover above the outer reaches of Saturn's B ring. Below and to the right of Enceladus, four faint bands lie in the center of the dark Cassini Division. Recently, scient...

This image was taken during Cassini's extremely close encounter with Enceladus on Oct. 9, 2008. The image was taken with the Cassini spacecraft narrow-angle camera on Oct. 9, 2008, a distance of a...

This view of a rock called "Block Island," the largest meteorite yet found on Mars, comes from the panoramic camera (Pancam) on Opportunity.

On January 15, 2001, 17 days after it passed its closest approach to Jupiter, NASA's Cassini spacecraft looked back to see the giant planet as a thinning crescent. This image is a color mosaic ...

Sample of student work from K-4

The Cassini spacecraft captures Janus in the foreground, with Dione in the distance beyond. The image was taken two hours after Hiding Dione, in which Cassini imaged Dione beyond the rings. Janus...

What looks like a pair of Saturnian satellites is actually a trio upon close inspection.

A crescent Saturn appears nestled within encircling rings in this Cassini spacecraft image. Clouds swirl through the atmosphere of the planet. Prometheus (86 kilometers, or 53 miles across) orbits...

Gaseous Saturn rotates quickly -- once every approximately 10.8 hours -- and its horizontal cloud bands rotate at different rates relative to each other.

The rich dynamics of Saturn's F ring are on display in this image taken by the Cassini spacecraft. Most of the features seen here are believed to be due to the ring's interactions with its shepherd...

The Cassini spacecraft looks at an example of a ray crater on the leading hemisphere of Saturn's moon Dione. The ray crater is in the upper-left of the image and ejecta rays show up as brighter ma...

This perspective view of Cairo Sulcus was generated using high resolution images of Enceladus acquired in August 2008 at 12 to 30 meters (40 to 100 feet) resolution, together with a new topographic...
