Eyeing Eagle Crater

How beautiful the view is now…how beautiful it must have been then. NASA announced yesterday evidence from its Opportunity Rover of a salty sea in the distant past. The evidence is quite compelling. Even though the current rovers are not best equipped to look for signs of ancient and current life, scientists admitted that if they were looking for fossils, Eagle Crater would be a great place to start.

Opportunity is expected to move on to a much larger crater that may hold even more data to help determine when the ancient sea existed, how large it was, and how long it lasted. The Mars Exploration Rover Mission site is spectacular, and according to NASA it has received more than 9 billion hits to date since the mission began.
