Our Space Odyssey concludes with a return to the place we call home. Earth is inhabited by roughly 7 billion human beings with a rich history of trying to eliminate each other. In fact, in the 1959 edition of "interplanetary digest", Earth was voted "The planet most likely to blow itself up". We almost succeeded a few years later. This might be why the Martians, after traveling years to get here, turned around and headed back home. Fun fact: Our DNA may actually have came from Martians - although they don't want to own up to it. But, all kidding aside, a HUGE thanks to everyone who took a few moments to enjoy these images - I enjoyed creating them (and adding my "commentary") - which I hope was fun and unoffensive. So, stay tuned for my next exciting series - which I have absolutely no idea what it is.
