NASA does research. It also publishes research. The latter is a subset of the former and we don't know how the subset compares to the superset.

I can access what it has published in 2016 which I couldn't access in 2015.

I'm not aware of, or know, everything an organization with a $20 billion budget this year and roughly 4% of the US GDP during the Cold War ever did and found there's no difference between that and what it published..

My comment was because I assumed that NASA didn't publish all its research before. Considering the size of that knowledge base, is this assumption so stupid and negative to deserve to be downvoted that much?
