This is the first 360 degrees view taken by the Mars twin rover Spirit. This picture is made up of 225 different pictures that have been pieced together like a puzzle to show a continuous view in every direction. In other words the Mars twin rover Spirit started taking pictures at one point and keep turning its camera around in a circle taking more pictures until it got back to its beginning point. Then all the pictures it took were pieced together to form the picture below. The original picture can be found here and has a file size of 13 MB. (Jan 12, 2004)
