Wanted: Easy-Going Martian Roommates
Mars is not for the finicky. If something does live there, it’s likely going to be similar to the more adaptive life forms on our planet. A group of researchers is studying a particular microbe that they think could be a model for Mars life.

Phoenix Results Point to Climate Cycles
The first major peer-reviewed reports on the finding of NASA’s Phoenix Mars Mission have been published in the journal Science. The reports show how favorable chemistry and episodes of liquid water could have made the Phoenix landing site habitable for microbes in Mars’ past. In fact, it is possible that the site could become habitable again in Mars’ future according to Phoenix Principal Investigator, Peter Smith (ASU).Source: [astrobio.net]

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...

Rock Bands Spin an Oxygen Record
The rise of oxygen on early Earth may have been caused by a microbial changing of the guard between methane-producers and oxygen-producers. This swap may have been initiated by a drop in the ocean’s nickel abundance. Continuing studies of the world’s largest iron ore deposits could cement the case.
