Reusable Booster Stage
AssemblyFirst stage that burns for ~160 s, separates near 2 km/s, then flies itself back through entry and landing burns to touch down on four legs, carrying roughly ten tonnes of hardware that exists only for recovery. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
