Today at 19:43 UTC, OSIRIS-REx entered orbit at asteroid Bennu. In so doing, it accomplished both the tightest orbit (at an altitude under 2 kilometers) and the orbit of the smallest object ever. UPDATE: Early science results from OSIRIS-REx discussed at New Horizons MU69 flyby event.
After more than 11 years in deep space, after unveiling the two largest uncharted worlds in the inner solar system, after overcoming myriad daunting obstacles, Dawn's interplanetary adventure has come to an end.
Hayabusa2 didn’t quite make it down to its intended 60-meter distance from asteroid Ryugu yesterday. There is nothing wrong with the spacecraft; it’s healthy and returning to its home position. The team will adjust parameters and give it another try in the future.
A fantastic story of adventure, exploration and discovery is reaching its denouement. In the final phase of its long and productive deep-space mission, Dawn is operating flawlessly in orbit around dwarf planet Ceres.
