Q&A with Anton Zeilinger, acclaimed quantum physicist

For the second time in less than a week, China has debuted a new type of rocket designed to broaden the scope of the country’s Long March launcher family. This time a solid-fueled booster named the Long March 11 blasted out of a mobile launch canister with four Chinese tech demo satellites.

Completing an eight-day test flight around the moon to verify technologies for a planned lunar sample return mission, an unpiloted Chinese space capsule re-entered Earth’s atmosphere at blazing speed and parachuted to a successful landing.

Chinese officials say they plan to share a portion of the nearly 4 pounds of lunar material returned by the Chang’e 5 mission with other countries, but an allocation for U.S. scientists will hinge on a change in U.S. policy restricting cooperation between NASA and China’s space program.
