DUSTER represents the best opportunity to date to evaluate the theory on the physics of dust erosion, with implications for the activities being planned on the moon/news/wp-json/wp/v2/posts/150206/u2019s surface. The Artemis IV mission is due to launch in 2028./news/wp-json/wp/v2/posts/150206/nPhil Metzger gave the closing address at the Economist Space Economy Summit, held at UCF during Space Week this year./news/wp-json/wp/v2/posts/150206/nTesting Rocket Exhaust and Dust Erosion/news/wp-json/wp/v2/posts/150206/n This theory introduces a fundamentally new understanding of the behavior of gas in the boundary layer, the thin region where rocket exhaust meets the moon/news/wp-json/wp/v2/posts/150206/u2019s surface. This new physics shows how the gas flow in that layer lifts dust grains /news/wp-json/wp/v2/posts/150206/u2014something no previous model could adequately explain. Before this breakthrough, NASA lacked a method to reliably predict how much lunar dust erosion a landing or departing spacecraft would generate, and therefore could not fully estimate how much sandblasting damage would occur to hardware on the moon./news/wp-json/wp/v2/posts/150206/n
However, several key parameters in this new model cannot be measured accurately using existing lunar data or Earth-based experiments. On Earth, large-scale testing is limited: rocket exhaust cannot be blasted into a vacuum chamber without destroying the vacuum, and gravity cannot be reduced to lunar levels for the necessary full-scale trials./news/wp-json/wp/v2/posts/150206/n
DUSTER will change that. By collecting data during actual Starship Human Landing System operations on the moon, DUSTER will allow scientists to measure these long-elusive parameters directly in the lunar environment /news/wp-json/wp/v2/posts/150206/u2014 providing the highest-fidelity test yet of Metzger/news/wp-json/wp/v2/posts/150206/u2019s theory./news/wp-json/wp/v2/posts/150206/n
