Releases, data and engineering: where the numbers come from and how the map is made, in the open.

Nearly half the world’s schools are not online. Space Radar is built so that one of them can keep its own copy on an old laptop and teach the sky from it. How that works, what a lesson looks like, and what it honestly cannot do without a network.
A map with a legend tells you everything at once. A guide tells you one thing, then the next. On the 26 narrated trips in Space Radar, how they are written, and three of them retold.
Space Radar draws everything in orbit where it really is, for people who have never heard of an orbital element. Why I think a map of space has to be honest and kind at once, what that costs, and why it is free and open.
A map of space is a pile of other people’s measurements. Who made them, how old they are, which parts are computed, which are photographs and which are honest drawings, and how to send a correction when one of them is wrong.
