NASA’s next trip to the moon will explore its south pole, an area that gets even colder than Mars. So scientists need a robotic arm system that can function in temperatures as low as minus 280 F.
Perseverance, NASA’s newest Mars rover, is living up to its name. It has already survived a hurdle no previous rover has had to face: a global pandemic.
Many lubricants and adhesives that function on Mars will degrade in the cold of a lunar night. Certain electronics that worked fine for the Mars rovers — which can take advantage of the heat trapped by the thin Martian atmosphere — won’t work on the moon either., a class of metals whose atomic arrangements more closely resembles that of glass, making them stronger and more durable than steel or ceramic.
In addition, COLDArm’s motor controllers have been fitted with an updated voltage converter that can function in extremely cold environments without the added bulk of cables or insulation, McCormick said.

Masters Live Updates | Phil Mickelson surges into contentionPhil Mickelson has turned back the clock at Augusta National. The 52-year-old Mickelson shot a 7-under 65 in the closing round of the Masters, giving himself a shot at a fourth green jacket. Lefty walked to the clubhouse with an 8-under 280 and trailing leader Jon Rahm by only two strokes. Brooks Koepka is also at 8 under. Rahm and Koepka still have eight holes to play. Mickelson can only sit back and watch, having matched his best round ever at the Masters and a score he hopes will be good enough if the final group falters.
