NASA's COLDArm robot limb can handle seriously cool science

NASA is testing a new robotic arm that could revolutionize exoplanetary science for a reason most of us have probably never even considered: It doesn't need to be kept warm in order to work.  The Cold Operable Lunar Deployable Arm, or COLDArm, is being designed to operate on the south pole of the Moon, a focus of future lunar …

Frictionless materials?

> There's no lubrication used to grease the parts

What about friction? Won't they seize at some point, even without the help of the ultra-fine and pervasive lunar dust?

_{Friction between surfaces would cause abrasion, which causes dust, which in turn increases friction, until at some point the whole thing grinds to a halt.}

Bring back ROTM

Great work, really hope this goes well.

But come on:

> McCormick referenced the film Terminator 2 where the machine is temprarily stopped when frozen in liquid nitrogen. "The bad guy can't work in those temperatures, but COLDArm could," he said.

So now we're telling them where to get better parts from? Is this wise?
