NASA's Dawn is the first spacecraft to orbit two extraterrestrial targets.

What can you see in the February sky? Stars and planets with distinct red and blue colors, like Mars and Sirius.

Final Assembly at the Cape

NASA's Cassini has found salt in Saturn's E ring, hinting that the moon Enceladus could have an underground liquid reservoir, perhaps even an ocean.

Hi, Everyone! My name's Morgan. My favorite topic is Enceladus.

This animation shows the last 30 seconds of Cassini's X- and S-band radio signals as they disappeared from mission control on Sept. 15, 2017.

Take a flight over dwarf planet Ceres in this video made with images from NASA's Dawn spacecraft.

High-Altitude Clouds

On March 6, the Dawn spacecraft will slip into orbit around Ceres, a dwarf planet located in the main asteroid belt.

As the moon Enceladus eclipses its neighbor Mimas, Cassini records a scene possible only around the time of Saturn's approaching equinox.

This video demonstrates the hiss-like radio noise generated by electrons moving along magnetic field lines from the Saturnian moon Enceladus to a glowing patch of ultraviolet light on Saturn.

No one really knew what Vesta looked like until NASA’s Dawn spacecraft decided to drop in on it. Now, images taken by the spacecraft have been stitched together to create a virtual flyover of the j...

In this Voyager Update from the night of the Neptune encounter (25 August 1989), now Voyager Project Manager, Suzy Dodd speaks with such guests as Jay Holberg and Bill Kurth concerning the Voyager ...

This rotating mosaic of asteroid Bennu is composed of 40 images captured by the PolyCam imager onboard NASA’s OSIRIS-REx spacecraft over a four-hour period on Dec. 2, 2018.

This animation illustrates Jupiter's magnetic field.

What might a wet Mars have looked like? This artist's concept attempts to fill in the blanks.

One of the glittering trails caused by small objects punching through Saturn's F ring is highlighted in this movie from NASA's Cassini spacecraft.

This animation re-creates the final descent of ESA's Huygens probe as it landed on Titan on Jan. 14, 2005, after it was dropped off by NASA's Cassini spacecraft.

This movie from Cassini, made possible only as Saturn's north pole emerged from winter darkness, shows new details of a jet stream that follows a hexagon-shaped path and has long puzzled scientists.

While NASA's Cassini spacecraft was pointed to study Saturn's F ring, it happened to catch a globular star cluster passing through the camera's field of view.

On October 15, 1997, the Cassini–Huygens spacecraft was launched on an almost 7-year journey to the Saturn system.

NASA's Dawn spacecraft flys over dwarf planet Ceres which Dawn has been orbiting for mre than a year, providing us with fascinating views of an alien world.

Saturn's two-faced moon tilts and rotates for Cassini in this mesmerizing movie sequence of images acquired during the spacecraft's close encounter with Iapetus on Nov. 12, 2005.

This video describes Cassini measurements of high speed streams of tiny dust particles emanating from the vicinity of Saturn.

This short computer-animated film highlights Cassini's accomplishments and Saturn and reveals the science-packed final orbits between April and September 2017.
