Spacecraft technology refers to the design and construction of vehicles that travel beyond Earth's atmosphere. These vehicles, known as spacecraft, are equipped with various systems for navigation, communication, and life support. They can be used for a range of purposes, including scientific research, satellite deployment, and crewed missions to destinations like the International Space Station. Key components of spacecraft technology include propulsion systems, which help maneuver the vehicle in space, and power systems, often relying on solar panels or nuclear energy. Advanced materials and engineering techniques are also crucial for ensuring that spacecraft can withstand the harsh conditions of space, such as extreme temperatures and radiation.
