Ticonderoga Apollo Recovery (CVS 14) - Naval Cruise Book

The LRV was used to transport the two astronauts on their three exploration traverses of the Moon's Descartes region. It carried tools, scientific and communications equipment, and the lunar samples which were collected along the way. This four-wheel, lightweight vehicle greatly extends the lunar area that can be explored by man. It is the first manned surface transportation system designed to operate on the Moon, and it represents a solution to challenging new problems without precedent in Earth-bound vehicle design and operation. lt must operate in an almost total vacuum under extremes of surface temperatures, low gravity, and on unfamiliar terrain. The LRV is 10.2 feet long, has a six-foot tread width, is 44.8 inches high, and has a 7.5 foot wheel base. lt weights 457 pounds and cost the American taxpayer over 8 million dollars. Each wheel is powered by a small electric motor f4-wheel drivej. The maximum speed attained on the Moon was about 8 miles-per-hour. It is powered by two 36-volt batteries, and either battery can run all systems that are electrical. The front and rear wheels have separate steering systems, if one fails, it can be disconnected and the LRV will operate with the other system. The Moon Buggy can carry about 1,080 pounds, more than twice its own weight. It is designed to operate for a minimum of 78 hours during the lunar day and can travel up to about 57 miles total distance on its two batteries. The maximum range, for safety's sake, that the astronauts were permitted to travel from the lunar module was approximately six miles-a long distance over unfamiliar, unexplored terrain. This distance is based on the walk-back distance verses the time limitation of oxygen and coolant available in the astronaut's portable life support systems. This six mile radius area contains about 113 square miles available for investigation, 10 times the area that can be explored on foot. The vehicle can negotiate obstacles one foot high, and cross crevasses 28 inches wide. The fully loaded LRV can climb and descend slopes as steep as 25 degrees, and park on slopes up to 35 degrees. Both crewmen sit so the front wheels are visible during normal driving. The driver uses an onboard dead reckoning navigation system to determine direction and distance traveled at any point during a traverse. Rover has five major systems: Mobility, crew station, navigation, power, and heat control. The navigation system also has a homing-in device allowing for driving out of sight of Qrion without fear of becoming lost in unfamiliar surroundings. Rover, the Moon Dune Buggy
