NASA’s Johnson Space Center will reveal the US’s first asteroid sample from the seven-year OSIRIS-REx mission on October 11. This sample will provide insights into the solar system’s formation and the origin of life on Earth.

The first asteroid sample collected in space and brought to Earth by the United States will be unveiled at NASA’s Johnson Space Center in Houston on Wednesday, October 11, and media accreditation is now open.

NASA will host a news conference at 11 a.m. EDT (8 a.m. PDT) for the reveal, which will air live on NASA Television, the NASA app, and the agency’s website.


OSIRIS-REx is NASA’s first asteroid sample return mission. It launched in September 2016 on a journey to explore a near-Earth asteroid called Bennu. In October 2020, the spacecraft ventured to the asteroid’s surface and collected about 250 grams of material for delivery to Earth. The mission’s thrilling finale will take place on September 24, 2023, as OSIRIS-REx releases a capsule containing the Bennu samples for touchdown in the Utah desert.

During the event, NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) science team will discuss an initial analysis of the sample, which is expected to land on Sunday, September 24, in the Utah desert.

After the OSIRIS-REx spacecraft enters Earth’s atmosphere and safely lands, NASA experts will collect the rocks and dust retrieved from the asteroid Bennu inside the capsule, and bring the sample to NASA Johnson for examination in a pristine curation facility.

News conference participants include:

  • NASA Administrator Bill Nelson
  • Francis McCubbin, OSIRIS-REx deputy curation lead, NASA Johnson
  • Daniel Glavin, OSIRIS-REx sample analysis lead, NASA Goddard Space Flight Center, Greenbelt
  • Dante Lauretta, OSIRIS-REx principal investigator, University of Arizona, Tucson

A Seven-Year Journey and Beyond

Touchdown at the Department of Defense’s Utah Test and Training Range near Dugway, Utah, on September 24, will mark the end of a seven-year journey to explore the asteroid Bennu, collect a sample from its surface, and deliver it to Earth.

The next phase of the mission, which includes both curation and research activities, will kick off after the OSIRIS-REx sample return capsule arrives at Johnson on Monday, September 25. The curation team will carefully disassemble the sample container to extract the bulk of the sample and researchers will perform a first-look analysis of the sample, the results of which will be discussed for the first time on October 11.

Laboratory and Future Research

NASA has established a dedicated OSIRIS-REx Sample Curation Laboratory where curators from the Astromaterials Research and Exploration Science team will manage distribution of samples to scientists around the world over the coming years. Those scientists seek to learn more about how our planet and solar system formed, as well as the origin of organics that may have led to life on Earth. A portion of the sample will also be reserved for research decades from now, utilizing technologies that will improve over the years.

Johnson houses the world’s largest collection of astromaterials from the solar system under one roof, including samples from asteroids, comets, Mars, the Moon, Sun, and dust from other stars. Scientists use world-class laboratories to perform research on planetary materials and the space environment to investigate the origin and evolution of our solar system and beyond.
