Here I'm undocking the ISRU lander. I wanted to design a ship that wasn't lugging around unused lander engines by having them used as part of the main engines too. The lander also has all the science tools that can be used while landed, while the main ship has the science tools that can only be used in orbit along with a lab. The lander can make it to orbit of kerbin on its own, so it should be able to handle most planets and moons. I still need to test if the whole ship has enough delta v to make it from planet to planet.
