Unlocking the Secrets of Life from a Watery World: NASA's Returned Asteroid SamplesAs paleontologists, we are always fascinated by the mysteries of life on Earth. The recent return of samples from near-Earth asteroid Bennu by NASA's OSIRIS-REx spacecraft has provided us with a unique window into the early days of our solar system. In this blog post, we will delve into the findings and explore how these samples hold the ingredients of life from a watery world.The Building Blocks of LifeAsteroid samples collected by NASA's OSIRIS-REx spacecraft contain not only the building blocks for life but also the salty remains of an ancient water world. The findings provide strong evidence that asteroids may have planted the seeds of life on Earth and that these ingredients were mingling with water almost right from the start.The Environment That Fostered Life"The kind of environment that could have been essential to the steps that lead from elements to life," said Tim McCoy, a lead study author at the Smithsonian Institution. This environment, characterized by sodium-rich minerals and brines, is reminiscent of what we find in dry lakebeds on Earth.The Discovery"This discovery was only possible by analyzing samples that were collected directly from the asteroid then carefully preserved back on Earth," said Yasuhito Sekine, an expert at the Institute of Science Tokyo. The OSIRIS-REx spacecraft returned 122 grams (4 ounces) of dust and pebbles from Bennu, delivering the sample canister to the Utah desert in 2023.The Findings: Amino Acids, Nitrogen, and Genetic CodeSmall amounts of Bennu's precious black grains were doled out to two separate research teams whose studies appeared in the journals Nature and Nature Astronomy. The findings confirm the presence of: Amino acids Nitrogen in the form of ammonia Parts of the genetic codeA Pathway to Life"Combining the ingredients of life with an environment of sodium-rich salt water, or brines, that's really the pathway to life," said McCoy. "These processes probably occurred much earlier and were much more widespread than we had thought before."The Significance of NitrogenOne of the biggest surprises was the relatively high abundance of nitrogen, including ammonia, said NASA's Daniel Glavin. This finding is significant because it suggests that life may have emerged in a watery environment.Bennu: A Rubble Pile with an Extensive Underground NetworkBennu, a rubble pile just one-third of a mile (one-half of a kilometer) across, was originally part of a much larger asteroid that got clobbered by other space rocks. The latest results suggest this parent body had an extensive underground network of lakes or even oceans.The Road AheadWhile the findings are exciting, scientists stress more testing is needed to better understand the Bennu samples, as well as more asteroid and comet sample returns. China plans to launch an asteroid sample return mission this year.A Mission to Collect Rocks and Dirt from CeresMany are pushing for a mission to collect rocks and dirt from the potentially waterlogged dwarf planet Ceres in the main asteroid belt. Jupiter's moon Europa and Saturn's moon Enceladus also beckon as enticing water worlds.The OSIRIS-REx Mission: A Step Towards Understanding LifeMost of the OSIRIS-REx mission's cache has been set aside for future analysis. Scientists are eager to continue exploring the secrets hidden within the asteroid samples.The Future of Paleontology: Uncovering the Secrets of LifeAs we move forward, it's clear that our understanding of life on Earth is closely tied to the study of asteroids and comets. By analyzing these samples, we can gain insights into the origins of life and the potential for life beyond our planet.In conclusion, NASA's returned asteroid samples hold the ingredients of life from a watery world, providing us with a unique window into the early days of our solar system. As paleontologists, it's essential that we continue to explore these findings and push the boundaries of what we know about the origins of life on Earth.References:1. NASA (2023).

Enjoy the little things in life. For one day, you may look back and realize they were the big things. Many of life's failures are people who did not realize how close they were to success when they gave up.
