NASA to Collect, Return Asteroid Sample for First Time

A NASA spacecraft circling an ancient asteroid 200 million miles away is about to reach out and make contact.

The OSIRIS-REx spacecraft will attempt to descend to the boulder-packed surface of asteroid Bennu on Tuesday and snatch a handful of rubble.

It will be America's first crack at collecting asteroid samples for return to Earth, a feat accomplished so far only by Japan.

Scientists want to bring back at least 2 ounces worth of Bennu — about a handful's worth.

The van-sized spacecraft is aiming for the relatively flat middle of a tennis court-sized crater named Nightingale.

Boulders as big as buildings loom over the targeted touchdown zone.

The samples won't arrive on Earth until 2023.
