Amino Acids Formed in Freezing Space on Bennu, Hinting at Life's Beginnings Beyond Water

NASA’s analysis of asteroid Bennu’s samples shows amino acids formed in frigid conditions long before the asteroid’s current orbit, with 14 of Earth’s 20 standard amino acids detected and evidence that left‑ and right‑handed forms carry different nitrogen isotopes. This challenges the idea that liquid water is always needed for amino‑acid formation, suggesting prebiotic chemistry could occur in more environments and expanding potential habitats for life in the universe, while signaling new questions about chirality in biology.

NASA's Asteroid Samples Rewrite Early Solar System History

NASA's OSIRIS-REx mission has returned samples from the asteroid Bennu, providing new insights into the early solar system. The samples reveal that Bennu is a fragment of a larger, ancient, carbon-rich asteroid, containing essential building blocks of life such as phosphates and amino acids. These findings could help scientists understand the origins of life and the early stages of solar system evolution. The mission's success is detailed in Dante Lauretta's book, "The Asteroid Hunter."

"Uncovering Origins: NASA's Billion-Dollar Mission to Intercept Massive Asteroid Threat"

Dante S. Lauretta's book "The Asteroid Hunter" recounts the ambitious OSIRIS-REx mission to study and collect a sample from the near-Earth asteroid Bennu, shedding light on the fragility and interconnectedness of life and celestial bodies. While the mission faced challenges and surprises, the return of Bennu's unaltered carbon silt provides a time capsule of our solar system's early days, offering insights into the origins of life on Earth and the shared cosmic heritage of all existence.

"Asteroid Bennu: Unveiling Life's Building Blocks and Rare Minerals in New Analysis"

NASA's OSIRIS-REx mission has made a groundbreaking discovery with the sample it collected from asteroid Bennu, revealing the presence of carbon, water, and minerals never before seen on Earth. This suggests that the building blocks of life on Earth might be found in this extraterrestrial rock, providing unprecedented insight into the origins of life and the early solar system. While scientists are excited about these findings, they also caution about Bennu's classification as a potentially hazardous asteroid and emphasize the need to continue tracking and understanding such near-Earth objects.

"NASA's Billion-Dollar Mission: Stopping an Empire State Building-Sized Asteroid"

An asteroid larger than the Empire State Building, named 101955 Bennu, is on a potential collision course with Earth, prompting Nasa to take action. Nasa has hired Dante Lauretta to lead a mission to research, chart, and sample the asteroid, which could cause catastrophic damage upon impact. The OSIRIS-REx mission has already returned a sample of Bennu to Earth, and Nasa is also developing technology for planetary defense, including the upcoming Dart mission.

"Bennu: A Potentially Hazardous Asteroid with Unique Minerals and Life-Building Blocks, Revealed in Comprehensive Analysis"

Scientists have revealed the intriguing composition of asteroid Bennu, which was sampled by NASA's OSIRIS-REx spacecraft. The asteroid contains a surprising reservoir of a rare mineral called magnesium phosphate, as well as glycine, water-bearing minerals, and other organic and hydrated minerals. The samples also show evidence of space weathering and impact-related breccias, supporting the theory that Bennu broke off from a larger asteroid about 2 billion to 700 million years ago. The analysis of the samples is still ongoing, but the findings provide valuable insights into the history and composition of this near-Earth asteroid.

"Close Encounters: 5 Building-Size Asteroids Set to Pass Earth"

A building-sized asteroid, 2024 CJ8, will pass by Earth tonight, coming within 4.1 million miles of the planet, but poses no threat. NASA classifies asteroids larger than 492.126 feet and within 4.6 million miles as "potentially hazardous," but this one doesn't meet the size requirement. More than 1.3 million asteroids are estimated in the solar system, and NASA has been increasing efforts to protect Earth from potential asteroid impacts, including the recent OSIRIS-REx mission. Additionally, smaller asteroids 2024 EQ and 2024 EK4 are also expected to pass by Earth this weekend.

"NASA's OSIRIS-REx Mission: Double the Expected Asteroid Rubble Sample"

NASA's OSIRIS-REx spacecraft collected a surprising 4.3 ounces (122 grams) of material from the asteroid Bennu, potentially containing some of the earliest precursors for life. The sample, the first ever retrieved by a NASA mission, was initially hindered by stuck fasteners on the capsule, but after disassembly, scientists managed to retrieve the full amount. The material, dating back 4.5 billion years, may hold primordial elements that contributed to the origins of life on Earth, similar to findings from the asteroid Ryugu.

"NASA's Sample Return from Asteroid Bennu: Potential Seeds of Life"

NASA's OSIRIS-REx spacecraft collected a surprising 4.3 ounces (122 grams) of rocky space rubble from the asteroid Bennu, more than double the expected amount, potentially containing some of the earliest precursors for life. After encountering difficulties disassembling the capsule, scientists managed to retrieve the full sample, which includes 4.5 billion-year-old rocks and primordial elements believed to have sparked life on Earth. This marks the first time a NASA mission has retrieved a space rock, and researchers are hopeful for finding biological precursors within the sample.
