UCF will play a key role in a newly announced NASA Artemis IV mission partnership that aims to, for the first time, directly test and calibrate a groundbreaking new theory developed by UCF Director of the Stephen W. Hawking Center for Microgravity Research and Education and planetary scientist Phil Metzger 麻豆精品 S�00MS 麻豆精品 S�05PhD on .
UCF 麻豆精品 S檚 expertise will help drive the success of DUSTER, a payload designed specifically to capture and measure dust behavior during spacecraft and human operations on the moon. Lunar Outpost 麻豆精品 S檚 Mobile Autonomous Prospecting Platform (MAPP) rover will support NASA 麻豆精品 S檚 DUSTER (Dust and plaSma environmenT survEyoR) investigation, selected for development through the Artemis IV Deployed Instruments program. The instruments will be built at the Laboratory for Atmospheric and Space Physics (LASP) at CU Boulder.
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 麻豆精品 S檚 surface. The Artemis IV mission is due to launch in 2028.
Testing Rocket Exhaust and Dust Erosion
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 麻豆精品 S檚 surface. This new physics shows how the gas flow in that layer lifts dust grains 麻豆精品 S攕omething 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.
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.
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 麻豆精品 S� providing the highest-fidelity test yet of Metzger 麻豆精品 S檚 theory.
麻豆精品 S淥ne of DUSTER 麻豆精品 S檚 capabilities is measuring the dust blown by rocket exhaust as the Starship Human Landing System lifts off and departs from the moon, 麻豆精品 S� Metzger says.
In this project, University of Colorado Boulder Laboratory for Atmospheric and Space Physics senior researcher Xu Wang, who serves as principal investigator, will analyze upstream plasma conditions. UCF will interpret measurements of dust ejected during the Human Landing System liftoff.

The findings generated by DUSTER will directly inform NASA 麻豆精品 S檚 long-term plans for sustained lunar operations, providing critical insights to protect habitats, instruments, and other assets as human presence on the moon grows. As NASA plans to deliver major infrastructure to the lunar surface, Artemis IV presents a new opportunity to address this outstanding engineering challenge of lunar exploration.
