Key Info
  • How satellites are created to survive extreme environments
  • Duration: 05:47
  • Satellites in space have to endure very hostile extreme space environments. Temperatures fluctuate between -200 to 150 degrees centigrade. It is imperative the interior on board electronics temperature is fairly constant so the satellite functions. We find out how engineers tackled this problem and solved it. We are introduced to a modern material called Kapton and clever engineering using panels and pipes that form part of the satellite structure, acting as radiators. Graphics and filming inside the factory are used to explain the production process. Created especially for Class Clips from the BBC series How To Build, first broadcast in November 2011.
  • Subject:

    Design and Technology

       Topic:

    New Technologies

  • Keywords: Kapton, insulating materials,satellite, modern material, electronics, howtobuild, women in engineering, develops
Ideas for use in class
  • Introduce the concept of thermal design engineering. Provide a case study for the modern material Kapton. Discuss what Kapton is made from and what the characteristics and properties are. Speculate where else it might be used. Discuss why special materials might be suitable to solve certain problems. How do the satellite's heat pipes act as radiators? Also see clip 12960.
