Saturn has overtaken Jupiter as the solar system's satellite king. Astronomers just discovered 20 previously unknown Saturn moons, boosting the ringed planet's tally of known satellites to 82 — three more than Jupiter. And there's more exciting news: You can help name these newfound objects.
When NASA’s new drone Dragonfly arrives on Titan, Saturn’s largest moon, it won’t roll across the surface like Curiosity, Spirit, and Opportunity have on Mars. Instead, Dragonfly is a dual-rotor quadcopter that will fly from point to point, using a vertical takeoff and landing (VTOL) system. It leverages existing drone technology we have on Earth to make the system work.
NASA and the European Space Agency unveiled the new Saturn portrait today (Sept. 12). The image was taken on June 20 by Hubble's Wide Field Camera 3 as Saturn was about 845 million miles (1.36 billion kilometers) away. It's the second in a series of annual photos for the Outer Planets Legacy project by scientists studying the gas giant planets of our solar system.
Most of what we know about Saturn’s moon Titan comes from the Cassini probe, which studied it repeatedly during its 13-year mission orbiting Saturn. Cassini is gone, but Titan is going to get another robotic visitor in the coming years. NASA has given the green light to the Dragonfly mission, a project to send a multi-rotor flying vehicle to the surface of Titan. This mission is on track to make history in more ways than one.
The final chapter in a remarkable mission of exploration and discovery, Cassini's Grand Finale is in many ways like a brand new mission. Twenty-two times, NASA's Cassini spacecraft will dive through the unexplored space between Saturn and its rings. What we learn from these ultra-close passes over the planet could be some of the most exciting revelations ever returned by the long-lived spacecraft. This animated video tells the story of Cassini's final, daring assignment and looks back at what the mission has accomplished.
A pockmarked, icy landscape looms beneath NASA's Cassini spacecraft in new images of Saturn's moon Dione taken during the mission's last close approach to the small, icy world. Two of the new images show the surface of Dione at the best resolution ever.
Cassini passed 295 miles (474 kilometers) above Dione's surface at 11:33 a.m. PDT (2:33 p.m. EDT) on Aug. 17.
