Midnight Mars Browser
(abreviated MMB) is a computer program I wrote to download and look at the raw images from the Mars rovers Spirit and Opportunity. Basically, MMB downloads the raw images from the rovers that NASA/JPL posts on the Internet, and lets you view them in slideshows or "you-are-there" Panorama views.
MMB is an "enthusiast's" tool; I am not connected with NASA or JPL in any way. If you want to learn more about what the program does, read the Introduction in the ReadMe.
