Designs on Space: the Lifecycle of a Satellite

A Catalyst article about designing, building and testing a spacecraft. There are thousands of man-made satellites orbiting the Earth. Some are only a few hundred kilometres above the Earth and complete one orbit roughly every 90 minutes. Geostationary satellites are located around 40 000 kilometres from the surface of the Earth, completing an orbit of the Earth every 24 hours. Other spacecraft are exploring the solar system. The article looks at how a satellite is made and tested and how it works and is controlled.
