This is the Nautilus X spacecraft in Minecraft. The Nautilus X is a concept spacecraft design by NASA for a reusable interplanetary spacecraft. My version was built over the course of 3 days and roughly 10 hours of work. It features several modules, a centrifugal ring, a full interior and the Orion Spacecraft. It is 114 blocks long, 77 blocks wide and 49 blocks high. Hope that you enjoy it!
