NASA’s first asteroid sample return mission now knows much more about the material it’ll be collecting in just a few weeks. In a special collection of six papers published today in the journals Science and Science Advances, scientists on the OSIRIS-REx mission present new findings on asteroid Bennu’s surface material, geological characteristics, and dynamic history. They also suspect that the delivered sample of Bennu may be unlike anything we have in the meteorite collection on Earth.
A historic moment is on the horizon for NASA’s OSIRIS-REx mission. In just a few weeks, the robotic OSIRIS-REx spacecraft will descend to asteroid Bennu’s boulder-strewn surface, touch down for a few seconds and collect a sample of the asteroid’s rocks and dust – marking the first time NASA has grabbed pieces of an asteroid, which will be returned to Earth for study.
GREENBELT, Md. (NASA PR) — In an interplanetary faux pas, it appears some pieces of asteroid Vesta ended up on asteroid Bennu, according to observations from NASA’s OSIRIS-REx spacecraft. The new result sheds light on the intricate orbital dance of asteroids and on the violent origin of Bennu, which is a “rubble pile” asteroid that coalesced from the fragments of a massive collision.
HAMPTON, Va. (NASA PR) — NASA is advancing a laser-based technology designed to help spacecraft land on a proverbial dime for missions to the Moon and Mars. The technology will undergo testing on upcoming suborbital rocket launches with Blue Origin on its New Shepard rocket and ride to the Moon on several commercial landers as part of the Artemis program. Simultaneously, companies are using the technology to help self-driving cars navigate rush hour traffic on this planet.
NASA’s Planetary Science Division (PSD) faces a series of managerial, financial and personnel challenges as it prepares to conduct a series of ever more ambitious missions to the moon and planets, according to a new audit by the space agency’s Office of Inspector General (IG).
TUCSON, Ariz. (University of Arizona PR) — It’s 5 o’clock somewhere. And while here on Earth, “happy hour” is commonly associated with winding down and the optional cold beverage, that’s when things get going on Bennu, the destination asteroid of the University of Arizona-led OSIRIS-REx NASA mission.
WASHINGTON (NASA PR) — With 2020 more than half way through, NASA is gearing up for a busy rest of the year and 2021.
Following the recent successful launch of a Mars rover and safely bringing home astronauts from low-Earth orbit aboard a new commercial spacecraft, NASA is looking forward to more exploration firsts now through 2021.
Yesterday, the OSIRIS-REx spacecraft performed its final practice run of the sampling sequence, reaching an approximate altitude of 131 feet (40 meters) over sample site Nightingale before executing a back-away burn. Nightingale, OSIRIS-REx’s primary sample collection site, is located within a crater in Bennu’s northern hemisphere.

Greenbelt, Md. — NASA’s first asteroid sampling spacecraft is making final preparations to grab a sample from asteroid Bennu’s surface. Next week, the OSIRIS-REx mission will conduct a second rehearsal of its touchdown sequence, practicing the sample collection activities one last time before touching down on Bennu this fall.
TUCSON, Ariz. (University of Arizona PR) — As NASA’s OSIRIS-REx spacecraft prepares to briefly touch down and collect a sample from the asteroid Bennu in October, the mission’s science team, led by the University of Arizona, has worked meticulously to create the highest resolution global map of any planetary body, including Earth. The endeavor is the latest in the university’s long history of celestial imaging and mapping – one that began with the first lunar landings.
This view of sample site Nightingale on asteroid Bennu is a mosaic of images collected by NASA’s OSIRIS-REx spacecraft on March 3. A total of 345 PolyCam images were stitched together to produce the mosaic, which shows the site at 0.2 inches (4 mm) per pixel at full size.
These images were captured when the spacecraft performed an 820-foot (250-meter) reconnaissance pass over site Nightingale, which at the time was the closest the site had been imaged. The low-altitude pass provided high-resolution imagery for the OSIRIS-REx team to identify the best location within the site to target for sample collection.
Sample site Nightingale is located in the relatively clear patch just above the crater’s center – visible in the center of the image. The large, dark boulder located at the top right measures 43 feet (13 meters) on its longest axis. The mosaic is rotated so that Bennu’s east is at the top of the image.
Nightingale is the primary sample collection site for the OSIRIS-REx mission. OSIRIS-REx is scheduled to make its first sample collection attempt at site Nightingale on Oct. 20.
TUCSON (Planetary Science Institute PR) — Close-up observations of asteroid Bennu by NASA’s OSIRIS-REx spacecraft contain the first evidence of thermal fracturing of rocks on an airless body, a Nature Communications paper by Planetary Science Institute Research Scientist Jamie Molaro says.
