A | Female candidates sitting the NEET medical entrance examination in India's southern state of Kerala were asked to remove their bras before taking the exam, several Indian media outlets, including NDTV, reported.,The shocking incident came to light after the father of one of the girls complained to the police.,According to reports, female security personnel posted at a examination center in the Kollam district told women aspirants to remove their bras because the metal hooks were making metal detectors beep during the security check.,The students eventually removed their bras as they were informed that if they didn't comply, they would not be allowed to sit the exam.,"Is your future or innerwear big for you? Just remove it and don't waste our time," the security staff reportedly said, according to a complaint launched by one father.,While the Marthoma Institute of Information Technology where the alleged incident happened denied any involvement, Kollam's Police head KB Ravi acknowledged that a complaint from a girl's father had been received.,"After a security check, my daughter was told that the hook of the innerwear was detected by the metal detector, so she was asked to remove it. Almost 90% of female students had to remove their inners and keep them in a storeroom. The candidates were mentally disturbed while writing the exam," the girl's father added.,Several girls wept as they "cut their hooks" to write the exam.,"The mental state of these children was disturbed, and they could not attend the exam comfortably," the letter of the girl's father to the police concluded.。

当天下午2:34,一个从天而降的不明物体,突然砸中了他们位于那不勒斯市的房子。
C | 该物体击穿屋顶,穿过了两层楼,砸入了地板里。

D | “当时发出了十分巨大的声音,
(这个物体)差点就砸到我儿子了。”博特罗在接受当地媒体WINK News的采访时说道。
E | 然而,火箭在起飞不久后,助推器失灵,没能成功进入轨道,两位宇航员只能返回地面,没有按计划到达国际空间站。

F |
黑格此次前往国际空间站的任务之一是帮助空间站升级电力系统。
G | 他会到空间站
外进行太空行走,帮助换掉原来的镍氢电池,并安装新的锂离子电池。可惜黑格并没有按时到达空间站。

但问题是,第一批锂离子电池已经由日本的HTV货运飞船运送至了国际空间站。
I | 原本的计划是,被这一批锂离子电池替换的旧镍氢电池,用同一艘HTV货运飞船带走。但由于黑格没能登上空间站,NASA只好暂时取消此次换电池的太空行走任务,将锂离子电池留在空间站,等待下一个能执行该任务的宇航员到来。
这艘HTV货运飞船也只能直接离开,并未带上镍氢电池。由于每艘飞船的载货量都是固定的,所以HTV货运飞船没办法一次性带走两倍数量的旧电池。
J | 于是,随后每一次HTV货运飞船运来新一批的锂离子电池,都会带走上一批替换下来的旧镍氢电池,直到2020年最后一艘HTV货运飞船离开国际空间站。但这时,空间站上还剩下最后一批镍氢电池没有带走。这个装有九块旧镍氢电池的货物托盘,编号为EP9,总重量相当于一辆大型SUV。

空间站丢弃EP9

而最后的结果大家已经知道了,EP9其中一块碎片并没有在重返大气层的过程中完全被烧掉,也并没有直接落入墨西哥湾,而是落向了旁边的佛罗里达,最终击中了亚历杭德罗·博特罗的房子。为了确认击中博特罗房子的物体就是EP9的碎片,NASA与博特罗取得了联系,将该物体送到了NASA位于佛罗里达州的肯尼迪航天中心。通过分析该物体的尺寸、特征和材料,并将其与EP9上的硬件相对比,NASA最终确定,该物体是EP9上的一根支柱,用于将电池固定在货物托盘上,由铬镍铁合金制成,重 0.7kg,10cm,直径 4cm。该物体与完好支柱对比

N | 国际空间站就曾多次为避开太空垃圾,而调整轨道。
至于太空垃圾对地面的影响。ESA表示,大约每一周就会有一个较大的空间物体通过大气层冲入地球,不过大部分碎片在到达地面之前就已经完全燃烧了。
o | 大多数航天器、运载火箭和运行硬件的设计都是为了尽量让其在大气层中完全燃烧,从而降低相关风险。
但此次EP9事件告诉我们,太空垃圾也可能会威胁地面。事实上,这已经不是第一次太空垃圾砸向地面,并威胁人身安全的事件了。据《纽约时报》(The New York Times)报道,1969年,苏联航天器的碎片击中了西伯利亚海岸附近的一艘日本小船,造成 5 人受伤。据福克斯新闻(Fox News)、ABC新闻(ABC News)等多家媒体报道,1997年,美国俄克拉荷马州的一位居民也曾被火箭的碎片击中过肩膀。不过,大家也不用过于恐慌,毕竟被太空垃圾击中的概率非常非常小,而且世界各国也在积极尝试太空垃圾的清理办法,如英国2018年就开始部署“清除碎片”系统,相信未来我们可以还太空一个干净的环境。
