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 Remembered http://www.astrobio.net/news/article1311.html This 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 Earth http://www.astrobio.net/news/article1310.html How 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-Style http://www.astrobio.net/news/article1309.html One of the mysteries in paleontology is how extraordinary preservation happens and 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.
