Ten small high-resolution observation satellites for Satellogic — an Argentine company in the midst of deploying a fleet of Earth-imaging spacecraft — successfully launched Friday on a Chinese Long March 6 rocket.

Anton Zeilinger first proposed the idea for a satellite-based quantum communications experiment to the European Space Agency in 2001, but officials did not forward with the idea. A decade-and-a-half later, the world-renowned physicist’s former student leads a Chinese project aimed at proving quantum teleportation and ultra-secure data links at global scale for the first time.

A former space shuttle orbital maneuvering system engine has been delivered to Germany for attachment to the European-built service module destined to steer NASA’s next Orion spacecraft on a course around the moon on an uncrewed test flight in late 2018.
