What's Up for July? Mars is closest to Earth since 2003! If you've been skywatching for 15 years or more, then you'll remember August 2003, when Mars approached closer to Earth than it had for thousands of years. It was a very small percentage closer, but not so much that it was as Mars was an awesome sight: in binoculars, where some large features could be seen, and especially through telescopes. Astronomy clubs everywhere had long lines of people looking through their telescopes at the red planet, and they will again this month!
