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

NASA Soliciting Thoughts on Landing Site Value and Non-Interference in Lunar Operations

Expanding on Artemis Accords Section 11 (Deconfliction of Space Activities), which evokes legal concepts such as ‘due regard’ and ‘safety zones’ in consideration of activity on the Moon with potential to interfere in the activities of another signatory, NASA Office of Technology, Policy, and Strategy (OTPS) seeking guidance on landing site valuation (with special emphasis on MSP), how such value may degrade with contamination and mitigation measures; Secure World Foundation, Moon Village Association, For All Moonkind, Open Lunar Foundation among stakeholder groups working to formulate lunar policy; Questionnaire due 7 June 2024

NASA OIG Identifies Needed Orion Improvements Ahead of Crewed Artemis 2 Mission

Report NASA’s Readiness for the Artemis 2 Crewed Mission to Lunar Orbit recommends significant review of Orion spacecraft systems prior to integration and stacking of the Lockheed-Martin / Airbus-built capsule on Artemis SLS rocket for NET Sept 2025 launch of Artemis 2, in light of Artemis 1 anomalies including 100+ areas of unexpected heat shield degradation during reentry, melting of separation bolts, and 4.5-hour communication outage; NASA plans to increase material between separation bolts before Artemis 3 redesign and upgrade DSN servers to prevent a reoccurrence of Goldstone outage, considering modification to less strenuous reentry trajectory

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

Intuitive Machines Well Positioned to Capitalize on Growing Cislunar Economy

Predicting US$250M revenue in 2024 and estimating $70M cash on hand, market analyst Stephen Tobin makes bullish case for Houston TX-based Intuitive Machines (LUNR) despite $53M negative equity as of Q4 2023 earnings report; Pointing to success of IM-1 and upcoming NASA CLPS-funded IM-2 and -3 missions NET Q4 2024 / 2025 as well as $30M Lunar Terrain Vehicle (with Boeing, Northrop Grumman), $719M Joint Polar Satellite System (with KBR), and $5M Fission Surface Power (with X-energy) contracts, Tobin suggests IM lunar services will be in demand by commercial interests and small national space agencies eager to utilize Earth-Moon / cislunar transport, operational and communication capabilities

Japan Pioneers Lunar Broadcasting with First Amateur Radio Station on Moon

JAXA Ham Radio Club (call sign JQ1ZVI) has established radio communication in 437.41 MHz frequency with 1 W UHF transmitter weighing just 90 g aboard Lunar Excursion Vehicle (LEV-1) hopper (2.2 kg total mass), deployed from JAXA SLIM lander during 19 Jan UTC (20 Jan JST) landing descent; Signal containing Morse Code received by operators around Earth from a distance of ~380,000 km, including C.A. Muller Radio Astronomy Station utilizing 25 m radio telescope at Dwingeloo NL; SLIM is currently dormant as lunar night transpires but JAXA operators will attempt reactivation upon lunar daybreak in mid-Feb
