Mars Mining Weekly Briefing, issue #1. By Mars Mining Desk.

This is a weekly read on space resources: who is trying to get water, oxygen, metals and helium-3 out of the Moon, Mars and asteroids, and whether the numbers hold up. We read the releases and check the dates. Then we tell you what we think. Expect more skepticism than cheerleading.

Here is what moved in the past seven days.

Uzbekistan becomes the 77th Artemis Accords signatory. Foreign minister Bakhtiyor Saidov signed in Samarkand on Oct. 19, per the State Department. Nobody expects Uzbek lunar mines. The point is Section 10, which says extraction is not national appropriation. Each signature adds a government on the record for the reading that makes a resource business bankable. China and Russia remain outside, and they also have south pole plans. Our take.

Interlune shows its helium-3 prospector. The company's Prospect Moon walkthrough describes three regolith scoops: one heated to 950 °C, one milled mechanically, one run through a grain sorter. Milling reportedly uses about a tenth the power of heating, so that comparison is the experiment to watch. The payload is ready in September 2027 and still has no lander. Its DOE delivery is due by April 2029. That is a tight overlap between measuring the resource and selling it. Full piece.

ESA pays to ask whether Moon mining makes money. A MIRORES-led consortium called Lunavest will model the lunar resource chain from prospecting to paying customer. Good. We'll judge it on one thing: whether ESA publishes break-even figures or keeps the model in-house. Our view.

Starship's refueling clock. SpaceX says orbital flights begin with Flight 14, with a ship-to-ship propellant transfer targeted for 2026. About ten weeks remain in the year. Every lunar cargo plan assumes refilling works at scale, and nobody has yet moved hundreds of tonnes of cryogens between two docked vehicles. We expect a slip into 2027. Why it matters.

Chang'e-7 still has no date. China scrubbed the Aug. 24 launch, and Scientific American reports a hold until at least 2027. Its hopper was meant to measure ice inside a shadowed crater. That remains the most valuable missing data point in lunar resources. More.

The flying car in the room

Tesla revealed its next-generation Roadster on Oct. 15 at SpaceX's test site in McGregor, Texas, CNBC reported, almost a decade after first taking deposits. The stunt version uses SpaceX-built cold-gas thrusters. Teslarati lists three trims, with the invite-only "Rocket" using perimeter thrusters to hop, flip and land. Car and Driver says the demo ran on two composite pressure vessels totaling 600 liters. Musk put production in 2028. Fortune reports $250,000 deposits for the thruster version and an FAA view that it is not an aircraft.

Our read: this tells you nothing about space resources. Cold gas thrusters are among the oldest tricks in spaceflight, and a car carrying a tank of compressed air is a theater prop. The real SpaceX news of the week is the boring one above, propellant transfer. The Roadster is mostly evidence of how closely the two companies now work, which CNBC ties to merger speculation. If a Tesla-SpaceX deal happens, watch whether Starship capital spending changes. That would matter to anyone planning lunar cargo.

Binge this

We reorganized the archive into five reading paths on the topics page: Space Resources 101, The Money, Rules of the Road, The Race to the South Pole, and Careers. If you read one guide, make it the helium-3 reality check. Then try asteroid mining economics, where the math is less kind than the pitch decks.

Who's hiring

Lunar and materials roles from our jobs board:

• Vast, Senior System Architect, Lunar (Long Beach)
• Vast, Senior Mechanical Engineer, Lunar (Long Beach)
• ispace, Senior Thermal Engineer (Luxembourg)
• SpaceX, Thermal Development Technician, Robotic Welding, Starship (Starbase)
• Relativity Space, Materials Characterization Specialist II, Chemistry and Powders (Long Beach)

What would change our mind about this week's mood: a named lander for Prospect Moon, or a Starship transfer measured in tens of tonnes before January. Either one would move lunar timelines more than any flying car.

See you next Thursday.
