Good news on the Martian front; after making a side trip to study some interesting rocks, the Curiosity Rover has found traces of nitrogenic compounds.  On Earth, nitrogen is usually of organic origins, but on Mars it was probably created by lightning strikes.  Either way, it indicates an increased possibility that Mars may have harbored life at one time, as nitrogen supplies the nutrients for life.
