THE best, no "one of"!

THE best, no "one of"!

Depend on how you see it. It uses LH/LOX which is cheaper to made and safer since its is not as toxic others. American Delta IV uses LH2/LOX which is very expensive to made which is one of the reason why the launch is so little of only 12 despite debut for 12 years.

CZ-5 GTO payload is only rival by Delta IV for extra 220kg while Russian Angara-5 GTO is no where closer to CZ-5 GTO 14 tons payload.

I meant to say the photo was the best I have seen.

I think you mean RP-1/LOX.

SJ-17, the satellite that carried by CZ-5, is now moving on the GEO orbit!

Orbit of SJ-17

A quick comparison against Japan's Himawari 9, which was launched 30 hours earlier than SJ-17. But Himawari 9 is currently still struggling on GTO (Geostationary Transfer Orbit), far from GEO. I guess it needs another one week at least to reach the GEO.

In addition, Himawari 9 is burning its own fuel for the move from from GTO to GEO. Guess how costly it is? Himawari 9's launch mass is about 3.5ton; but dry mass (mass without fuel) is only 1.3ton!

The comparison clearly shows the advanced performances of the YZ-2 upper stage and the electric propulsion system of SJ-17 satellite.

I watched the whole recording of CCTV live broadcast, two hours worth of video clips. It strikes me that how young those Chinese space engineers are, those boys and girls worked "7/11" and "5+2" ! That is where Chinese strength really is, and will not be matched for long time to come! The guy who was calling the whole show, No 001, is barely into his 30's. Just imagine what they can do in the next 20-30 years, provided China is not in the deep shtt of "democracy" abyss.

The "01" commander of the CZ-5 launch!

Nice Information, bro

This is other Evidence, the Power of China's Space Technology

Let's wait, 2000s born Chinese will soon get enrolled in university.
The 1980s generation will be soon replaced by new blood.

SJ-17 had Direct Insertion to GEO which only the China and the USA (ULA) are currently capable of to all orbits

Proton-M/Briz-M and Proton-M/Blok-DM have been doing direct GEO insertion for a long time. In fact, no Russian satellite has an apogee kick engine.
Zenith/Block-DM and Zenit/Fregat can do it. Even Angara-5/Briz-M can do it with low performance.

China's next generation Hall-effect thruster is started on the SJ-17 satellite! The new Hall thruster is designed to improve the mobility and lifespan of China’s space assets.

2016年11月23日 17时18分51秒新闻网

哈工大报讯（报宣 文/图）11月3日，由我校能源学院于达仁教授团队、材料学院特种陶瓷研究所和航天五院502所联合研制的我国新一代磁聚焦型霍尔电推力器HEP-100MF在实践十七号卫星上采用，该卫星搭载“长征五号”运载火箭在海南文昌卫星发射中心发射成功。11月22日，推力器在地球同步轨道点火成功，标志着磁聚焦型霍尔电推力器在国际上首次实现空间应用。

于达仁教授团队针对传统霍尔推力器喷流发散角大，束流对壁面的轰击降低推力器的寿命、比冲和效率等问题，在国家杰出青年基金、国家自然科学基金创新研究群体和基础科研等项目支持下，开展了等离子体流动控制和磁聚焦方法研究，先后突破了霍尔推力器的宽范围磁聚焦技术、热电磁耦合设计技术、低频振荡控制技术、低功耗高可靠空心阴极、耐溅射氮化硼特种陶瓷材料等关键技术，实现了航天飞行样机的小羽流发散角高性能可靠稳定放电，羽流发散半角15°，居国际领先水平，比冲较国际同类型号SPT100提高20%，大幅降低了推力器燃料消耗和羽流对航天器的影响，为我国新一代长寿命航天平台提供了具有自主知识产权的新一代霍尔电推力技术，可广泛应用于空间站、深空探测、高低轨地球卫星轨道控制等领域。

It seems like a significant progress:

"It is the first time a Magnetic Focus Hall Effect Thruster being used on a spacecraft! "
