Hey everybody, welcome back to the Elon Musk podcast. This is a show where we discuss. The critical. Crossroads, The Shape, SpaceX, Tesla X, The Boring Company, and Neuralink. And I'm your host Will Walden if you want uninterrupted episodes of the Elon Musk podcast. Please go to club. Elon.supercast.com to find out how. There's a link.
In the show notes. Scientists have recently started on the groundbreaking analysis of sample from the asteroid Bennu, courtesy of NASA's OSIRIS Rex mission. This is spanned 7 years, culminating with the delivery of a precious cargo of asteroid fragments to Earth on September 24th, 2023. The landing is in a secluded area of the Utah Test and Training Range operated by the Department of Defense, and it went off without a hitch.
Now OSIRIS Rex, an acronym encapsulating the mission's multifaceted goals, has returned with what is believed to be remnants from the dawn of our own solar system some 4.5
billion years ago. And the University of Arizona's dedicated team is at the forefront, employing cutting edge technology to decipher the secrets held by these dark particles from Bennu. With the modest 200 milligrams of the Bennu sample to work with, the team has identified over 1000 particles, some as large as 3.5 centimeters, offering an unprecedented glimpse into the building blocks
of our solar system. Now these samples are teeming with minerals containing water alongside a wealth of carbon, nitrogen, sulfur and phosphorus, making them a significant repository of primordial material. And the implications of these findings are profound, hinting at Bennu's potential origins from an ancient oceanic world, a theory supported by the presence of a unique phosphate crust in the samples, a feature not found in any meteorites on Earth.
Now, as the scientific community awaits and anticipates the detailed revelations of the upcoming 55th Lunar and Planetary Science Conference, the research conducted paves the way for a deeper understanding of our place in the cosmos. This journey not only unravels the history of Bennu, but also bridges the gap between known meteorites and their celestial origins, enriching our knowledge of the vast asteroid belt and the samples from the asteroid Bennu through NASA's Osiris Rex
mission suggest. That this. Space rock might have connections to ancient ocean worlds. This discovery provides a unique glimpse into the early solar systems composition and the materials that formed our own planet. The University of Arizona's team is at the forefront analyzing the samples to uncover the secrets.
The samples are now under meticulous examination to understand their composition and significance, and at the University of Arizona Quiper, Arizona Laboratory for Estro Materials analysis, scientists are busy investigating the Bennu samples. The initial batch for analysis consists of 200 milligrams of material which, although small in quantity, is rich in data. The samples feature a variety of particle sizes, indicating A diverse collection of materials
from the asteroid. Now, the Bennu samples have revealed the wealth of information, including the presence of water, carbon, nitrogen, sulphur and also
phosphorus. These elements, which are all essential for life, are locked within the asteroid's minerals, suggesting that Bennu could be a reservoir of primordial material untouched by the processes that have altered similar substances on Earth. Now we're waiting for this analysis, and it'll happen on the 55th Lunar and Planetary Science Conference, and there's over 70 abstracts submitted for
this. The conference promises to shed new light on the asteroid's composition and its implications for understanding the solar system's history. Now 1 Intriguing aspect of the Bennu samples is the unique isotopic composition setting them apart from meteorites found on Earth. And this distinction suggests that the asteroid contains materials not typically accessible through meteorite study. Offering new avenues for research into the Solar System's building blocks are particularly novel.
Finding is the presence of a phosphate crust in Bennu samples, a feature not observed in meteorites. This crust could indicate a connection to extraterrestrial ocean worlds where phosphates play a crucial role in biological processes. This discovery fuels speculation that Bennu may have originated from an ancient ocean world. Now, the process of studying the Bennu samples is a testament to the dedication and collaboration with scientists over decades.
From the mission's proposal to the analysis of the return samples, researchers like Thomas Zega express gratitude for opportunity to contribute and participate in this groundbreaking work. In the success of Osiris Rex mission and the analysis of the Bennu samples show that this is
an important space mission. They not only enhance our understanding of scientific and specific celestial bodies, but also help connect the dots between different Astro materials found on Earth and their origins far away in the cosmos. The opening of the sample return capsule was monumentous for the Quick Look team. Revealing a fine grain dust coating from Bennu was
absolutely amazing. This initial examination set the stage for the detailed analysis that would follow using some of the most advanced analytical tools available. Now Zaga's personal journey with the Bennu samples from Texas to Arizona highlights this meticulous care taken to preserve these precious materials.
The samples were transported under strict conditions to ensure their integrity, and with the full opening of the TAG Sam head which held the Bennu samples, there's a lot of challenges and excitement inherit in space exploration. There's a lot of discovery to be happening right now and despite technical hurdles from the team, they were a part of the TAG Sam that was stuck. The team's persistence paid off, allowing for a comprehensive cataloging of the Asteroids
bounty. Now, the upcoming release of more Bennu sample catalog will mark a significant milestone, enabling scientists worldwide to request samples for their own research. Now, this effort will broaden the scope of Bennu's study, contributing to a more nuanced understanding of the asteroid and its place in our solar
system's history. And the analysis of Bennu samples is an interdisciplinary endeavor, involving a range of sophisticated instruments, from optical and electron microscopes to the cutting edge nano Sims. The team is equipped to delve into the minutiae of the asteroids composition. The insight schemes from the Bennu samples are poised to revolutionize our understanding of our own early solar system.
By examining the isotopic variations in mineral content of the asteroid, scientists can piece together the history of these ancient materials and their journey through space. The ongoing study of the Bennu samples is dynamic and it's evolving, with new discoveries expected in the coming months. And we'll have them here for you on this show, so please hit the subscribe button so you can get them all.
And the dedicated efforts of scientists ensure that this mission will continue to unfail mysteries of the cosmos for decades to come. Now, this Osiris Rex mission and the study of the Bennu samples are all about exploration and
discovery. As researchers continue to analyze these ancient materials, they're writing a new chapter in our understanding of the universe and our place within it. And the analysis of the asteroid Bennu samples offers a fascinating glimpse into the building blocks of our own solar system. The findings from these studies not only enhance our knowledge of Bennu, but also contribute to our broader understanding of the cosmos and the origins of life on Earth.
