September - October 2024

Dante Lauretta sat in the backseat of a helicopter hovering high above a remote patch of Utah desert, waiting for a small, twinkling speck in the sky to plunge toward earth.If you didn't know better, you might think what was beginning to burn through the skies above the American southwest in the early hours of September 24, 2023, was a shooting star. But it wasn't a shooting star. Or a meteor. It was a dishwasher-size capsule filled with bits of ancient asteroid-priceless matter from the dawn of the solar system. In other words, it was a treasure chest moving at 27,000 miles per hour and sizzling at a temperature half that of the sun's surface.

Chasing an Asteroid - How NASA defied incredible odds to get its asteroid-hunting osiris-rex mission off the ground and in the process upended what we know about our solar system.

Dante Lauretta sat in the backseat of a helicopter hovering high above a remote patch of Utah desert, waiting for a small, twinkling speck in the sky to plunge toward earth.

That small streak of light represented the end of a NASA-led interplanetary mission suffused with peril. Lauretta and his colleagues had spent nearly 20 years building a spacecraft designed to collect material from an asteroid and return to Earth. From these precious grains, they hoped to gain insight about the formation of the solar system, of Earth, and maybe even of life itself.

What the capsule had to do now, completely autonomously, was simple: stay in one piece as it reentered the atmosphere, open its parachutes, and softly touch down on an Air Force bombing range without detonating any unexploded ordnance nearby.
