Week in Space Data, every Friday.
Space mining is the extraction of valuable resources from celestial bodies: asteroids, the Moon, Mars, and other planets or moons. These resources include water ice (for propellant and life support), metals (for construction), precious metals (for high-value export), and exotic materials (for advanced technology).
The space mining market is projected to grow significantly as cislunar infrastructure develops. The first commercially viable space mining operations are expected to focus on lunar water ice, which can be converted into rocket propellant, creating a "gas station in space" that dramatically reduces the cost of deep space missions.
Where: Moon, Mars, asteroids
Value: Rocket propellant, life support
Status: NASA CLPS landers surveying ice deposits
Where: Metallic asteroids
Value: Catalysts, electronics
Status: AstroForge has flown demonstration spacecraft; no extraction yet
Where: Asteroids, Mars
Value: In-space construction
Status: Future: requires orbital manufacturing
Where: Lunar regolith
Value: Proposed fusion fuel; also used in cryogenics and neutron detection
Status: Depends on helium-3 fusion, which has not been demonstrated at power-plant scale
Where: Titan (Saturn moon)
Value: Chemical feedstock, fuel
Status: Far future: requires Titan missions
Where: Asteroids
Value: Electronics, sensors, advanced tech
Status: Long-term target for in-space demand
Yes. The 2015 US Commercial Space Launch Competitiveness Act grants US companies the right to own and sell resources extracted from asteroids and other celestial bodies. The Artemis Accords (signed by 78 nations as of October 2026) support this principle.
Water ice (from the Moon and Mars), platinum group metals and gold (from asteroids), iron, nickel, and titanium (from asteroids and Mars), Helium-3 (from lunar regolith for fusion fuel), and methane/ethane (from Titan).
AstroForge (asteroid mining), TransAstra (optical mining), ispace (lunar resources), Intuitive Machines (lunar landers for resource prospecting), and Offworld (robotic mining). Commercial CLPS landers carry ice-prospecting payloads, such as NASA's PRIME-1 drill on IM-2 (March 2025). NASA's Lunar Trailblazer orbiter, meant to map lunar water, lost contact the day after its February 2025 launch; the mission ended in July 2025 (JPL). The VIPER rover was canceled in 2024 over cost overruns; in September 2025 NASA ordered a conditional delivery on a Blue Origin Blue Moon Mk1 lander, with the delivery option decided only after Mk1's first flight (NASA).
Headline figures such as "$10,000 quadrillion" for the metal asteroid 16 Psyche are back-of-envelope multiplications of estimated mass by terrestrial commodity prices, not valuations: nobody can mine or return that much material, and bringing even a fraction to Earth would move the prices it is based on. Real economic value depends on demand in space, such as water for propellant.
Nobody knows, and no company has yet extracted and sold a space resource. NASA's Artemis plans and the CLPS lander missions are prospecting for lunar water ice first; asteroid mining companies are still flying demonstration spacecraft. Treat any year attached to commercial space mining as a forecast, not a schedule.
In-Situ Resource Utilization (ISRU) means using materials found at the destination rather than bringing everything from Earth. For example, extracting water from lunar ice and splitting it into hydrogen and oxygen for rocket fuel. ISRU is critical for affordable deep space exploration.
