NASA asteroid probe is overflowing with space-rock samples

NASA’s first-ever asteroid-sampling operation apparently went a little too well.

The agency’s OSIRIS-REx probe snagged so much dirt and rock from the surface of the near-Earth asteroid Bennu on Tuesday (Oct. 20) that the spacecraft’s sampling mechanism didn’t close properly, allowing some of the collected material to escape into space, mission team members announced Friday (Oct. 23).
