MARTIAN METEOR SHOWER: NASA and European spacecraft have detected evidence of a "spectacular" meteor shower on Mars caused by the close approach of Comet Siding Spring last month. If a human had been standing on the Red Planet at the time, they might have seen thousands of meteors per hour followed by a widespread yellow afterglow that lasted for days.
