☄️New shape model of Bennu? ✅? Water in the asteroid’s clay? ✅? Pics showing rugged terrain? ✅Today we announced that data from our OSIRIS-REx (@OSIRIS_REx) mission has revealed water locked inside the clays that make up asteroid Bennu. The presence of hydrated minerals across the asteroid confirms that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the spacecraft to study. When samples of this material are returned by the mission to Earth in 2023, scientists will receive a treasure trove of new information about the history and evolution of our solar system. Additionally, data obtained from the spacecraft’s cameras corroborate ground-based telescopic observations of Bennu and confirm the original model released in 2013. That model closely predicted the asteroid’s actual shape, with Bennu’s diameter, rotation rate, inclination, and overall shape presented almost exactly as projected. The newest shape model can be seen here. One outlier from the predicted shape model is the size of a large boulder near Bennu’s south pole. It’s much larger than we thought!
