The impact will excavate a crater of approximately 100 meters in diameter and 25 meters in depth. Dramatic images from both the flyby spacecraft and the impactor will be sent back to distant Earth in near-real time. Saturn's Lightning Bolts Shocking http://www.astrobio.net/news/article1355.html As hard as it might be to imagine a lightning bolt a million times stronger than on Earth, Saturn offers such enormous storms. The approaching Cassini spacecraft detected disruption of its radio signals nearly 100 million miles from the planet, and the source has been linked to such astonishing storm systems on the turbulent planet. Jack Frost Hits Mars http://www.astrobio.net/news/article1354.html As the evidence for past martian water becomes stronger, what can be said about the hydrology today on the red planet? Looking for images showing weather on Mars requires some patience, but one may have to look no further than the rovers themselves to see what a cold, martian morning might bring. Titan: Peeling the Onion http://www.astrobio.net/news/article1353.html The mystery of Titan's atmosphere has to do not only with its methane-rich smog, but also with its comparable pressure to Earth. Often called the Earth-like moon, Titan shows finely layered boundaries as the smog dissipates into space.
