As I said before, the Lunar Module [1] is awesome. It can dock. It can land two people on the moon. It can support them on the surface of the freaking Moon for longer than three days. It’s a moon rock transporter and impromptu TV studio. It can freaking ascend again. And in this case the descent engine could be used for necessary course corrections [2]. Is there anything this truly marvelous piece of technology can’t do? :)
