NASA-led program tracks near-Earth objects and refines paths as new observations arrive, with routine revisions to distances and risk assessments. Recent reporting notes trajectory refinements for near-Earth asteroids and continuous monitoring by space-based networks to refine close-approach predictions over weeks to months. The planetary defense program provides public updates on new observations and trajectory revisions, emphasizing that changes reflect improved measurements rather than imminent danger. Asteroid monitoring continues to inform assessments as data accumulate, helping scientists improve predictions over time.

NASA is celebrating the successful end of a seven-year, $1 billion mission to collect and return a sample from an asteroid named Bennu. Mark Strassmann reports scientists hope the sample will provide clues about the origin of the solar system. A capsule carrying rock and dust samples collected from the asteroid Bennu is scheduled to land in the Utah desert Sunday morning. The samples are being deposited by NASA's OSIRIS-REx spacecraft, which after releasing the capsule will depart for a trip...
