Now, it’s the turn for the earth to save itself from the scorches of the sun! It will soon get an umbrella to reduce its temperature — by building a massive space sunshade! But, how?!
A University of Arizona professor, Roger Angel, thinks this as a solution by building 20,000 billions of very small spacecraft! Each of these spacecrafts weighs about a gram and will be orbiting a million miles above our heads. And the ‘sun-umbrella’ will cost $2,500 billion!
Once muted and kicks off, this plan — costing $100 billion per year — would be deployed over a period of 25 years!
Hey! Am not cracking a jock! To further his research on this idea, Roger has received a grant from the NASA Institute for Advanced Concepts in July 2006. He works at the Department of Astronomy of the University of Arizona as Director of the Steward Observatory Mirror Laboratory and the Center for Astronomical Adaptive Optics.
