I know a real rocket scientist.
His name is Russell Sargent and the first spacecraft he worked on, called Cygnus, recently arrived at the international space station. He built the guidance and some of the navigation software for demos 3 through 5, and also helped to design the approach trajectory in the last figure shown here. The mission went very successfully, and now leaves NASA with a cheaper alternative to bring cargo into space. Very cool.
I talked with Russell about his current project: the Dream Chaser, a new commercial mini-space shuttle. He’s building the autopilot during entry and training astronautics how to fly it in the NASA simulator.
