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.

On December 31, 2018, OSIRIS-REx completed its Preliminary Survey of asteroid Bennu and entered into orbit. Bennu measures only half a kilometer in diameter, making it the smallest world ever to be orbited by a spacecraft. When OSIRIS-REx completes the Orbital A phase in March 2019, it will begin its Detailed Survey of Bennu.

NASA’s OSIRIS-REx mission presented the science results gained during the spacecraft’s approach toward the asteroid Bennu at a press conference hosted during AGU’s Fall Meeting at 2 p.m. ET, Monday, December 10, 2018. This page contains graphics from the press conference for download, including images of Bennu taken during approach.

After traveling through space for more than 2 years and over 2 billion miles, 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.

OSIRIS-REx will shed light on our solar system’s ancient history, and help pave the way for future exploration of other small bodies in addition to asteroid Bennu. In this short documentary, members of the OSIRIS-REx team capture the excitement of arriving at Bennu and look forward to the discoveries ahead.

This narrated 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.

This animated feature takes a fun look at how asteroid Bennu was chosen as the target for the OSIRIS-REx mission. Bennu’s size, primitive composition, and potentially hazardous orbit make it one of the most fascinating and accessible near-Earth objects, and the ideal target for the OSIRIS-REx mission.

Once OSIRIS-REx has completed its Preliminary Survey of Bennu and entered orbit, it will be ready to study the asteroid in greater detail. Its observations will help mission planners to identify candidate sample sites on Bennu – areas where it is safe to collect a sample, and which are of interest to scientists. During this phase, OSIRIS-REx will: scan Bennu from pole-to-pole, globally map its surface, take high-resolution images, and study its spectra to determine the asteroid’s mineral composition.

After launching from Earth on September 8, 2016, OSIRIS-REx spent over two years on its outbound cruise to asteroid Bennu. It approached the asteroid in August 2018 and captured the first visible-light images of Bennu using its long-range camera, PolyCam. OSIRIS-REx officially arrived at Bennu on December 3, 2018, and began studying the asteroid in preparation for sample collection in 2020.

On September 22, 2017, OSIRIS-REx approached Earth and flew over its southern hemisphere, passing within 11,000 miles of Antarctica. This gravitational slingshot bent the spacecraft's trajectory by six degrees, sending it on a path to intercept near-Earth asteroid Bennu. Shortly after the flyby, OSIRIS-REx looked back at Earth and took images and spectra, calibrating its instruments for arrival at Bennu in 2018. This page contains animations of the Earth gravity assist and OSIRIS-REx's cruise to asteroid Bennu.

On September 22, 2017, OSIRIS-REx approached Earth and flew over its southern hemisphere, receiving a gravitational slingshot from our planet in order to get to asteroid Bennu.

The OSIRIS-REx Camera Suite, or OCAMS, will provide high-resolution images of Bennu, allowing OSIRIS-REx to map the asteroid, determine its mineralogy, and even take close-up pictures of the surface at less than a centimeter per pixel. After OCAMS and its fellow instruments have thoroughly surveyed Bennu, OSIRIS-REx will carry out its most important task: collecting a sample of the asteroid for return to Earth in 2023. SamCam, the suite's wide-angle camera, will allow OSIRIS-REx to capture this dramatic event.

The OSIRIS-REx Laser Altimeter (OLA) will provide a three-dimensional map of asteroid Bennu's shape, which will allow scientists to understand the context of the asteroid's geography and the sample location. OLA is provided by the Canadian Space Agency in exchange for Canadian ownership of a portion of the returned asteroid sample.

The OSIRIS-REx Visible and Infrared Spectrometer (OVIRS) will look at asteroid Bennu's spectral signature to detect organics and other minerals. Spectral data will help mission scientists determine the best location for OSIRIS-REx to collect a sample of Bennu.

The OSIRIS-REx spacecraft carries a student-built instrument called REXIS - the Regolith X-Ray Imaging Spectrometer. The purpose of REXIS is to collect and image fluorescent X-rays emitted by asteroid Bennu, which will give scientists information regarding the atomic elements that comprise it.

College students in Boston are getting the chance to help NASA explore an asteroid. These student scientists have built an instrument called REXIS which will fly on the OSIRIS-REx spacecraft. This video puts a spotlight on a group of these students and their experience on the REXIS project.

Near-Earth asteroids like Bennu pose a potential danger to our planet, so it's important to predict their orbits with great accuracy. Unfortunately, a phenomenon called the Yarkovsky effect can make these predictions difficult over long time periods. Measuring the Yarkovsky effect at Bennu is one of the objectives of NASA's OSIRIS-REx mission.

Astrobiologists are keenly interested in the origins of life on Earth, but the evidence they seek was erased long ago by Earth’s geology and chemistry. Fortunately, asteroids like Bennu preserve the solar system’s earliest ingredients, including the carbon-based building blocks of life. Retrieving a sample of asteroid Bennu is the top priority of NASA's OSIRIS-REx mission.

Born from the rubble of a violent collision, hurled through space for millions of years, asteroid Bennu has had a tough life in a rough neighborhood - the early solar system. Bennu's Journey shows what is known and what remains mysterious about the evolution of Bennu and the planets. By retrieving a sample of Bennu, OSIRIS-REx will teach us more about the raw ingredients of the solar system and our own origins.

To answer this question, scientists are sending a spacecraft called OSIRIS-REx to explore asteroid Bennu, a survivor of our solar system's turbulent past. Follow Bennu's Journey, and learn more about our own.

What’s the best way get a sample of an asteroid? Play tag with it! That’s the plan for OSIRIS-REx, a NASA spacecraft that will approach asteroid Bennu in 2018. The spacecraft will collect a sample from the asteroid with an instrument called the Touch-And-Go Sample Acquisition Mechanism, or TAGSAM. Learn how it works in this video.

NASA is sending a spacecraft called OSIRIS-REx to explore 101955 Bennu, a near-Earth asteroid containing material from the dawn of the solar system. Scientists think that Bennu is rich in organics - the carbon-based building blocks of life - and may hold clues to the origins of the solar system and the evolution of our planet.

On February 15, 2013, a 45-meter asteroid called Duende passed within 28,000 kilometers of Earth - closer than many satellites, and the closest approach on record for an object of this size. In an effort to better understand Near Earth Objects and our planet's own origins, NASA is sending the OSIRIS-REx spacecraft to another near-Earth asteroid called Bennu. OSIRIS-REx will study the evolution of Bennu's orbit and retrieve a sample of the asteroid for return to Earth.
