False-color mosaic courtesy of NASA’s Cassini spacecraft shows differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn’s largest moon. Kraken Mare, which is Titan’s largest sea and covers about the same area as Earth’s Caspian Sea and Lake Superior combined, can be seen spreading out with many tendrils on the upper right. The orange areas are thought to be the Titan equivalent of salt flats on Earth. Click image for more info at National Geographic online.

Size does matter in space exploration: smaller might be way better

There are more than one-hundred sizable objects in our solar system with ice or liquid water, each reachable and explorable with present day technology

There are more than one-hundred sizable objects in our solar system, many of them with ice or liquid water, including planets, moons, asteroids, and KBOs, each reachable and explorable with present day technology

Small probes the size of a human hand or smaller could be a big help to planetary exploration. Moore’s Law and tightening budgets could team up to make that technological leap sooner rather than later. In particular, small probes packed with microelectronics and advanced software capable of learning on the alien spot might bring the deep subcyrosphere of moons like Europa or Saturn’s Dionne under scrutiny: [Read more...]

Da Nile ain’t just a river on Titan

(Click image for more info )PASADENA, Calif. – Scientists with NASA’s Cassini mission have spotted what appears to be a miniature, extraterrestrial likeness of Earth’s Nile River: a river valley on Saturn’s moon Titan that stretches more than 200 miles (400 kilometers) from its “headwaters” to a large sea. It is the first time images have revealed a river system this vast and in such high resolution anywhere other than Earth.
