Crazy Engineering: Ion Propulsion for the Dawn Mission

Part of the shadow of Saturn's moon Mimas appears as if it has been woven through the planet's rings in this unusual series of images from Cassini.

What's Up for April? Morning planets, a sunset arch, and finding Leo the lion...

What can you see in the April sky? The Moon visits Mars in the evening, and later joins Saturn and Jupiter for a spot of tea. Also, how to find Polaris, the North Star.

On Earth, the ocean floor is home to hydrothermal vents that spout hot water, nourishing life in an otherwise inhospitable environment. Scientists think similar vents could exist on other worlds.

Glowing like a neon lasso, Saturn’s aurora is seen spinning above Saturn’s north pole over the course of most of a Saturn day in this movie made from multiple images taken by the ultraviolet imagin...

This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and ...

Look for the charioteer constellation, Auriga, along with two easy-to-locate star clusters, M41 and M47. And watch as Jupiter and Venus get close.

This still from a movie shows an image taken by NASA's Dawn spacecraft layered on a digital terrain model of an unusual hill containing a dark-rayed impact crater and nearby dark deposit on asteroi...

This animation illustrates Jupiter's magnetic field.

What's Up for November? Mercury transits across the Sun, and the dimming of the "Demon star," Algol.

  Take a virtual ride with Voyager 1 and 2 past Jupiter, Saturn, Uranus and Neptune.

This movie created from images obtained by NASA’s Cassini spacecraft shows a propeller-shaped structure created by a hidden, embedded moon moving through one of Saturn's rings.

This movie captured by NASA'S Cassini spacecraft shows a south polar vortex, or a swirling mass of gas around the pole in the atmosphere, at Saturn’s moon Titan.

The most prominent jets of vapor and icy particles emerging from the south polar terrain of Saturn’s moon Enceladus are shown here in graphical form in a movie clip of a “rotating” Enceladus.

Like boot prints on the Moon, NASA's OSIRIS-REx spacecraft left its mark on asteroid Bennu. Now, new images — taken during the spacecraft's final fly-over on April 7, 2021 — reveal the aftermath of...

Six years of exploration through the 'eyes' of the Mars Exploration Rover Spirit.

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

Explore. Create. Share. How has Cassini inspired you?
