TL;DR: In this article, the authors present an analysis of the challenges and payoffs of a private business that harvests and processes lunar ice as the foundation of a lunar, cislunar (between the Earth and the Moon), and Earth-orbiting economy.
Journal ArticleDOI
Phenomenology of soil erosion due to rocket exhaust on the Moon and the Mauna Kea lunar test site
TL;DR: In this paper, the Apollo descent videos, terrain photography, and ascent videos are interpreted with the assistance of field experiments using a more complex regolith, which possesses embedded rocks, large fractions of gravel and dust, some cohesion, and natural geological lamination.
Journal ArticleDOI
Apollo 12 Lunar Module exhaust plume impingement on Lunar Surveyor III
TL;DR: In this paper, the impact of larger soil particles with an average of 103 pits/cm 2 has been investigated on the surface of the Surveyor III spacecraft during the Apollo 12 landing of the Moon.
Journal ArticleDOI
Jet-Induced Cratering of a Granular Surface with Application to Lunar Spaceports
Philip T. Metzger,Christopher D. Immer,Carly M. Donahue,Bruce T. Vu,Robert C. Latta,Matthew Deyo-Svendsen +5 more
TL;DR: In this article, the diffusion-driven flow in the bulk of the sand is identified as an important but previously unrecognized mechanism for erosion dynamics, and the scaling relationships and erosion mechanisms have been characterized in detail for the slow regime.
Journal ArticleDOI
Affordable, Rapid Bootstrapping of the Space Industry and Solar System Civilization
TL;DR: It has become feasible to bootstrap a self-sustaining, self-expanding industry at reasonably low cost and can be achieved with as little as 12 t landed on the Moon during a period of about 20 years, according to simple modeling.
