In a first, NASA returns asteroid samples to Earth
The collected rocks and soil could help scientists unlock secrets about the solar system and how life emerged on this planet.
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.
