  1. Amateur Near Space Exploration The Do-It-Yourself Space Program

  2. Topics • Cost And Access To Space • Near Space As An Alternative To Space

  3. Cost And Access To Space • Want To Send A Satellite Into Orbit? • Building Costs • Testing? • Construction Time • Launch Costs • Telemetry Stations? • It’s More Of A Barrier Than An Opportunity

  4. Near Space As An Alternative To Space • Look And Feel Of Near Space • It’s Affordable • It’s Quick • Accessing Near Space • Functioning In Near Space • True Stories From The Near Space Files

  5. What’s It Like In Near Space? • < 5% Sea Level Pressure • 0 to –40 degrees F • >300 Mile To The Horizon • Cosmic Ray Flux 150X Greater Than Sea Level • Black Skies, Curved Horizon, and Primary Cosmic Rays - It Feels Like Space To Me!

  6. Atmospheric Pressure • Three Rules Of Thumb • Changes By A Factor Of 3% Per 1000 Feet • Changes By A Factor Of 50% Per 18,000 feet • Changes By A Factor Of 90% Per 50,000 feet

  7. Air Temperature • Drops As You Climb Through The Troposphere • Rises As You Climb Through The Stratosphere

  8. The Near Space Horizon • See The Entire State • Spy On Neighboring States!

  9. Cosmic Rays • Primary Cosmic Rays Are Atoms From Stars • Secondaries Created When Primaries Collide with Air Molecules • Secondaries Further Reduced By The Atmosphere

  10. Near Space Is Affordable • $500 For A Basic Near Space Capsule • $100 For Ground Support Equipment • Local Amateur Radio Support (free!) • $160 Per Launch (to 85,000 feet) • Except For Balloon And Helium, It’s All Reusable

  11. Near Space Is Quick • Build A Capsule Within A Few Months • Build Ground Support Equipment Within A Few Weeks • Design Your Experiments Within ? • Complete A Mission In Time For Lunch

  12. Accessing Near Space • Helium Filled Weather Balloons • Recovery Parachutes • Ascent Rates Of 300 To 1200 FPM • Helium And The Parachute Keeps The Program Safe

  13. Functioning In Near Space • Inexpensive GPS Receiver • Radio Modem • Inexpensive HT • APRS • Basic Stamp Based Flight Computer (CC/PS) • Hobby Servos • MAX186 12 Bit ADC • “AA” Batteries

  14. Near Space Experiments • Determine Cosmic Ray Flux (RM-60) • Atmospheric Temperature Profile • Wind Profile • Remote Sensing The Earth • Technology Tests • Life Sciences • Meteoric Dust • Astronomy

  15. Conclusion • Is Near Space Right For You? • Can You Afford The Initial Cost? • Can You Sustain The Program? • Get Your Technician’s License!
