Solving Asteroid Bennu’s Mysteries
These X-ray computed tomography (XCT) scans released on March 17, 2026, give us a glimpse inside asteroid Bennu. They show the most common types of crack networks observed in Bennu samples; these networks solved a mystery that baffled NASA for years. When NASA’s OSIRIS-REx spacecraft first approached asteroid Bennu in 2018, scientists expected to see smooth, sandy beach-like surfaces. Instead, they found a celestial body covered…

Asteroid Bennu’s Rugged Surface Baffled NASA, We Finally Know Why
In one of the biggest surprises of NASA’s OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier observations from Earth-based instruments had indicated. “When OSIRIS-REx got to Bennu in 2018, we were surprised by what we saw,” said Andrew Ryan, a scientist with…

NASA’s Bennu Samples Reveal Complex Origins, Dramatic Transformation
Asteroid Bennu, sampled by NASA’s OSIRIS-REx mission in 2020, is a mixture of dust that formed in our solar system, organic matter from interstellar space, and pre-solar system stardust. Its unique and varied contents were dramatically transformed over time by interactions with water and exposure to the harsh space environment. These insights come from a trio of newly published papers…

NASA’s Asteroid Bennu Sample Reveals Mix of Life’s Ingredients
Lee esta nota de prensa en español aquí. Studies of rock and dust from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft have revealed molecules that, on our planet, are key to life, as well as a history of saltwater that could have served as the “broth” for these compounds to interact…

NASA to Brief Media on Asteroid Sample Mission Findings
NASA will brief media at 11 a.m. EST Wednesday, Jan. 29, to provide an update on science results from NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) mission, which delivered a sample of asteroid Bennu to Earth in September 2023. Audio of the media call will stream live on the agency’s website. Participants in the teleconference include:…

NASA Shares Asteroid Bennu Sample in Exchange with JAXA
As part of an asteroid sample exchange, NASA has transferred to JAXA (Japan Aerospace Exploration Agency) a portion of the asteroid Bennu sample collected by the agency’s OSIRIS-REx mission. The sample was officially handed over by NASA officials during a ceremony on Aug. 22 at JAXA’s Sagamihara, Japan, campus. The signature exchange for the Bennu sample transfer took place on…

Revisiting OSIRIS-REx
An OSIRIS-REx sample return capsule training model parachutes down in this image from Aug. 30, 2023. This drop test was part of NASA’s preparations for the return of samples from the asteroid Bennu on Sept. 24, 2023. OSIRIS-REx was the first U.S. mission to collect a sample from an asteroid. This photo was chosen by the NASA HQ photo team as one of the…

NASA’s OSIRIS-APEX Unscathed After Searing Pass of Sun
Mission engineers were confident NASA’s OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification – Apophis Explorer) spacecraft could weather its closest ever pass of the Sun on Jan. 2, 2024. Their models had predicted that, despite traveling 25 million miles closer to the heat of the Sun than it was originally designed to, OSIRIS-APEX and its components would remain safe. The mission…

NASA’S OSIRIS-REx Curation Team Reveals Remaining Asteroid Sample
The astromaterials curation team at NASA’s Johnson Space Center in Houston has completed the disassembly of the OSIRIS-REx sampler head to reveal the remainder of the asteroid Bennu sample inside. On Jan. 10, they successfully removed two stubborn fasteners that had prevented the final steps of opening the Touch-and-Go-Sample-Acquisition-Mechanism (TAGSAM) head. Erika Blumenfeld, creative lead for the Advanced Imaging and Visualization of…

NASA Improves GIANT Optical Navigation Technology for Future Missions
Goddard’s GIANT optical navigation software helped guide the OSIRIS-REx mission to the Asteroid Bennu. Today its developers continue to add functionality and streamline useability for future missions. As NASA scientists study the returned fragments of asteroid Bennu, the team that helped navigate the mission on its journey refines their technology for potential use in future robotic and crewed missions. The optical navigation…
