The great PBS science series Nova scores another hit with Mars: Dead or Alive, capturing all the excitement surrounding the Mars rover landings of early 2004. Originally broadcast just as the first of the twin rovers ("Spirit" and "Opportunity") was experiencing temporary communication problems with Earth-bound mission controllers, this riveting hour-long episode chronicles the risky $820 million Mars Exploration Rover (MER) project from design to touchdown, dramatically illustrating (through the use of detailed simulations and sophisticated computer animation) the considerable chances of failure--a nail-biting gamble considering that fully two-thirds of all previous Mars missions never reached their destination.
