WASHINGTON, Nov. 13 (UPI) -- U.S. scientists say they've created a sunshield for the James Webb Space Telescope that can withstand severe cold and heat, radiation and meteorite impacts.
National Aeronautics and Space Administration scientists, along with Northrop-Grumman Corp. engineers, said the space telescope needs such a sunshield to block heat from the sun so its cameras and instruments can operate properly 1 million miles from the Earth when it launches in 2013.
