We were looking for a good way to browse the NASA image galleries on the iPhone, so we created this handy app for it. It downloads pictures of Apollo 11, Hubble, weird spacecraft from the 1960s, and more. You can even extend the set of bookmarks yourself to include other online photo galleries. You swipe from image to image, just like you do in the normal photo app. Try it out, and let us know if you like it!
