Reusable orbital launch

1. Story
2. The recovery and reflight of orbital-class launch hardware, achieved operationally for the first time by SpaceX's Falcon 9 first stage. The technique is propulsive: the booster separates, flips, relights a subset of its engines to cancel downrange velocity or to boost back toward the coast, re-enters through its own engine plume, and lands vertically on legs at a coastal pad or on an autonomous drone ship. The first successful landing was on 21 December 2015 at Cape Canaveral; the first reflight of a recovered booster followed on 30 March 2017. What reuse changed is not the physics but the economics of cadence — a recovered booster removes both the cost of a new stage and the production-rate ceiling that limited how often anyone could fly. Payload fairings were subsequently recovered and reflown as well. The limits are equally real: only the first stage and fairing are recovered on Falcon 9, the second stage is expended every flight, and recovery costs performance, so the highest-energy missions still fly expendable. Not a place.

11. Evidence
12. Compiles inflation-adjusted price-per-kilogram figures for orbital launch vehicles across the space age and documents the methodological distinction between advertised price and actual cost. V55 verification basis: the dataset was not retrieved in this session, so this pack quotes no figure from it and states the decline only as an order of magnitude.
13. Supports the fact that commercial orbital launches and commercial reentries from United States territory occur under FAA licence, and that a commercial reentry requires a licensed and approved landing site — the constraint that delayed the first commercial manufacturing return. V55 verification basis: FAA records were not retrieved in this session; no licence number is cited and mission dates are stated from author knowledge.
