Honestly, I’m not completely sure what you’d do with these pictures, but they were so cool I had to include them.

The painting on this website are some of the really neat “artist conceptions” that NASA used when promoting its various space missions. This would be useful in an art class for the technique, a science class for looking at how the conceptions of space have lived up to the reality, or to a history class as visuals when looking at how humankind looked at the world and beyond in the late 20th Century.

These are really neat painting and can be used in class guilt free since they have been placed in the public domain. You can copy these for your students to use without guilt or fear of breaking copyright.
