- Study Reveals Young Mars Was A Wet World
  Posted by Billbar from Space.com
  The most comprehensive study ever conducted of minerals on Mars' surface reveals the planet has undergone three distinct geological eras throughout its history, with water playing a progressively lesser role in each.

- New and Improved Antimatter Spaceship for Mars Missions
  Posted by Billbar from antwrp.gsfc.nasa.gov
  The NASA Institute for Advanced Concepts (NIAC) is funding a team of researchers working on a new design for an antimatter-powered spaceship that avoids this nasty side effect by producing gamma rays with much lower energy. Nuclear powered spacecraft would take astronauts to Mars in about 180 days. "Our advanced designs, like the gas core and the ablative engine concepts, could take astronauts to Mars in half that time, and perhaps even in as little as 45 days," said Kirby Meyer, an engineer with Positronics Research on the study.

- Last minute diversion takes Mars rover to safety
  Posted by Billbar from New Scientist Space
  NASA's Spirit rover has reached safety after weeks of scrambling with low power supplies to reach a place from which to weather the approaching Martian winter. The northern-tilting slope of the spot, dubbed Low Ridge Haven, will help maximise the sunlight reaching the rover's solar panels, ensuring its power stays above the minimum needed.

- Happy Face on Mars Exposed
  Posted by Billbar from Space.com
  With a few hills, some shadow, and a heavy dose of imagination, you can see a lot of things on Earth or in a space rock that are not there. This is called pareidolia. A study last year found that humans are particularly susceptible to seeing human faces where there are none, because our knowledge of the human face is so ingrained in our brains.

- Soggy Sands of Mars?
  Posted by Billbar
  Cracks and fins in the sand in an American desert look very similar to features seen on Mars and may indicate the recent presence of water at the surface. "Recent, as in ongoing now," Dawn Sumner, associate professor of geology at UC Davis, said.

- First Images from Mars Orbiter's High Resolution Camera Wow Researchers
  Posted by Billbar from Space.com
  HiRISE images taken last month will be the camera’s only photos for the next six months. MRO has started to implement "aerobraking" - dipping repeatedly into the upper atmosphere of Mars about five hundred times to scrub off speed and to drop into successively more circular orbits.

- NASA Probe Set for First Dip Through Martian Atmosphere
  Posted by Billbar from Space.com
  NASA’s Mars Reconnaissance Orbiter (MRO) will get its first taste of the Martian atmosphere late Tuesday, dipping through the planet’s wispy outer fringe in the first of hundreds of maneuvers to circularize its orbit.
