What is the difference between a satellite and a space station?

The primary difference between a satellite and a space station lies in their functions and designs. Both satellites and space stations orbit Earth, but they serve different purposes and have distinct features.

Satellites are objects that revolve around planets or other celestial bodies in space. They can be either natural (like the Moon) or artificial (man-made). Artificial satellites are designed for various purposes, such as communication, weather monitoring, navigation, Earth observation, and scientific research. They vary in size, shape, and complexity depending on their intended use. Most satellites are unmanned and are controlled remotely from the ground.

Space stations, on the other hand, are large, habitable artificial structures designed to support human life for extended periods. They provide a stable environment for astronauts to live and work in microgravity conditions, conduct scientific research, and perform maintenance tasks on the station. Space stations, such as the International Space Station (ISS), consist of multiple interconnected modules with living quarters, laboratories, and storage facilities. They also have life support systems, such as air and water recycling, temperature control, and waste management, to sustain the crew on board.

In summary, satellites are primarily unmanned objects with specific functions like communication, weather monitoring, or navigation, while space stations are large, habitable structures designed to support human life and scientific research in space.
