CAPE CANAVERAL, Fla. (AP) — An asteroid that may hold the key to life is getting its first visitor in billions of years.
Asteroid Bennu, a black roundish rock taller than the Empire State Building, is the intended target of a NASA spacecraft set to blast off Thursday night. Not only will the robotic probe named Osiris-Rex fly to this ancient asteroid, it will scout it out for two years before scooping up some gravel and dust, and deliver the samples back to Earth.

Bennu (BEHN'-oo) was discovered in 1999 and got its name for this mission 14 years later. A North Carolina schoolboy had the winning entry in an international student naming contest held by the University of Arizona, the Planetary Society and others; he likened the boxy spacecraft, with its twin solar wings and 10-foot mechanical arm, to the heron of Egyptian mythology, Bennu. The spacecraft shares that Egyptian motif, bearing the mythological god's name Osiris. Osiris-Rex also doubles as a NASA acronym.
