Newest Earth science mission could extend the accuracy range of weather forecasts, fine-tune flood forecasts.
Ten years after arriving at Saturn, NASA's Cassini spacecraft is still able to send us delightful surprises from a billion miles away. Most recently, it cruised by the large moon Titan and caught a flash of sunlight reflecting off the liquid surface of one of the moon's hydrocarbon seas, Kraken Mare.
A decade ago, NASA's Cassini spacecraft, the largest and most complex robotic probe yet built, arrived in the Saturn system to begin a marathon exploration of the gas giant, its famous and awe-inspiring rings and what has turned out to be a collection of some of the most eye-opening moons in the solar system.
Modern explorers have found a previously unknown ocean -- but this one's on Saturn's moon Enceladus. Learn more from Chabot Space & Science Center's Ben Burress at KQED Science.
If you had to make a choice to shut down either the Mars rover Curiosity or that explorer of the Saturn system Cassini, would you deliver a pink slip to the young, eager, energetic newbie or force an early retirement on a veteran explorer who has delivered volumes of knowledge?
NASA's Curiosity rover on Mars has raised some eyebrows by something it has not detected: methane. And, much farther out, the Cassini spacecraft has made a positive detection of plastic in the atmosphere of Saturn's moon Titan.
On July 19, NASA's Cassini probe captured a picture of the Earth and Moon, offering us a perspective of all of humanity on one tiny dot in space, and a reminder that Cassini is still out there exploring the distant reaches of the Solar System.
