 Martian Volcanic Glass Could Be Hotspot for Life Moffett Field CA (SPX) Apr 27, 2012 - Glass sand on Mars may point the way to chemically-rich water ideal for hosting life. The newly discovered glass dune fields, spread across almost a third of the planet, likely formed from interactions between magma and ice or water - interactions that could create the perfect environments for microbial life. The northern lowlands spread across millions of square miles in the red planet's ... more |

 Russian RESONANCE and Interheliozond projects: linking Sun and Earth Moscow, Russia (Voice of Russia) Apr 25, 2012 - Not nearly as spectacular as astrophysical or planetary missions, magnetospheric studies are nevertheless closer to the Earthling's wellbeing, since plasma environment in the immediate vicinity of the Earth is far greater factor than distant supernovae explosions or methane in the Martian atmosphere. Earth's magnetosphere shields us from space and solar radiation, acting as an interface be ... more |

WSU astrobiologist proposes fleet of probes to seek life on Mars Pullman, WA (SPX) Apr 24, 2012 - A Washington State University astrobiologist is leading a group of 20 scientists in calling for a mission to Mars with "a strong and comprehensive life detection component." At the heart of their proposal is a small fleet of sensor packages that can punch into the Martian soil and run a range of tests for signs of ancient or existing life. They call the mission BOLD. It's both an acronym f ... more |

Asteroid sites hint at life on Mars Edinburgh UK (SPX) Apr 24, 2012 - Craters made by asteroid impacts may be the best place to look for signs of life on other planets, a study suggests. Tiny organisms have been discovered thriving deep underneath a site in the US where an asteroid crashed some 35 million years ago. Scientists believe that the organisms are evidence that such craters provide refuge for microbes, sheltering them from the effects of the changi ... more |
