Q&A with Anton Zeilinger, acclaimed quantum physicist

China launched an innovative satellite Wednesday that will look for X-ray signals from pulsars, the fast-spinning super-dense remnants of collapsed stars, to determine its exact location in space.

Two solid-fueled Kuaizhou 1A rockets fired into orbit from the same spaceport in northern China Saturday, demonstrating a further advance in China’s aim for a quick-response, on-call satellite launch capability.

A Chinese marine observation satellite designed to monitor ocean pollution, measure sea temperatures and track ship movements successfully launched Friday on top of a Long March 2C rocket.
