Salt Discovered in Saturn's Outermost Ring
For the first time, scientists working on NASA’s Cassini mission have detected sodium salts in ice grains of Saturn’s outermost ring. Detecting salty ice indicates that Saturn’s moon Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water — perhaps an ocean — beneath its surface.
Cassini discovered the water-ice jets in 2005 on Enceladus. These jets expel tiny ice grains and vapor, some of which escape the moon’s gravity and form Saturn’s outermost ring. Cassini’s cosmic dust analyzer has examined the composition of those grains and found salt within...

NASA’s Weird and Wonderful Rovers
NASA’s Mars Exploration Rovers have exceeded all expectations by surviving the rigors of exploring the red planet for five years – well beyond their intended lifespans. The rovers have returned a wealth of important data about Mars, but they’ve also taught NASA engineers important lessons about navigating the surface of an alien world. These lessons have inspired a new generation of weird and wonderful rovers that are capable of climbing, crawling and jumping almost any obstacle NASA can imagine. The technology could prove invaluable in the future exploration of our solar system.

Outer Space Oreos
Scientists have previously exposed organisms and biomolecules to the many rigors of space, but those experiments only managed to take “before” and “after” pictures of their samples. A planned small satellite will monitor on a continuous basis the negative effects of space on biology. The upcoming O/OREOS mission will be the first demonstration flight of the ASTID small payloads initiative.

Planetary Science Decadal Survey
Dear Colleague:
This is the first of what will be a regular series of newsletters to the astrobiology community regarding the 2009-2011 Planetary Science Decadal Survey. We all get too much email, so I’ll try to keep these concise!
The key points in this newsletter are these:
1) The decadal survey will establish the priorities for planetary exploration in the U.S. for the coming decade.
2) Astrobiology is a major crosscutting theme of NASA’s planetary science activities and a central facet of the survey’s scientific scope.
3) The process is just getting started, and will...Source: [National Academies Space Studies Board]
