Working under close supervision from ground controllers more than 200 million miles away, the robotic arm on NASA’s OSIRIS-REx spacecraft has begun placing specimens collected from an asteroid last week into a return capsule to bring the material back to Earth in 2023, officials said Wednesday.

A United Launch Alliance Atlas 5 rocket took off from Cape Canaveral on Aug. 8 with the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite, the second launch from Florida’s Coast in a span of less than 35 hours.

The man in charge of the Orion crew capsule program at Lockheed Martin is a lifelong veteran of the space program, beginning his tenure at NASA’s Johnson Space Center in the late 1970s before taking posts in Washington and joining Lockheed Martin to lead the company’s work on the nation’s new spacecraft for journeys beyond Earth orbit.
