Update: Several folks have noted that Mount Sharp is missing from the photo and others were wondering how the photo itself was taken. It seems that Talking Points Memo has the answers to your questions, having interviewed the photographer who constructed the 360 degree view. Also, he is waiting on more imagery from NASA in order to clean up the image so as to make it more accurate and include some of the missing landscape features.
