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

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
