Topics What is it Like in Near Space? Near Space As The Alternative To Space

Where is Near Space Located? Tallest Building: 2,722 feet tall Highest Mountain: 29,028 feet high Commercial Aircraft: 30,000 – 40,000 feet Lowest possible orbit: 328,000 feet Near Space: above 60,000 feet

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 (ozone)

Relative Humidity Gets very dry Local peaks can indicate cloud layers

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

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

What’s It Like In Near Space? < 5% Sea Level Pressure 0 to –60 degrees F Low Relative Humidity Cosmic Ray Flux 150X Greater Than Sea Level >300 Mile To The Horizon Black Skies, Curved Horizon, and Primary Cosmic Rays - It Looks and Feels Like Space To Me!
