  1. Space Balloon – 999 Project Michio InoueSpace Online School 02/05/2011

  2. Galaxy Express 999 Leiji Matsumoto

  3. Earth Orbiting Satellites • Geo-stationary orbit: 36,000km (22,000mi) • ISS: 350-400km (220-250mi) • GPS: 20,200km (12,550mi)  very expensive!

  4. Gateway to Space • SpaceShipOne: 100km • Official “edge of space” • First commercial vehicleto go to “space” • $200,000/person • Balloon: 32km (20mi) • What our focus today • Reachable with <$1000 • Airplanes: 10km (6mi)

  5. Space Balloons • Becoming popular after 2006 • Done by students and hobbyists • CU Spaceflight (Cambridge University) • SABLE (Canada) • MIT undergrads • Students in Spain • etc. etc.

  6. 76,900 ft 105min 22,900 ft • Canadian group (SABLE) • August 2007 4,700 ft 30min. 117,597 ft (max) 140min. 6min. Launch t=0min. 69,700 ft. 148min. Retrieve 7,600 ft 180min. 45,400 ft. 157min. Descent with parachute 1,100 ft. 185min 0 ft 186min Photo: Nikon Coolpix P2 http://www.sbszoo.com/bear/sable/sable3.htm

  7. Balloon on the Ground • KCI 1200 – popular weather balloon • Flaccid Body Length: 226 cm (7.4ft) • Average Weight: 1200 g (2.4lb) http://www.sbszoo.com/bear/sable/sable3.htm

  8. Balloon before Releasing • Gross Lift: 3440 g • Payload: 1050 g • Diameter: 179 cm • Rate of Ascent:320 m/min (12mph) Balloon Parachute Payload

  9. System • Example: by UK High Altitude Society

  10. Images/Videos • Cameras programmed to take picturesat a fixed interval • Video always on • No live broadcast

  11. Even Teddy Bears Went to Space! http://www.dailymail.co.uk/sciencetech/article-1091896/Out-world-British-teddy-bears-strapped-helium-weather-balloon-reach-edge-space.html

  12. What’s it like at 32km?

  13. How Does It Come Down? • It “pops” at the bursting altitude: 33.2 km • How big is the balloon? • Ideal gas law: • At the ground level • D0 = 1.76 m • p0 = 101325 Pa • T0 = 15 C (= 288 K) • At 32km • p1 = 868 Pa • T1 = -44 C (= 229 K) • Diameter at Burst: 8.6 m! (28 ft) or  

  14. Descent http://nearspaceventures.com/w3Baltrak/readyget.pl • Maximum speed:150 mph • Parachute slows it down • Balloon predictor • Time • Launch site • Ascent rate • Descent rate  predicted GPS track • Just an indicator

  15. Retrieval • The balloon travels about 20 miles horizontally • A transmitter in the payload box transmits its GPS location

  16. Retrieved Data • GPS track, temperature, pictures, movies, etc.

  17. Mission Ideas • Aim to launch balloons every 6 months • 2.3 lbs payload, iPhone as a primary computer • Science • “Would the cockroach survive at 30km?” • “Boiled egg vs raw egg” • Potato chips • Ping-pong ball • Wind, Temperature, GPS position • Gliding from space (2011) • Live images/videos (2012) • Staying aloft (2013)

  18. Questions?

  20. データをとって送信するiPhone用のプログラムの開発 ← 一番時間がかかるデータをとって送信するiPhone用のプログラムの開発 ← 一番時間がかかる • パラシュートの折りたたみ&展開実験(ビルの屋上から) • 着地の際の衝撃の評価  • 第2回公開実験:2011年秋 • 小型HDカメラの撮影映像を送信する • パラシュートに代わる飛行体による滑空帰還  • 第3回公開実験:2012年春 • ライブ映像送信と滑空帰還(その2) • 高高度(地上20キロ辺り)の滞空実験
