Only the CZ-2F pad has light poles of that type and the launch pedestal is not their so the last picture does not correspond to this upcoming launch.

There are reports that at least one co-passenger might be on board (according to https://twitter.com/cnspaceflight/status/764031468506984448 it's some "Exosphere atmospheric research satellite" thingy. Dunno what it is unfortunately.....)

Apparently CCTV's news channel (channel 13) might be carrying this one live! Can someone who can use their online streaming check and see if that's true?

Also there is apparently a third satellite - in fact a Spanish one! Does anyone know which one is it?

An observation:

Yesterday evening, while channel-surfing through some of the foreign-sourced cable channels carried as part of our cable package, I stumbled across, in progress, a few minutes of coverage about this satellite on a CCTV news program.

Explaining the quantum concepts, in English, was causing some of the news team to "fluff" more than usual for professionals!

I don't remember which CCTV channel this was originating from.

The explanations appeared ok, and they showed what appeared to be satellite construction and processing video footage.

The producers threw in some space/star field footage, including Voyager, that appeared to have little or nothing to do with the story at hand.

World's first quantum communication satellite "Micius".

The name "Micius" is likely a translation artifact. "Micius" is the latinized form of "Mozi" and it is unlikely, that the Chinese use the latin form of the name of the Chinese philosopher.

So looking now like three payloads were launched if only we can confirm and find out the name for the other Chinese payload.

Found it: the satellite is named Lixing-1 and comes from CAS' Institute of Mechanics. Their press release mentioned that it will move to a grazing orbit of 100-150 km altitude so I guess its mission is related to exosphere and hypersonic flights.

Does Lixing-1 have two character abbreviation like LX-1 or something.
So a GOCE type mission except not Gravity related.

Jiuquan, the name of the space center and the local town, translates roughly as "Whiskey Springs". It is said to be named for an incident in about 120 B.C. in which Huo Qubing, a young but very successful Han general, was given a supply of expensive liquor by the emperor as a reward for a major victory and, instead of keeping it for himself, dumped it into the local water supply so his men could share it.

After some TLE cross-tagging confusion, it's now clear Lixing-1 lowered its orbit on Aug 16 to 124 x 140 km,
a remarkably low orbit. Latest TLE I have is Aug 19,  122 x 132 km - either it's using propulsion to counteract
drag (most likely) or it's super dense.

Some technical details of the feat beyond what the press release says:

- Entangled photons use the "parametric down-conversion" technique by which the polarization of two 810nm near-IR photons (produced by the injection of 405 nm violet light from a laser diode into a K(TiO)PO4 crystal) are entangled: one vertical and one horizontal, in superposition (|V>1·|H>2+|V>2·|H>1)/√2.

- Entanglement verification is made through the Clauser–Horne–Shimony–Holt, or CHSH method, measuring the photons in 4 different polarization orientations, yielding different results if there is no entanglement (i.e. if there are only classical/local correlations). This was achieved at the 4-sigma level.

- Lowest losses achieved were <64-82 dB over ~1200 km, when 240 dB would be expectable in a similar experiment through fiber (whose record stands at 600km), since losses increase exponentially. Consequent errors in scamkey transmission are much reduced thanks to the now proven satellite link, which dramatically improves S/N (~8:1).

- Even with ideal fiber transmission, satellite link losses are better by at least 4 orders of magnitude. Presently, they are 12-17 orders of magnitude.

The story was also carried on this week's Science in Action on the BBC World Service radio.

Is the satellite correctly called "Mozi" or "Micius"?

Both. Just as 'Confucius' (latinisation) is the same as 'Kongzi' (Chinese).

The ground station (Ali,Tibet,China) was building the link between the satellite and ground on Dec 10 2016

(Moderators, I do not know the best location for this thread. It isn't about a Chinese launcher, nor about an advanced propulsion system. It is not just theory, but actual experimental results in space at the current time. If you decide a more appropriate place, please relocate the thread. I could not find anything regarding the experiments on this satellite via a search. If I missed it, please merge or delete.)

A Chinese satellite has generated entangled photons and then beamed them to locations 1200 km apart, almost an order of magnitude higher than any previous successful attempt. Quantum communication is described as possible.

A fair chunk of the article is dedicated to the Micius mission, including talking with Jian-Wei Pan, as well ending with a short piece on China’s general advances in space.

China’s great leap forward in science

Chinese investment is paying off with serious advances in biotech, computing and space. Are they edging ahead of the west?

Using the “Micius” satellite, researchers achieved entanglement-based quantum key distribution (QKD) between two ground observatories in Delingha and Nanshan (China), separated by 1,120 kilometres.
