Significance of the OSIRIS-REx Mission
The OSIRIS-REx mission aimed to collect samples from the near-Earth asteroid Bennu, considered a potentially hazardous asteroid. This mission was designed not only to retrieve material but also to analyze its organic compounds, which date back over four billion years, offering insights into the early solar system. Researchers collected about 120 grams of asteroid material, which exceeded their initial goals and is deemed a valuable resource for extensive scientific analysis in the future. The mission was a culmination of over two decades of efforts to understand the origins of life and the significance of carbon-rich asteroids.
