NASA uses PubMed to preserve and deliver freely its publications with public funding (called PubSpace).

The database is called PubSpace, and the public can access NASA-funded research articles in it by searching for whatever they’re interested in, or byjust browsing all the NASA-funded papers.
“Making our research data easier to access will greatly magnify the impact of our research,” said NASA Chief Scientist Ellen Stofan. “As scientists and engineers, we work by building upon a foundation laid by others.”
Right now, there are some 861 research articles in the database, and you can expect that number to keep rising as NASA-funded researchers get on board with the new policy.
