The Earth's Atmosphere

Approx 4/5 of the atmosphere mass is in the Troposphere, which varies between 4 and 12 miles in height

The Earth's atmosphere is an extremely thin sheet of air extending from the surface of Earth to the edge of space

The thickness of the atmosphere is about 62 miles (100 km)

Astronaut's who have seen and experienced 'the overview'

"Earthshine" -- The Space Station basking in blue Earthshine as the rising sun pierces our razor-thin atmosphere to cover the Space Station with blue light

§

I’ll never forget this place... seeing this makes the heart soar and the soul sing. - Astronaut Doug Wheelock

§

“I still have trouble comprehending that this impossibly thin blue curve keeps everything alive beneath it.” - Astronaut Reid Wiseman

§

"Look at how thin our atmosphere is. This is all there is between humankind and deadly space." - Astronaut Alexander Gerst

§

""When we look down on the Earth from space, we see this indescribably beautiful planet. It looks like a living, breathing organism. But it also at the same time looks extremely fragile... We're all basically living in this one eco-system called Earth and everything you do on one side of the eco-system affects the other side." - Astronaut Ron Garan
