The future of the KSA and space travel could hold many exciting things; there's honestly too much to imagine. It really depends on what you mean by "future". If you mean near-future, then we could see things like landings on asteroids and comets, crewed missions to Duna, small bases on Minmus, and a lot more than just that.
BUT, if you mean far-future, then well, we are looking at a LOT more exciting opportunities and more potential than ever. Interstellar travel, finding alien life, and potentially even first contact.
The possibilities for both are basically endless, but one thing is for sure. We will continue to look up and ponder about the kosmos, even if we may never reach some places. Kerbalkind will always strive for more, and we will always attempt to reach those goals we set.
