历史一刻:日本太空车登陆小行星探测

分享

【新三才编译首发】日本航天局宣布,日本通过在小行星表面登陆「两个探测器」创造了历史。「它们处于良好状态并传输了照片和数据。」该航天局发推文说。「我们也证实他们正在表面上移动。」

这样的机动性是历史性的纪录。美国宇航局于2001年在一颗小行星上登陆了一艘太空船,但是日本的太空车可以在小行星表面四处移动并拍照。据日本航天局称,这使得它们成为「世界上第一个探索小行星表面移动的人造物体」。小行星吸引著感兴趣的科学家用其来研究宇宙的历史,并且它们具有丰富的商业潜力,至少新兴的小行星采矿业者希望如此。

日本航天局项目经理Yuichi Tsuda在9月22日的一份声明中表示,「我无法用言语表达我是多么高兴,因为我们能够在小行星的表面上实现移动探测。」「我很自豪Hayabusa2能够为这种技术的创造做出贡献,通过在小行星体表面运动来进行太空探索的新方法。」

日本航天局表示,太空车被设计成围绕小行星「跳跃」,因为在如此低重力的环境中,任何「正常轮子或爬行器推动的东西都会向上漂浮」。配备七个摄像头的太空车每次高空飞行15分钟。

预示著「第二太空时代」的高盛认为小行星可能具有巨大的经济潜力,从小行星开采铂金到开发太空新技术。「太空曾经是政府的唯一领域,但在过去的半个世纪里,这已经稳步发生变化。」该银行最近的一份报告称。「美国宇航局和私营企业正在推动已知和未知的边界,引领着22世纪的经济。」

这将提出有关太空战争和地球竞争的新的现实和法律问题。一方面,1957年的条约不允许主张太空主权。联邦官员、私人企业和其他外交官最终将需要同意根据新技术管理太空人类活动的手段。

「我们相信,例如,小行星上有很多矿物,特别是有价值的金属和稀土。」美国商务部长威尔伯·罗斯(Wilbur Ross)在8月份说道。「那么,你如何确定他们的头衔?你如何建立采矿权?是先到先得吗?是拥有最大太空船的人,还是第一个把武器放在那里的人?你如何确定谁真的会这样做?……但对我来说,更基本的问题是:如果不存在某种可执行性,法律并没有太大意义。这是一个巨大的开放性问题。」
