One launch delivers an autonomous probe and a 240-meter industrial net to any near-Earth asteroid on an inbound trajectory. We catch it, kill its spin, and mine it on the way home.
The capture web is a paraboloid mesh of UHMWPE and braided steel, tensioned by twelve drawstring winches at the rim. Closure takes 8.2 seconds from contact. The probe bus provides de-spin authority, solar power, and the return burn.
Rideshare launch → phasing cruise → rendezvous at 1.2 km → net deployment → capture & de-spin → trajectory bend to cislunar depot → in-transit beneficiation → ore handover in high lunar orbit.

Pierce set the capture-vehicle architecture and the thesis behind it: the cheapest mine to reach is the one already falling toward you. He runs trajectory, hardware, and the raise.
BIG WEB is booking capture windows for the 2031 close-approach cohort. Claim a rock before it lands on someone else's manifest. The mission prospectus covers target selection, capture economics, ore handling, and the reservation schedule.
