Look at how thin our atmosphere is

"Look at how thin our atmosphere is. This is all there is between humankind and deadly space." [1]

June 17 - Alexander Gerst on the #ISS [2]

A thin atmospheric layer enabling life as we know it... [3] [4] [5] [6] [7] [8] [9]

We are just beginning to geo-monitor our thin atmosphere and bio-systems on earth from space...

Beginning with first-ever images of our home planet, Earth, taken from Apollo [10]

We have gone on to eyes-in-the-sky earth-monitoring, our first-gen data and realizations

Of our biosystems, our Overview of 'the only home we've known'...

Isn't it about time we look carefully? [11] [12]

Earth's tropospheric layer, our envelope of breath and life

The "paper thin" layer absorbing human-produced hydrocarbon & emission "externalities"

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