Developed in only 17 months at a cost of 38 million dollars, the
Lunar Roving Vehicle (LRV) greatly expanded the survey range of the
astronauts on Apollo 15, 16 and 17. Designed to operate in the
low-gravity vacuum of the Moon, the LRV boasted an ingenious design
that allowed it to be folded up and stored inside the Lunar Module.
It would then be deployed using a system of pulleys and brake
reels. The LRV's frame was made of aluminum alloy 2219 tubing
assemblies, giving the vehicle a fairly small mass of 210kg but
allowing it to carry up to 490kg on the lunar surface. The LRV's
lightweight tires were made of zinc-coated steel strands with
titanium chevrons and aluminum hubs, and offered a ground clearance
of 36cm. The LRV featured two side-by-side, foldable seats, a TV
camera, and a dish antenna. Four independent DC motors - one for
each wheel - powered by two 36-volt batteries provided maneuvering
power. Both sets of wheels could be used to steer, although they
could also be decoupled. For safety reasons, astronauts never drove
the LRV a distance farther from the LM than they could safely walk
in the unlikely event that the rover failed. On each of the three
day missions that it was employed, the LRV was used daily for three
traverses. The longest was on Apollo 17, when it was driven 20.1km,
and it traveled a total of 35.9km on that mission. The total
distance traveled by all three LRVs was 90.4km. Almost all of it
was done without incident, although some damage to the fender
extensions caused dust problems on Apollo 16 and 17. Harrison
Schmitt of Apollo 17 praised the design and operation of the
vehicle, saying ..".the Lunar Rover proved to be the reliable, safe
and flexible lunar exploration vehicle we expected it to be."
Originally created for the astronauts by prime contractor Boeing,
this Lunar Roving Vehicle Operations Handbook describes the LRV and
its systems, and details the deployment and driving procedures. It
also details the 1-gravity LRV used to train astronauts on Earth. A
lengthy appendix provides performance and other data.
