A cable-climbing capsule ascends from an Earth ground station into the black of orbit, illustrating the real proposed "space elevator" concept: a fixed cable anchored to the ground and tensioned by a counterweight/orbital mechanics, with climber vehicles mechanically gripping and ascending it instead of using rockets. The scene layers a shader-based sky dome, a Fresnel rim-glow atmosphere shell, a 6000-point starfield, and a pooled set of climbing capsules each dragging an additive-blended particle trail.
