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

S Somanath of ISRO Continues Visionary Leadership for India Moon / Space Exploration

Dr. Sreedhara Panicker Somanath, Chairman, Indian Space Research Organisation (ISRO) since January 2022, has clear vision of India in the forefront of exploration beginning with Moon, oversaw Chandrayaan-3 Statio Shiv Shakti landing near 70° South; focuses on Space Vision-2047 missions including Gaganyaan, Chandrayaan-series, others, Bharatiya Antariksha Station development, humans to Moon by 2040; plans Chandrayaan-4 sample return mission of 2-5 kg from lunar South pole to enhance understanding of Earth-Moon System origin; posits that ISRO aims for the stars but “will not forget the farmer or fisherman while exploring the Solar System,” emphasizes space technology must improve life on Earth

Moonquake Mitigation Being Examined for Upcoming 21st-Century Human Landings

Moonquakes can last hours, earthquakes seconds; Astronauts left lunar seismometers 50 years ago showing South Pole-region epicenters likely due to global shrinkage from core cooling; University of Texas researchers used JAXA funding to decipher Moon seismograph data; 7 researchers, T.R. Watters, et al, published 25 January 2024 in Planetary Science Journal that Malapert Massif / other proposed Artemis landing sites not landslide-threatened, but structures / materials / gravity need to accommodate shaking / quivering / trembling say San Francisco engineering firm / American Society of Civil Engineering under a NASA grant

ispace Projects Significant Demand of Lunar Services, ISRO Targeting Shiv Shakti with Chandrayaan-4

Japan first commercial lunar lander company ispace projecting 138% increase in year-on-year net sales, growing to JPY¥4,033M (US$25.8M) in FY2024 possibly buoyed by international orders for lunar landers and robots, especially from USA, which may mitigate expected JPY¥12,465M ($79.8M) loss, with ispace CEO Takeshi Hakamada (R) characterizing business environment as ‘quite positive‘ in light of USA-Japan Artemis agreement; Nilesh Desai, director of Space Applications Centre (SAC) in Ahmedabad, declares Shiv Shakti point (Statio Shiv Shakti by IAU designation, 69.373°S, 32.319°E) will be destination of Chandrayaan-4, building on successful Chandrayaan-3 mission, possibly returning sample closer to MSP than any previous NET 2028

Commercial USA IM-1 Lander Odysseus on Direct Course for Moon

Intuitive Machines of Houston TX working around the clock to achieve first USA Moon landing in 21st century and first commercial landing ever with Nova-C ‘Odie’ on Trans-Lunar Orbit (TLO); Odie is expected to archive Lunar Orbit Insertion (LOI) on 21 Feb, followed by landing site near the eastern rim of Malapert A crater (80.2°S, 1.0°E) 22 Feb; Carrying 6 NASA and 6 independent payloads under $118M NASA CLPS contract + undisclosed private freight charges, the IM-1 mission was inspired by Space Policy Directive-1 per CEO Steve Altemus; SPD-1 calls for public-private and international partnerships to ‘enable human expansion across the solar system’

India Planning Next Lunar Missions as Chandrayaan-3 Data Being Analyzed

As ISRO awaits the possible reactivation of Chandryaaan-3 Vikram lander and /or Pragyan rover, scientists are just beginning the task of working with data delivered over the course of the 14-Earth day nominal mission including first in-situ evidence of sulphur observed by Laser-Induced Breakdown Spectroscope (LIBS) and Alpha Particle X-ray Spectroscope (APXS), first recorded Moonquake since Apollo with Lunar Seismic Activity (ILSA) and findings of sparse ionosphere of 5,000,000 – 30,000,000 electrons per meter2; ISRO expected to collaborate with JAXA on LUPEX polar mission NET 2025, and may announce Chandrayaan-4, Chandrayaan-5 timelines soon per Chandrayaan-1 mission director Mylswamy Annadurai

JAXA Counting Down to Launch of Smart Lander for Investigating Moon (SLIM)

SLIM set to lift off on H-2A rocket with XRISM rideshare from Tanegashima Space Center 26 August 09:34 JST (00:34 UTC) for 4–6-month journey to landing site at 13.2°S, 25.2°E, an area east of Shioli, a 270-m diameter crater emanating distinctive bright rays (itself within 98-km Cyrillus crater, west of Mare Nectaris); 200-kg (dry) SLIM will take fuel-efficient route to lunar orbit taking ~3-4 months, followed by ~1 month in lunar orbit prior to surface descent; Primary mission objective is validation of vision-based navigation system with <100m accuracy; JAXA will stream launch with live coverage starting 09:00 JST (00:00 UTC)

Chandrayaan-3 on Track for Mid-Year Launch, ISRO Chief Adamant on Precision Landing Near Manzinus Craters

Speaking at 3-day Indian Planetary Science Conference (IPSC) at Physical Research Laboratory in Ahmedabad attended by ~225 delegates, ISRO Chairman S Somanath identifies precision landing near 70.83°S, 22.67°E as “primary objective” of Chandrayaan-3 Moon mission, adding that science objectives will remain largely similar to those of failed Chandrayaan-2 (study and mapping of lunar resources especially hydroxyl / water ice); Somanath also indicated ISRO-JAXA joint mission dubbed ‘LUPEX’ may proceed, Shukrayaan-1 Venus mission to launch NET 2028, and “meaningful” science rational for Gaganyaan human spaceflight program must be developed
