GREENBELT, Md. (NASA PR) — After months grappling with the rugged reality of asteroid Bennu’s surface, the team leading NASA’s first asteroid sample return mission has selected four potential sites for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to “tag” its cosmic dance partner.
ADELAIDE, Australia (University of Adelaide PR) — Work by a team of University of Adelaide scientists to perfect metal and mineral extraction processes is bringing the possibility of mining the wealth contained within asteroids closer to reality. But science fiction won’t become fact until asteroid mining becomes economically as well as technically viable.
WASHINGTON (NASA PR) — Citizen scientists assemble! NASA’s OSIRIS-REx mission to the asteroid Bennu needs extra pairs of eyes to help choose its sample collection site on the asteroid – and to look for anything else that might be scientifically interesting.
I was able to capture this perspective by flying over Bennu's southern hemisphere (at about -40° latitude) while pointing PolyCam up to the far north. This frame shows Bennu from the equator all the way up to about 50° latitude in the northern hemisphere.https://t.co/VCGPMhoaaLpic.twitter.com/Dxzpd6E7Fd
Look at all the different types of rocks in one small area near Bennu’s south pole. You’ve got sharp rocks, fluffy-looking rocks, dark and light rocks, big and small. Over on the lower left, there are even two white rocks sitting on a dark rock. What all is going on here? 🤔 pic.twitter.com/tKmtXez9Qq
GREENBELT, Md. (NASA PR) — A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid’s surface. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain.
This trio of images acquired by NASA’s OSIRIS-REx spacecraft shows a wide shot and two close-ups of a region in asteroid Bennu’s northern hemisphere. The wide-angle image (left), obtained by the spacecraft’s MapCam camera, shows a 590-foot (180-meter) wide area with many rocks, including some large boulders, and a “pond” of regolith that is mostly devoid of large rocks.
The two closer images, obtained by the high-resolution PolyCam camera, show details of areas in the MapCam image, specifically a 50-foot (15 meter) boulder (top) and the regolith pond (bottom). The PolyCam frames are 101 feet (31 meters) across and the boulder depicted is approximately the same size as a humpback whale.
The images were taken on February 25 while the spacecraft was in orbit around Bennu, approximately 1.1 miles (1.8 km) from the asteroid’s surface. The observation plan for this day provided for one MapCam and two PolyCam images every 10 minutes, allowing for this combination of context and detail of Bennu’s surface.
The OSIRIS-REx spacecraft continues to orbit Bennu at an altitude ranging from 1.6 to 2.1 km, with an orbital period of 61 hours. The spacecraft has completed 5.5 orbits of Bennu to date. The one-way communication time from the spacecraft back to Earth is around 5.5 minutes.
On the ground, the mission held its 14th Science Team Meeting at the University of Arizona last week. This was the first science team meeting since the spacecraft’s arrival at the asteroid, which means it was also the first gathering where the entire science team was able to work with detailed Bennu data from the spacecraft.

On Dec. 29 and 31, the OSIRIS-REx spacecraft successfully completed the two maneuvers required to enter orbit about Bennu. The accurate performance of these orbit insertion maneuvers, as well as the continued accurate navigation performance since orbit insertion, allowed for the wave-off of several planned updates to the spacecraft’s orbit determination (OD). The mission’s navigation team will continue to study OD performance over the first few weeks of spacecraft orbits to further refine and predict orbital operations – which will eventually allow the team to reduce the trim burn schedule.
The first orbit of Bennu, which started on Dec. 31, ended 61.4 hours later on Jan. 3. The spacecraft will continue orbiting the asteroid through mid-February.
TUCSON (University of Arizona PR) — At 2:43 p.m. EST on December 31, while many on Earth prepared to welcome the New Year, NASA’s OSIRIS-REx spacecraft, 70 million miles (110 million kilometers) away, carried out a single, eight-second burn of its thrusters – and broke a space exploration record. The spacecraft entered into orbit around the asteroid Bennu, and made Bennu the smallest object ever to be orbited by a spacecraft.
WASHINGTON (NASA PR) — NASA welcomed a new administrator, Jim Bridenstine, deputy administrator, Jim Morhard, and chief financial officer, Jeff DeWit, in 2018. Their focus is on firmly establishing the groundwork to send Americans back to the Moon sustainably, with plans to use the agency’s lunar experience to prepare to send astronauts to Mars.
GREENBELT, Md. (NASA PR) — Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu.
GREENBELT, Md. (NASA PR) — On Dec. 3, after traveling billions of kilometers from Earth, NASA’s OSIRIS-REx spacecraft reached its target, Bennu, and kicked off a nearly two-year, up-close investigation of the asteroid. It will inspect nearly every square inch of this ancient clump of rubble left over from the formation of our solar system. Ultimately, the spacecraft will pick up a sample of pebbles and dust from Bennu’s surface and deliver it to Earth in 2023.
WASHINGTON (NASA PR) — NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union (AGU), Dec. 10-14 in Washington. NASA-related briefings will stream live on the agency’s website.
Briefing topics include: the latest findings from the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-Rex) mission to asteroid Bennu and the new Ice, Cloud and land Elevation Satellite-2 (ICESat-2) Earth-observing mission; the lingering impact of Hurricane Maria on Puerto Rico; and an update on Voyager 2 at the edge of the solar system.
Agency scientists, and their colleagues who use NASA research capabilities, also will present noteworthy findings during scientific sessions that are open to registered media.
Details on NASA presentations will be updated online throughout the week. For a complete and up-to-date schedule of briefings and media participation information, visit:
LITTLETON, Colo. (NASA PR) — NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft is scheduled to rendezvous with its targeted asteroid, Bennu, on Monday, Dec. 3 at approximately noon EST.
NASA will air a live event from 11:45 a.m. to 12:15 p.m. EST to highlight the arrival of the agency’s first asteroid sample return mission. The program will originate from OSIRIS-REx’s mission control at the Lockheed Martin Space facility in Littleton, Colorado, and will air on NASA Television, Facebook Live, Ustream, YouTube and the agency’s website. NASA TV also will air an arrival preview program starting at 11:15 a.m. EST.
OSIRIS-REx launched in September 2016 and has been slowly approaching Bennu. 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.
