In a first, NASA returns asteroid samples to Earth

A capsule containing precious samples from an asteroid landed safely on Earth on Sunday, the culmination of a roughly 4-billion-mile journey over the past seven years.

A capsule containing precious samples from an asteroid landed safely on Earth on Sunday, the culmination of a roughly 4-billion-mile journey over the past seven years.

The asteroid samples were collected by NASA’s OSIRIS-REx spacecraft, which flew by Earth early Sunday morning and jettisoned the capsule over a designated landing zone in the Utah desert. The unofficial touchdown time was 8:52 a.m. MT, 3 minutes ahead of the predicted landing time.

The dramatic event — which the NASA livestream narrator described as “opening a time capsule to our ancient solar system” — marked a major milestone for the United States: The collected rocks and soil were NASA’s first samples brought back to Earth from an asteroid. Experts have said the bounty could help scientists unlock secrets about the solar system and how it came to be, including how life emerged on this planet.

What scientists could learn from asteroid sample collected by NASASept. 24, 202301:58Bruce Betts, chief scientist at The Planetary Society, a nonprofit organization that conducts research, advocacy and outreach to promote space exploration, congratulated the NASA team on what he called an “impressive and very complicated mission,” adding that the asteroid samples are the start of a thrilling new chapter in space history.

“It’s exciting because this mission launched in 2016 and so there’s a feeling of, ‘Wow, this day has finally come,’” he said. “But scientifically, it’s exciting because this is an amazing opportunity to study a very complex story that goes way back to the dawn of the solar system.”
