Space Mining & Resources

Laser vaporization (AstroForge) uses high-power lasers to heat and decompose asteroid material for mineral extraction and separation. Capture Bag technology (TransAstra) encloses small asteroids in inflatable containers for material processing in microgravity. TRIDENT drill (NASA PRIME-1) excavates lunar regolith to 3 feet depth for water ice detection using mass spectrometry. Autonomous navigation and anchoring systems enable spacecraft to approach, orbit, and attach to small, irregularly shaped asteroids. Electrolysis separates water ice into hydrogen and oxygen for rocket fuel and life support. Solar concentrators focus sunlight to heat regolith for volatile extraction, metal reduction, or 3D printing feedstock creation.

AstroForge's Odin mission represents the first commercial attempt to reach a mining-target asteroid, testing laser vaporization extraction technology at $3.5 million mission cost. NASA's PRIME-1 on IM-2 drilled up to 3 feet into lunar south pole regolith to detect and analyze water ice and volatiles. China's Tianwen-2 will autonomously navigate to, anchor on, and collect samples from near-Earth asteroid Kamoʻoalewa for Earth return. TransAstra's Capture Bag technology demonstration on ISS tests the approach of enclosing asteroid material in inflatable containers. Solar concentrators in NASA ISRU programs demonstrate oxygen extraction from lunar regolith through thermal processing.

The space mining market reached $2.4-4.0 billion at 19.2-24.4% CAGR to $7.0-21.6 billion by 2030-2033. Asteroid mining reached $1.7-4.0 billion at 21.8-23.6% CAGR. Asteroid prospecting micro-probes represent $1.96 billion through 2035. AstroForge's Odin mission cost $3.5 million. NASA's PRIME-1 payload weighed 40 kg. China's Tianwen-2 targets asteroid sample return by late 2027.
