1. Story
2. The proposition that some products are better made in orbit than on Earth, and the small set of demonstrations that have actually tested it. The physical argument is real: without buoyancy-driven convection and sedimentation, crystals can grow more uniformly, immiscible materials can be alloyed, and fluids behave differently — effects long documented in microgravity research. The economic argument is far narrower, because a product must be worth more per kilogram than the cost of lifting its inputs, operating in orbit and bringing it home. Only a few candidate classes clear that bar: pharmaceutical crystallisation, specialist optical fibre such as ZBLAN, semiconductor substrates, and biological tissue. The concrete milestone came in February 2024, when Varda Space Industries returned a free-flying capsule to the Utah Test and Training Range carrying crystals of the antiviral drug ritonavir grown in orbit — the first commercial manufacturing product returned from space by a private company, and notable as much for the fact that its return was delayed by re-entry licensing as for the chemistry. What has not been shown is that any of it is cheaper than the terrestrial alternative at production volume. Not a place.

23. Evidence
24. 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.
25. Sets out the plan to operate the International Space Station to 2030, to transition low-Earth-orbit human spaceflight to commercially owned destinations, and to conduct a controlled deorbit at end of life. V55 verification basis: nasa.gov was not retrievable in this session; the report's publication year is not stated here because it was not confirmed.
