Simple Analytic Expressions for the Magnetic Field of a Circular Current Loop
TL;DR: Analytic expressions for the magnetic induction and its spatial derivatives for a circular loop carrying a static current are presented in Cartesian, spherical and cylindrical coordinates.
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.

TL;DR: To build and evaluate a small‐footprint, lightweight, high‐performance 3T MRI scanner for advanced brain imaging with image quality that is equal to or better than conventional whole‐body clinical3T MRI scanners, while achieving substantial reductions in installation costs.
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
Apollo video photogrammetry estimation of plume impingement effects
TL;DR: In this article, the plume impingement effects of the landing exhaust on the surface of the Moon were quantified using the Apollo Lunar Module landing videos and the lofted particle density was estimated at 108-1013 particles/m3.
