This episode of MOON MACHINES immerses viewers in the incredible story of the mighty Saturn V moon rocket � technology that joined the vision of World War II German rocket scientists with that of a generation of young, dedicated engineers from across the United States. With the backdrop of Russia�s Sputnik launch and President Kennedy�s ambitious commitment to reaching the moon, engineers and scientists would produce a 363-foot-tall rocket with more than one million working parts that delivered 7.5 million pounds of thrust. Saturn V was so large that even those who built it were amazed and could hardly believe its power.

In the early days of the Apollo project, grand ideas were devised for how to travel on the moon. With excitement running high and "GO" fever very much the buzz, engineers came up with all manner of vehicles for traversing the new frontier. But one by one the projects were shelved as each was deemed too expensive or too dangerous. Lunar Rover reveals the untold story of how a small team of engineers convinced NASA to build what ultimately became the Lunar Rover. The greatest challenge for the Lunar Rover team was to design, build, test and deliver the final flight-worthy product to NASA in less than 18 months.

The Shroud of Turin is one of the great enduring mysteries of all time, with its authenticity debated for years. Many believe it's the burial cloth of Jesus and the only physical link to Him, while others maintain that it is nothing more than an elaborate hoax. In fact, in 1988, a team of scientists radiocarbon dated the Shroud and concluded it was fake, dating back to the Middle Ages (1290-1360), long after Jesus was crucified. And that's where the story stood, unchallenged -- until now.

The Shroud of Turin is one of the great enduring mysteries of all time, with its authenticity debated for years. Many believe it's the burial cloth of Jesus and the only physical link to Him, while others maintain that it is nothing more than an elaborate hoax. In fact, in 1988, a team of scientists radiocarbon dated the Shroud and concluded it was fake, dating back to the Middle Ages (1290-1360), long after Jesus was crucified. And that's where the story stood, unchallenged -- until now. Discovery Channel's one-hour original special UNWRAPPING THE SHROUD: NEW EVIDENCE attempts to unravel the truth about the cloth on Sunday, December 14, 2008 from 10-11PM ET/PT. The special event features the story of Ray Rogers, a respected chemist from the Los Alamos National Laboratory in New Mexico and member of the original team of scientists who examined the Shroud. Rogers came across a paper written by a husband and wife from Columbus, Ohio that claimed the 1988 radiocarbon dating was inaccurate. According to the couple, the test sample that was used had been taken from a section of the Shroud that had been repaired in the 16th Century, skewing the results. Expecting to prove this couple wrong, Rogers went back to examine the sample of the Shroud he tested years earlier, and what he found astonished even himself. In his last days (he had been battling cancer), Rogers made a video -- which before now has never been seen -- detailing his conclusions.

When the USS Macon met its end, the Navy's zeppelin ambitions died with it. The USS Macon was one of only two flying aircraft carriers ever built. The other was her sister ship, the USS Akron. The Macon was built by Prague-born engineer Dr. Karl Arnstein in Akron, Ohio. Her first flight was in April 1933. Both the Macon and the Akron were capable of carrying small F9C “Sparrowhawk” propeller planes, which were launched and retrieved during flight. The Macon was 785 feet long. The wreck site of the Macon was finally discovered in 1990, 55 years after it sank to the bottom of the Pacific Ocean off the coast of California. A fisherman who had marked the exact coordinates where he'd lost a net assisted the Monterey Bay Aquarium and the Navy with locating the site. The crash was caused by a violent storm, which tore off the upper fin of the Macon and sent her spiraling down into the sea. The ship landed gently before it sank, however, and only two of eighty-three men were lost. The Macon’s site is the best documented underwater site in the world apart from the Titanic. The wreck site remains secret to the public. It lies within a marine sanctuary and is not accessible to divers due to its depth. The hangar for the USS Macon, which is large enough to fit three Titanics, still stands in Sunnyvale, California. A new zeppelin will soon be delivered to the site, which will then open as a tourist attraction. In its heyday, the Macon was used for scouting purposes over the Pacific Ocean. Some historians believe that the attack on Pearl Harbor might have been prevented if the ship had still been in use.
