After two years of surveying the asteroid, the mission team chose a spot it named Nightingale, near the asteroid’s north pole.

Osiris-Rex extended a vacuum tube to grab a material sample from Bennu in 2020, punching into the asteroid’s soft surface without actually landing on the space body, which is a loose amalgam of rocks, dust and debris held together by gravitational force.

Other agencies and labs analyzed the data and made more observations to come up with the asteroid’s path and description.
