An asteroid sample is about to land on Earth. Here’s what to expect
—sense
When the OSIRIS-REx spacecraft swings by Earth on Sunday, it is expected to deliver a rare cosmic gift: a pristine sample collected from the near-Earth asteroid Bennu.
If all goes according to plan, the spacecraft will release a capsule containing an estimated 8.8 ounces of asteroid rocks and soil from space toward a landing zone in the Utah desert.
NASA will provide a live stream of the sample delivery beginning at 10 a.m. ET Sunday. The capsule is expected to enter Earth’s atmosphere at 10:42 a.m. ET, traveling about 27,650 miles per hour (44,498 kilometers per hour). It will land in Utah about 13 minutes later.
