Explanation of Subject Categories
We have filed the GRIN photos into 93 different categories.
Many photos appear in more than one category. An explanation
of what is in each category is provided below. These categories
do not contain every image that is someway related to the
subject, just the most important. For example, Space Shuttle
missions that involved practicing for Hubble Space Telescope
servicing missions are in the database, but not included in
the Hubble category. So if you do not find what you want in
the subject categories, you should use the search function.
Keep in mind that GRIN is a selective collection, not a comprehensive
one, so you may be looking for photos that are not in the
database. Please send us suggestions for photos that you think
should be included. See the Frequently
Asked Questions for an explanation of the kinds of images
included in GRIN.
A number of the categories are currently incomplete, but
will contain photos in the future as the GRIN collection is
expanded. We may also add new categories later. Images appear
in each category according to their GRIN number, with the
lowest number appearing first.
