NASA has achieved many firsts in space. But it's never plucked rocks off an asteroid and flown them back to Earth.

That's set to change on Sunday, Sept. 24. After a seven-year mission traveling to asteroid Bennu, collecting material, and then returning home, the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft will drop a capsule into Earth's atmosphere. If all goes as planned, the highly-anticipated metal package will parachute down to the barren Utah desert for a team to retrieve.

The pebbles and dust stored inside are invaluable. Asteroids, like Bennu, are pristine relics from our solar system's formation some 4.5 billion years ago. They'll help scientists better grasp how our planet formed and how life arose. What's more, the sample will provide insight into asteroids that could one day potentially imperil Earth — though there's no known asteroid danger on the horizon.
