Meteors are more than just pretty lights in the sky. Since the majority of meteor-producing meteoroids originate from comets, they contain invaluable information about these objects not otherwise obtainable. ... One such possibility is the planet Mars. ... Taking into account the slower average speed of incoming material at the heliocentric distance of Mars from the Sun, a meteoroid of the same mass entering the martian atmosphere at 30km/sec would produce a meteor +0.5 mag fainter than at Earth. ...
