Just to mention a recent series about Mars produced by National Geographic. The idea is to link a very well made sci-fi series with reality. Real interviews are shown (Elon, Zubrin and others) as long as the fictional series novel develops. They link the episode subject (landing, radiation, etc) with real challenges for the real astronauts and how they will try to overcome difficulties when on Mars. Worth to see.
