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

SpaceX Presents Plan to Use Starship as Lunar Base Construction Element

14 companies selected to develop conceptual framework for Moon commercialization under <US$1M DARPA 10-Year Lunar Architecture Capability Study (LunA-10) contracts deliver proposal briefs at Lunar Surface Innovation Consortium Spring meeting at JHU/APL, with final reports expected in June; SpaceX study envisions lunar base infrastructure established with 3 Starship landings: Utility Starship as power / communications hub, Rolling Stock Starship for rovers and construction machines, Habitation Starship for crew living quarters; Company projects Starship payload cost to lunar surface to drop from <$10,000/kg to ~$1,000/kg after 2030

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

Chandrayaan-3 Landing Site Now Officially Designated Statio Shiv Shakti by International Astronomical Union

IAU Working Group for Planetary System Nomenclature on 19 March declares area around Vikram lander between Manzinus C and Simpelius N craters (-69.37°, 32.32°) Statio Shiv Shakti (Shiva Shakti Station) after Hindu deities which symbolize masculine and feminine energies in recognition of 4th national soft-landing on Moon; Chandrayaan-1 probe impact site ‘Jawahar Point’ and Chandrayaan-2 crash site ‘Tiranga’ have also been submitted to IAU; Shiva and Shakti are also invoked by Max Planck Institute astronomers for metal-poor 12-13 billion year old stellar streams thought to be proto-galactic fragments observed by Gaia Space Observatory and Sloan Digital Sky Survey; Rubin crater between Amundsen and Demonax B crater (-82.82°, 77.65°) was also named on 19 March after the American astronomer Vera Rubin

Intuitive Machines Overcoming Obstacles While Operating in Space on Route to Moon

Nova-C class lander Odysseus is ‘in excellent health, in a stable orientation’ and on track for 22 Feb soft landing attempt ~300-km from Moon South Pole despite several trials: intermittent comms, a slight star tracker miscalibration ameliorated via software update, and variance in LOX line chill time in space vs Earth (Odysseus being only the second LCH4 / LOX craft to operate in space following LandSpace Zhuque-2 in Dec 2023) for which adjustments have been made; Commissioning Burn originally expected within first day of transit to be conducted shortly
