And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Scientists discover a fresh impact crater on Mars
Context Camera (CTX) images showed a likely new impact crater formed at this location between July 2010 and May 2012, and now a HiRISE image provides details about this recent impact event.
Our image shows a large, rayed blast zone and far-flung secondary material around an approximately 30 meter-diameter crater, indicating a large explosion threw debris as far as 15 kilometers in distance. Because the terrain where the crater formed is dusty, the fresh crater appears blue in the enhanced color due to the lack of reddish dust.
Good thing it didn't hit anywhere near the Curiosity Rover! 15 miles of "ejecta" suggests it was quite an impact.
