What is the relationship between NASA and the DND and the Pentagon? How do they work with each other, if they do?
If you mean DoD, the relationship is minimal. Data from some NASA EO satellites has been used by the military, and military installations and facilities are sometimes used for NASA activities (I think Dugway Proving Ground, which was supposed to be where the Genesis capsule was recovered over, and which it actually crashed into, is a DoD site.)
