NASA collected a sample from asteroid Bennu, but some of it is leaking into space
CNNCNN — The historic collection of a sample from the near-Earth asteroid Bennu by NASA’s OSIRIS-REx spacecraft on Tuesday was almost too successful. They aren’t moving fast, but nonetheless, it’s valuable scientific material.” The spacecraft's sample head is full of rocks and dust collected from the surface of the asteroid Bennu. “The loss of mass is of concern to me, so I’m strongly encouraging the team to stow this precious sample as quickly as possible.” The team will go through another evaluation process this weekend to ensure that the sample head could be stowed in the sample return capsule by Tuesday to protect loose material and keep the precious cargo safe so it can return to Earth. This is not something the team encountered in their test campaign ahead of the mission’s launch – which did include large rocks and the sample collection head being buried by the asteroid’s surface material.
