The NASA rover Curiosity has beamed back pictures of bedrock that suggest a fast-moving stream, possibly waist-deep, once flowed on Mars — a find that the mission's chief scientist called exciting.
There have been previous signs that water existed on the red planet long ago, but the images released Thursday showing pebbles rounded off, likely by water, offered the most convincing evidence so far of an ancient streambed.
There was "a vigorous flow on the surface of Mars," said chief scientist John Grotzinger of the California Institute of Technology. "We're really excited about this."
Water on mars would be an extreme breakthrough in exploration. It provides evidence to further explore planets and outer space because water on mars would mean that long ago there could have been life. Life on another planet is hard to imagine for people of today's world because everyone is so obsessed with their own life, but in my opinion a discovery of other life forms would break this vicious cycle society has put its self in. Just by knowing that other life forms exist would expand peoples minds and ideas and possibly technology. I believe even more money should go into outer space exploration than already is because if we stop exploring than we stop learning.
So true. I totally think this is exciting! You know, sometimes people get discouraged when there aren't any terribly significant finds in the field of outer space studies, but things like this prove that it's all worth while! We should keep it up, I'm excited now! Exploring the unknown is always an edge-of-your-seat experience! Especially when it can change the human species' lives so drastically.
