Past 10 years ago this week, news from Mars made a vast splash on Earth — water may still stream on the surface of the red planet. That information, announced by NASA, hinged on photos of brand new gullies imprinted across the Martian surface, and a decade of other water-on-Mars discoveries result. Until now even 10 years later ultimate evidence of flowing Mars water remnants intangible.
The mission to discover facts of liquid water on Mars, and the disclosures that have turned up all along the way, have altered our outlook of the red planet from a dry and dead planet to one where life might perhaps have flourished and even live still.
"We are positively on the path to exploring the habitability of Mars — what it's been similar in the history and even potentially at the present," said Michael Meyer, lead scientist for NASA's Mars Exploration Program.
