北京时间5月10日14时24分，在印度洋安达曼岛以西560公里处的天空中传来了低沉的爆响，一团巨大的火球划破天际，包裹着一块钛合金外壳的球状物 体，最终坠落在印尼西面的印度洋外海。所幸这次坠落没有造成任何人员和财产的损失，也没有出现科幻电影中钛球落地变形为外星机械的夸张场景。 一、这究竟是什么？ 地球大气层几乎每时每刻都有外太空物质进入，例如大量微小的陨石颗粒，它们大部分会在高速进入大气层时剧烈摩擦分解燃烧殆尽，流星现象就源于 此，而某些没有燃烧分解完毕的物质则会坠落到地表，形成陨石或太空垃圾残骸。然而这件坠落物并不普通。它原本来自地球，计划奔赴另一颗行星，却 在太空中漂泊了53年，最终回到地球。 它的真实身份是半个世纪之前的苏联金星探测器——金星9A，后又得名为宇宙482号（Kosmos 482）。听起来像是苏联上世纪航天计划中随处可见的普通 工程编号，但它的故事，堪称"冷战时代的太空漂流瓶"。 图源：莫斯科航天博物馆 二、金星9A的发射背景 故事开始于1972年春，当时正值苏美两国冷战高峰，苏联虽然在载人登月方向上落后，但他们已经在另一颗星球探测上取得了突破，他们的目标是比月球 更遥远，完全被硫酸云层所包 ...

"宇宙482"的运行轨迹一直受到各国天文学家和太空交通专家的关注。"宇宙482"宽约1米，重约495公 斤，单论体积和重量，它在近年重返地球的太空垃圾中并不算突出。但问题出在"宇宙482"的坚固设计 上。通常而言，当废弃卫星或其他太空垃圾重返地球时，它们会与地球上空的稠密大气层发生高速摩擦 而基本焚毁，最多也只有少量残骸落到地面。但"宇宙482"是为探索金星而专门研制的，金星的大气密 度是地球的90倍，为抵御降落时与金星大气摩擦产生的高温和压力，苏联工程师为它设计了一个坚固的 隔热罩，如今可能仍然完好无损，因此"宇宙482"大概率会以基本完好的状态撞上地球表面。美国"太 空"网站10日称，根据专家估算，如果"宇宙482"在再入地球大气层的过程中没有破裂，可能会以每小时 240公里的速度撞击地球，其威力相当于直径0.5米（落地后）的陨石落到地面。 【环球时报综合报道】据美联社10日报道，苏联时代发射的一颗废弃的金星探测器，在太空中漂泊53年 后，于当天重返地球。幸运的是，这颗失控的探测器最终落入印度洋，没有造成地面人员伤亡或财产损 失。 报道称，苏联于1972年3月发射了这颗金星探测器，代号"宇宙482"，它原 ...

在轨轮换期间，两个乘组进行了全面交接，包括飞行器飞行状态设置、在轨物资状态及管理使用情况、延续性工作进展情况等 方面内容。神二十乘组观摩协助神十九乘组开展下行物品整理、装包及转移等工作，并在神十九乘组撤离后完成了站内相关区域、 装置状态恢复及物资整理复位等工作。 舱门添置新防护 央视网消息：自4月25日进驻中国空间站以来，神舟二十号乘组三名航天员陈冬、陈中瑞、王杰迅速适应微重力环境，顺利开 启"太空出差之旅"。 "太空换班"再接力 乘组开展首次医疗救护在轨训练 乘组按计划开展了首次医疗救护在轨训练，通过训练感受天地差异，熟悉微重力环境下的救护操作方式、施力特性等。 开展多项医学检查 定期进行失重防护锻炼 乘组还开展了听力测试、超声检查、心电血压监测等多项医学检查，并定期进行失重防护锻炼。在轨半个月以来，神二十乘组 身心状态良好、工作进展顺利。 近期，神二十乘组完成了核心舱、节点舱、径向舱门空间碎片防护装置在轨安装工作，通过物理防护降低微小空间碎片撞击对 舱门造成的不利影响。此前，核心舱前向、后向舱门相关装置已完成安装。在神舟十九号撤离空间站的视频画面中，我们可以看到 舱门上醒目的红色"中国空间站"标识。 此外 ...

但美国《纽约时报》指出，由于"宇宙-482"是一个金星探测器，设计用于承受金星表面460度以上高温 和90倍地球气压的极端环境，该航天器有可能在坠落过程中保持"完好无损"。美联社称，根据联合国条 约，任何幸存的残骸都属于俄罗斯。 【文/观察者网 陈思佳】据俄罗斯塔斯社5月10日报道，俄罗斯国家航天集团证实，苏联于1972年发射 的金星探测器、被命名为"宇宙-482"（Kosmos-482）的航天器在流浪53年后重返地球，于莫斯科时间10 日9时24分（北京时间14时24分）进入大气层，最终坠落在中安达曼岛以西560公里的印度洋海域。 俄罗斯国家航天集团表示，坠落的航天器质量接近500千克，但不太可能构成威胁，"事实上，平均每天 有5个物体坠落到地球上，其中七分之一的质量超过500千克，我们可以在夜间观察到它们，就像流星一 样。但造成物质损失的情况非常少见，也没有引发过人员伤亡。" "宇宙-482"是苏联拉沃契金科研生产联合体研制的一对金星探测器之一，在设计、机载系统和科学设备 方面与"金星8号"探测器相同。1972年3月31日，"宇宙-482"从苏联拜科努尔航天发射场发射升空，但由 于运载火箭出现故障，该探测 ...
