Almost everyone on Earth (except North Americans) can see the eclipse as the sunset-colored shadow of our planet swallows the Moon for almost 2 hours. During totality, the Moon will turn almost the same red color as Mars right beside it--an incredible sight.
Because Mars is opposite the sun, it will rise at sunset and stay up all night long. The best time to look is around midnight when the Moon-Mars pair will be at their highest in the sky. The Red Planet will have no trouble being seen through the glare of the full Moon because Mars itself is so luminous--almost three times brighter than Sirius, the brightest star in the sky.
