中科宇航力箭二号遥二运载火箭顺利出厂，拟于今年 10 月完成发射_我的网站

一 |      8 月 26 日消息，中科宇航今日宣布，8 月 25 日，中科宇航力箭二号遥二运载火箭已按流程完成出厂前各项工作，产品功能、性能指标均满足飞行任务要求，顺利通过出厂评审，整装待发奔赴发射场，拟于今年 10 月完成发射。据介绍，力箭二号运载火箭是我国首款“通用助推器核心”构型的运载火箭，500 公里太阳同步轨道运载能力 8 吨，200 公里近地轨道运载能力 12 吨，具有运载能力大、固有可靠性高、可制造性强、操作简洁便利、拓展空间强、可重复使用等优势。    (ECNS) -- An "Ice Silk Road" is emerging in the Arctic, offering China and Europe a shorter maritime link and, more importantly, a new option for navigating an increasingly uncertain global trading environment.    Chinese container shipping company Sea Legend Line has announced plans to launch the first regular container service across the Arctic. The route is set to begin its maiden voyage on Saturday and will operate weekly, with eight voyages scheduled.        The route underwent a trial voyage last autumn. In September 2025, the container ship "Istanbul Bridge" departed from Ningbo-Zhoushan Port and arrived at the Port of Felixstowe in the United Kingdom 20 days later.    The new China-Europe Arctic Express will pass through the Bering Strait and sail westward along the Northeast Passage, reaching Felixstowe in the United Kingdom in just 18 to 20 days before connecting with ports in Germany, the Netherlands and Poland.    By comparison, shipments from China's Ningbo-Zhoushan Port to Europe via the Suez Canal typically take at least 40 days. Rerouting around the Cape of Good Hope due to congestion or geopolitical disruptions can extend transit times to more than 50 days.    The Arctic route could offer significant advantages in both speed and cost. Faster deliveries would allow Chinese manufacturers to reduce inventory levels and accelerate cash flow. Reports suggest that companies using the route could cut inventories by as much as 40%.    The naturally low temperatures along the route could also make it suitable for transporting high-value, temperature-sensitive cargo, including precision instruments and new-energy batteries. Carbon emissions are expected to be nearly half those of traditional routes, according to reports.    The route also bypasses major maritime chokepoints and areas affected by geopolitical tensions, including the Strait of Malacca, the Red Sea and the Gulf of Aden. This could provide companies with an additional option for improving the stability and resilience of their supply chains.    However, the route also faces significant challenges. Sea ice limits the navigable season to roughly late July through October, while port services, supplies and emergency-response infrastructure along the route remain limited. It therefore cannot yet operate year-round and is unlikely to replace the Suez Canal route in the short term.    Nevertheless, the Arctic route could strengthen the resilience and diversification of China-Europe trade. Together with land-based routes such as the China-Europe Railway Express, it could give China more options for transporting goods to European markets and reduce reliance on traditional southern maritime routes.    Italian financial newspaper Il Sole 24 Ore described the route, dubbed the "Ice Silk Road," as a symbolic revival of the ancient trade links between East and West.    As new shipping routes emerge across the Arctic, the geography of global trade may gradually be reshaped, giving international supply chains more options in an increasingly uncertain geopolitical environment.    (By Gong Weiwei)                                。作为我国大规模星座组网和低成本货物运输的主力运载火箭，将支撑低轨星座规模化组网、低成本空间站货物运输及各类科学实验卫星发射。注意到，力箭二号运载火箭已完成首飞验证。今年 3 月 30 日，力箭二号遥一运载火箭成功将轻舟初样试飞船和 2 颗卫星精准送入预定轨道，单次任务输送 4.2 吨载荷入轨，首飞圆满成功、指标表现优异。官方表示，本次力箭二号遥二运载火箭总装测试工作高效有序推进。团队持续优化生产、总装、测试全流程工艺，迭代提升产品研制效率与交付质量，火箭总装测试周期较首飞实现稳步缩短，向标准化、批量化研制发射目标稳步迈进。
