Weekly Challenge #54: Miniature Mission
This week we'll be miniaturizing, aggressively. You're to build and fly the lowest-possible-mass craft you can that can deliver a kerbal to and return them from one of the following locations:
The surface of the Mun
The surface of Duna
The surface of Tylo
The surface of Moho
The kerbal must plant a flag and return safely to Kerbin. Make full use of low-mass parts like the grumble seat, Oscar-B tank, Ant engine, and your kerbonaut's RCS pack to perform the maneuvers you need. Screenshot the mass of your vehicle before launch and show everyone how looooow you can goooooo!
