Every commercial and national vehicle currently flying, building, or planned — sourced from agency and operator filings.
Athena
Site: Mons Mouton plateau, lunar south pole (~400 m off target)
Soft-landed but tipped onto its side after altimeter failure caused the lander to strike a plateau and skid into a crater rim. Power depleted within ~24 hours; ~250 MB of data transmitted including TRIDENT drill range-of-motion demonstration.
Ghost Riders in the Sky
Site: Mare Crisium near Mons Latreille (lunar near side)
First fully successful commercial soft landing on the Moon (upright, full mission). Operated 346 hours (~14.4 lunar days of daylight + post-sunset science) before battery depletion. Awarded the 2025 Collier Trophy.
Site: Apollo crater, South Pole-Aitken Basin (lunar far side)
First-ever sample return from the lunar far side and the South Pole-Aitken Basin. Used the Queqiao-2 relay satellite for far-side comms. Samples revealed unexpectedly cohesive grain behavior and excavated material from the Moon's mantle.
Odysseus
Site: Malapert A crater, ~300 km from lunar south pole
First US Moon landing since Apollo 17 and first commercial soft landing in history. Lander tipped to ~30° on touchdown after landing-leg failure but transmitted data for ~7 days before sunset.
Smart Lander for Investigating Moon ('Moon Sniper')
Site: Near Shioli crater, Mare Nectaris (~10 m precision vs 100 m target)
First Japanese soft landing; made Japan the 5th nation to soft-land on the Moon. One of two main engines failed at ~50 m altitude; lander touched down on its side but still met 100-m precision goal. Survived four lunar-night cycles despite not being designed for it; declared concluded 2024-08-23.
Chandrayaan-3
Site: Statio Shiv Shakti, 69.37°S — first soft landing near lunar south pole
First soft landing near the lunar south pole and first lunar landing by ISRO. Pragyan rover traversed ~100 m over 10 lunar days, confirmed sulfur, aluminium, calcium, iron, chromium, titanium, manganese, silicon, oxygen at the landing site. Lander 'hopped' to a secondary location demonstrating reusable propulsion.
Site: Lunar south pole region (specific site TBD)
Europe's first dedicated lunar lander program. Designed to deliver cargo, infrastructure, and surface assets supporting Artemis-era operations. Argonaut Mission 1 demonstration NET 2030; first operational mission ArgoNET in 2031.
Lunar Polar Exploration Mission
Site: Lunar south pole (permanently shadowed crater margin)
Joint ISRO-JAXA water-ice prospecting mission, designated Chandrayaan-5 by India. India's cabinet approved Phase A on 2025-03-10. Launches on JAXA's H3. Carries American and European instruments alongside Indian and Japanese ones.
Site: Near Mons Mouton, lunar south pole
India's first lunar sample-return mission. Five modules launched on two LVM3 vehicles; requires both Earth-orbit and lunar-orbit docking — first-time capabilities for ISRO. Architecture sanctioned by Government of India September 2024.
Top-down projection of the lunar south pole with major PSR-bearing craters and every tracked south-polar landing site. Coordinates from agency landing-site declarations and USGS lunar quadrangles.
Projection: azimuthal equidistant centered on 90°S, edge at 70°S. Non-polar landings (Mare Crisium, Reiner Gamma, Schrödinger Basin on the far side) are intentionally omitted; see the full lander roster for those.

Government and multi-agency programs shaping the next decade of lunar exploration, each with funding, contractors, and catalysts.
NASA's flagship program to return humans to the Moon and establish sustained lunar presence, Artemis has already flown its first crewed mission (Artemis II, April 2026) and targets the first crewed lunar landing no earlier than early 2028 [1][2]. With over $26B in government-held property spread across six prime programmes and commercial landers from both SpaceX and Blue Origin under contract, it is the largest government-sponsored space endeavour since Apollo [4].
Read program brief →CLPS is NASA's $2.6B indefinite-delivery / indefinite-quantity (IDIQ) vendor catalog that buys robotic lunar deliveries from a pre-qualified pool of 14 U.S. commercial landers — turning the Moon into a pay-per-delivery market rather than a flagship cost-plus program [1][2]. After Astrobotic's Peregrine failure (Jan 2024) and Intuitive Machines' historic IM-1 landing (Feb 22, 2024 — the first U.S. soft landing in 52 years, albeit tipped over), Firefly Aerospace's Blue Ghost 1 returned the first fully successful upright commercial landing on March 2, 2025, proving the model and unlocking a multi-year task-order pipeline through IM-3, IM-4 and Blue Ghost 2 [3][4][5][6].
Read program brief →The first crewed outpost to orbit the Moon, Gateway is a multinational small space station in a near-rectilinear halo orbit (NRHO) that will serve as a staging point for Artemis lunar surface missions [1]. Underpinned by formal partnerships with ESA, JAXA, CSA and the UAE, and with PPE + HALO co-launching no-earlier-than December 2027, Gateway commits over $5B in NASA prime contracts plus billions more in international barter for HLS rendezvous, lunar science, and sustained lunar presence [2][3].
Read program brief →Chang'e 7 is CNSA's flagship 2026 lunar south-pole reconnaissance mission, a four-vehicle stack — relay orbiter, main orbiter, lander, rover and the world-first 'mini flying detector' hop probe — designed to survey permanently-shadowed crater interiors for water ice and define the landing-site envelope for the crewed China Manned Lunar Program targeting 2030 [1][2][3]. It is the critical scientific precursor to Chang'e 8 (2028 resource-utilisation demo) and the International Lunar Research Station (ILRS) operational by ~2035, and it carries the first international payloads from Egypt, Pakistan, Bahrain, Italy, Switzerland, Russia and Thailand under the CNSA-led ILRS partnership [4][5].
Read program brief →Chang'e (嫦娥) is China's flagship robotic lunar exploration series — from the Chang'e-1 orbiter (2007) to the Chang'e-6 far-side sample return (June 2024, a world first), with Chang'e-7 polar reconnaissance (2026) and Chang'e-8 ISRU demonstrator (2028) forming the precursor architecture for the International Lunar Research Station and the Chinese crewed lunar landing by 2030 [1][2][3]. Executed by CASC's lunar systems group, the programme has delivered six of six planned mission successes and has unilaterally extended China's lunar science lead on far-side and south-polar exploration over Western peers [4].
Read program brief →ILRS is the China-Russia–led international lunar base initiative, announced jointly by CNSA and Roscosmos in a March 9, 2021 memorandum of understanding and progressively expanded to include 13+ partner countries and 10+ international research organisations (Pakistan, Venezuela, Belarus, South Africa, Senegal, Egypt, Azerbaijan, Nicaragua, Thailand, Serbia, Kazakhstan, the Asia-Pacific Space Cooperation Organisation, the International Lunar Observatory Association, and others) [1][2][3]. Robotic phase (2026-2035) is built around Chang'e-6 / -7 / -8 and Russian Luna missions; crewed phase (post-2035) leverages China's 2030 crewed lunar landing programme; positioned as a multilateral counterweight to NASA Artemis Accords (67 nations as of May 2026) [4][5].
Read program brief →Chandrayaan is India's lunar exploration series spanning four flagship missions — from the 2008 Chandrayaan-1 orbiter that first demonstrated lunar surface water signatures via NASA's Moon Mineralogy Mapper, through the 2023 Chandrayaan-3 south-polar soft landing at Shiv Shakti Point (the first ever near the lunar south pole) at a mission cost of Rs 615 crore (~$75M), to the Cabinet-approved Chandrayaan-4 sample-return mission and the JAXA-partnered LUPEX rover targeting polar volatile ice [1][2][3][4]. The series anchors a sustained Indian lunar industrial base across HAL, L&T, BEL and Godrej Aerospace at price-per-mission roughly an order of magnitude below NASA / CNSA equivalents.
Read program brief →LUPEX is the JAXA-ISRO joint lunar south-pole rover mission targeting in-situ characterisation of water ice and other volatiles in permanently shadowed regions — JAXA supplies the launch vehicle (H3) and the ~350 kg pressurised rover, ISRO supplies the lander platform, and the combined stack is the most heavily-instrumented rover ever sent to the lunar south pole [1][2][3]. Targeted for the late-2027 launch window, LUPEX is the scientific bridge between Chandrayaan-3's south-polar soft landing and the eventual ILRS / Artemis crewed campaigns and the centrepiece of Japan's $4-5B 2020s-decade lunar envelope under JAXA's Space Exploration Innovation Hub [1][6].
Read program brief →SLIM (Smart Lander for Investigating Moon) made Japan the fifth nation to soft-land on the Moon on January 19, 2024 — and the first to demonstrate sub-100-metre pinpoint landing accuracy, achieving roughly 55 metres from its target point near the Shioli crater [1][2]. With a mission cost of approximately ¥18B (~$120M) and follow-on collaborations spanning the Toyota-led Lunar Cruiser pressurised rover for NASA Artemis and the ISRO-JAXA LUPEX polar mission, JAXA's lunar architecture anchors a Japanese lunar industrial base across Mitsubishi Heavy Industries, NEC, Toyota and ispace [3][4][5].
Read program brief →The modern Luna programme is Roscosmos's attempt to revive Soviet-era lunar exploration after a 47-year operational gap. Luna-25 — the first Russian lunar mission since Luna-24 in 1976 — launched on Soyuz-2.1b on August 10, 2023 but crashed into the lunar surface on August 19, 2023 after an impulse from its propulsion system became uncontrolled during pre-landing orbital correction [1][2]. Roscosmos's recovery roadmap targets Luna-26 (polar orbiter) no earlier than 2027, Luna-27 (south-polar lander) no earlier than 2028 and Luna-28 (sample return) no earlier than 2030, all amid materially constrained post-2022 budgets and a deepened cooperation framework with China's International Lunar Research Station (ILRS) [3][4].

What the Moon actually contains — and what it doesn't. Every claim here carries a credible skeptic counter-argument from primary literature, so you can size opportunity without sizing hype.
Location: Mare regolith (high ilmenite, FeTiO₃, content) preferred; ~45% of all lunar regolith by mass is oxygen
By mass, ~45% of lunar regolith is oxygen, locked into oxides. Three production pathways: (1) hydrogen reduction of ilmenite (1-2% yield, simplest), (2) molten regolith electrolysis (Helios), (3) FFC-Cambridge molten-salt electrolysis (high yield, low efficiency). Oxygen is propellant (LOX) and life support. Israeli startup Helios + ICON + NASA Glenn all developing systems.
Skeptic's view
Note: MOXIE (oxygen demonstrator on Mars Perseverance) does NOT apply to the Moon — it splits CO₂ from Martian atmosphere. Lunar O₂ ISRU is harder: no atmosphere, energy-intensive solid-state chemistry, requires sustained power (which is itself a separate ISRU problem). No flight demonstration yet at lunar surface as of May 2026.
Location: Ubiquitous across the lunar surface; depths typically 2-15 m
The Moon's structural building material. ICON's Project Olympus is developing Laser Vitreous Multi-material Transformation — high-powered lasers melt regolith into ceramic-like structures suitable for landing pads, radiation shields, and habitat shells. NASA awarded ICON a $57.2M contract for the technology. Demonstration mission targeted for 2026-2027 at the lunar south pole.
Skeptic's view
Sintering and 3D-printing demos at Earth gravity tell us little about lunar gravity (1/6 g) and vacuum behavior. Regolith dust is electrostatically charged, mechanically abrasive, and a known degradation risk for seals, optics, and crew lungs (per Apollo crew reports). ICON's Olympus demo NET 2026-2027 will be first in-situ proof.
Location: Shackleton crater rim, de Gerlanche-Shackleton connecting ridge, and select southern polar high-ground sites
High-elevation rim sites at the lunar south pole that receive near-continuous solar illumination because the Moon's axial tilt is only 1.54°. NASA's draft architecture for the Artemis Base Camp anticipates power towers at these sites to feed PSR-interior ISRU plants and crew habitat via cable. Shackleton rim points have been mapped to ~94% annual illumination.
Skeptic's view
'Peak of eternal light' is misleading — nowhere on the Moon is 100% illuminated. Footprints of near-constant-light sites are small (square-meter scale), creating a 'lunar Manhattan' real-estate problem if multiple actors target the same rim points. The 6-8% shadow time still requires backup power (batteries or nuclear). Outer Space Treaty doesn't allocate exclusive site use.
Location: Permanently shadowed regions (PSRs) at the lunar south pole — Cabeus, Shackleton, Faustini, Haworth, Shoemaker craters
Highest-value lunar volatile. Confirmed by NASA LCROSS impact (Cabeus crater, October 9 2009) and surface mapping by ISRO Chandrayaan-1's Moon Mineralogy Mapper (M3). Targeted by Chandrayaan-3 (Vikram landing 23 August 2023, 69°S), IM-2 PRIME-1 (March 2025), Chang'e 7 (2026 NET), and LUPEX (2028 NET). Water becomes propellant (LH2/LOX) and life support.
Skeptic's view
Surficial ice is patchy and of low abundance; LCROSS measured one impact at one site. Subsurface concentrations and geotechnical accessibility remain unknown — PRIME-1 attempted to drill on IM-2 in March 2025 but landed sideways. Cabeus is at -157°C, requiring power-hungry thermal extraction.
Location: Globally distributed in surface regolith; higher concentrations in mature regolith on the lunar maria
Solar-wind-implanted isotope unique to airless bodies. Theoretical fusion fuel that produces no neutrons (clean aneutronic fusion). Interlune (US) and others have raised funds on the thesis. Current applications: medical imaging (MRI), neutron detection, cryogenics — all served adequately by Earth-sourced ³He from tritium decay or natural-gas fields.
Skeptic's view
No commercial fusion reactor exists. D-³He fusion has higher ignition temperature than D-T fusion, and D-T fusion has not yet achieved commercial breakeven. At 4 ppb average concentration, extracting 1 kg of ³He requires processing ~250,000 tonnes of regolith. Earth-side ³He from tritium decay costs ~$20M/kg today — substantial but not 'unobtainable.' SpaceNews has called helium-3 marketing 'separating market from marketing.'
Location: Mare basalt regions, especially Mare Tranquillitatis (high-Ti basalts) — ilmenite (FeTiO₃) concentrations up to ~15% by mass
Co-product of oxygen extraction from ilmenite. Iron is structural; titanium is for high-temperature applications. Theoretical use case: in-situ habitat fabrication or local manufacturing for further lunar/Mars infrastructure. Mare Tranquillitatis is high-Ti; Apollo 11 + Apollo 17 returned ilmenite-rich samples. Apollo 17 Camelot crater is a candidate ISRU site.
Skeptic's view
Lunar iron is for *in-space* use only — terrestrial iron costs ~$0.10/kg; lunar delivery costs are 5+ orders of magnitude higher. Even in-space, fabrication infrastructure (foundries, rolling mills, welding) does not yet exist on the Moon. Iron is a byproduct of O₂ ISRU, not a primary driver.
Location: Marius Hills pit (confirmed); other suspected pits at Mare Tranquillitatis, Mare Ingenii, Mare Smythii; Moon-wide candidates from skylight surveys
Hardened lava tubes from ancient volcanic flows — naturally shielded from radiation, micrometeoroids, and thermal extremes. Surface temperatures swing 127°C (sunlit) to -173°C (shadow); a few meters underground, temperatures stabilize at ~-20°C. Considered NASA's strongest candidate for long-duration crewed habitats. ESA's BR-LRD-CONOPS programme evaluates lava-tube descent architectures.
Skeptic's view
Detected but unexplored — interior dimensions, structural integrity, dust, electrostatic charging, and atmospheric composition (radon? volatiles?) are all unknown. Surface access via 50-100 m vertical skylight drop requires landing and rappelling technologies not yet demonstrated. Marius Hills is far from south pole resources and Earth-line-of-sight comms.
Location: Procellarum KREEP Terrane (PKT) on lunar near side, especially Oceanus Procellarum and Mare Imbrium ejecta
Acronym for Potassium (K), Rare-Earth Elements, Phosphorus — geochemically anomalous material concentrated in the last lunar magma ocean fraction to crystallize. Source of lunar thorium + uranium signatures detectable from orbit. Of long-term interest for in-situ fission fuel + plant-growth nutrient potassium/phosphorus, not for Earth export.
Skeptic's view
Lunar REE enrichment is *relative* to other lunar regions — absolute concentrations are still parts-per-million scale and lower than terrestrial REE ores. China and Australia produce REEs at $10-100/kg ranges; even speculative lunar prices are $1,000+/kg delivered to Earth. Economic viability requires either: (a) in-space utilization (no transit cost), or (b) a global REE export ban from Earth producers. Neither is imminent.
