Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle spacecraft by type, mission, status and tracking, explain how they work, and cover space law and history with sourced data.

A vehicle designed to fly in outer space, whether crewed or uncrewed, including satellites, probes, landers, rovers, crewed capsules and stations, space habitats, re-entry vehicles and autonomous spacecraft; spacecraft are launched by rockets, operated from the ground and registered under international space law.

What it is for: Exploration, communication, observation and human spaceflight.

It can be identify a spacecraft and its mission; explain spacecraft subsystems; track spacecraft using public data; explain registration and debris rules.
