The Surface of the Moon is Electrically Charged, Which Could Allow a Hovering Robot to Explore it - Universe Today universetoday storybywill
. On the Moon, this surface charge is strong enough to levitate moon dust more than 1 meter above the surface. With support from NASA, this research could lead to a new type of robotic exploration vehicle that will help astronauts explore the Moon in the coming years.
at MIT . Along with engineers from NASA, the team investigated how a lunar glider made of Mylar could take advantage of the Moon’s natural surface charge. Their research is summarized in a paper that recently appeared in theMuch like how a MagLev train relies on magnetic induction between the train cars and the tracks to travel at very fast speeds, this Mylar glider naturally holds the same charge as surfaces on airless bodies.
Oliver Jia-Richards, a graduate student at MIT AeroAstro, was the lead author on the study. As he said in a recent MIT News“We think of using this like the Hayabusa missions that were launched by the Japanese space agency. That spacecraft operated around a small asteroid and deployed small rovers to its surface. Similarly, we think a future mission could send out small hovering rovers to explore the surface of the moon and other asteroids.
The vehicle was suspended over an aluminum surface equipped with two springs calibrated to compensate for Earth’s gravity and a tungsten rod to measure how much force the thrusters produced when fired. The entire setup was then placed within a vacuum chamber to simulate an airless environment, and the team applied various voltages to the thrusters to calculate the height the vehicle could achieve.
