I’m not sure about the NASA name itself, but apparently the graphic stuff is protected by a special law:

So you wouldn’t exactly get a copyright claim when abusing the NASA logo but it’s still illegal.

I couldn’t find anything about the NASA word itself though, just some articles reciting guidelines by NASA not to imply an endorsement by NASA. I don’t know how that’s enforced though.

You cannot _misuse_ any official government logo or seal. Which effectively means creating a fake document with a real seal and then publishing it. The concern is fraud not sharing content.

You are allowed to basically reproduce the work without any worries whatsoever.
