You pretty much can't. NASA employs few if any astronomers. NASA is an engineering organization, not an astronomy group.
Even say, the Hubble Space Telescope. It was designed, launched, and repaired in orbit by NASA. NASA has absolutely nothing to do with actually using the telescope for astronomy.
That is handled by the Space Telescope Science Institute. Which is run by the Association of Universities for Research in Astronomy. In other words, all of the astronomers actually working on it are university employees.
Several of the universities that are members aren't even in the United States. Those university employed astronomers have phd's. That's your first step.
NASA employs many research scientists, though more of them are planetary scientists (including earth scientists) than astronomers. The best way of making a connection with NASA is to attend an undergraduate institution that has an immediate connection with a NASA research facility. Caltech, Stanford, Columbia, Rice, or the University of Alabama at Huntsville.
If you can do undergraduate research on a NASA project, your chance of sustaining or renewing that connection in your professional life is good.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
