NASA的贝努小行星样本含有碳和水

NASA从太空采集并带回地球的45亿年前的小行星贝努(Bennu)样本的初步研究显示,该样本含有高碳含量和水的证据,这可能表明,在这块岩石中可能发现了地球上生命的基本组成部分。

NASA首个小行星样本着陆,现已安全存放在洁净室

经过NASA OSIRIS-REx(起源,光谱解释,资源识别和安全-风化层探测器)团队多年的期待和努力工作,从小行星贝努收集的岩石和尘埃的胶囊终于到达了地球。它于周日上午8点52分(美国东部时间上午10:52)降落在盐湖城附近的国防部犹他州测试训练场的目标区域。

以下是9月24日小行星样本运送的工作方式

9月24日周日清晨,OSIRIS-REx航天器的样本舱将自2016年发射以来首次与地球大气层面对面接触。航天器上估计有8.8盎司(250克)的岩石物质,这些物质是2020年从贝努表面收集,这是NASA的第一个小行星样本,也是迄今为止在太空中收集的最大的小行星样本。 当OSIRIS-REx航天器接近地球时,它不会因为样本释放而减速。相反,当它到达地球表面以上63,000英里(或102,000公里)时——大约是地球到月球距离的三分之一——地面操作人员发出的一条信息将触发太空舱的释放,太空舱将被送入下方的大气层。释放太空舱20分钟后,航天器将启动其推进器,绕过地球,转向小行星阿波菲斯,在那里它将以一个新的名字——OSIRIS-APEX (OSIRIS-Apophis Explorer),继续研究我们的太阳系。 与此同...
