China's Space Program News Thread

[by78]

China has just released a new white paper on its space program. It summaries the past achievements and announces future endeavors. In the next five years, new rockets and satellites will be introduced and launched. China will continue lunar explorations, focusing on the lunar polar region. It will launch the Chang'e-6 and -7 probes, performing landing and sampling-return in the lunar polar region. China will also continue preparations for the Chang'e-8 mission and jointly carry out the construction of a lunar research station with international partners and organizations. China will continue to implement planetary exploration projects, launch asteroid probes, complete asteroid sample-return, and prepare for a Mars sampling-return mission. Remote surveys of Jupiter, the astroid belt, and further probes into outer reaches of the solar system will also be carried out. Also of note, an astroid monitoring and warning system will be implemented. There is a boatload of other projects listed and a lot to unpack.

The full Chinese text of the white paper is

Never is too strong. objects on geosynchronized orbits are stiill susceptible to drag from earth‘s extended atmosphere, so their orbits will decay But it will take 10s of millions of years for satellite sized object to decay from geosynchronized orbits.

What are "geosynchronized orbits"?

From my understanding, in GEO atmosphere is negligible.

In LEO at a 300 km the pressure is calculated ~1E-12 torr, which is better than any artificial vacuum at sea level. Empirically this is true as well. GEO is 30000 km.

I believe orbital mechanics beyond GEO are determined more by perturbative gravitational forces from other solar system objects, radiation pressure, solar wind pressure, etc. than anything to do with the atmosphere.

You needn’t argue with @Richard Santos. His degrees are in engineering physics and astronautics, among very many other subjects. He knows everything there is to know. He is the Grand amd Exalted King of Knowledge (太上懂王) of the Sinodefence Forum. Your understanding, although correct, means nothing.

今天上午国务院新闻办正式发布《2021中国的航天》白皮书。这是继2000、2006、2011和2016航天白皮书后发布的第五部航天白皮书。

白皮书全文约12500字，除前言、结束语外共包括六个部分，分别是开启全面建设航天强国新征程，发展空间技术与系统，培育壮大空间应用产业，开展空间科学探索与研究，推进航天治理现代化，构建航天国际合作新格局。

根据白皮书，未来五年我们将一起见证
新一代载人运载火箭和大推力固体运载火箭、“问天”和“梦天”实验舱、“巡天”空间望远镜、“嫦娥六号”“嫦娥七号”等航天发射、中国空间站全面建成运营。

中国航天将深化载人登月方案论证，完成火星采样返回、木星系探测等关键技术攻关，开展下一代北斗卫星导航系统导航通信融合、低轨增强等深化研究和技术攻关，建设商业发射工位和商业航天发射场，促进商业航天快速发展，培育发展太空旅游等太空经济新业态，持续开展航天国际交流合作。

Today China State Council Information Office released the "China's Spaceflight 2021" White paper. It is the fifth white paper on China's space program, following those published in 2000, 2006, 2011 and 2016.

According to the white paper, we will witness the following events during the next five years:

• The new generation manned carrier rockets and heavy-thrust solid carrier rockets.
• Wentian and Mengtian Space Laboratory Modules.
• Xuntian Space Telescope.
• Chang'e-6 and Chang'e-7 Lunar Exploration Probe
• Complete operation of the China Space Station.

CNSA will implement the manned lunar landing project, research for the key technology for the Mars sample return project and the Jupiter system survey project, develop the new communication intergration and LEO service enhancement technologies for the next generation Beidou satellite navigation system.

CNSA will also construct new commercial space launch sites and commercial launching station, accelerate the development of commercial space launch and space tourism, and carry out more international cooperation in space technologies.

His masterful knowledge extends to naval propulsion as well. Richard has proposed nuclear gas turbines for future Chinese carriers - just the kind of bold and radical thinking SDF needs more of.

Heck, I think he might actually be Kim Jong Un himself. Lucky us indeed.
