Roving Mars [Blu-ray]

At NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, we see highly skilled engineers addressing every challenge and every possible contingency, and project leader Steve Squyers serves as our informative host and enthusiastic populist for space exploration. After launching in June and July of 2003, the rovers traveled for seven months and 300 million miles to Mars, landing on the red planet in January 2004. Every aspect of the mission is covered in concise detail, and tension escalates as touch-down (achieved with the now-familiar "bouncing balloon" landing system) draws near. What's most remarkable, even to the crew at JPL, is that Spirit and Opportunity succeeded far beyond their mission expectations, becoming one of NASA's most triumphant achievements in interplanetary exploration. The photos, chemical analyses, and other data gathered on Mars were intended to prove the past existence of water on Mars (and hence the possibility of life), and in this and many other respects, Roving Mars stands as a breathtaking tribute to the men, women, and robots who've given us a greater understanding of the planetary system we call home. --Jeff Shannon

On the Disc
Roving Mars is accompanied by two excellent bonus features. First up is "Mars: Past, Present, and Future," a 25-minute "making of" featurette that provides additional educational detail about our closest planetary neighbor, along with behind-the-scenes footage and interviews with key personnel at NASA's Jet Propulsion Laboratory. Then comes the 50-minute featurette "Mars and Beyond," originally broadcast in 1957 as an episode of Walt Disney's popular Disneyland TV show. Typical of that series, it's a wildly imaginative, cleverly animated look at Mars and its significance in the history of mankind. Even after more than half a century, it's filled with scientific and speculative details that are sure to engage anyone's sense of wonder. --Jeff Shannon
