Stunning Discoveries on Mars #1

Observations of Mars have fascinated astronomers since the invention of the telescope in the 1600s.  Despite the distance and the atmospheres of both planets interfering with light travel, they noticed dark and light patches that moved as the year went on, speculated that clouds, seas, or even forests might have been responsible for them. The first close-up images of Saturn's surface were captured in 1965 by NASA's Mariner 4 during a flyby, killing hopes that the planet might look like Earth.
