Download recorded audio from this media teleconference. (Right-click and select "Save Link As...").NASA is hosting a media teleconference at 3 p.m. EDT Thursday, Sept. 24, to provide an update on the agency’s first attempt to contact the surface of asteroid Bennu and collect a sample next month.The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft will travel to the asteroid’s surface during its first sample collection attempt Oct. 20. Its sampling mechanism will touch Bennu’s surface for several seconds, fire a charge of pressurized nitrogen to disturb the surface, and collect a sample before the spacecraft backs away.Participating in this mission update are:•Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate•Lori Glaze, director of NASA's Planetary Science Division•Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson•Mike Moreau, OSIRIS-REx deputy project manager at NASA’s Goddard Space Flight Center•Sandra Freund, OSIRIS-REx mission operations manager at Lockheed Martin SpaceFor more information, go to nasa.gov/osiris-rex or asteroidmission.org.

The OSIRIS-REx spacecraft uses this map to autonomously detect surface hazards, such as boulders or rocks, while it descends to collect a sample. The green illustrates areas that are free of hazards, and means the spacecraft will continue to the surface. Yellow demonstrates cautionary areas, and red areas contain the most hazards. If the spacecraft predicts it will touch either a yellow or red area, it will stop its descent and back away.Credit: NASA/Goddard/University of Arizona 4.

Lauretta – Bennu Revealed GraphicCredit: NASA/Goddard/University of Arizona NASA hosted a media teleconference at 1:30 p.m. EDT Tuesday, March 19, to announce new science from the agency’s first mission to return to Earth an asteroid sample that may contain unaltered material from the very beginning of our solar system.The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft launched Sept. 8, 2016, and began orbiting the asteroid Bennu on Dec. 31, 2018. Since its arrival at Bennu, the probe has been investigating the asteroid and searching for an ideal site for sample collection. Bennu is only slightly wider than the height of the Empire State Building and is the smallest body ever orbited by spacecraft. Studying Bennu with OSIRIS-REx will allow researchers to learn more about the origins of our solar system, the sources of water and organic molecules on Earth, and the hazards and resources in near-Earth space.

This video shows the OSIRIS-REx spacecraft’s view of Bennu during the final phase of its journey to the asteroid. From Aug. 17 through Nov. 27 the spacecraft’s PolyCam camera imaged Bennu almost daily as the spacecraft traveled 1.4 million miles (2.2 million km) toward the asteroid. The final images were obtained from a distance of around 40 miles (65 km). During this period, OSIRIS-REx completed four maneuvers slowing the spacecraft’s velocity from approximately 1,100 mph (491 m/sec) to 0.10 mph (0.04 m/sec) relative to Bennu, which resulted in the slower approach speed at the end of the video.Credit: NASA/Goddard/University of Arizona This series of images taken by the OSIRIS-REx spacecraft shows Bennu in one full rotation from a distance of around 50 miles (80 km). The spacecraft’s PolyCam camera obtained the thirty-six 2.2-millisecond frames over a period of four hours and 18 minutes.Credit: NASA/Goddard/University of Arizona After traveling through space for more than 2 years and over 2 billion kilometers, NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at its destination, asteroid Bennu, on Monday, Dec. 3, 2018. The spacecraft will spend almost a year surveying the asteroid with five scientific instruments with the goal of selecting a location that is safe and scientifically interesting to collect the sample. OSIRIS-REx will return the sample to Earth in September 2023. For More InformationSee [NASA.gov](https://www.nasa.gov/feature/goddard/2018/osiris-rex-approach) Related pages

The OSIRIS-REx mission design includes complex trajectories, polar orbits, and reconnaissance flyovers that will allow the spacecraft to thoroughly explore asteroid Bennu.Music provided by Killer Tracks: Electric Cosmos, Inducing Waves, Newfound Lands, Crystal Sound Bath, ImperatumWatch this video on the NASA Goddard YouTube channel.Complete transcript available. OSIRIS-REx is the third mission in NASA’s New Frontiers Program. Its goal is to explore near-Earth asteroid Bennu, a remnant from the dawn of the solar system, and to return a sample of Bennu to Earth. OSIRIS-REx launched on September 8, 2016, and arrived at asteroid Bennu on December 3, 2018. The spacecraft is spending more than a year surveying and mapping Bennu before collecting a sample, ensuring that it can safely descend to the asteroid’s surface and retrieve a sample of high science value.This video illustrates the OSIRIS-REx mission design in detail, through artist concept animations, data visualizations, launch footage, and imagery from the spacecraft itself. Each phase of the mission is depicted, from launch through sample return, providing an in-depth look at this journey to Bennu and back.

Asteroids are the leftover building blocks of the solar system. These remnants from the dawn of planet formation may have delivered organics and water to early Earth, and could even hold clues to the origins of life. Now, a NASA mission called OSIRIS-REx has arrived at near-Earth asteroid Bennu. It will map and study the small body in great detail, and return a piece of Bennu to Earth in 2023. The discoveries of OSIRIS-REx will shed light on our solar system’s ancient history, and help pave the way for future exploration of other small bodies.
