NASA成功打开小行星贝努样本容器，珍贵太空岩石现身。上周，美国宇航局(NASA)终于成功打开了小行星贝努(Bennu)样本容器 TAGSAM,并于周五发布了高分辨率图像，让大家可以近距离一睹这批来自遥远太空的“珍宝”。
在这张超高分辨率的图像中，展示了 OSIRIS-REx 探测器从贝努表面刮取的尘埃和岩石，细节清晰得仿佛触手可及。可以在 NASA 网站上查看完整尺寸的版本，可以更好地放大图像，仔细研究这些来自 45 亿年前小行星的物质。OSIRIS-REx 团队成员 Lindsay Keller 曾表示，他们计划充分利用微分析技术，对这些样品进行深入研究，甚至“拆解到原子级别”。
估计有 45 亿年历史的贝努小行星可能隐藏着太阳系形成和生命初始成分在地球诞生的关键线索，科学家们已经在 TAGSAM 外部发现的材料中发现了碳和水的迹象。虽然最初目标是获取至少 60 克的贝努“风化层”，但 OSIRIS-REx 的表现远超预期，仅从容器外部就提取到了 70.3 克样本。
NASA 将在未来两年内对部分样本进行分析，其余大部分将被妥善保存，用于未来的研究和与其他科学家共享。这一重大发现有望为人类探索宇宙奥秘提供更多线索，揭示太阳系形成和生命起源的秘密。

Title: NASA’s Astonishing Discovery: 4.5 Billion-Year-Old Asteroid Bennu Reveals Clues to Earth’s Origin and Life!
Keywords: Bennu sample, NASA opens, precious space rock
Content: NASA has successfully opened the container of a sample from asteroid Bennu, revealing a precious space rock. Last week, the United States Space Administration (NASA) finally succeeded in opening the TAGSAM container of asteroid Bennu and released high-resolution images on Friday for everyone to get a close look at these “treasures” from distant space.
In this ultra-high-resolution image, the OSIRIS-REx spacecraft scraped dust and rocks from the surface of Bennu are displayed, with details so clear that they seem within reach. The full-size version can be viewed on the NASA website, which allows for better enlargement of the image and closer study of the materials from the 4.5 billion-year-old asteroid. Lindsay Keller, a member of the OSIRIS-REx team, said that they planned to make full use of microanalysis technology to conduct in-depth research on these samples and even “disassemble down to the atomic level”.
The estimated 4.5 billion-year-old asteroid Bennu may contain key clues to the formation of the solar system and the initial components of life on Earth. Scientists have already found signs of carbon and water in the materials discovered outside the TAGSAM container. Although the initial goal was to obtain at least 60 grams of Bennu’s “weathering layer”, the OSIRIS-REx performance exceeded expectations, with a total of 70.3 grams of samples extracted from just outside the container.
NASA will analyze some of the samples over the next two years, while the rest will be carefully preserved for future research and sharing with other scientists. This major discovery is expected to provide more clues for human exploration of the mysteries of the universe, revealing secrets about the formation of the solar system and the origin of life.
