NASA's Mega Green Screens for Space Flight?

NASA is the world's largest consumer of HELIUM
Helium is used to launch "Satellites" which are Balloons!

A Balloon does NOT go into "Space"
It floats around up in the atmosphere all day
Occasionally they'll crash land like the Samsung Selfie satellite

Research Balloon Satellite Launches!
And research Michoud Assembly and their 2 massive "Stages" for filming Hollywood masterpieces right in New Orleans!

Biggesr consumer of Helium AND it looks like Green Screen materials as well
