=> [mailto:[EMAIL PROTECTED] On Behalf Of Graham Dobson => => of all the schemes proposed, the most ambitious (and => expensive) idea would be to place a giant sunshade in space => at the inner Lagrange point, the position on the line => between the Earth and the sun where the combination of => centripetal and gravitational forces allows an object to => maintain a constant position between the two. If the object => is big enough, it could block out enough of the sun's rays => to cool the Earth. Roger Angel, an astronomer at the => University of Arizona, has suggested assembling a cloud of => millions of small reflecting spacecraft less than a metre => across at this point , where together they would block out => 1.8% of the sun's rays. => => This is a costly "last option" but Dr Angel has received a => grant from NASA to explore the idea. =>
What a waste! The Lagrange point in question is unstable and requires regular external adjustments to maintain position. The funding of such a project, even the funding of the investigation of such a project is a boondoggle and demonstrates a significant disinterest in the welfare of our troops in Iraq.
