In September 2023, a NASA spacecraft called Osiris-Rex returned to Earth, bringing back samples collected from the surface of an asteroid named Bennu. This mission marked a significant step in space exploration, as it provided scientists with physical material from an asteroid that could offer clues about the early solar system. Earlier, in 2020, Japan's Hayabusa 2 mission, conducted by the Japan Aerospace Exploration Agency (Jaxa), had successfully retrieved samples from another asteroid, Ryugu. Now, a meteorite discovered on Earth in 2024 may be linked to one of these two asteroids, offering a potential connection between the samples brought back from space and those found on our planet.
The meteorite was found by Jean Redelsperger, a French researcher, who shared his findings with the Czech science magazine Futura. Redelsperger's discovery has sparked interest among scientists who study asteroids, as it could provide a rare opportunity to compare Earth-based samples with those collected from space. This comparison might help scientists better understand the composition and history of asteroids, as well as their potential role in delivering water and organic materials to early Earth.
Brian May, the lead guitarist of the iconic rock band Queen and co-founder of Asteroid Day, a global awareness campaign about the risks and opportunities of asteroids, has worked alongside scientists to visualize asteroids in three dimensions. Using stereo pairs of asteroid images, May and his collaborators have developed detailed models that help scientists study the shape and structure of these celestial bodies. These models are crucial for understanding how asteroids form and evolve over time.
Patrick Michel, a research director at the CNRS at the Observatoire de la Côte d'Azur, has also contributed to this work. As a Principal Investigator on several international space missions, Michel uses numerical modeling to simulate the formation and evolution of asteroids. This research helps scientists predict the behavior of asteroids in space, including their potential paths and interactions with Earth. A video explaining this work is available in English with French subtitles, offering a visual and accessible introduction to the science behind asteroid studies.
