Episode Description from the Publisher

In September 2023, a small NASA capsule streaked through Earth’s atmosphere and landed in the Utah desert, carrying 122 grams of material from the asteroid Bennu. That material has existed for more than four and a half billion years, preserving clues from the earliest moments of the solar system. At Lawrence Livermore National Laboratory, a team of scientists is now studying tiny fragments of the sample with extraordinary precision, examining isotopes and microscopic minerals to read the stories locked inside. As studies continue, they are revealing how some of the ingredients used by life on Earth are also present in ancient space rocks.
