MARS
National Geographic, 9:00 p.m. ET
MINISERIES PREMIERE: This six-part documentary series about the feasibility of a manned space expedition to Mars, with scripted fictional elements imagining a possible future on another planet, comes from Ron Howard, whose Apollo 13 movie was one of the best space films ever made. He’s reason enough to go on this particular journey – but the planet Mars, which has inspired some of the best science fiction ever written, is even more compelling. For a full review, see David Hinckley’s All Along the Watchtower.
