This had got me talking to myself

This is a note to myself. Self I want you to go look up the possibility of using a very lightweight vehicle to land on the moon using off the shelf components as much as possible. Come to think of it I did this thought experiment not too long ago with a dragon capsule. You need something for reentry, but do you have to carry it with you all the way to the moon and back? Perhaps you can get a better solution to that problem. As always, the less mass that you use the better.
