| Titan's methane: Going, going, soon to be gone? Posted: 15 Apr 2013 01:41 PM PDT By tracking a part of the surface of Saturn's moon Titan over several years, NASA's Cassini mission has found a remarkable longevity to the hydrocarbon lakes on the moon's surface. |
| NASA-funded asteroid tracking sensor passes key test Posted: 15 Apr 2013 01:38 PM PDT An infrared sensor that could improve NASA's future detecting and tracking of asteroids and comets has passed a critical design test. |
| Where are the best windows into Europa's interior? Posted: 15 Apr 2013 09:34 AM PDT The surface of Jupiter's moon Europa exposes material churned up from inside the moon and also material resulting from matter and energy coming from above. If you want to learn about the deep saltwater ocean beneath this unusual world's icy shell -- as many people do who are interested in possible extraterrestrial life -- you might target your investigation of the surface somewhere that has more of the up-from-below stuff and less of the down-from-above stuff. |
| Update: Comet to make close flyby of Red Planet in October 2014 Posted: 15 Apr 2013 09:32 AM PDT New observations of comet C/2013 A1 (Siding Spring) have allowed NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif. to further refine the comet's orbit. |
