India Space Research Organisation (ISRO) Determined to Land Chandrayaan-3 Near Moon South Pole in 2022

Speaking to TOI, ISRO Chair S Somanath reiterates commitment to reaching lunar surface NLT year end, claiming place in history as 4th nation with a Moon landing mission after USSR, USA, China; “Final call” on launch date will depend on orbital parameters following craft testing, including drop test / landing simulation to be carried out at Satish Dhawan Space Centre in Sriharikota similar to testing of Chandrayaan-2 in Mahendragiri with 100-m crane / bungee cord used to simulate 1/6 Moon gravity, testing maneuvering; Somanath has also made clear that Chandrayaan-3 will include a stripped-down orbiter in addition to lander and rover, despite early reports that ISRO would forgo orbiter

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”

China Shares Moon Samples / Data, Plans Lunar Orbital Relay in Support of South Pole Missions

Data from 13 institutional analyses of Chang’e-5 samples (17 g) now available from CNSA Lunar Exploration and Space Engineering Center, applications for second sample release due 15 Sept; 1,731 g total collected within Oceanus Procellarum, site officially named Statio Tianchuan per IAU; With Chang’e-6 sample return mission targeting Aitken crater in vicinity of South Pole and Chang’e-7/8 explicitly targeting MSP, CNSA plans new data relay satellite – rather than operating in L2 halo orbit, new lunar relay to transmit from highly elliptical orbit nearer lunar surface, allowing up to 10 Mbps down/ 1 Mbps up
