The Cost of Lunar Landing Pads with a Trade Study of Construction Methods
Philip T. Metzger, Greg W. Autry
This study estimates the cost of building lunar landing pads and examines whether any construction methods are economically superior to others. Some proposed methods require large…
Apollo Video Photogrammetry Estimation of Plume Impingement Effects (conference version)
Christopher Immer, John Lane, Philip Metzger +1
The Constellation Project's planned return to the moon requires numerous landings at the same site. Since the top few centimeters are loosely packed regolith, plume impingement fro…
Scaling of Erosion Rate in Subsonic Jet Experiments and Apollo Lunar Module Landings
Philip T. Metzger, John E. Lane, Christopher D. Immer +5
Small scale jet-induced erosion experiments are useful for identifying the scaling of erosion with respect to the various physical parameters (gravity, grain size, gas velocity, ga…
Lunar Dust Particles Blown By Lander Engine Exhaust in Rarefied and Compressible Flow
John E. Lane, Philip T. Metzger, Jeffrey W. Carlson
Previously we presented a numerical model that predicts trajectories of lunar dust, soil, and gravel blown by the engine exhaust of a lunar lander. The model uses the gas density,…
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…
