Orbital spacecraft are like the busy toolshed of space—machines we send up there to get stuff done while circling planets, moons, or just hanging out in orbit. They come in three main types: satellites, orbiters, and space stations, each serving a different purpose but sharing one key feature—they stay in space, zooming around in carefully balanced orbits. Let’s explore the realm above Earth’s atmosphere with satellites and space stations, facilitating communication, observation, and scientific research.

Satellites are the ultimate multitaskers, used for everything from tracking weather patterns and enabling GPS navigation to helping you stream your favorite show. They orbit Earth (or sometimes other planets) at different heights, depending on their jobs—some closer for detailed observation and others much farther out to cover huge areas.
Orbiters are more adventurous. Instead of sticking close to Earth, they’re sent to other planets, moons, or celestial bodies to study them up close but from a safe, looping distance. For example, a Mars orbiter maps the surface, looks for water, or even acts as a communication link for rovers on the ground.

Space stations are like floating science labs where astronauts live and work. The most famous one, the International Space Station (ISS), orbits Earth at over 17,000 miles per hour. It’s a massive collaboration between countries, packed with experiments, tools, and people doing everything from growing plants in microgravity to testing how humans adapt to long stays in space. Space stations are essentially humanity’s home away from home, a stepping stone for future deep-space missions.
