[China's new generation of manned launch vehicles have been confirmed to have been approved and are expected to fly for the first time around 2027] The Blue Book of China's Space Science and Technology Activities (2022) mentions: "The research and development of the new generation of manned launch vehicles and heavy launch vehicles have been carried out in an orderly manner to support the needs of manned landing on the moon, deep space exploration and other missions. The new generation of manned launch vehicles is the largest launch vehicle in China, with a take-off thrust of 2600 tons and a ground-moon transfer orbit carrying capacity of 27 tons. It has successfully carried out the joint static and dynamic tests of multiple engines in parallel, the long range test run of the second stage engine, and the long range multiple ignition tests of the third stage engine. The heavy launch vehicle has a 10-meter stage The structure of the large-diameter rocket storage tank has been successfully developed, and the key design, key technology, key equipment and key products have been independently controlled and upgraded, and the key technology research has been successfully completed.

Considering the new crewed rocket is named CZ-10 very recently, it seems to me that China will only give an official designation when the mission of that rocket is approved.

CZ-9 will have a reusable 1st stage. It will be heavier than 4000 tons with a thrust of more than 6000 tons, capable of delivering 150 tons to LEO, more powerful than Saturn-V.
The new, current plan for the rocket will be a three-stage, 108-meter-high, 10-meter-diameter and 4,180 metric ton rocket capable of delivering 150 tons to low Earth orbit (LEO), 50 tons to lunar transfer orbit (LTO), or 35 tons to Mars transfer orbit. The rocket is scheduled to be ready for test flight around 2030.

Gravity-1 all-solid launch vehicle developed by the private company OrienSpace will make its maiden flight in 2023. In 2025, Gravity-2 (re-usable liquid core + solid boosters) is scheduled to make first flight. In 2030, Gravity-3 (fully-reusable/recoverable) will make its maiden flight. Some 20 ground tests of various systems have been completed, including core stage engine for Gravity 1 and attitude control engines.

【东方空间引力1号中型全固体火箭今年底将首飞】东方空间公司规划将“引力”系列大中型运载火箭打造为全球顶尖运载火箭系列,按照“固液并存、循序渐进、有效迭代、系统创新”发展思路,实施“三步走”发展战略:
1)第一步:2023年,“固体芯级+固体捆绑”的引力-1号火箭实现首飞,成为我国商业航天第一款中型运载火箭。该箭运载能力达6.5吨,将把国内现有最大固体火箭能力提升3倍,国际领先;攻克全固体中型运载火箭集束捆绑、海上发射等核心技术,并将发射成本降低至我国商业航天业内最优;形成我国中大型航天载荷快速响应发射能力,满足低轨星座及中大型卫星快速发射服务需求。
2)第二步:2025年,“可回收液体芯级+可配置固体助推”的引力-2号火箭实现首飞,攻克液体火箭可回收技术;火箭运载能力在引力-1号基础上翻倍,进一步提升性价比;具备低轨大型卫星星座组网和高轨发射能力,达到国际先进水平。
3)第三步:2027年,“全回收通用助推及芯级”的引力-3号火箭实现首飞,成为我国商业航天一款大型运载火箭,攻克火箭全回收技术;运载能力在引力-2号基础上再翻一倍,进一步降低发射成本,让空间触手可及;具备巨型星座及空间站发射服务能力,奠定航班化飞行基础,达到国际一流水平。

目前,引力-1号芯一级发动机、助推级发动机热试车及自研700N、50N姿态控制发动机热试车等近20项地面试验圆满成功,产品状态确定,即将从初样转入试样研制阶段。
作为引力-2号可回收液体芯级主动力的原力-85液氧煤油火箭发动机,现已完成所有方案设计,全部产品投产。

东方空间在去年发布了引力-1号发射服务计划,提供规模化、便捷化的太空物流服务,签署了多发火箭发射服务合同(23年4季度首飞轨道500km×55ºLEO,24年1季度二飞轨道500kmSSO),理论上,每发引力-1号可搭载18~24颗200kg卫星,10次发射便可完成200颗卫星星座的组网,这将助力各类卫星及组网星座高效发射;启动了航天电子产品业务,完成了组网数据链关键技术突破,以及仿真综合处理单元、箭载安控组合设计交付。

东方空间在山东、北京、陕西、海南四地构建研发-试验-生产-发射四大能力,进一步提升了研发保障能力,电子信息试验中心、电子信息设备装调中心、半实物仿真中心、末修姿控动力液流试验中心等基础设施均投入使用,并取得开展发射业务所需的各项资质。

东方空间在2022年完成了A轮4亿元融资,首次亮相了珠海航展、中国航天大会等展会,并收获了诸多认可与荣誉:山东省创业大赛创新创业之星、中国先进制造领域最佳新经济企业TOP10、2022中国商业航天30强、2022中国最具投资价值企业、中国硬科技创新企业TOP20、金砖国家100强企业家奖、商业航天青年领袖奖等。

东方空间搭建了业内综合实力领先的技术研发团队,总体、结构、飞控、航电、软件、动力、发射支持等相关负责人,都曾任多个型号主任/副主任设计师,均在重点型号负责过核心研发工作,团队副高及以上职称专家达30余人,规模达150余人,其中70%为研发人员。

东方空间表示,在2023年将全力以赴确保引力-1号火箭首飞成功,原力-85火箭发动机研制成功,降低商业航天发射成本,提升发射服务能力,助力中国商业航天的繁荣与强大,为航天强国的奋斗目标贡献新价值,实现“从东方走向空间,为东方建设空间”理想。

A detailed model of the Xuntian space telescope, which is scheduled to launch later this year. The overall diameter of the telescope is 4.2m, and the mirror diameter is 2m. The telescope can dock with the Chinese space station for servicing. I spot five gyroscopes and a lot of attitude control engines.
