2. Let’s Design the first Cambodian Spaceship!!!

3. Why? Our planet is a small and life on it is fragile By seeing the earth from outside, some people begin to appreciate things differently Especially children (and it’s fun!)

4. From Space… There is no ‘them’, just ‘us’ You can see the place where every human that ever was alive spent his life You can appreciate the totality of our natural resources We can see the importance of thinking of the planet as a closed system

5. Closed System = Finite resources Nowhere else to throw trash Nowhere else to farm land Nowhere else to go conquer Nowhere else to get resources from No undo Just us Much of our society’s governance methods, planning capacities and maybe even our religions evolved in ‘open system’ mentality We’ve reached the limit of that illusion

6. Perspective The atmosphere of earth is thinner than the layer of paint on a football All life on earth is in that thin layer

7. The atmosphere and our target 80 km 30 km

8. Don’t you need a rocket to go to space? - Nah, with something like SpaceShipOne you are OK to touch space and fall back So why do space programs use rockets? - To develop enough speed for orbit, (to stay in space and not fall back down) you need a LOT of energy (many Kg of fuel per Kg of cargo!) – little planes are not enough So…technically we won’t be reaching “Space” but it’s close enough for our goal!

9. Let’s Design the first Cambodian Spaceship!!! Let’s get with the program

10. Analyzing a complex project Risks Architecture Process Helium Balloon lifting a box with cameras and GPS Trackers Build system, test it, launch, go recover it Anticipate problems and work around them

12. Helium

13. Ropes

15. Paint

16. Signs

17. Parachute

18. $ for reward

20. Radar ReflectorEvery Critical Subsystem must have two primary independent units

21. Schematics

22. Helium balloon – not Hydrogen! Parachute Small radar reflector Laminated recovery note Payload Antenna People

26. Lat/Long/Alt

27. Reliable range (6W transmission)

28. Many parts (risky electronics)

29. GPS Works above 30km (Lassen iQ)

31. Unreliable (<50%)

32. No altitude reports

33. Doesn’t work above 7000mts

34. Doesn’t need GSM signal

35. Rugged, low batt usage

36. 24 hs of tracking from launch

38. Chase & Find!

39. Important Parts - Optics 2nd hand Canon camera CHDK on 2nd partition of SD card GOPro video camera Many batteries No case

40. “Ballooning” as a Hobby Some have it as a hobby… Weather scientists Electronics DIY – Do It Yourself Playing with GPSs Maps and imagery Radio electronics, radio control, telemetry “Extreme Geocaching” (your target falls from 30km!) The fun –and tension- of the chase You can develop it in your own direction We do it to take pictures of the earth Green? Risks with batteries & helium shortage biggest concerns. Use LiPolyrechargeables and in the future learn to safely do Hydrogen launches

41. Process Plan Build PreLaunch Launch Recovery Design Materials Team Event Schematics Licenses Risk Analysis Assemble Test Curse Assemble again Test …. Prediction Permits Plan & Schedule Batteries Memory Travel Checklists Inflate Assemble Go/No-Go Takeoff! Chase Maps Vehicles (car boat bike) GPSs GET NERVOUS SEARCH & FIND

44. GPS fails

45. Radio Fails

46. Interference

47. Battery Dead

48. Lost Contact

49. Bad Roads

50. Payload Stolen

51. Camera freezes

52. Laptop Dies

53. Firmware dies

54. Balloon gets damaged, burst

55. Incorrect amount of helium

56. Helium or Hydrogen?

57. Weather gets bad

58. Water Landing

59. Inaccessible terrain

60. Parachute gets tangled

61. SPOT tracker dies

62. No cell signal

63. Lands on someone’s land

64. Batteries freeze

65. Shaky pics

66. Wind models wrong

67. Airplane runs into it

68. etcMany industries use “Risk-Driven-Design” to build great products

69. Unique Cambodia Risks & Mitigations Safety: Must land away from mined/UXO areas Takeo has lowest statistics, << 1% of Cambodia’s accident statistics All search people MUST have LM/UXO briefing Road Conditions Be patient and drive safely SSCA and CATS Regulations Avoid all class B…D airspace Spend little time in class A Build extended radar reflector for TACAS Wide clearing from any national borders Water landing: rice paddy, puddle or lake Design a payload that can land in water Inflatable boat Boots. Change of clothes to get wet? Weather changes faster Good Luck, launch in morning

71. We may loose all the equipment

72. Problems may arise at inflation

74. Need 3 Teams Team 1: Design and Build a large and lightweight Radar Reflector Team 2: Start assembly of payload encasing Team 3: Localize Logistics

75. Radar ReflectorTCAS Onboard Air Collision Avoidance, large mylar, wire and graphite structure Goal: Large (>1m2) radar-reflective 3D element

76. Payload Case Goal: Present and prepare basic Payload structure Easy to assemble and disassemble Cameras are ‘stable’ in their position (no wiggle) Thermal insulation compartment Top ‘layer’ for GPS and SPOT tracker

77. Logistics Goal: Khmer language and culture notes Goal: Establish Launch and Land sites Easy for folks to understand – even cartoons? Clear instructions: Leave outside with view of sky, we will pick it up, reward offered Safe, reachable spot. Discuss alternatives, propose top 2 with pros and cons

78. Need your Help! Logo – what is the logo that we should give it? Plan Launch to hit good land site (in Takeo?) Need Dolly - Bedsheets to use as clean surface

79. What about launch? Still arranging logistics Expect the unexpected Everyone is responsible for themselves and their family/friends Be ready for many hours in the car! edjez@ourpalebluedot.net

80. Thanks!

81. There are people dying of hunger in the world – isn’t space exploration a waste of precious resources? Space exploration is almost nothing compared to defense spending, and minor when compared to profit of major potentially unsustainable industries… and smaller than major relief and aid efforts. IMO ROI is positive.
