Below are thumbnails of pictures taken by the Mars Twin Rover Opportunity which landed about 12:05 a.m. EST on Sunday January 25, 2004. Hold the mouse pointer over each thumbnail for a description of each picture. Click on a thumbnail for a larger picture. Going from left to right and top to bottom, the newest pictures are listed first with the oldest pictures listed last. Most if not all of the following pictures have had their resolution reduced in Adobe Photodeluxe to reduce their file size. The advantage of this is that the picture will load faster when you download it and will look fairly good when viewed on a monitor. So think of the pictures on this website as a good preview of the original pictures on NASA's website. The pictures on NASA's website are larger and sharper. So I will try to provide a link to the original picture on NASA's website when possible.
