New Analysis of LCROSS Impact Plume Suggests Cometary Source of MSP Volatiles
Revised assessment of data collected by LCROSS and LAMP instrument aboard LRO during 2009 Centaur rocket impact focuses on elemental prevalence of hydrogen, nitrogen, oxygen, and sulfur compared to carbon; Study authors from Southwest Research Institute, Johns Hopkins APL, Aix-Marseille University, UT San Antonio conclude comet origin best fits composition profile, that 1-3 m of regolith within Cabeus crater (84.9°S, 35.5°W) may predate latest volcanism (~1 Gya) and “returning humans to the Moon presents an unprecedented opportunity to determine the origin of volatiles stored in PSRs”
Proposals for excavation / conveyance of ice-containing regolith from Moon Permanently Shadowed Regions, supporting long-duration human activity receiving US$500k through NASA Centennial Challenge; Redwire Space (Jacksonville FL) receives first place / $125k for Lunar Regolith Excavator (L-Rex) and Lunar Transporter (L-Tran); Colorado School of Mines (Golden CO) second place / $75k for Lunar Ice Digging System (LIDS); Austere Engineering (Littleton CO) third place / $50k; PRIME-1 ice drill to be delivered on CLPS IM-2, Q4 2022; CNSA Chang’e-6 to retrieve MSP sample 2024
Fundamental and Applied Lunar Surface Research in Physical Sciences is focus of LSSW 10, with plenary talks including Artemis update from (L-R) Julie Robinson, NASA HEOMD Chief Scientist; A.V. Zakharov, Astronomer with Space Research Institute of the Russian Academy of Sciences to present on Luna-25 instrument PmL, planned to conduct Lunar Near-Surface Dusty Plasma Investigations; S. Bandyopadhyay to expound on NIAC-awarded farside Lunar Crater Radio Telescope (LCRT) concept, C.J. Collins invited to speak on Instrumenting the Moon as a Spherical Gravitational Wave Detector
Oxygen, Key Element For Sustaining Human Life And Powerful Source Of Propulsion Fuel, May Be Refined From Moon Regolith Using ISRU Version Of Electrolysis Process Currently Employed In Earth Mining; ESA Contracted Rotherham-Based Metalysis To Develop Method Tailored For Lunar Surface; Composition Of Regolith Estimated 45% Oxygen By Weight; Process Requires 950°C Molten Salt Bath; Iron, Titanium Extraction Byproducts Useful For 3D Printed Construction; ESA Materials Engineer Advenit Makaya, Project Lead, Indicates Extraction Technology Demonstration Is Oxygen Plant Precursor
