ISRU Implications for Lunar and Martian Plume Effects
Philip T. Metzger, Xiaoyi Li, Christopher D. Immer +1
Experiments, analyses, and simulations have shown that the engine exhaust plume of a Mars lander large enough for human spaceflight will create a deep crater in the martian soil, b…
Modification of Roberts' Theory for Rocket Exhaust Plumes Eroding Lunar Soil
Philip T. Metzger, John E. Lane, Christopher D. Immer
Roberts' model of lunar soil erosion beneath a landing rocket has been updated in several ways to predict the effects of future lunar landings. The model predicts, among other thin…
Cratering of Soil by Impinging Jets of Gas, with Application to Landing Rockets on Planetary Surfaces
Philip T. Metzger, Bruce T. Vu, D. E. Taylor +9
Several physical mechanisms are involved in excavating granular materials beneath a vertical jet of gas. These occur, for example, beneath the exhaust plume of a rocket landing on…
Empirical Scaling Laws of Rocket Exhaust Cratering
Carly M. Donohue, Philip T. Metzger, Christopher D. Immer
When launching or landing a spacecraft on the regolith of a terrestrial surface, special attention needs to be paid to the rocket exhaust cratering effects. If the effects are not…
