NASA’s “Chariot” to roam the moon
Feb. 1, 2008
When this hot rod rolls out on the street, traffic stops and people stare.
People aren't quite sure what to make of the bright-white vehicle with gold rims and gold trim that is a cross between an off-road vehicle and someone's fantasy hot rod.
This vehicle is dubbed the Chariot by the design team at the Johnson Space Center. This team was given one year to design and build this ultimate concept lunar rover.
Lucien Junkin, a 17-year veteran of the NASA robotics program, is the chief engineer for the project, and he could hardly wait to get started on designing a new lunar rover. "We built this vehicle in 12 months. Our mandate was building a truck that could go to the moon. When we return to the moon, we will need a utility vehicle, a lunar truck if you will."
NASA is planning to return to the moon by 2020 and is well along the design process with a new capsule called Orion, which looks remarkably similar to the original Apollo, which carried the first U.S. astronauts to the moon. The plan is to build a colony on the moon, so clearly the astronauts will need transportation to explore.
Junkin's Chariot doesn't bear much resemblance to the first-generation lunar rovers. "It challenges all the conventional wisdom of astronauts sitting as they drive. Our crew members will stand up, and we can carry more than two astronauts. The Chariot can move in a crablike motion from side to side as well as forward and reverse. It has six wheels instead of four wheels."
Harrison Schmitt and Gene Cernan were the last two astronauts to visit the moon during Apollo 17 in December 1972. Schmitt was the last person to drive a lunar rover. The new team asked him for advice before it started building the rover.
Schmitt told designers a lower step on the rover would make it much easier for the astronauts to get on board.
"The spacesuits were bulky and not that flexible. My own weight plus the total weight of the suit and life support system totaled about 370 earth pounds, even though the weight on the moon was only about 61 pounds," he told ABC News.
But he added, "We were happy with our rover, it performed very well. … What we used on the moon with Apollo 15, 16 and 17 was a four-wheel vehicle with independent drive on each wheel, front and rear wheel steering, which you could use independently."
