A NASA spacecraft has really made a mess of things on the asteroid Bennu, and scientists are thrilled.

It will take time to confirm if OSIRIS-REx did, in fact, collect pieces of Bennu, but so far everything appears to have gone as planned.

“We really did kind of make a mess on the surface of this asteroid. But it’s a good mess,” OSIRIS-REx principal investigator Dante Lauretta, of the University of Arizona, told reporters from the mission’s Lockheed Martin control center in Littleton, Colorado. “It’s the kind of mess we were hoping for.”

OSIRIS-REx touched a rocky region of Bennu called Nightingale with a spindly arm tipped with a hubcap-shaped collection plate. At the moment of contact, which lasted just 6 seconds, the spacecraft fired off a puff of nitrogen gas to essentially blow tiny pieces of the 1,640-foot-wide (500 meters) Bennu into its collection device.
