The reason you seek to explore what you don't know is because you don't know what you don't know. In general I don't think people really appreciate how ridiculously little we know about everything outside of our planet. Like for instance it was only in 2013 (!!!) that it was discovered that Mars' soil is relatively 'moist', about 2% water by mass. And that's just the topsoil layer - it's suggestive that below the surface it could well be even more moist. But the Moon's much closer, so we must know more, right? Well water ice on the Moon was only confirmed in 2018!! [1] So actually starting to get surface samples, and explore more of the Moon, ideally with a rapid return to humans on it is so exciting because who knows what we'll find out next? The unknown is precisely what makes exploring the unknown so enticing, rewarding, and fun! [1] - https://www.space.com/41554-water-ice-moon-surface-confirmed... |

Thats for surface water, we confirmed a while longer the moon has water underground.
