Lunar Cold Trap Contamination by Landing Vehicles
Scott T. Shipley, John E. Lane, Philip T. Metzger
Tools have been developed to model and simulate the effects of lunar landing vehicles on the lunar environment, mostly addressing the effects of regolith erosion by rocket plumes a…
Further Analysis on the Mystery of the Surveyor III Dust Deposits
John Lane, Steven Trigwell, Paul Hintze +1
The Apollo 12 lunar module (LM) landing near the Surveyor III spacecraft at the end of 1969 has remained the primary experimental verification of the predicted physics of plume eje…
Lagrangian Trajectory Modeling of Lunar Dust Particles
John E. Lane, Philip T. Metzger, Christopher D. Immer +1
A mathematical model and software implementation developed to predict trajectories of single lunar dust particles acted on by a high velocity gas flow is discussed. The model uses…
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…
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…
