时隔 6 年，中国第二颗量子通信卫星成功发射升空
After 6 years, China's second quantum communication satellite was successfully launched into space

At 12:12 on July 27, the world's first quantum micro-nano satellite "Jinan-1" was successfully launched on the "Lijian-1" carrier rocket at the Jiuquan Satellite Launch Center. At present, "Jinan No. 1" has entered the established orbit, the solar panel has been successfully opened, and the on-orbit test work will be carried out soon. The successful development of the "Jinan No. 1" quantum micro-nano satellite will enable my country to realize real-time satellite-to-ground quantum key distribution between micro-nano satellites and miniaturized ground stations for the first time in the world, and build a low-cost and practical space-earth integration Quantum secure communication network.

The "Jinan No. 1" micro-nano quantum satellite was led by Hefei National Laboratory, and was jointly developed by the University of Science and Technology of China, the Jinan Institute of Quantum Technology, the Institute of Microsatellite Innovation of the Chinese Academy of Sciences, and the Shanghai Institute of Technical Physics. With the support of the Jinan High-tech Zone Management Committee, the Jinan Institute of Quantum Technology is responsible for organizing the development of ground application systems, and as a user, it conducts the overall verification of quantum key distribution application technology.

The "Jinan-1" quantum micro-nano satellite is the second quantum communication satellite launched by China after the launch of the "Mozi" quantum science experimental satellite in 2016. Based on the research and development and experiments of the "Mozi" quantum science experimental satellite, the research team successfully tackled key technologies such as low-cost miniaturized quantum key distribution technology, real-time key extraction technology, etc. The nano-satellite platform is developed to reduce the weight to about 1/6 of the Micius, increase the frequency of the light source by about 6 times, and improve the timeliness of key generation by 2-3 orders of magnitude. With the miniaturized ground station system, real-time satellite-to-earth quantum can be completed. Key distribution experiment, and carry out technical verification and application promotion.

The successful launch and in-orbit operation of the "Jinan No. 1" quantum micro-nano satellite will be followed by a demonstration of commercialized wide-area quantum communication network applications through a miniaturized satellite ground station in Jinan, which will help my country expand its international presence in the field of space quantum communication. Leading position, realizing the leap-forward improvement of national information security and information technology level.

At 1:40 on August 16, 2016, my country successfully launched the world's first quantum science experimental satellite "Mozi" with the Long March 2D carrier rocket at the Jiuquan Satellite Launch Center. Then humans completed quantum communication between satellites and the ground for the first time.

A statement from NASA Administrator Nelson, distributed just now by the agency, about today’s Long March 5B core stage reentry.

The People's Republic of China (PRC) did not share specific trajectory information as their Long March 5B rocket fell back to Earth. All spacefaring nations should follow established best practices, and do their part to share this type of information in advance to allow reliable predictions of potential debris impact risk, especially for heavy-lift vehicles, like the Long March 5B, which carry a significant risk of loss of life and property. Doing so is critical to the responsible use of space and to ensure the safety of people here on Earth.

China launches reusable experimental spacecraft
JIUQUAN, Aug. 5 (Xinhua) -- China on Friday successfully launched a reusable experimental spacecraft using a Long March-2F carrier rocket from the Jiuquan Satellite Launch Center in the northwest of the country.

After a period of in-orbit operation, the spacecraft will return to its scheduled landing site in China. It will test reusable technologies and in-orbit service technologies as planned during its flight, providing technological support for the peaceful use of space.

The launch was the 18th mission of the Long March-2F carrier rockets.

HELSINKI — China is progressing with the development of two super heavy-lift rockets for crewed missions and infrastructure launches to the moon, according to officials.

The new launchers are designed to allow China to conduct short-term lunar landings before 2030 and send large pieces of infrastructure to the moon in the 2030s respectively.

Though China’s government has not formally approved a crewed lunar landing, work on the necessary elements of such a program is underway and the country’s space actors and state media are openly talking of its lunar ambitions.

Some Moon Landing Ideas from 2007
The first, the Long March 6 heavy rocket (not the actual Long March 6)
The second , six Long March 5 rockets launch the lunar module and the manned spacecraft respectively
（6 rockets instead of 4 as the public guessed, probably because the spacecraft is not Shenzhou but heavier）

Well this is a different approach to creating a reusable launcher rather than go clean sheet they are instead planning on revamping an already existing launcher, and one that has been around three decades.

China’s main space contractor plans to revamp a highly successful, 30-year-old Long March rocket model to adapt to the trend towards reusability in the launch sector.

Despite this success the China Aerospace Science and Technology Corporation (CASC) and its subsidiary, the Shanghai Academy of Spaceflight Technology (SAST) are looking to greatly change and improve the rocket, according to a report from official industry newspaper China Space News Aug. 24.

CASC states that the rocket will in the future be upgraded to use engines powered by kerosene and liquid oxygen, replacing the hypergolic YF-21C and YF-24C engines currently in use.

A reusable Long March 2D and ditching hypergolic fuels could cut launch costs, Tan said.

The move appears to be part of a long term plan to develop reusable space transportation systems.

Is it me do the re-entry module shape on the models pictured look different than a soyuz re-entry module? Are these the pictures Mark Wade based his old chinese capsule design on? Updated *** In the link it states the capsule is different quote "Interestingly, the shape of the return capsule of this design is closer to the conical/truncated cone shape of the new generation of manned spacecraft, rather than the bell shape initially imitated by the Soyuz and later Shenzhou spacecraft." end quote. I guess if I read it before asking!!! lol

What do people think of China’s possible approach to creating a reusable launcher that of revamping an existing booster rather than going for a clean sheet design like Space X?

Although it looks like there is a repeatable or LOX variant of the Long March 2D in development
But the Long March 2D here is actually a test platform. The real plan is a commercial rocket with a diameter of 3.8 meters.

I thought they were two separate developments. A fully commercial launcher and also an adapted government launcher.

In fact, China has more than two plans for repeatable launch vehicles
