Breakthrough Proposal from Chinese Researchers for Taikonauts' Historic Lunar Touchdown

Chinese planetary scientists have unveiled a compelling recommendation for the nation's inaugural crewed moon landing, targeted before 2030. Published yesterday in the prestigious Nature Astronomy, the study spotlights the Rimae Bode region as a prime candidate site, offering a treasure trove of geological diversity ideal for advancing our understanding of the moon's volcanic past and interior evolution. This proposal comes at a pivotal moment as China accelerates its lunar ambitions, building on successes like Chang'e-6's farside sample return and gearing up for the robotic Chang'e-7 mission later this year.

The paper, led by researchers from the China University of Geosciences (CUG) in Wuhan, meticulously maps five distinct terrain types in Rimae Bode: dark pyroclastic deposits hinting at explosive volcanism 3.2 to 3.7 billion years ago, the expansive Sinus Aestuum basalt plain, sinuous rilles carved by ancient lava flows, and surrounding highlands scarred by impacts. Four specific landing zones are pinpointed, balancing safety with scientific yield—flat expanses amid varied materials perfect for rover traverses and sample collection.

This isn't just about planting a flag; it's a strategic choice to probe the moon's thermal and magmatic history, potentially revealing clues to its differentiation process where lighter crust floated over denser mantle.

China's Ambitious Roadmap to Crewed Lunar Exploration

China's manned space program, overseen by the China Manned Space Agency (CMSA), has evolved rapidly since Yang Liwei's historic Shenzhou-5 flight in 2003. Today, with Tiangong space station operational, the focus shifts to the moon. Key milestones include the Long March 10 super-heavy rocket's debut flights, the Mengzhou crew capsule (capacity up to seven astronauts), and the Lanyue lander for surface operations.

Timeline highlights: Mengzhou-1 uncrewed test in 2026, Lanyue prototypes 2027-2028, joint orbital rendezvous demo 2028-2029, culminating in taikonauts—China's term for astronauts—stepping on lunar soil before 2030. Two crew members would descend via Lanyue, while others orbit in Mengzhou, enabling a short stay with rover support. This phased approach mirrors NASA's Apollo but leverages decades of robotic precursors like Chang'e-5's near-side samples and Chang'e-6's farside haul.

Behind the hardware, universities play a starring role. CUG Wuhan's Planetary Science Institute, directed by luminaries like Long Xiao, has contributed to site selections for prior missions, analyzing remote sensing data from orbiters like Lunar Reconnaissance Orbiter (LRO) and China's own Chang'e series.

Unpacking the Geology of Rimae Bode: A Lunar 'Geological Museum'

Rimae Bode, nestled in Oceanus Procellarum on the moon's near side (around 10°N, 2°E), spans about 200 km. Orbital data from LRO's Narrow Angle Camera, Wide Angle Camera, Diviner radiometer, and Mini-RF radar reveal its layered history. Pyroclastic vents spewed dark glass beads billions of years ago, overlaying mare basalts from effusive floods and flanked by graben rilles—collapsed lava tubes up to 100 km long.

Crater counting dates events: basalts ~3.5 billion years old, pyroclastics younger at 3.2 Ga. Highlands host thorium-rich KREEP (potassium-rare earth elements-phosphorus) materials from ancient crust, ejected by impacts. Thickness maps show basalts 10-30m deep, pyroclastics thinner, ensuring accessible sampling without deep drilling.

Four sites (A-D) are flagged: Site A near rille heads for vent access, Site B on basalt-pyroclastic boundary, Site C amid rilles for structural insights, Site D in highlands for ejecta. All offer >95% safe slopes (<15°), constant Earth visibility for comms, and solar illumination potential.

• Volcanic vents: Probe explosive magmatism rare on moon.
• Rilles: Study lava rheology, cooling dynamics.
• Basalts: Age mantle overturn post-SPA basin impact.
• Highlands: Trace KREEP distribution, volatile history.

Why Rimae Bode Over the Buzzworthy Lunar South Pole?

While NASA's Artemis eyes Shackleton Crater rim for perpetual sunlight and water ice—vital for sustained presence—China prioritizes geology for its debut landing. Rimae Bode avoids south pole's rugged terrain (slopes >30° common), extreme shadows, and comms blackouts, easing engineering risks for first taikonaut steps.

South pole hosts Chang'e-7 (2026) for ice prospecting near de Gerlache or Shackleton, feeding International Lunar Research Station (ILRS) with Russia by 2035. Crewed mission focuses science return: Rimae Bode's 'museum' spans lunar epochs, contrasting south pole's resource focus. Yet overlap exists—both programs value volatiles; future ILRS may integrate sites.

Expert Jun Huang notes: "Rimae Bode's diversity maximizes knowledge gain with minimal risk." This balanced strategy positions China competitively against Artemis III (slipped to 2027+).
