Precision Technology for Landing Within Shadowed Regions of Moon Surface Sought by NASA
Nighttime Precision Landing Challenge No. 1 offers ≤US$650,000/ea for 3 proposals on lunar landing sensing systems designed to function absent light from ≥250m altitude – a common condition especially in Moon polar regions rich in volatiles such as hydrogen, oxygen, water termed Permanently Shadowed Regions, cold traps on crater floors that are seldom / never illuminated; Hardware such as optical, radar and lidar sensors coupled with machine learning software are likely approaches to challenge; Submissions accepted until 19 May 17:00 PDT
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

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
