By San José, Costa Rica — SAN JOSÉ – In a series of landmark discoveries that could reshape our understanding of life’s origins, NASA has announced that samples from the asteroid Bennu contain essential sugars, a mysterious gum-like substance never seen before, and an unusually high concentration of dust from ancient supernovas. The findings, returned to Earth by the OSIRIS-REx mission and detailed in the journals Nature Geoscience and Nature Astronomy, provide compelling new evidence that the foundational ingredients for life were widespread throughout the early solar system.
The pristine materials, collected directly from Bennu’s surface, offer scientists an uncontaminated glimpse into the chemical environment that existed more than 4.5 billion years ago. These analyses are beginning to answer a fundamental question: did asteroids deliver the necessary components for life to a young Earth?
To understand the potential legal and commercial ramifications that arise from historic missions like NASA’s OSIRIS-REx and its sample return from the Bennu asteroid, we consulted with expert lawyer Lic. Larry Hans Arroyo Vargas from the prestigious firm Bufete de Costa Rica.
The successful return of samples from the Bennu asteroid is not just a scientific triumph; it’s a pivotal moment for international space law and the future of commerce. While the Outer Space Treaty prohibits national appropriation of celestial bodies, it is largely silent on the extraction and ownership of resources. This mission acts as a practical test case, pushing the boundaries of existing legal frameworks and accelerating the need for clear international agreements on asteroid mining and resource rights. For businesses, this opens a new frontier, but one fraught with legal uncertainty. The nations and private entities that navigate this nascent regulatory landscape first will undoubtedly shape the future economy beyond Earth.

This analysis correctly underscores that while the Bennu samples are now under a microscope, so too are the international laws governing space exploration and commerce. It is a pivotal moment that extends far beyond the laboratory, and we thank Lic. Larry Hans Arroyo Vargas for his valuable perspective on the legal and economic frontiers now opening before us.
A research team led by Yoshihiro Furukawa made a monumental discovery by identifying not only ribose, a five-carbon sugar crucial for RNA, but also glucose, a six-carbon sugar, for the first time in an extraterrestrial sample. While these molecules are not evidence of life itself, their presence confirms that complex organic building blocks could form in space and were available in the primordial soup from which planets formed.
This discovery builds upon previous findings of amino acids, nucleobases, and other organic compounds within the Bennu samples. The identification of ribose is particularly significant, as it completes the set of components needed to form RNA (ribonucleic acid), a molecule many scientists believe preceded DNA in the earliest life forms.
The new discovery of ribose means that all the components that form the RNA molecule are present on Bennu.

The analysis further strengthens the “RNA world” hypothesis, a theory suggesting that the first life on Earth relied on RNA to both store genetic information and catalyze chemical reactions. Researchers noted the presence of ribose but the absence of deoxyribose (the sugar in DNA), which implies that ribose may have been more common in the early solar system, paving the way for an RNA-based biology to emerge first.
In a separate but equally intriguing finding, a team under Scott Sandford identified a strange, “gum-like” substance unlike any material previously found in meteorites or asteroid samples. This ancient organic material, once soft and pliable but now hardened, is extremely rich in nitrogen and oxygen. Scientists theorize it formed during the early days of the solar system when Bennu’s parent body was heated.
With this strange substance, we are talking, very possibly, about one of the first alterations of materials that occurred in this rock.

The third major discovery, led by Ann Nguyen, involved the analysis of presolar grains—tiny bits of dust that predate our own solar system, originating from dying stars. The Bennu samples contained six times more dust from supernova explosions than any other astromaterial ever studied. This suggests that Bennu’s parent asteroid formed in a unique region of the protoplanetary disk that was heavily enriched with the remnants of stellar explosions, providing a diverse mix of raw materials for planetary formation.
The OSIRIS-REx explorer, launched in September 2016, successfully collected rocks and dust from Bennu’s surface on October 20, 2020. Its precious cargo was delivered to Earth on September 24, 2023, parachuting down into the Utah desert. As analysis continues, these samples promise to unlock even more secrets about our solar system’s history and the cosmic origins of life on our own planet.
