Hawai’i Planetary Scientists & Engineers Work to Characterize Lunar Moisture, Develop Basalt ISRU Building Technique
In Situ Detection of Water on the Moon by the Chang’e-5 Lander, a collaborative research effort between Shuai Li of University of Hawaii Mānoa and Honglei Lin, Rui Xu of Chinese Academy of Sciences details Lunar Mineralogical Spectrometer data taken from ~1.4 m elevation at Chang’e-5 landing site (43.06°N, 51.92°W), finding <120 ppm water content in regolith; PISCES advancing basalt sintering process under NASA STTR phase 1 funding co-awarded with Masten, may build prototype extruder under phase 2 with goal of ISRU on Moon
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
Researchers with Indian Institute of Remote Sensing and U.R. Rao Satellite Centre, divisions of ISRO, confirm presence of lunar water H2O) in 
NASA Moon Rover VIPER Meets Risk, Cost And Schedule Constraints Of ‘Key Decision Point C’ Internal Assessment, Clearing Way For Operational Planning And Construction; 1.5×1.5×2.5m, 430kg Vehicle To Be Built At JSC With Instrument Input From KSC / Honeybee Robotics, Managed From Ames Research Center, Is To Land Late 2023 Via Astrobotic Griffin In MSP Region For ~100 Day Mission During Which 1-Meter TRIDENT Drill And 3 Spectrometers Will Be Controlled With Little Lag From Earth Through X Band / Deep Space Network As Volatile-Seeking Mission Traverses 20km
LRO Data Indicates ~10-20% Of PSRs Sufficiently Cool (<110 K) To Allow Ice Formation Are Depressions Casting 1-cm – 1-km Shadows, Widely Dispersed Across Moon Polar Regions (>80° Latitude); Inclusion Of “Mini Cold Traps” In Study By UC Boulder / PSI Researchers Suggests Total Possible Lunar Ice Containing Area Is ~40,000 km2 (23,000 km2 Within <20° Moon South Pole, 17,000 km2 Within <20° Moon North Pole); Total PSRs Comprise Just 0.15% Of Total Surface Area; Relatively Small Cold Traps May Offer More Favorable Mission Parameters Than Large Craters
