Q&A with Anton Zeilinger, acclaimed quantum physicist

The third in a new series of Chinese high-resolution mapping satellites lifted off Saturday aboard a Long March 2D rocket, joining two other craft launched into similar orbits in December.

The first flight of the new Chinese Kuaizhou 11 solid-fueled rocket failed to place two small satellites into orbit Friday, and Chinese state media said the cause of the malfunction is under investigation.

China launched a Beidou navigation satellite Friday using a Long March 3C rocket, adding another node to a growing space-based network that Chinese officials say will broadcast positioning and timing signals around the world next year.
