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.

The sampling mechanism on NASA’s OSIRIS-REx spacecraft is stuffed with specimens captured from asteroid Bennu earlier this week — so full that some of the rocks are floating out into space. Officials said Friday they will stow the samples inside the mission’s Earth return capsule sooner than planned to minimize the loss of asteroid material.

The first images beamed back to Earth by NASA’s OSIRIS-REx spacecraft after it briefly landed an asteroid buoyed expectations Wednesday that the probe collected enough samples to meet the mission’s minimum requirement for return to Earth.

A robotic arm extended from NASA’s OSIRIS-REx spacecraft briefly contacted the rugged surface of asteroid Bennu Tuesday to gobble up pristine samples, a climactic moment in the $1 billion mission to bring asteroid material back to Earth in 2023.

Mars rovers go through seven minutes of terror when they plunge into the Martian atmosphere at hypersonic speed. NASA’s OSIRIS-REx spacecraft will take a more glacial approach to its asteroid target Tuesday, and the event will be more akin to four-and-a-half hours of mild anxiety for ground teams, according to the mission’s operations manager.

Flying on autopilot more than 200 million miles from Earth, NASA’s OSIRIS-REx spacecraft is on track for a daring touch and go landing on an asteroid Tuesday to grab a sample for return to scientists eager to scan the specimens for clues about the history of the solar system.
