OSIRIS-REx then achieved its “Matchpoint” burn, where the spacecraft matches the asteroids rotation so it can fly above the sample site.This put the spacecraft more detailed than it has ever been to the asteroids surface, at 131 feet away. Bennu has a shape similar to that of a spinning top, and its a “rubble pile” asteroid, which is a grouping of rocks held together by gravity rather than a single object.OSIRIS-RExs instruments have validated that hydrated minerals, consisting of magnetite, are prevalent and abundant on the asteroid. Bennu most likely came from in the primary asteroid belt, having actually broken off of a larger asteroid in the belt in between Mars and Jupiter a couple of billion years ago.

The collection will take place on October 20, making it NASAs very first spacecraft to gather a sample from an asteroid and return it to Earth.

Bennu is basically a remaining from the development of our solar system billions of years ago.Early in the mission, the spacecraft observed unexpected plumes of product ejecting from the asteroid into area. Bennu probably came from in the main asteroid belt, having actually broken off of a bigger asteroid in the belt between Mars and Jupiter a couple of billion years back.
