An orbital greenhouse with citrus trees circles above a cracked ice moon.

Ice moon greenhouse in orbit

Prompt and Settings

A sealed orbital greenhouse, rotates above an ice moon while botanists tend citrus trees inside clear pressure domes. The station includes truss rings, water tanks, root beds, and frost-coated service pods against a field of stars and blue-white surface cracks below. A square camera frames the habitat from outside at a slight tilt. Reflected moonlight and plant lamps create mixed color. Sci-fi environment art, precise hard-surface design, luminous glass, believable scale, and clean atmospheric haze.

Why This Prompt Works

The greenhouse offers a science-fiction subject centered on life support and orbital engineering rather than a generic spacecraft. The outside tilted camera phrase defines the composition, showing the domes, trusses, and icy moon together. Chroma1-Flash can use the contrast between reflected moonlight and plant lamps to separate the cold exterior from the warm interior, with hard-surface detail supporting believable scale.
