NASA decided in December taht Osiris-Rex would collect samples at the Nightingale area of the asteroid, despite the location having "some hazards around it," according to principal investigator Dante Lauretta.

Sample collection is scheduled for mid-2020, with Osiris-Rex to return to Earth in late 2023.
