Spotting Spores
Adrian Ponce, deputy manager for JPL’s planetary science section, has devised a new microscope-based method to quickly validate — from days to minutes — a spacecraft’s cleanliness. The method will help in decontaminating spacecraft before launch, and could have medical and pharmaceutical uses on Earth.

Mars Reconnaissance Orbiter Sees Ice Exposed by Meteor Impact
NASA’s Mars Reconnaissance Orbiter has revealed frozen water hiding just below the surface of mid-latitude Mars. The spacecraft’s observations were obtained from orbit after meteorites excavated fresh craters on the Red Planet.
Scientists controlling instruments on the orbiter found bright ice exposed at five Martian sites with new craters that range in depth from approximately half a meter to 2.5 meters (1.5 feet to 8 feet). The craters did not exist in earlier images of the same sites. Some of the craters show a thin layer of bright ice atop darker underlying material. The bright patches darkened...

Space Hand-Me-Downs
Much of the biology on Earth involves molecules that are oriented in a left-handed direction. A proposed nano-satellite would carry up some of these bio-molecules to see if something in space might be responsible for this left-handed excess. The project is part of the Astrobiology Science and Technology Instrument Development and Mission Concept Studies.

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...
