NASA's 70-Landing Lunar Decade Hinges on Power Infrastructure Nobody Has Built Yet

What does NASA's 70-landing target actually require on the surface?

NASA's plan for more than 70 Moon landings over the next decade is, at its core, a logistics and infrastructure challenge dressed up as an exploration cadence. The agency's Commercial Lunar Payload Services (CLPS) and Artemis program together envision sustained human presence near the lunar south pole — but every serious surface-operations architect knows the gating constraint is not rockets or landers. It is kilowatts. NASA's ambition to execute more than 70 robotic and crewed Moon landings by 2035 cannot be sustained without continuous multi-kilowatt surface power, a capability that remains at Technology Readiness Level (TRL) 4–5 at best for lunar-qualified hardware.

The lunar south pole environment makes this brutally clear. Permanently shadowed regions — the very locations that hold water ice — receive no sunlight. Peaks of eternal light nearby offer partial solar exposure, but surface photovoltaic (PV) arrays at those locations must survive temperature swings exceeding 300 °C between illuminated and shadowed terrain. Researchers at the University of Pennsylvania's Bargatin Lab are studying layered Mylar stacks as a passive thermal insulation approach for habitat structures; their work, reported in late October 2026, demonstrates that thin reflective films can reject extreme infrared heat loads. This is promising for thermal management of solar panels and power conditioning electronics, though the lab demonstrations are terrestrial and have not yet been validated in a lunar thermal-vacuum environment.

How does space-based solar power fit the lunar surface power problem?

Space-based solar power (SBSP) — the concept of collecting solar energy in orbit, converting it to microwave or laser radiation, and transmitting it to a receiver on a planetary surface or Earth — is one candidate architecture for delivering uninterrupted power to the lunar south pole, precisely because an orbiting relay is not subject to the day-night cycle that limits surface PV arrays. A recent simulation study published on arXiv models a photovoltaic array suitable for deep-space operation, testing maximum power point tracking (MPPT) performance under varying solar irradiation levels in a MATLAB/Simulink environment. The paper notes that end-to-end microwave power transmission efficiency remains a central design challenge, with system-level losses accumulating through the conversion, transmission, and rectenna stages. Simulation is TRL 1–2 work; it clarifies design trade-offs but proves nothing about on-orbit performance.

Space-based solar power, in the simplest terms, works by placing a large PV array in orbit where sunlight is available nearly continuously, converting the electricity to a directed microwave or laser beam, and receiving that beam at a rectenna or photovoltaic receiver on the ground or on a planetary surface — achieving power delivery independent of local day-night cycles.

What neither study addresses is specific power (W/kg) for the transmitting array. A lunar-relay SBSP architecture must be launched, and launch costs — even on a mature vehicle — set a hard floor on what the delivered electricity is worth. Falcon 9 is winding down its operational cadence, and the industry is bracing for a launch availability crunch as Starship human-rating and New Glenn manifest growth absorb capacity through 2027. A power-beaming relay satellite massing several tonnes would compete directly for that constrained manifest.

The radiation variable no surface power roadmap can ignore

Surface power systems on the Moon must also be designed around the radiation environment. Data from the Artemis I mission, collected via lithium fluoride (LiF) crystal thermoluminescent dosimeters placed inside two anthropomorphic phantoms aboard the Orion spacecraft, are now being analyzed — with results from the Matroshka AstroRad Radiation Experiment (MARE) published in late October 2026. Solar array degradation rates scale directly with cumulative proton and heavy-ion dose; any surface power system sizing model that does not incorporate these measured lunar transit dose values will be optimistic on array end-of-life output.

The implication for your next decision

If you are sizing a lunar surface power system, or evaluating whether a power-beaming relay satellite belongs on your Artemis-adjacent roadmap, the honest answer is that no single architecture closes today. Surface PV arrays at peaks of eternal light are closest to bankable — but thermal management, array degradation from radiation, and the 14-Earth-day shadow periods at off-peak sites all demand margin your mass budget may not accommodate. SBSP relay concepts are technically coherent but remain in simulation and sub-scale lab phases, with launch economics still structurally prohibitive absent a dramatic reduction in per-kilogram costs. The 70-landing target is a procurement signal, not a power delivery plan; the program office that tables a credible multi-kilowatt continuous-power architecture — with measured TRL, a mass budget, and a launch slot — will set the terms of the next decade of lunar operations.
