TUCSON, Ariz. — On Wednesday, Oct. 11, NASA will host a news conference to unveil the asteroid material collected by the University of Arizona-led OSIRIS-REx mission. During the event, the science team will discuss an initial analysis of the sample, which is expected to land on Sunday, Sept. 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:
- Dante Lauretta, OSIRIS-REx principal investigator and Regents Professor of Planetary Sciences at the UArizona Lunar and Planetary Laboratory
- 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, Maryland
Media on-site will have the opportunity to interact with subject matter experts and see the sample live (via video feed) from the curation laboratory.
Touchdown at the Department of Defense's Utah Test and Training Range near Dugway, Utah, on Sept. 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, Sept. 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 Oct. 11.
NASA built a new 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, including those from UArizona. The UArizona-led science team will receive 25% of the sample, some of which will be studied in the university's Kuiper-Arizona Laboratory for Astromaterials Analysis. A portion of the sample will also be reserved for research decades from now, utilizing technologies that will improve over the years.
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. The sample can also reveal more about the characteristics of potentially hazardous near-Earth asteroids like Bennu, which can inform planetary defense strategies.
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.
