The Sun to be the centre of our solar system, just as other stars form the centre of many other solar systems. The Earth and the other planets in our solar system revolve about the Sun. But our sun is on the outskirts of a galaxy called the Milky Way, and the Milky Way is not the only galaxy. The universe is thought to contain something like 100 billion galaxies, and each galaxy might contain something like 100 billion stars.
Engineers design build satellites, and robots that will map and explore those distant planets and stars. We’ll be looking at rockets, robots, probes, and satellites. How does a toilet flush in space? How do you control a robot on another planet? What’s the fastest rocket engine ever built?
The engineers in this zone build flying equiptment that can be used to explore the planets in our solar system, design spacecraft that look at climate change, and build robots to test navigation and sensors for robots being used to explore Mars and the Moon. There’s also an engineer building computers to help spacecraft navigate, and one designing parts for satelites.
