The NSSDCA Photo Gallery is intended to fulfill two different purposes. The first of these is to provide access to some of the more popular NASA images available to the public. Historically, NSSDCA filled hundreds of requests per year for thousands of photographs, but many of the same images are requested time and again. Many (if not most) of these are provided in the Photo Gallery.
The second purpose of the Photo Gallery is to provide examples of images produced from CD-ROM data. We get many questions about how to use the data on the CD-ROMs we distributed and some selected examples of the kind of manipulations which can be performed on them are available in the Photo Gallery.
The images presented in the Photo Gallery have a number of different sources, primarily NASA missions, however. They are generally organized by object and/or phenomenon on separate pages. The source of the image as well as the processing involved in producing the image have been included wherever possible. Photo captions for some images are also available.
