Every route runs backwards from a date.
Give a child’s age and a destination. The map shows the rungs between the two — what is still ahead, what has already gone, and where the preparation exists.
This map is a suggestion, not a schedule. It shows one sensible way to build practice and proficiency toward a destination — every child prepares differently, and reaching a rung is never a guarantee of a place.

The next thing is the Physics Year. It runs for one academic year from August and prepares the transition the route ahead assumes — four of the destinations on this map begin with it.
1 of 11 rungs are already behind. Of those, 1 sat on the main line — Astro Pi Mission Zero. What remains is a compressed route, and it is shown in full below.
Of the 9 rungs still ahead, Troupe prepares 1.
