Far above Utah on Sunday morning, NASA's OSIRIS-REx probe is scheduled to drop a capsule into the desert containing about 250 grams of sample material from the asteroid Bennu. From there, the sample will be divided for study among scientists—most of whom aren't even alive today. While some of the prized space dirt and rock will immediately find its way to over 30 science and research facilities worldwide, almost three-quarters of the sample will be preserved for future generations of "scientists not yet born, using technologies not yet invented, to answer fundamental questions about the solar system," according to NASA.
