Rediscovered Apollo data gives first measure of how fast moon dust piles up

Scientists used rediscovered Apollo data to make the first determination of how fast lunar dust accumulates. It builds up unbelievably slowly by the standards of any Earth-bound housekeeper — just fast enough to form a layer about a millimeter (0.04 inches) thick every 1,000 years. Yet, that rate is 10 times previous estimates. It’s also speedy enough to pose a serious problem for the solar cells that serve as critical power sources for space exploration missions.
