CHNSA Project Presentation Presentation Transcript

  • 1. CHNSAHigh Altitude Balloon Project Castle Hill Near Space Agency
  • 2. Our ProjectProject Goal To fly Mark into space !!!!
  • 3. No … not really  Whew !!!!!
  • 4. High Altitude Balloon ProjectProject Goals• To fly a weather balloon with science instruments and HD camera onboard to 100,000ft (33km) above the earth• Record & log temperature v’s altitude data• Capture the Blackness of space and the curvature of the earth• Track the payload at all times & return it safely to earth• Be able to find it once it lands• Develop a reliable high altitude “near-space” platform for future space missions
  • 5. Why are we doing this project ?• It’s a lot of fun !!• Educational Value – amateur radio, ballooning, electronics, programming, space science, engineering• To enhance our science and engineering knowledge• To challenge ourselves• Our latest Science Project – 5th project, our most challenging and complicated yet !
  • 6. Previous Science Projects• Magnetic Levitating Train• Water powered Rocket• RC Water Rocket Car – World records !!• Build Radio Receiver – Electronics
  • 7. What is Near Space ?• Near Space is “nearly into space”• The region of Earths atmosphere that lies between 65,000 and 350,000 feet (20 to 100 km) above sea level.• Its above where airliners and military planes fly but below orbiting satellites• Very low air pressure 1% of that at sea level• Very low temperature -60 degrees C• Very similar conditions to space
  • 8. Where will we fly
  • 9. Where to Start !!
  • 10. How do we get up there ?• We need a weather balloon and Helium (He) !• 1.8m diameter on the ground – (vol – 3 m^3)• 10m diameter at 100,000ft (30km) (vol 523 m^3)
  • 11. How about getting back ?• Gravity does that for us – but we need to slow down before we crash• We use a 1m diameter parachute to slow down to (18km/hr) to land softly
  • 12. What are we carrying to “near-space”• Our Payloads !!• Science Instruments, Tracking Devices, HD Camera
  • 13. Our onboard Science Package• Arduino programmable computer – Temperature sensor module -> -55C to +125C – Write temp data to onboard SD Card – Piezo buzzer 85dB to help find it on the ground
  • 14. How do we find it again ?
  • 15. Whats Next ?• Fly our first mission - This Summer 2012/13• More Near-Space science missions !• Primary School PicoSats Program – Ping-Pong Satellites – Ideas - marshmellow, gummybears, seeds, bubblewrap, wet sponge, film, any more ideas ? – Each PicoSat is signed and decorated by the student – Each student gets a certificate when returned from near- space
  • 16. Questions ? PicoSat Ideas ?
