English: OSIRIS-Rex mission to asteroid Bennu: The acronym OSIRIS is in reference to the ancient Egyptian mythological god Osiris, the underworld lord of the dead. He was classically depicted as a green-skinned man with a pharaoh's beard, partially mummy-wrapped at the legs and wearing a distinctive crown with two large ostrich feathers at either side. His name was chosen for this mission as asteroid Bennu is a threatening Earth impactor capable of causing vast destruction and death. Rex means "king" in Latin.
