Once upon a time on MARS, Nasa scientists find evidence of flowing water on Mars
Yesterday NASA held a press conference where they announced that after many decades of exploring the planet of MARS, they have found not only evidence of a lot of water having existed on the planet in the far past but that during the current summer months, MARS has active flows of water.
This got me to wondering, just what MARS could have looked like before it lost its surface water due to climate change. Could it have been that it looked just like the wonderful landscapes we still have here on our own planet ?
Was Mars once like the earth ?
