Although these discoveries do not confirm the existence of life itself, they provide compelling evidence of the molecules life uses to build itself. This strengthens the theory that materials essential for life were delivered to earth by asteroids like Bennu.
Scientists also uncovered clay and salt water, substances that form only when water evaporates slowly. These findings shed light on the history of water in the solar system and its interaction with molecules necessary for life.
“Asteroids provide time capsules into the history of our home planet, and bennu samples are very vital in our understanding of any material in our solar system that existed before life begins on Earth,” said Nicky Fox, Associate Administrator of the Science Mission directorate at NASA Headquarters.
Bennu: A Glimpse into the Early Solar System
Bennu, like other asteroids, offers a pristine window into the early solar system. Untouched by the complex processes that shape planets and moons, it reveals the raw materials that existed billions of years ago.
In addition to the 14 biological amino acids, Bennu’s sample contains 19 non-biological amino acids and five nucleotide bases that form RNA and DNA. Researchers also discovered significant amounts of ammonia, which reacts with formaldehyde—also found in Bennu—to produce amino acids. This provides a clear picture of how these essential molecules formed.
“Data from OSIRIS-REx provides a big picture of the solar system full of life potential,” said Dworkin, a key scientist involved in the mission.
Other Key Discoveries
another major finding is the presence of salty material formed when water evaporates. This suggests that Bennu’s parent asteroid likely formed from the accumulation of ice and rock.At some point, the ice melted, providing the water needed to form many of the materials found in Bennu.
The discovery of salt water also indicates that evaporation occurred, offering insights into the dynamic processes that shaped Bennu and similar asteroids.

A New Chapter in Space Exploration
The OSIRIS-REx mission has opened a new chapter in our understanding of the solar system’s origins and the potential for life beyond Earth. Bennu’s sample is not just a collection of rocks and dust—it’s a treasure trove of clues about how life might have begun.
As scientists continue to analyze these materials, the possibilities for discovery are endless. Bennu’s secrets are just beginning to unfold, promising to reshape our understanding of the universe and our place within it.

Water is essential for life as we know it. But what happens when water disappears? According to recent findings, its absence can trigger unique chemical processes that create materials perhaps absorbed by life. This revelation is just one of the many insights emerging from the OSIRIS-REx mission, which successfully collected samples from the asteroid Bennu and returned them to Earth.
The Challenge of Sample Return Missions
The OSIRIS-rex mission faced a monumental task: retrieving samples from Bennu and transporting them back to Earth.However, the challenge didn’t end there. Scientists had to ensure that Earth’s atmosphere didn’t contaminate the precious cargo. As Tim McCoy, a meteorite curator at the Smithsonian National Museum of Natural History, explained, “Especially when studying the history of water, any water vapor contamination will make their research unfeasible.”
To preserve the integrity of the samples, they were removed from the spacecraft in a clean glove box, shielded from outside air. The container was then filled with nitrogen, an inert gas, to prevent contamination. These samples are now distributed across multiple institutions, ensuring that no single accident could destroy all of them.
Lessons from Apollo: The Importance of Careful Curation
The Apollo missions to the Moon set a precedent for sample preservation. Over 50 years later, scientists are still conducting experiments on lunar samples, thanks to meticulous curation. Jason Dworkin, OSIRIS-REx project scientist, emphasized that most of Bennu’s samples remain unexplored. With the same level of care as the Apollo samples, scientists anticipate groundbreaking discoveries in the coming decades.
Danny Glavin, a co-author of the study, highlighted the importance of contamination control: “The instructions we are looking for are very small and easily destroyed or changed due to exposure to the Earth’s habitat.That is why some of these new discoveries will not be possible without the mission of returning samples, careful control of contamination, and curation and careful storage of the valuable material from Bennu.”
The Mystery of Left-Handed Life
One of the most intriguing questions raised by Bennu’s samples revolves around the “handedness” of molecules. Many molecules are chiral, meaning they can exist in two mirror-image forms: left-handed or right-handed. Life on Earth overwhelmingly prefers left-handed molecules, but scientists don’t know why.
Bennu’s samples contain an equal number of left and right-handed molecules, challenging the assumption that ancient asteroids delivered a preference for left-handedness to earth. This discovery deepens the mystery of why life evolved to favor one form over the other.
Key Insights from Bennu’s Samples

| Sample Collection | OSIRIS-REx mission retrieved samples from Bennu, ensuring no contamination. |
| Preservation | Samples stored in nitrogen-filled containers to prevent exposure to air. |

| Scientific Potential | Unexplored samples could yield discoveries for decades.|
| Chiral Molecules | Equal left and right-handed molecules challenge theories of life’s origins. |
What’s Next for Bennu’s Samples?
The OSIRIS-REx mission has opened a new chapter in our understanding of the solar system’s history. As scientists continue to analyze Bennu’s samples, they hope to uncover clues about the origins of water and life on Earth. The mission underscores the importance of sample return missions and meticulous curation in unlocking the secrets of our cosmic past.Stay tuned as researchers delve deeper into Bennu’s mysteries, potentially rewriting the story of life itself.For more on the latest discoveries in space exploration,check out NASA’s official updates.
