We are told by NASA that the lunar rovers were built of such lightweight construction that if an astronaut was to sit on one here on Earth it would collapse, yet basic physics tells us that if an astronaut can't sit on a rover on Earth without breaking it, then he certainly cannot drive one on the Moon. The equation for force is Newton's F = ma, weight doesn't enter the equation at all, only mass, which is the same for the rover on the Moon as it is on Earth.
The very simple and proven equation of F = ma proves the forces the rover will come under being driven on the Moon are the same as they are on Earth. If a rover is driving along at 10mph and hits a pothole the forces the rover comes under are the same on the Moon as on Earth, if the vehicle lurches upwards it will rise 6 times higher on the Moon, so, if the rover rises one inch on Earth then the same rover at the same speed will rise 6 inches on the Moon, they will both land with the same force from the differing heights. It is therefore impossible to make a vehicle so weak that it can't be sat on here on Earth and then take it to the Moon and drive it at any speed on an uneven terrain. Similarly, for acceleration a formula is a=F/m, and that equation is the same on the Moon as it is on Earth, or even in space. The moon rovers had 1/4 hp electric motors for each wheel, that's a grand total of 1 horsepower to drive an estimated 1500lb mass, don't forget that the mass of the rovers is the same on the Moon as on Earth, and the power needed to drive that mass is also the same, all that the Moon's lower gravity will do is make the rover lighter on the moon's surface and cause traction difficulties. ![]() This has 1 hp, imagine putting 6 or 7 big blokes on it and taking it for a spin, how much performance would you get? On the moon they hooned around with a mass of near 1500lbs with the same motor power as the wheelchair, they not only got great performance but had no noticeable traction problems due to 1/6g. I call shenanigans. |
