If you have some free time, check out the Air & Space Museum’s object collection of Eyewitness to Space, which showcases some of NASA’s permanent collection from their art program. I found mostly sketches from artists’ sketchbooks, but I was also surprised to see some prints. 
Giuseppe Tiberio Madeleine, Spazio E Pensurro Pa., Etching, in NASA’s permanent collection. 
Len Gittleman, Unnamed crater, 1972, from Lunar Transformations Series, Serigraph, in NASA’s permanent collection. 
Len Gittleman, Oceanus Procelarum, 1972, from Lunar Transformations Series, Serigraph, in NASA’s permanent collection. 
Jack Perlmutter, One Giant Step, Woodblock, in NASA’s permanent collection. 
Wilhelm Geissler, Kosmische Fahrt, 1966, Woodblock, in NASA’s permanent collection.

* Perlmutter was the chair of printmaking at Corcoran Gallery of Art (1960-1982) and was also the curator for the Cosmos Club featuring members of distinguished professionals and intellectuals in science and the arts.
* Robert T. McCall is well-known for his 2001: A Space Odyssey poster illustration. I love his floating worlds and visions of the future!
