I’d like to see it taken in steps with a concrete long-term (50–100+ years) plan. I want to see 1–2 long life satellites in orbit around each planet and some of the more interesting moons. Give me a trio of deep space probes designed to go as far as possible as fast as possible. Develop exploration projects centered around each planet. As a core mission update the launch facilities > two reusable lift vehicle types one for cargo one for people > multipurpose robotics capable of being landed and flown on other planets > improved space suits > self sustaining, upgradable, orbital habitats > lunar habitat and science station > orbital ship yard.
Each of those steps has thousands of components that go into it many of which can be dual purpose/multi purpose. Some of that has already been started others won’t be feasible for decades. If you want to get kids interested, educate them, develop planetary and solar system exploration curriculums. Show them where they’re going and commit to helping them get there. Stream live feeds from earth orbit looking out, from the moon, from other planets looking in. Put some pride and opportunity back in the science of space exploration in all phases. Take risks. Get in the news with advancements and discoveries and stay there buy continuing to fund new and innovative projects all focused on long term goals. Don’t just tell people you’re doing it (or worse, that you’ve done it and no one noticed), tell them why and why it matters.
But, unfortunately, all that takes a lot more than a commitment from NASA.
