Water on Mars

How many times has NASA discovered water on Mars? For the answer, look in the September 2013 issue, where author Emily Lakdawalla sets the record straight.

Orbiters and landers have returned so many beautiful high-res images, we couldn't include them all in the article. To see more of the photographic evidence for water on Mars, scroll down.
