The Do-It-Yourself Space Program
Amateur Near Space Exploration
Topics
• Cost And Access To Space• Near Space As An Alternative
To Space
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
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
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!
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
Air Temperature
• Drops As You Climb Through The Troposphere
• Rises As You Climb Through The Stratosphere
The Near Space Horizon
• See The Entire State
• Spy On Neighboring States!
Cosmic Rays
• Primary Cosmic Rays Are Atoms From Stars
• Secondaries Created When Primaries Collide with Air Molecules
• Secondaries Further Reduced By The Atmosphere
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
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
Accessing Near Space• Helium Filled Weather
Balloons• Recovery Parachutes• Ascent Rates Of 300
To 1200 FPM
• Helium And The Parachute Keeps The Program Safe
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
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
Conclusion
• Is Near Space Right For You?
• Can You Afford The Initial Cost?
• Can You Sustain The Program?
• Get Your Technician’s License!
