Big Planet, Tiny Vehicleshttp://www.astrobio.net/news/article1312.htmlWhat
can the Mars rovers do after reaching Endurance Crater and the Columbia Hills.
Principal investigator Steve Squyres talked with Astrobiology Magazine what's
next: Can Opportunity drive five more kilometers to Victoria Crater, while being
commanded by dedicated graduate students? He introduces two tiny vehicles to a
big planet where the work is never done.Apollo 12 Rememberedhttp://www.astrobio.net/news/article1311.htmlThis
last week marked the thirty-fifth anniversary of the precision landing for
Apollo 12. The mission sought to retrieve a camera casing from the robotic
Surveyor 3 which had survived three years on the surface. But did biology sneak
into their equation? The debate is examined with fresh historical
perspective.The Breathable Earthhttp://www.astrobio.net/news/article1310.htmlHow
did Earth achieve an atmosphere that is oxygen-rich and breathable, while Mars
and Venus couldn't? One answer is that deeper, mantle volcanoes started bringing
up water vapor and carbon dioxide, instead of hydrogen and carbon
monoxide.Soft-Shelled Crab, Fossil-Stylehttp://www.astrobio.net/news/article1309.htmlOne

whether a soft-shelled animal can be studied in the fossil record. One instance
of this that seems plausible is the decayed carcass that gets consumed by
bacteria, which then encase and preserve the earliest animals.Monday,
