Reflective Surfaces

The core technology behind China’s artificial moon lies in the reflective surfaces used to direct sunlight. These surfaces, made from lightweight materials such as Mylar, are designed to withstand the harsh conditions of space while maintaining their reflective properties. The reflectors can be adjusted to focus light on specific areas, providing targeted illumination.

Mylar, a polyester film known for its reflective properties, is particularly suitable for this application due to its durability and lightweight nature. The material can be coated with a reflective layer, such as aluminum, to enhance its ability to reflect sunlight efficiently. This technology allows the artificial moon to direct a concentrated beam of light to the desired locations on Earth.

Satellite Control and Positioning

Precise control and positioning of the satellites are crucial for the success of the artificial moon project. Advanced satellite control systems, utilizing thrusters and gyroscopes, enable accurate adjustments to the satellite’s orientation and position. This ensures that the reflected light is directed precisely where it is needed.

The satellites are equipped with a combination of chemical thrusters and electric propulsion systems. Chemical thrusters provide the necessary thrust for major orbital adjustments, while electric propulsion systems offer fine-tuned control for precise positioning. Gyroscopes and reaction wheels help stabilize the satellites and maintain their orientation, ensuring the reflectors are always correctly aligned with the target areas on Earth.
