OSIRIS-REx – Detailed Global Views of Asteroid Bennu

This visualization begins with a top-down view of a high resolution digital terrain model (DTM) of the Nightingale TAG sample site on Bennu. As the camera moves closer, data representing the surface height change pre-post TAG fades on. The surface height change as a result of the TAG event is represented by both a color map and by offsetting the original DTM to reveal the TAG crater. The DTM offset is applied to the surface region within ~7.5 meters of impact, which is highlighted for emphasis. With this color bar, yellows, greens, and blues represent a decrease in elevation, light red represents no change in elevation, and dark red represents an increase in elevation. Thruster marks and a region of ejected surface material are labeled. The camera does a 360 degree spin around the sample site before returning to a top-down view of the color-mapped data.

The Origins Spectral Interpretation Resource Identification Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at near-Earth asteroid Bennu in December 2018. After studying the asteroid for nearly two years, the spacecraft successfully performed a Touch-And-Go (TAG) sample collection maneuver on October 20, 2020. The change in surface topography as a result of the sample collection maneuver is observed by comparing pre-TAG and post-TAG digital terrain models (DTM), revealing the newly-formed TAG crater. OSIRIS-REx will return its sample of Bennu to Earth in September 2023. Related pages

Visualization depicting the 2135 Bennu-Earth flyby. Bennu’s orbit is represented in white. Earth’s orbit is represented in light blue. Visualization depicting the 2182 Bennu-Earth flyby. Bennu’s location in 2182 will vary depending on how the 2135 flyby occurs. Two representations of Bennu are depicted. The white dot represents an Earth-miss and the grey dot represents an extremely unlikely (1:2700 or 0.037% chance) Earth impact. Earth’s orbit is represented in light blue. On September 25, 2135, an asteroid called Bennu will make a close flyby of Earth. Our planet’s gravity will tweak Bennu’s path, making it a challenge to calculate its future trajectory. During the flyby, there is an extremely small chance that Bennu will pass through a “gravitational keyhole” – a region of space that would set it on just the right path to impact Earth, late in the 22nd century. Although it is difficult to determine the odds of this actually happening, new data from NASA’s OSIRIS-REx spacecraft have allowed scientists to better model how Bennu’s orbit will evolve over time, and to better calculate the probability of an impact. Now, a new paper from the OSIRIS-REx science team gives Bennu a 1:2700 (0.037%) chance of impacting Earth on September 24, 2182. Related pages

Associated b-roll will be added by Friday May 7 by 5:00 p.m. EDT B-ROLL for live shot interviews. TRT of 4:58 NASA’s First Asteroid Sample Return Mission Preparing for Critical Maneuver to Head Back to Earth NASA’s OSIRIS-REx spacecraft is on its way back to Earth! After almost two and a half years (two years, five months and eight days to be exact!) of operations at asteroid Bennu, the spacecraft is ready to come home carrying a bounty of asteroid material in its capsule. But first, the spacecraft will need to perform another flawless maneuver for a successful departure. There is no straight path back to Earth. Like a quarterback throwing a long pass to where a receiver will be in the future, OSIRIS-REx is traveling to where the Earth will be in the future. The spacecraft has to go around the sun twice, covering 1.4 billion miles (2.3 billion kilometers) over 2.5 years to catch up with Earth. NASA experts are available virtually for live or taped interviews on May 10 from 6:00 a.m. to 1:00 p.m. EDT - the morning of this historic maneuver - to tell your viewers how they can watch the event unfold, and what scientists hope to learn from this out-of-this-world sample from a nearby asteroid. In 2016, NASA launched OSIRIS-REx on an epic mission to capture a sample of an asteroid and bring it back to Earth. On October 20, 2020, the spacecraft descended to the boulder-strewn surface of Bennu to a site called Nightingale, where the spacecraft’s robotic sampling arm snagged so much sample that it overflowed the collection system. There are more than a million known asteroids in our solar system, but Bennu is an ideal candidate for closer study because of its size, composition and proximity to Earth. Bennu is an artifact of the ancient solar system, a silent witness to the titanic events in our solar system’s 4.6 billion-year history.

This visualization depicts the OSIRIS-REx TAG on October 20, 2020. The OSIRIS-REx satellite is represented by an orange dot and trail. The visualization begins with the satellite’s departure from orbit and continues through the checkpoint, matchpoint, TAG, and backaway maneuvers. This is a closer view of the TAG, focusing on the checkpoint, matchpoint, TAG, and backaway maneuvers. White labels appear to highlight checkpoint and matchpoint. The TAG location is indicated with a marker that changes from white to green once the TAG has occurred. This a closer view of the TAG in a Bennu-fixed reference frame. A thin green line shows the future trajectory of OSIRIS-REx down to the TAG site. White labels appear to highlight checkpoint and matchpoint maneuvers. The TAG location is indicated with a marker that changes from white to green once the TAG has occurred. This is a view of the TAG event from the perspective of the OSIRIS-REx spacecraft. The visualization begins with the satellite’s departure from orbit and continues through the checkpoint, matchpoint, TAG, and backaway maneuvers. This is a view of the TAG event from the perspective of the OSIRIS-REx spacecraft. The visualization begins with the satellite’s departure from orbit and continues through the checkpoint, matchpoint, TAG, and backaway maneuvers. This version is about four times slower than the previous version and includes more of the backaway. This is a slower view of the TAG event from the perspective of the OSIRIS-REx spacecraft. The visualization begins just after the checkpoint maneuver and continues through matchpoint, TAG, and backaway. On Oct. 20, the OSIRIS-REx spacecraft will perform the first attempt of its Touch-And-Go (TAG) sample collection event. This series of maneuvers will bring the spacecraft down to site Nightingale, a rocky area 52 ft (16 m) in diameter in Bennu’s northern hemisphere, where the spacecraft’s robotic sampling arm will attempt to collect a sample. Site Nightingale was selected as the mission’s primary sample site because it holds the greatest amount of unobstructed fine-grained material, but the region is surrounded by building-sized boulders. During the sampling event, the spacecraft, which is the size of a large van, will attempt to touch down in an area that is only the size of a few parking spaces, and just a few steps away from some of these large boulders.During the 4.5-hour sample collection event, the spacecraft will perform three separate maneuvers to reach the asteroid’s surface. The descent sequence begins with OSIRIS-REx firing its thrusters for an orbit departure maneuver to leave its safe-home orbit approximately 2,500 feet (770 meters) from Bennu's surface. After traveling four hours on this downward trajectory, the spacecraft performs the “Checkpoint” maneuver at an approximate altitude of 410 ft (125 m). This thruster burn adjusts OSIRIS-REx’s position and speed to descend steeply toward the surface. About 11 minutes later, the spacecraft performs the “Matchpoint” burn at an approximate altitude of 177 ft (54 m), slowing its descent and targeting a path to match the asteroid's rotation at the time of contact. The spacecraft then descends to the surface, touches down for less than sixteen seconds and fires one of its three pressurized nitrogen bottles. The gas agitates and lifts Bennu’s surface material, which is then caught in the spacecraft’s collector head. After this brief touch, OSIRIS-REx fires its thrusters to back away from Bennu’s surface and navigates to a safe distance from the asteroid. Related pages

This first shot of the sequence begins with OSIRIS-REx’s arrival at the asteroid Bennu. A low resolution view of the asteroid is presented and thermal inertia data fades in, representing our initial understanding of the asteroid. The asteroid then spins quickly to serve as a transition to the second shot in the sequence. This second shot in the sequence begins with a fast spinning Bennu, matching the end of the first shot in the sequence. As Bennu’s rotation decelerates, a highly detailed view of the asteroid is revealed using 20cm terrain elevation data (OLA) and high resolution imagery (PolyCam). The camera then zooms in and flys over several locations - Simurgh, Roc, Gargoyle, and Ocypete. Each of these locations are presented using 5cm terrain elevation tiles. The third shot of the sequence begins with a dramatic reveal of BenBen, the tallest boulder on Bennu. The shot begins in darkness and sunlight sweeps across the surface of the asteroid. The camera rotates down to the horizon to show the height of the boulder before zooming over to a view of two boulders found to contain pyroxene. The camera then zooms back out to a global view and we see OSIRIS-REx in orbit around the asteroid. When NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu in December 2018, its close-up images confirmed what mission planners had predicted nearly two decades before: Bennu is made of loose material weakly clumped together by gravity, and shaped like a spinning top. This major validation, however, was accompanied by a major surprise. Scientists had expected Bennu’s surface to consist of fine-grained material like a sandy beach, but instead OSIRIS-REx was greeted by a rugged world littered with boulders – the size of cars, the size of houses, the size of football fields.This video explores several interesting features of Bennu. The surface features are presented in vivid detail thanks to detailed terrain data from the OLA instrument and high resolution imagery from the PolyCam instrument. Related pages

Its main science goal is to collect a sample of near-Earth asteroid Bennu for return to Earth in 2023. These animations show a size comparison of the planned sample collection area before arriving at Bennu (orange), and after arriving at Bennu (blue). The original mission plan envisioned a sample site with a diameter of 164 feet (50 m). However, the sampling region for site Nightingale is approximately 26 ft (8 m) in diameter. The area safe enough for the spacecraft to touch is the width of a few parking spaces.

After a year of studying asteroid Bennu, the OSIRIS-REx mission chose a location called “Nightingale” as the primary sample collection site.Universal Production Music: “Extreme Measures” by John Sands and Marc Ferrari, “Ice Echoes” by Dominik Luke Marsden Johnson, “Look at the Mirror” by Jonathan FigoliWatch this video on the NASA Goddard YouTube channel.Complete transcript available. Thermal map of asteroid Bennu OSIRIS-REx is a NASA mission to explore near-Earth asteroid Bennu and return a sample to Earth. Prior to arriving at Bennu, mission planners had expected the asteroid’s surface to consist largely of fine particulate material, similar to gravel. When OSIRIS-REx arrived in December 2018, however, it was greeted by a rocky world covered with boulders.This unexpected ruggedness means that there are few places on Bennu where OSIRIS-REx can safely touch down and collect a sample. After a year of studying the asteroid, the mission announced a primary sample collection site, which they designated “Nightingale,” along with a backup site called “Osprey.” In October 2020, OSIRIS-REx will descend to Bennu and attempt to collect up to four-and-a-half pounds of loose material, for return to Earth in 2023.Learn more about the selection of sample site Nightingale. In the thermal map above, asteroid Bennu’s surface temperatures dramatically change from the night side to the day side, experiencing swings of 270 degrees Fahrenheit. The time that it takes for an object to heat up or cool down is determined by its thermal inertia — a property that can be useful in the remote study of planetary bodies.Fine particulate materials like sand or gravel tend to heat up and cool down quickly (low thermal inertia), while solid objects like rocks and boulders do so more slowly (high thermal inertia). By observing how a distant body like Bennu changes temperature over the course of a day, scientists can usually infer the average size of particles on its surface.Before OSIRIS-REx arrived, scientists had observed that Bennu’s surface heats up and cools down relatively quickly, leading them to predict a mean particle size of about 2-3cm. OSIRIS-REx, however, was greeted by a predominantly rocky asteroid, littered with giant boulders. This discrepancy is one of the major surprises of the OSIRIS-REx mission.

Areas for safely touching down are fewer and smaller than anticipated, and OSIRIS-REx will have to navigate to them with unprecedented accuracy.In mid-2019, mission planners identified four candidate sample collection sites, and named them after birds that can be found in Egypt: Osprey, Kingfisher, Nightingale, and Sandpiper. In December 2019, mission planners announced that they had selected Nightingale as the primary sample collection site, and Osprey as the backup. Late in 2020, OSIRIS-REx will descend to Bennu's surface and collect a sample of pristine material from the origins of the solar system that will be studied on Earth for decades to come.The 3D animations on this page were created using laser altimetry data and imagery of Bennu taken by OSIRIS-REx.

This episode of NASA Science Live is broadcasting live from AGU in San Francisco. We have breaking news on our satellite OSIRIS-REx which is orbiting an asteroid named Bennu - and some of its mineral fragments could be older than the solar system itself. These microscopic grains of dust could be the same ones that spewed from dying stars and eventually came together to make the Sun and its planets nearly 4.6 billion years ago. And today we'll announce the site where OSIRIS-REx will attempt to collect at least 30 sugar packets worth of dirt and rocks from Bennu's surface.

Site Nightingale (top left) is located in Bennu’s northern hemisphere. Sites Kingfisher (top right) and Osprey (bottom left) are located in Bennu’s equatorial region. Site Sandpiper (bottom right) is located in Bennu’s southern hemisphere. In December 2019, one of these sites will be chosen for the mission’s touchdown event.Credit: NASA/Goddard/University of Arizona Candidate Bennu sample site - OspreyInstrument Used: OCAMS (PolyCam) Candidate Bennu sample site - KingfisherInstrument Used: OCAMS (PolyCam) Candidate Bennu sample site - NightingaleInstrument Used: OCAMS (PolyCam) Candidate Bennu sample site - SandpiperInstrument Used: OCAMS (PolyCam) Visualization of a rotating 3D model representation of the asteroid Bennu, created using data from the OSIRIS-REx Laser Altimeter (OLA) instrument.

Its primary science objective is to collect a sample of Bennu in mid 2020 and return it to Earth in late 2023. In preparation, mission planners have identified four candidate sample sites on Bennu's rocky surface where OSIRIS-REx could briefly touch down to collect its sample. The mission will down-select to the final two sites – a primary and a backup – in December 2019. Like the mythological Bennu bird for which the asteroid is named, all of the candidate sample sites refer to birds that can be found in Egypt.Learn more about the candidate sample sites on Bennu.
