今天（12日）早上，在海南文昌航天发射场，天舟九号货运飞船和长征七号遥十运载火箭组合体开始进行垂直转运。 今天的垂直转运工作从早上8时正式开始，搭载着天舟九号货运飞船的长征七号遥十运载火箭，在活动发射平台的托举下，驶出了总装测 试厂房，沿着专用的无缝钢轨，向着火箭发射塔架的方向平稳运行。预计整个转运的用时将在两个半小时到三个小时之间。 垂直转运标志着飞船和火箭前期在技术区的总装和测试工作已经完成，正式进入到火箭发射准备阶段。 这一次天舟九号货运飞船计划将要上行大约6吨重的补给物资，主要用来保障神舟二十号和神舟二十一号两批航天员乘组在轨生活、工作 所必备的物品。 特别值得关注的是，这次将上行2套全新的飞天舱外服，这是我国自主研制的舱外航天服，它的设计寿命由原来的3年15次大幅提升为4年 20次；另外，中国空间站的太空健身房设备将再次升级，这次将上行1套全新的核心肌肉锻炼装置，有助于航天员在太空微重力环境下避免肌 肉萎缩的问题；此外，还将上行2套前沿的空间科学实验装置。 这次天舟九号任务的发射流程跟以往基本保持一致，没有做太大的调整，主要继承往次发射的成功经验，确保这一次任务的可靠性。按照 计划，接下来任务各个系 ...

Core Viewpoint - The Tianzhou-9 cargo spacecraft is set to launch soon, carrying approximately 6.5 tons of supplies to support the Shenzhou-20 and Shenzhou-21 astronaut missions, including new space suits and upgraded equipment for the space station [1][7]. Group 1: Mission Preparation - The Tianzhou-9 spacecraft and Long March 7 rocket have been transported to the launch site, with all systems in good condition and ready for pre-launch checks and tests [1][4]. - The Long March 7 rocket, standing at 53 meters tall, underwent various assembly and testing processes, including vertical assembly and system performance tests [4][7]. - The rocket's design utilizes advanced 3D digital technology, improving efficiency and reducing the risk of assembly issues compared to traditional 2D designs [8]. Group 2: Cargo and Equipment - The Tianzhou-9 mission will deliver essential supplies for astronauts, including two new sets of domestically developed space suits, enhancing their performance from 3 years and 15 missions to 4 years and 20 missions [7]. - New equipment for the space station includes a core muscle exercise device and advanced scientific experiment apparatus [7]. Group 3: Rocket Specifications and Capabilities - The Long March 7 rocket has a near-Earth orbit payload capacity of 14 tons, suitable for transporting cargo to the space station [7]. - The rocket employs environmentally friendly liquid oxygen and kerosene as propellants, utilizing YF-100 and YF-115 engines [7]. - The launch will mark the 10th flight of the Long March 7 rocket and its 8th mission for cargo transport to the Chinese space station [7]. Group 4: Precision and Navigation - The Long March 7 rocket can continuously optimize its flight path during ascent, enhancing the accuracy of orbital insertion [9]. - The insertion accuracy is impressive, with a deviation control of less than 4 seconds, which is crucial for the docking requirements of the cargo spacecraft [9].
