1.	Which feature opportunity did Mars Rover finds evidence recently?
Answer» NASA's Opportunity Mars rover is examining the edge of a crater on the red planet that may once have been a lake of liquid water. It found rocks at the edge of Endeavour Crater that were either transported by a flood or eroded in place by wind. The Opportunity mission has been investigating sites on and near the western rim of Endeavour Crater since 2011.
