Bill Ingalls is the senior photographer for NASA, and has been for quite a while. His photographs are simply astonishing and demonstrate a unique lens on the space agencies activities over the decades. This link is a collection for those who appreciate not only space science, but the artistic quality of photography. You can always identify a Bill Ingalls image because of some intangible quality with beauty.
He is also on flickr: https://www.flickr.com/people/ingallsimages/
and on Instagram as he documents launchings and landings (often from the air suspended from a helicopter).
For those interested in space science or simply photography, this is the bar to set and his work serves as a powerful example to those who aspire to enter the fields. He is right now in Baikhonur awaiting the return of astronauts from the ISS (and probably there for another launch as well which can always be found on NASA TV at http://www.nasa.gov
