NASA Advances Moon Base with Over 20 Planned Landings
NASA is accelerating development of a sustained lunar outpost near the Moon’s South Pole through a series of commercial robotic missions. More than 20 landings are scheduled through 2029 under Phase I of the Moon Base architecture, involving partners including Blue Origin, Firefly Aerospace, Intuitive Machines, and Voyager Technologies. These flights will deliver infrastructure, test precision landing, communications, power systems, and technologies able to endure extreme lunar conditions, while also enabling science such as far-side exploration and investigation of a magnetic lunar swirl.
Background includes NASA’s Commercial Lunar Payload Services (CLPS) initiative, which aims to establish a reliable cargo supply chain ahead of human operations. Blue Origin’s Blue Moon MK1 is completing environmental testing for its Endurance mission; Firefly’s Blue Ghost Mission 2 targets the first U.S. far-side landing; Intuitive Machines’ IM-3 will deploy a data relay satellite and explore Reiner Gamma; and Voyager’s Griffin-1 is undergoing JPL environmental tests to carry a large rover payload. Northrop Grumman is adapting Gateway-derived power and avionics hardware for surface survival demonstrations.
Key uncertainties center on the reliability of commercial landers in the harsh lunar environment, coordination of multiple providers, and whether early robotic results will sufficiently de-risk later human-tended systems. Success depends on iterative learning from each flight and consistent performance of cryogenic propellants, autonomous systems, and night-survival technologies.

Silver Nanocatalysts Reveal Mode-Dependent Reaction Switch
Researchers at Seoul National University and collaborators have shown that silver nanocatalysts on solid oxide cell electrodes switch their primary reaction sites depending on operating mode. In electricity-generating (oxygen reduction) mode, activity concentrates at the silver-electrode interface; in hydrogen-producing (oxygen evolution) mode, it shifts to the silver particle surfaces themselves. The finding, published in Energy & Environmental Science, offers a route to more efficient reversible solid oxide cells for power and green hydrogen.
Background involves solid oxide cells that conduct oxygen ions at high temperature and can operate bidirectionally. Prior work established that metal nanocatalysts boost oxygen exchange rates, but the precise locations and mechanisms remained unclear due to complex electrode structures. The team used ordered model electrodes with uniform silver nanoparticles, combined with electrochemical testing, synchrotron analysis, and atomic calculations, to isolate the switch and show silver outperforms cobalt, palladium, and platinum in the tests.
Tensions include translating the model-electrode insights to practical porous electrodes and confirming durability under real cycling. Uncertainties remain about long-term stability of the site-switching behavior and how best to engineer both interfaces and surfaces simultaneously for commercial devices.

NASA Extends Voyager 2 Science Operations via Power Reconfiguration
NASA’s Jet Propulsion Laboratory has executed a “Big Bang” power-saving operation on Voyager 2, freeing enough energy to keep its three remaining science instruments running for at least another year. The nearly 50-year-old probe, powered by decaying plutonium in radioisotope thermoelectric generators that lose about 4 watts annually, faced the need to shut down another instrument by the end of 2026 without the change.
Background: Both Voyagers have progressively powered down non-essential systems and instruments as available power dwindled; two science instruments on each craft were already switched off since 2024. Engineers simultaneously disabled higher-draw components and activated lower-power alternatives while maintaining thermal conditions necessary for survival in interstellar space. The same procedure is planned for the more distant Voyager 1 in coming months.
Uncertainties involve the exact remaining lifetime of the generators, the risk of unexpected thermal or electrical issues from the reconfiguration, and how much additional science return can be extracted before further shutdowns become inevitable. The operation buys time but does not reverse the fundamental power decline.
