Chapter 40: Interstellar Relay Station
To promote transportation between Earth and Mars, thousands of unmanned relay stations will be established between Earth and Mars, serving as stopping points for long-distance spacecraft, providing supplies and transit relay services. Considering the scale and cost of the mission, future relay stations may require cooperation between international and private enterprises, sharing resources and technology to create a platform for global cooperation.
1. Relay Station Location Selection
Orbital position: These relay stations will be located in orbits between Earth and Mars, primarily at Lagrange points—specifically L1 and L2 points, which are located at gravitational equilibrium positions between Earth and Mars, making them suitable for establishing relay stations for long-distance travel. Orbital navigation paths: The relay stations should be positioned along the most commonly used navigation paths, typically the Hohmann transfer orbit between Earth and Mars. The Hohmann orbit is the most energy-saving path, and the relay stations can provide necessary supplies and support for spacecraft. Part three: Development
2. Functions of the Relay Station
Energy and food supplies: During long-distance flights, spacecraft require resources such as fuel, electrical energy, and food. The relay station can serve as a midway "refueling station," providing necessary energy, food, and other supplies. This fuel, such as electrical energy, can be stored in batteries continuously charged by solar panels, or in liquid oxygen, hydrogen, water, and other food transported and stored in containers regularly. Equipment maintenance: Since equipment damage may occur during flight, the relay station can provide simple repair and inspection services to ensure spacecraft remain operational before reaching their destination. Rest and health management: Astronauts on long-term space missions may experience psychological and physiological issues. The relay station can provide astronauts with rest, exercise facilities, and medical services to reduce stress in the space environment. Communication relay: Due to the long distance between Earth and Mars, communication signals may be lost. The relay station can serve as a relay station to help transmit information and reduce signal loss during transmission.
3. Design Requirements for the Relay Station
Sustainability: For long-term operation, the design of the relay station needs to be highly autonomous and sustainable, including the use of renewable energy such as solar power and unattended technologies. Life support systems: The relay station needs appropriate environmental control systems, including oxygen generation, carbon dioxide removal, temperature regulation, etc., to ensure the provision of relay accommodation and leisure services. Radiation protection: Due to radiation hazards in space, the relay station needs to provide effective radiation shielding measures to protect personnel from cosmic radiation and solar wind effects. Emergency shelter facilities: In case of accidents such as fires or gas leaks, personnel should be able to quickly enter shelter compartments to protect their lives.
