德国初创公司Isar运载火箭成功入轨 创欧洲本土私营航天首例German Startup Isar Aerospace Launches Rocket Into Orbit in Historic European First

Isar Aerospace研发的无人驾驶Spectrum运载火箭于格林尼治标准时间周六20时12分（挪威当地时间22时12分）在挪威北极圈安岛发射场点火升空。直播画面显示，该枚长达28米（约92英尺）的小型运载火箭升空后迅速加速，在起飞不到4分钟内便攀升至距离地表100公里（约62英里）的高度，顺利脱离稠密大气层并进入预定近地轨道。

The uncrewed Spectrum rocket, developed by Germany-based Isar Aerospace, blasted off from the Andøya spaceport in Arctic Norway at 10:12 p.m. local time (20:12 GMT) on Saturday. Broadcast commentators noted during the live transmission of the liftoff that the 28-meter-long (92 ft) vehicle accelerated rapidly after clearing the launchpad, crossing the 100-kilometer (62-mile) altitude threshold above Earth's surface in less than four minutes to reach target orbital parameters.

该运载工具主要面向中小规模载荷的运送需求，旨在将民用与军用卫星送入距离地表数百公里的近地轨道。在本次飞行过程中，Spectrum火箭顺利释放了机舱内搭载的5颗小型卫星，并完成了一项机载技术实验。Isar Aerospace在任务确认报告中表示，卫星完成轨道部署后，航天器分离程序全部顺利完成，实现了既定飞行与载荷入轨指标。

Engineered to carry small and medium-sized payloads, the launcher is designed to deliver both civilian and military satellites into low Earth orbit at altitudes of several hundred kilometers. During its orbital ascent, the rocket released five small satellites and conducted an in-flight technological experiment. Isar Aerospace confirmed following the deployment sequence that spacecraft separation was completed successfully, marking full execution of the vehicle's orbital delivery and flight qualification tasks.

总部位于巴伐利亚的Isar Aerospace历经数年技术攻关，完成了本次从首飞失利到载荷入轨的关键跨越。该公司于18个月前执行首次试飞，但火箭在起飞后30秒坠海爆炸；随后的第二次发射计划原定于1月进行，但在经历数次推迟后最终于周六付诸实施。本次任务既是Spectrum运载火箭的技术资格验证飞行，也是该型号首次承担载荷入轨任务。

Bavaria-based Isar Aerospace achieved its orbital delivery milestone following an extensive development effort that overcame an earlier test failure. The company conducted its initial Spectrum flight 18 months prior, during which the vehicle exploded and plunged into the sea 30 seconds after liftoff. While a second attempt was originally scheduled for January, it encountered several postponements before Saturday's launch, which served as both the rocket's official qualification mission and its first flight carrying operational payloads.

针对此次轨道发射成果，德国联邦研究、技术与航天部通过社交媒体平台公开发表声明，称德国已具备轨道航天运载能力，并赞扬该项目展现了国家的技术专长与创新实力。随着商业太空任务需求增长，英国与瑞典等欧洲国家亦对在欧洲大陆发展本土商业发射服务表达了浓厚兴趣。

Following the deployment, Germany's Ministry for Research, Technology and Space commended the launch in a statement on X, affirming that Germany possesses independent spaceflight capabilities and describing the flight as a demonstration of national technical expertise and innovative strength. The achievement aligns with expanding regional interest in commercial orbital operations, as European nations including Britain and Sweden pursue domestic launch infrastructure across the continent.

在切断与俄罗斯联盟号运载火箭的合作后，欧洲长期难以利用自身技术将卫星送入轨道，面临着自主发射能力不足的现实瓶颈。西欧此前曾在2023年1月尝试通过理查德·布兰森旗下的维珍轨道公司发射卫星，但因发生异常而未能入轨。受限于本土发射运力短缺，欧洲的大部分卫星运载需求只得转由埃隆·马斯克旗下在美国运营的SpaceX等机构承担。

Following the termination of cooperative ties involving Russia's Soyuz launch vehicles, European space programs have faced persistent constraints in placing satellites into orbit using regional technology. An earlier effort in January 2023 to launch a satellite from Western Europe via billionaire Richard Branson's Virgin Orbit failed to achieve orbital parameters after reporting an in-flight anomaly. Constrained by a lack of domestic launch capacity, European institutional and commercial operators have relied heavily on Elon Musk's US-based SpaceX to transport payloads into space.

美欧之间的年发射规模呈现出显著差距，去年全美发射了198枚运载火箭，而整个欧洲同期仅完成8次发射。除了总部位于法国、在南美洲法属圭亚那运营航天发射场的空中客车与赛峰合资企业ArianeGroup之外，欧洲正将希望寄托于处于早期研发阶段的新一代小型商业运载火箭，力求在未来以更低成本发射卫星。德国总理弗里德里希·默茨曾在3月同挪威首相一同视察Isar的发射现场，表达了在国际秩序发生变化的背景下对欧洲航天自主与减少对美依赖的支持。

The launch frequency gap between the two regions remains substantial, with the United States conducting 198 rocket launches last year compared to eight across Europe. Alongside ArianeGroup, the joint venture between Airbus and Safran operating from French Guiana in South America, European leaders are looking toward early-stage small commercial launch vehicles to reduce orbital transport costs. German Chancellor Friedrich Merz visited Isar Aerospace's Norwegian facilities alongside Norway's prime minister in March, expressing backing for European space autonomy amid shifting international dynamics under US President Donald Trump and reiterating concerns regarding reliance on American launch providers.

为推动运载火箭研发并扩建测试与发射基础设施，Isar Aerospace在8月与欧洲航天局签署合作协议，获得了总额达2.3亿美元（约合2亿欧元）的资金支持。这笔合同旨在启动欧洲发射器挑战赛，通过引入官方资助来促成欧洲发射服务商之间的市场化竞争，加快本土商业运载工具的技术成熟与发射频次提升。

To accelerate the development of new launch vehicles and extend its testing and operational facilities, Isar Aerospace secured a $230 million (€200 million) contract with the European Space Agency in August. The institutional funding agreement was structured to initiate the European Launcher Challenge, introducing targeted backing to stimulate commercial competition among regional launch operators seeking independent access to space.

在制造与发射网络拓展方面，Isar Aerospace设定的远期目标是实现年产约40枚运载火箭的产能规模。尽管Spectrum火箭目前尚未正式进入大规模量产阶段，但公司已经锁定了排期至2028年的发射商业订单。与此同时，该初创企业正推进海外发射场建设，规划在加拿大建立第二个发射基地，以扩大未来的商业发射服务覆盖范围。

On the operational front, Isar Aerospace has outlined production targets to manufacture approximately 40 launch vehicles annually. Although the Spectrum rocket is not yet prepared for full-scale mass assembly, the startup has already accumulated customer flight orders extending through 2028. To support future mission volume and diversify its launch sites beyond Arctic Norway, the company is also developing a second spaceport installation located in Canada.
