NASA向JAXA提供“贝努”小行星样本，助力揭秘地球生命起源
近日，美国国家航空航天局（NASA）向日本宇宙航空研究开发机构（JAXA）提供了去年从小行星“贝努”上采集的部分样本，引发了科学界的广泛关注。外界期待，通过对这些珍贵样本的分析，能够获得地球生命起源、太阳系诞生等多个领域的全新科研成果。
“贝努”是一颗运行轨道位于地球和火星之间的小行星，美国国家航空航天局的小行星采样探测器“奥西里斯-REx”于2020年抵达“贝努”，并利用机械臂成功采集了尘埃等121.6克的样本。样本仓于去年9月返回地球，为科学家们带来了来自宇宙深处的宝贵礼物。
根据NASA与JAXA签署的协议，JAXA获得了约0.6克“贝努”样本。8月22日，JAXA在宇宙科学研究所举行了记者会，宣布正式接收这些样本，并表示将立即展开尘埃重量测量等工作。
值得一提的是，JAXA发射的探测器“隼鸟二号”曾于2020年从小行星“龙宫”带回了尘埃等样本。通过对“龙宫”和“贝努”的样本进行对比分析，科学家们有望获得更多关于地球生命起源、太阳系诞生以及小行星演化等方面的关键信息。
JAXA表示，未来将与曾参与“龙宫”样本分析的国内研究机构等合作，进一步开展对“贝努”样本的分析工作。相信这些来自宇宙深处的样本，将为人类揭开更多宇宙奥秘，为我们对地球生命起源和太阳系演化的认知带来新的突破。

News Content:
NASA has provided the Japan Aerospace Exploration Agency (JAXA) with a portion of the samples collected from theasteroid Bennu last year, sparking widespread interest in the scientific community. It is hoped that the analysis of these precious samples will yield new scientific discoveries in areas suchas the origin of life on Earth and the birth of the solar system.
Bennu is an asteroid whose orbit lies between Earth and Mars. NASA’s asteroid sample return spacecraft, OSIRIS-REx, arrived at Bennuin 2020 and successfully collected 121.6 grams of dust and other samples using its robotic arm. The sample capsule returned to Earth last September, bringing scientists a precious gift from deep space.
Under an agreementbetween NASA and JAXA, JAXA received approximately 0.6 grams of Bennu samples. On August 22, JAXA held a press conference at the Institute of Space and Astronautical Science, announcing the official receipt of these samples and stating that they will immediately begin work on measuring thedust weight.
It is worth noting that JAXA’s Hayabusa2 probe brought back dust and other samples from the asteroid Ryugu in 2020. By comparing the samples from Ryugu and Bennu, scientists hope to gain more key information about the origin of life on Earth, thebirth of the solar system, and the evolution of asteroids.
JAXA has stated that it will further collaborate with domestic research institutions that participated in the analysis of Ryugu samples to conduct further analysis of the Bennu samples. It is believed that these samples from deep space will unlock more cosmic mysteries for humanity, leadingto new breakthroughs in our understanding of the origin of life on Earth and the evolution of the solar system.
