You're now ready for the moon, congrats! This is a big step for both you and all of mankind.

There are quite a lot of resources you can find on the moon, the most notible of them being cheese. Yes, you get to go to a moon and be a rat.

There of course are other resources you should get if you want to progress further in the mod and be able to go to mars and other planets, but this is just the start of your space journey. Good luck!
