China's Space Program News Thread


Quickie

Major
The last column is the payload.

However, this is the currently planned moon rocket, there is no other. There was a CZ-5 based manned moon rocket in the thought called CZ-5DY (Deng Yue, moon landing) in 2013, but that never left paper. Besides, this new CBC rocket is CZ-5 derivative in Chinese mind. Actually, there was only CZ-5 from the beginning,CZ-7 used to be the medium sized CZ-5 in the initial plan, then got its own branch, later on CZ-720 (HO) became CZ-8. The Chinese naming principle is that anything that is based on 3.5m core and YF-100x are CZ-7 (then CZ-8). Anything with 5m core is CZ-5. Anything with 10m core is CZ-9.

The only other moon rocket is CZ-9, but that is a beast of over 50 tonnes LTO, doubling this CBC of >25 tonnes LTO.

The program is not only real, but is being produced, see #4888 which showed the first stage and #4889 the second stage. This design has passed technical review a month ago. See here

I can't access the link.

By real, I meant going beyond experimental. From the brief info that you've given, there's no mention of it being experimental and, imo, barring any obstacle, it will turn out to be a full-fledged launcher development just as the CZ-5 was.

新一代载人火箭预研项目顺利验收
发布日期:2019年10月12日 来源 : 航天科技集团 字体: 【大】【中】【小】
  10月9日,中国航天科技集团有限公司一院“5米直径模块新一代载人火箭总体技术与工程应用”项目,顺利通过中国载人航天工程办公室组织的验收评审。评审专家一致认为,该预先研究项目的成果可用于中国新一代载人运载火箭工程研制。


  根据我国载人航天工程的长远任务规划和新一代运载火箭体系的发展构想,一院在工程总体支持和牵引下,于2017年启动我国新一代载人运载火箭的预先研究,历经多轮论证和研制,如今迈出关键一步。


  作为支撑航天强国建设的重要手段,该项目勾勒出新一代载人火箭总体雏形:箭长约87米,起飞重量约2200吨,起飞推力接近2700吨,LTO(奔月轨道)运载能力不低于25吨。后续,火箭的具体研制计划还将在工程总体和航天科技集团的安排下,不断更新、完善、细化。


  火箭将采用新型逃逸系统设计技术,轻质高效结构设计和先进制造技术,轻质高可靠推力矢量控制技术,火箭纵向耦合振动抑制新技术,先进测试发射技术,火箭动力系统冗余和飞行控制重构技术,冷氦增压技术,低冲击高可靠船箭分离技术等,其中大直径大温差低温共底贮箱设计和制造技术、百吨级推力贮箱箱底传力结构设计和制造、大推力火箭发动机电静压推力矢量控制等技术为国际首创。


  该火箭将充分继承长征五号、长征七号等新一代运载火箭成熟的发动机技术和高可靠飞行控制技术;同时简化逃逸模式,提高了航天员的安全性。采用多台发动机并联,千吨级捆绑载荷传递和箭体结构设计一体化等方法,并采用大量新材料、新工艺,使火箭运载效率有较大提高。
I am not sure if I understand the rest of your comment though. So I will just repeat what I believe. This CBC manned rocket is not experimental, it will turn out to be a full launcher with some tuning. The thing is that there was NEVER an experimental launcher in China's history, as far as I am aware. It seems to me that China does a long and through pre-study of various configurations on paper and in calculation, together with component research, then decide on ONLY one design to be produced. It is the same as the 4th gen fighter jet, J-20 is the only one made in full development, other competing options never left drawing board. This approach is very different from the US, of course.

As a side note, there is a report about 8th academy in Shanghai just made a 3.8m tank if I remember correctly. People are speculating that it is 8th academy's competing design for the new manned launcher. It is speculated to be 5 CBC 1st stage. If it is true that it is a competing design, it will be the first time in Chinese rocketry history to have physical prototype competition. BUT I highly doubt this is the case because unlike this 5m CBC being shown in CASC's presentation and official report, this supposed competing design has never went public and remained as speculation by netizens.

More than a decade ago, Dr APJ Abdul Kalam, a scientist also known as the Missile Man of India who was also the 11th President of India,

. His broad argument was that the Earth, Moon and Mars should be considered as single economic entity. At the 97th Indian Science Congress, which was hosted by the Indian Space Research Organisation (ISRO) in January, 2010. he said, “Scientists should start considering Earth, Moon and Mars as an economic complex for future habitat expansion of human beings.” He made similar arguments at a seminar held at the Institute for Defence Studies and Analyses (IDSA) in New Delhi in November 2007.

China, it appears, has taken heed of Kalam’s concept. It was recently reported that

. Bao Weimin, director of the Science and Technology Commission of the China Aerospace Science and Technology Corporation (CASC), discussed a very ambitious proposal to establish an Earth-Moon space economic zone by 2050. Some estimates indicate that such a zone could create an economy worth $10 trillion a year.

The initial work investigating the feasibility of establishing such a zone is expected to be completed by 2030. This is expected to involve basic research and development of key technologies. China expects to establish a space transportation system enabling this economy by 2040 and then, within a decade, proposes to establish the Earth-Moon space economic zone. From the Chinese side, this idea of economic zone was first announced during 2016, by Zhang Yulin, then deputy commander-in-chief of China’s human spaceflight program. Now, after three years, China has come out with a timeline for implementation of this project and it appears that those experts believe that it could become a reality.

China conducted two launches within three hours on Wednesday, placing a commercial Earth observation satellite and five military surveillance satellites into orbit.

A four-stage Kuaizhou 1A booster lifted off with the Jilin 1 Gaofen 02A satellite at 11:40 a.m. Beijing time from the Jiuquan Satellite Launch Center in northwestern China.

The commercial imaging satellite, owned by Chang Guang Satellite Technology Co. Ltd., is designed to return high-definition video and images for civilian and military users.

The spacecraft joins 13 other Jilin-1 satellites launched by Chang Guang, which is a commercial spin-off of the Chinese Academy of Science’s Changchun Institute of Optics, Fine Mechanics and Physics.

Expace, a commercial subsidiary of the state-owned China Aerospace Science and Industry Corp., manages Kuaizhou 1A launches. The booster is believed to be based on a Chinese ballistic missile.

Three hours after Kuaizhou 1 lifted off, a liquid-fuel Long March 6 booster launched from the Taiyuan Satellite Launch Center with five Ningxia 1 military remote sensing satellites.

Photos taken on Nov. 14, 2019 shows the trial ground of an experiment for landing on Mars in Huailai County, north China's Hebei Province.
China on Thursday unveiled an experiment simulating the process of a probe hovering, avoiding obstacles and descending to land on Mars. China plans to launch the Mars probe in 2020, aiming to complete orbiting, landing and roving in one mission, an unprecedented achievement, according to the China National Space Administration. How to safely land on Mars is one of the biggest challenges facing the mission. The experiment simulated the gravity of Mars, about one-third of the gravity on Earth, to test the design of the lander. (Xinhua/Jin Liwang)
