If it came from NASA, it most likely is either Kodak or Agfa film. Let's assume Kodak. It could be either aerial film (very likely for 70mm) or cine film or ordinary still film. Since it came with that back and is unperforated, it is unlikely to be cine film. It could be either negative or positive. Many Kodak negative aerial films did not have an integral orange mask, but they were compatible with C-41 processing. My guess is that it is aerial film.
