Rockets use powerful engines to escape Earth's gravity. Most rockets are launched from special launch pads. Rockets carry satellites, astronauts and supplies into space., Astronauts must train for many years before travelling into space. They practise working in low gravity using special equipment. Astronauts learn how to fix problems quickly during missions., Mars is known as the Red Planet because of its dusty surface. Scientists believe Mars once had water on its surface. Rovers are used to explore Mars and send information back to Earth., Spacecraft must survive extreme heat and cold. Strong materials protect astronauts and equipment. Technology is carefully tested before space missions begin.
