Goodbye, Asteroid Bennu, It’s Been Real
Yesterday, NASA’s OSIRIS-REx spacecraft passed by the asteroid Bennu for the last time, ending its two-and-a-half-year relationship with the space rock. But OSIRIS-REx is still lingering in the asteroid’s vicinity, as if hesitant to embark on its roughly 320-million-kilometre return to Earth. That trip will begin in early May.
