The NASA Institute for Advanced Concepts is now closed, but for about a decade, it was a think-tank that worked on (obviously) highly advanced and even speculative areas such as advanced propulsion (light sails, antimatter, etc.) or giant telescopes (liquid mirrors, Fresnel lenses.) The web page is still working, and one can access over 100 articles. One that caught my eye: "Exploration of Jovian Atmosphere Using Nuclear Ramjet Flyer" Some of these articles are speculative, and there may even be some errors mixed in.
This link is the sitemap, click on "Funded Studies" for these major papers.
