That childhood obsession has evolved. Space and space time are fascinating to me. Our solar system has changed drastically over the course of its life and understanding that past is the largest treasue hunt of them all. Uncovering any hints, or speculations, just make me excited.
NASA posted a great short video to their YouTube page on what Mars might have looked like in the past... enjoy the video and here is their description (found on YouTube):
"Billions of years ago when the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water - a critical ingredient for life. The animation shows how the surface of Mars might have appeared during this ancient clement period, beginning with a flyover of a Martian lake. The artist's concept is based on evidence that Mars was once very different. Rapidly moving clouds suggest the passage of time, and the shift from a warm and wet to a cold and dry climate is shown as the animation progresses. The lakes dry up, while the atmosphere gradually transitions from Earthlike blue skies to the dusty pink and tan hues seen on Mars today."
