All of these examples of NASA alien encounters, with the exception of the second-to-last one, were captured on film by NASA astronauts or Russian Cosmonauts over the past half-century - each of them amazing examples from different eras - Gemini, Apollo, Apollo/Soyuz Test Project, Skylab, STS, the ISS, plus a couple Russian-source additions from their unmanned Zond and Mir Space Station programs as well thrown in to round things out.
These are just the NASA alien encounters that have been made public. How many NASA alien encounters have been covered up or classified?
