MARS COMET: This weekend, Comet Siding Spring (C/2013 A1) will make a historically close approach to Mars.  Satellites and rovers will get an eye-full as the green comet passes less than 140,000 km above the Red Planet's surface. No one knows what will happen. Possible side-effects of the flyby include a Martian meteor shower and auroras.
