Moon base! Use it as a grand first step towards actual off-world infrastructure to allow us to more easily explore the system. Helium-3 mining, manufacturing, bigass telescopes free from the interference of atmosphere, all that shizz. Establish a small self-sustaining colony, and you also back up the human race when we inevitably tit up the planet too much to live on.
