二 | Sidharth Malhotra made his debut more than a decade ago with a role that instantly made his everyone's favourite. Ever since, the actor has carved a distinct space for himself in Bollywood and has displayed his talent through his diverse filmography. From romantic dramas and to high-stakes action and biographical roles, Sidharth has shown a steady growth over the years and delivered performances that made him a bankable actor. Here are some of his memorable films that shows his range as an actor. In This Article Student of the YearHasee Toh PhaseeEk VillainKapoor & SonsBaar Baar DekhoShershaahStudent of the Year Student of the Year marked Sidharth Malhotra's charming debut. He played Abhimanyu Singh, an ambitious student who joins the elite St. Teresa’s College and is determined to win the coveted Student of the Year trophy. He meets Rohan Nanda; his foe turned friend and his girlfriend Shanaya (Alia Bhatt). As the competition intensifies, friendships and relationships are tested. The film explores themes of young love, ambition, loyalty, and personal growth. Directed by Karan Johar, the film also stars Rishi Kapoor, Ronit Roy, Sahil Anand, Manjot Singh, Ram Kapoor, Farida Jalal, Manasi Rachh, Sana Saeed, and Kayoze Irani among others. Hasee Toh Phasee Hasee Toh Phasee is a rom-com featuring Sidharth Malhotra as Nikhil, a financially struggling young man who is trying to prove himself to his girlfriend Karishma’s (Adah Sharma) family. His life takes an unexpected turn when he meets Meeta (Parineeti Chopra), Karishma's eccentric and brilliant sister who has been estranged from the family for years. As Nikhil reluctantly agrees to keep an eye on Meeta, they form an unlikely bond that slowly turns into love. They reveal their vulnerabilities, ambitions and emotions to each other. Finally, on his wedding day, Nikhil has to decide whether he will go forward with marrying Karishma or confess his love to Meeta. Ek Villain Ek Villain saw Sidharth Malhotra play Guru, reformed criminal who tries to rebuild his life after meeting Aisha, an optimistic woman who is battling a terminal illness. Their relationship brings out the gentler side of him and they eventually get married. Guru tries to leave the world of crime behind and earn money the honest way to afford Aisha's treatment. One day, she is elated to discover that she is pregnant with Guru's child. But before Aisha can share the good news with him, she is murdered by a serial killer Rakesh (Riteish Deshmukh). The loss pushes Guru back toward the darkness he tried to escape, setting him on a path of revenge. Kapoor & Sons In Kapoor & Sons, Sidharth Malhotra stars as Arjun Kapoor, a struggling writer who also has to navigate a fractured relationship with his family. Along with his estranged brother Rahul (Fawad Khan), Arjun returns to his childhood home in Coonoor after their grandfather suffers a heart attack. Their parents seem to favour Rahul because of his success, creating an even deeper rift between the brothers. Beneath the surface, the family is grappling with multiple unresolved tensions, including financial strain and Harsh's past extramarital affair. As the family tries to come together for their grandfather’s wish of a perfect family photograph, Arjun is forced to confront jealousy, childhood wounds and the painful truths that have shaped him. He also finds an unexpected connection with Tia (Alia Bhatt), which helps him rediscover warmth and hope. Sidharth brings a certain vulnerability to Arjun, capturing the insecurity and longing that sit beneath his composed exterior. Baar Baar Dekho Baar Baar Dekho is a romantic science-fiction film dealing with time travel. Sidharth plays Jai Varma, a brilliant mathematician who prioritises work over everything. His long-time relationship with Diya (Katrina Kaif) begins to fall apart when he struggles to give time to her. However, after a major argument, Jai mysteriously starts leaping forward in time, witnessing the future consequences of every choice he makes. These unexpected time-jumps force him to confront versions of his life where success has cost him the people he loves most. In one of the leaps, he finds out that he has become successful in his career but is about to get a divorce with Diya. In another leap, he sees that Diya has remarried another man. He begins to understand the weight of emotional neglect and starts valuing Diya more. Finally, Jai returns to his current timeline and vows to resolve his problems with Diya. Shershaah Shershaah is considered to be one of Sidharth's best performances. It is a biographical war drama based on Indian Army Captain Vikram Batra, who sacrificed his life during Operation Vijay of the Kargil War. The film follows Captain Batra’s journey from his days as a spirited young man to his rise as a fearless officer in the Indian Army. It also shows his deep bond with Dimple Cheema (Kiara Advani). We see Batra’s leadership during key missions of the Kargil War, including the capture of Point 4875, where he ultimately laid down his life. Sidharth received appreciation both from fans and critics for his performance in Shershaah. This also remains a special film in Sidharth's life as his love story with Kiara bloomed during this time and they eventually got married.

三 | 梅利乌斯研究公司航空航天、国防和太空研究领域主管斯科特·米库斯在通话中提出了“从特定角度看,假如这种航天器开发出用于干扰敌方卫星,其潜在市场究竟有多大”的问题,对此沃登并没有正面回答,但她表示,关于如何运用这项技术来实现任务目标,将由美国政府决定,公司的目标只是为客户提供“各种技术部署上的选择”,尽管没有正面回答,但也没有明确否认。 如前文所述,MRV上所配备的两个机械臂主要用于将扩展舱安放到目标卫星上(以及执行其他任务),而这两个机械臂也正是被称为“地球同步卫星机器人服务”(Robotic Servicing of Geosynchronous Satellites,RSGS)系统的一部分。该系统来源于美国国防高级研究计划局(DARPA)所主导、并与美国海军研究实验室(Naval Research Laboratory,NRL)合作开展的一项计划,是美国政府“数十年来在相关领域的研发成果”。 DARPA用于测试的RSGS载荷部分,可以看到两具机械臂 “战区”网站表示,航天器上的机械臂天然具有“双重用途”的特性,完全可以用来“破坏敌方卫星上的关键系统”,比如光学设备或者太阳能电池板,亦或者直接将其从轨道上“拽掉”,如果目标未能重新控制变轨修正,就将持续降低轨道高度直至再入大气层烧毁,此前美国军方也多次声称,带有机械臂的敌方航天器是美国太空资产的众多“潜在威胁”之一。在今年2月份举行的空军和太空部队协会(AFA)年度战争研讨会上的演讲中,美国太空部队指挥官、太空作战部长钱斯·萨尔茨曼上将声称,美国正在回应一种“战争领域”的情况,对手“已经在太空中部署了拦截器”,因此必须确保能在威慑能力方面与之抗衡,针对萨尔茨曼所称的“太空拦截器”,当时一位太空部队发言人解释称,“拦截器”指的是一些被广泛认为武器的系统,比如地面上的反卫星导弹,或者像中国的SJ-21——因为其有着一个“机械臂抓取装置”。 be like... 报道表示,除此之外“监视卫星”这种具备双重用途的航天器,也是多年以来的热门话题,比如俄罗斯在该领域的成果就相当引人关注。这种“致命”卫星还具备高精度在轨机动能力,能够使用包括电子战干扰装置、定向能武器、化学能武器或者小型弹丸摧毁或破坏太空目标,甚至其本身也可以通过直接撞击目标来进行动能杀伤。而即便仅仅是进行观察,也有助于“了解其功能并监测活动情况”,比如长期以来美国、俄罗斯和其他国家的卫星都在执行类似的任务,乃至于一些商业遥感图像公司也开始提供“基于太空的态势感知服务”。

四 | 总之,从之前的一些研究来看,美国军方显然对MRV这种航天器的核心功能有着强烈兴趣,比如在轨加注能为一些卫星提供重要的机动能力,目前航天器应对在轨威胁的主要方式就是应急变轨,但通常这需要耗费大量燃料从而缩短使用寿命。而美国太空部队还设立了一个专门负责执行“轨道作战”的任务部门,其中就包括了防御性和进攻性要素。美国太空部队作战部队司令部指挥官格雷戈里·加尼翁中将在同一场研讨会上表示,不能仅仅依靠防御手段来保护和维护卫星,作为联合部队的一部分必须具备进攻能力,而“中国不断扩大的太空能力”是支持这一观点的核心要素。 报道认为,保护美国在轨卫星的防御措施数量和规模需求将会显著增加,而正炙手可热的“金穹”国家导弹防御系统则更是进一步推动了这一趋势,该系统的核心内容正是部署基于太空的反导拦截装置,它们依托在轨道上广泛分布的一系列传感器和通信卫星运作。

五 | 美国国会预算办公室在5月发布的一份报告中估算,实现该计划所需的在轨拦截器数量将达到7800个,美国军方所关注的诺格MRV在轨加注和维护能力,对保障“金穹”系统以及其他关键太空传感器和卫星的运作可称得上至关重要。 本文系观察者网独家稿件,未经授权,不得转载。
