Nexus Crew [Block B]

An improved Nexus Crew. Instead of using the second stage as a service module, it instead has its own, which gives it far more Delta V, allowing it to go to low lunar orbit (RSS) and back. With a reusable service module that parachutes down into the sea, this is the world’s first fully reusable medium-lift crewed LV. It also has windows, allowing for more appeal to space tourists, and letting the astronauts see the pretty view lol. It also has a window in the docking port, though in-game, there is a bug where if you turn off the docking AG while burning your engine, the closable nosecone falls off.

NOTE: Before separating the CSM from the second stage, make sure to turn on the heat shield AG or the heat shield will break.
