NASA Names New Possible Artemis Landing Sites, Reduces Choices from 13 to 9

NASA updated landing sites for Artemis III in heavily cratered, mountainous Lunar South Pole region; #1 consideration is Astronaut safety, then science potential, launch window, surface, seismic stability, Earth communication, lighting, combined capabilities of rocket / Orion spacecraft / SpaceX Starship Human Landing System; each location available for only part of 6-day mission so flexibility critical; permanently shadowed South Pole areas can preserve water; NASA will hold conferences / workshops to gather data; Malapert Massif ~5,000 m has perpetual sunlight, descends ~8,000 m into permanently shadowed regions; Mons Mouton Plateau wide / flat, 5,000-6,000 m, has perpetual sunlight

First Lunar Far Side Sample Return Mission on Route to South Pole-Aitken Basin

China space agency CNSA guiding Chang’E-6 53-day mission, consisting of 4-module stack launched from Wenchang SLC (19 N°) on LM-5 rocket 3 May and Queqiao-2 relay satellite, also launched from Wenchang on LM-8 and currently in 200 x 16,000-km lunar orbit; Lander, ascender orbiter and return capsule to reach Moon orbit by 8 May, where they will remain for ~20 days before lander and ascender separate and descend to 490-km Apollo crater (itself within 2,400-km Aitken Basin) spending 48 hours drilling to a depth of 2-m and retrieving up to 2-kg of regolith for Earth (Inner Mongolia) return 25 June

Japan SLIM Moon Lander Defies Expectations by Operating on 4th Lunar Day

JAXA controllers maintaining delicate balance on operational period which began 23 April, timing command / transmission with day-long interval to avoid overheating amid temperatures exceeding 100°C; Reactivation following 3rd lunar night (with temps near -170°C) was earlier in lunar day than previous cycles, resulting in brightest landscape / shortest shadows imaged during mission thus far; Near-equatorial location (13.3160°S, 25.2510°E) of SLIM lander mitigates temperature flux in comparison to near-polar site of Intuitive Machines Odysseus, which functioned 1 lunar day; Both Odysseus and SLIM contain lithium-ion batteries, however SLIM utilizes bespoke pouch cells, whereas Odysseus has COTS cells

NASA Reportedly Considering Major Change to Mission Design of US$93B Artemis Program

Artemis 3 could be modified to test Orion-Starship docking and habitability in LEO or perform Gateway rendezvous in lunar orbit rather than a full-fledged human surface landing as originally envisioned, per Ars Technica report citing anonymous sources; ‘NASA continues to work toward… Artemis III test flight to land astronauts near the lunar South Pole in September of 2026’ per official response; Hardware challenges include Orion heat shield modification, spacesuit and lander development; Operational complexity including first in-space cryogenic refueling likely also contributing to reassessment

NASA Tasked with Development of Lunar Time Standard NLT 31 Dec 2026

As Moon mission cadence continues to grow, and in recognition of gravity-induced spacetime dilation resulting in 58.7-μs offset from Earth, White House Office of Science and Technology Policy is directing NASA (with Commerce, Defense, State, Transportation departments) to define and implement time reference frames for non-Earth celestial bodies, beginning with Coordinated Lunar Time (LTC) in support of Moon surface and cislunar activity; Elements to be considered by National Cislunar Science & Technology sub-Interagency Working Group (NASA + National Space Council) include: Traceability to UTC, Accuracy for PNT, Resilience when out of Earth contact, and Scalability for bodies beyond Earth-Moon system

SLIM Awakens for 3rd Lunar Day of Operations

JAXA team working at Sagamihara Campus SLIM control room are ebullient as their 2.4-m tall lunar lander reactivates yet again, enduring 2 cold nights on the Moon with temperatures below -130°C at mid-latitude landing site (-13.3160°, 25.2510°); Landscape imagery being taken via navigation camera currently amid high temperatures near 100°C with Sun relatively high overhead (necessary to power solar panels in off-nominal orientation); JAXA reports systems are mostly functioning aside from some temperature sensors and battery cells; Lunar day ends for SLIM on 30 March; SLIM team to present at Tanegashima Space Center open house 21 April

Strong Focus on Malapert Mountain at 2024 LPSC Reflects Growing Interest in Strategic Lunar Area

Numerous researchers have converged to analyze the structure, content and relative advantages of landing human and robotic mission on Malapert Massif as highlighted by studies presented at the 55th Lunar and Planetary Science Conference held in The Woodlands, Texas; Geological EVA Science Among Impact Craters and Permanently Shadowed Regions Near a Summit Ridge on Malapert Massif proposes 3 EVA traverses emanating from 85.964°S, 357.681°E landing site to collect samples from 50-35K regolith; High Resolution Geomorphic Map provides detailed crater morphology / PSR locations; Hazard Mapping of the Southern Lunar Surface: Candidate Artemis Landing Site notes maximum average temp of 193.3K / minimum 46.4K

SLIM Awakens, Resumes Mission to Characterize Lunar Surface

The motorcycle-sized SLIM lunar lander is collecting solar energy and conducting spectral analysis of regolith near 13.3160° S, 25.2510° E landing site after 10 days of uncertainty following off-nominal descent caused by loss of 1 (of 2) 500 N main engine resulting in a flipped landing orientation requiring westward sun; Despite this adversity, SLIM did achieve 1.4 m/s soft-landing within ~55 m of precision targeted site and is set to continue collecting data until end of lunar day, ~31 Jan UTC (began ~16 Jan) within 10 spectral bands via Multiband Spectroscopic Camera (MBC); Landscape image (L) generated by completing 257 low-res images reveals first light including protuberance dubbed ‘toy poodle’
