Osiris-Rex is fast approaching Bennu and will arrive in orbit around the 1,650-foot-wide (500 meters) space rock on December 3, 2018. The spacecraft Completed Inflight Testing of the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) on Nov. 14, 2018. It is scheduled to arrive at Bennu and begin surveying the asteroid up close. The Osiris-Rex spacecraft will initiate an intricate dance with Bennu, mapping and studying it in preparation for sample collection in July 2020. Osiris-Rex will deliver the sample to Earth in Septenber 2023. Scientists suggest that a massive collision between an asteroid and a planetsimal about one billion years ago, may have resulted in the birth of Bennu. The asteroid is quite dark. Like an asphalt road on a hot day, it absorbs most of the sunlight that hits it and later radiates this energy away as heat. This radiation gives Bennu a tiny push, called the Yarkovsky effect, which gradually changes its orbit over time. Osiris-Rex will help unveil the mysteries of our solar system's formation. https://www.asteroidmission.org/statu...
