A rocket at the centre of the scene
The rocket is the tallest element and the natural meeting point, built upright so its length reads from across the venue. Around it the planets sit at lower heights, each a lit sphere with craters picked out on the surface, so the scene reads as a small solar system rather than a single object. The spacing is wide enough that the rocket and the nearest planet never crowd the walking line, which keeps the orbit route open even when the area is busy.
A path that walks the orbit
The visitor route is a walkable orbit ring that circles the rocket, so people move around the scene instead of standing in front of it. The ring is broken by the planet placements into a gentle sequence of stops, each one a different view of the rocket and the next sphere, which is what gives the scene its sense of travel. It is wide enough for a pram or a wheelchair and lit low, within the dimmable scene total, so the planets stay the bright focus.
Craters that catch the light
The planet surfaces carry lit craters, small dimples that catch a cooler tone than the body of the sphere, which stops the planets reading as plain balls after dark. Each planet is its own zone, so one can be dimmed during service without losing the orbit, and the crater pattern can be retuned without rebuilding the frame. The rocket runs a steadier glow so it holds its role as the anchor while the planets vary around it.
Re-assembling a space set
The scene ships as segment-linked frames, the rocket in the largest crate and the planets as named spheres that bolt to their bases on site. Re-assembly follows the orbit plan so the central rocket goes in first and the ring path is laid around it, which keeps the walking line clear while the structure rises. Between seasons the silk covers are removed and rolled and the steel frames store flat, ready to be re-dressed in the same scheme the following year.
