NASA Says Samples Collected From Asteroid Are Leaking Into Space

NASA reported that a flap on the Osiris REx spacecraft is unable to close securely, causing collected particles to leak into space. The blockage is due to large particles collected from an asteroid. The mission team is working to stow as much of the samples as possible to ensure enough material is returned to Earth in 2023 for research. Approximately 400 grams of particles were collected, and the spacecraft remains in good condition.
