NASA Seeks Picometer Accuracy For Webb Telescope

NASA Seeks Picometer Accuracy For Webb Telescope Greenbelt MD (SPX) Jul 22, 2016 - Finding and characterizing dozens of Earth-like planets will require a super-stable space telescope whose optical components move or distort no more than a few picometers - a measurement smaller than the size of an atom. It also will require next-generation tools with which to assure that level of stability. With NASA funding, a team of scientists at NASA's Goddard Space Flight Center in G ... more
