To explore the camouflage property of photonic crystals in a practical application, we design a broad-new Ge/ZnS one-dimensional photonic crystals for spacecraft outside the atmosphere. This designed structure achieves a high average reflectivity of 90.5% at $3\sim 14\ \mu \mathrm{m}$ in our simulations. What's more, the total infrared radiance of photonic crystals decreases dramatically at high temperature, which proves the infrared camouflage characteristics of the designed structure.
