Commercial Lunar Lander Odysseus Prepares for Correction Maneuvers Ahead of LOI

Intuitive Machines analyzing data from first in-space firing of liquid methane & liquid oxygen engine, conducted 270,000+ km from Earth, testing full (21 sec) and throttled thrust profiles and first of three trajectory corrections ahead of Lunar Orbit Insertion – the most powerful maneuver of the mission, expected to consume 1/3 of total propellant for 800-900 m/s delta-V and marking milestone 7 out of 16 company-defined IM-1 success criteria, set to be completed Feb 21 prior to Feb 22 powered descent; Landing to be streamed on IM website, time to be announced at Las Vegas Sphere event hosted by Columbia Sportswear

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

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’

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

Intuitive Machines Set to Become First Independent Operator on Moon with US$118M Mission

Nova-C class lunar lander Odysseus may make history with expected 22 Feb landing near Malapert A crater (80.2°S, 1°E), ~175 km from the peak of Malapert Massif and ~300 km from MSP; Intuitive Machines will be the fourth commercial attempt at Moon landing, following SpaceIL (Feb 2019), ispace (April 2023) and Astrobotic (Jan 2024) and the first USA landing attempt of any type in over 51 years, since Apollo 11 (Dec 1972); In addition to 5 NASA commissioned science instruments, Odysseus will carry 6 commercial payloads (clockwise): ILO-X (International Lunar Observatory Association), Lunaprise (Galactic Legacy Labs), Independence (Lonestar Data Holdings), Moon Phases (Jeff Koons, 4Space), Omni-Heat Infinity (Columbia Sportswear), and Eaglecam (Embry-Riddle)

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’

Japan Celebrates Becoming 5th Nation to Soft Land on Moon as Efforts to Extend Surface Operations Continue

JAXA has met its minimum success criteria for SLIM mission by landing softly on the lunar surface, however operations were suspended when battery level reached 12% at 02:57, Jan 20 JST (17:57 on 19 Jan UTC) just hours after landing due to attitude anomaly which left solar panels oriented westward; Prior to battery disconnection, JAXA ‘obtained a lot of data‘ and hopes to receive more if lander can be reactivated as Sun moves west toward the end of the current lunar day (~30 Jan); While not designed for lunar night survivability, ‘if the spacecraft survives the -200°F night, then in two weeks’ time, it could revive again‘ per ISAS Director General Hitoshi Kuninaka

Astrobotic Looking Forward as Intuitive Machines Prepares its Effort to Land First Commercial Mission on Moon

The first attempted USA commercial lunar lander has returned to Earth, reentering over the South Pacific with undetermined wreckage possibly resting near 23.087°S, 176.594°E ~450 km south of Kadavu (Fiji) and east of Aneityum (Vanuatu) Islands; Despite propellant leak which prevented Moon landing, “There’s a lot that worked” on Peregrine Mission 1, Astrobotic CEO John Thornton told media at joint NASA press conference, while the final mission update declares Peregrine has flown so Griffin may land; Intuitive Machines IM-1 is the next (of up to 9) scheduled CLPS missions, with Nova-C launch window set to open NET 11 Feb; CEO Steve Altemus envisions infrastructure business model “where the company plays the same role as highways, railroads, and shipping lanes are for Earth, but at the moon [sic]” per interview with Spectrum News in Orlando
