It’s low mileage, it provides a comfortable set of wheels for occupants, but it only goes 6 mph. And where this ride will go on off-road trips is truly out of this world.

NASA is testing a luxe moon buggy that never will get a speeding ticket.

The Small Pressurized Rover, or SPR, is as far removed from the original moon buggies of the Apollo missions as a Mustang GT 500 is from a Ford Model T.

While the original moon buggies were little more than a chassis and engine with seats for astronauts who had to wear spacesuits or die, the SPR has an air conditioned passenger cabin where astronauts will be able to relax in street clothes (though there may be no streets on the moon at first), and enjoy the view of the lunar scenery.

NASA has begun testing the SPR in Arizona, where the landscape resembles that on the nearest neighbor to Earth.

A collection of engineers, astronauts and geologists have spent the past week testing out the SPR in the 11th annual Desert RATS – or Research and Technology Studies — field tests.

Two teams of one astronaut and one geologist each have been driving the rover through the Arizona desert, trying it out in two different configurations. One configuration is like the old moon buggies, where astronauts are outside, exposed, and must wear spacesuits.

But the second configuration, the SPR, adds a module on top of the rover chassis that the crew can sit inside as they drive the vehicle, donning spacesuits whenever they want to get out. They access the suits from inside the passenger cabin, through suitports.

That isn’t as tough as it used to be. NASA wants lunar spacesuits that can be entered through the back of the suit, which is connected to the module.

For the first week of tests, the rover has been driven on day-long trips to determine how each configuration performed. These have been some of the longest drives the prototype has ever made, but next week the group will step it up another notch or two, by going on a three-day drive through the desert in the SPR to determine how it performs and whether it’s comfortable enough for long-duration trips.

Trips of more than 600 miles will be possible. At that rate, in 100 trips it would use up its 60,000-mile warranty.
