NASA's Osiris-REX mission has successfully touched down on the asteroid Bennu to collect a sample of its surface for return to Earth.
NASA's Osiris-REX mission has found evidence of ancient water flows on the surface of asteroid Bennu.
NASA has picked the "Nightingale" site, located within a small crater on the asteroid Bennu, for its Osiris-REX mission to sample next year.
The Osiris-REX spacecraft will sample one of four sites on the asteroid Bennu in July 2020.
The NASA spacecraft detected signs of hydrated minerals on Bennu's surface, suggesting that the asteroid's larger parent body once hosted liquid water.
