Mars: Dead or Alive; Welcome to Mars


The viewer is there to see problems discovered and overcome: the faulty parachute design, the punctured airbags and Spirit's boot-up problems on Mars.
Mars Dead or Alive ends with the successful touchdown of Spirit; Welcome to Mars rejoins the story at that point and follows the two rovers in their quest to find evidence that water existed on our planetary neighbour.
The two programs, which originally screened on the PBS channel in the USA, are rich with explanatory graphics and dramatic images from Mars itself. They also convey, with a compelling sense of drama, the tension when things don't go to plan: the sleep-deprived faces, the hot, grim silences, the empty pizza boxes littering desks.
