There was a now deleted photo posted on a forum showing SAST engineers standing in front of the Shanghai train station heading for some unknown launch site, with a banner that reads "Gaofen 10 satellite testing team". ;)
So yeah, there should be a GF-10 heading up in the next 2-3 months. ;)
So your thinking possibly the following from JSLC or TSLC:
2016
September or October - CZ-4B - TSLC, LC9 - GF-10 Gaofen-10
OR
September or October - CZ-2D - JSLC, LC43/603 - GF-10 Gaofen-10
-
Likely this will be the next Chinese launch from TSLC (http://bbs.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=68942&pid=484208&fromuid=24484)?

Well, it looks like that this one is launching on August 30 GMT time...... (wee hours of the night on the 31st local time)
A2154/16 - A TEMPORARY RESTRICTED AREA ESTABLISHED BOUNDED BY: N302834E1090528-N302143E1094207-N292852E1092859-N293535E1085237 BACK TO START. VERTICAL LIMITS:GND-UNL. GND - UNL, 30 AUG 18:46 2016 UNTIL 30 AUG 19:11 2016. CREATED: 24 AUG 07:37 2016
Can someone check what launcher does this drop zone corresponds to? There are rumors that a CZ-2C will be used. ;)

Well, this fairing drop zone (in red) seems close to the fairing drop zone for CZ-4C used for FY-3B (in green)
Fairing for CZ-2C (used for YG-18) was recovered to the South

Looks like date change, coordbox&time are same as old
Also, I'm guessing T-0 is closer to 1853 UTC because GF-3, FY-3C & Chuang Xin-3 that all launched on 4C had a 7ish min difference between notam start & T-0.
-
Any idea of what kind of bird this might be?
-
With the launch time at around 3 am here I can't guarantee that I can be awake at launch time, so someone please take a look at the usual Chinese news websites after 19:30 UTC if you can. ;)

The new generation TTC ship Yuanwang is standing by for operation

We are now waiting from news coming from Taiyuan....

Two hours after the expected launch time and still no news.

Wonder if it got delayed. No locals talking about Earthquakes I take it? That's usually a sign ;)

Nowt on Weibo. And Xichang is the one that's good value for startled locals :)
-
... and no new launches in the TLEs, at least so far.
-
On 9ifly space forum, people are talking about some kind of problem with the rocket. But it looks like there was no launch. Automatic translation doesn't help much in this case.

All are speculations and not rumors. I doubt we will know whatever happened to it until those who know speaks out. :-X
-
It looks like the launch was delayed (because of some problem with the launcher?)
-
Checking Weibo, one insider has just posted several tweets that indicated that something has happened to this launch, but it's not clear whether that means a scrub or failed en route. Either way, this launch isn't our imagination. :-X

From 9ifly:
Shaanxi Public Security

# # [Shaanxi security satellite wreckage recovered] September 1, issued by a satellite launch base in the territory of the County of Shangluo Mountain satellite fall, Hill County Public Security Bureau verses Paul Squadron accompanied the launch base personnel to do the work of recovery of satellite wreckage, climb slopes the successful completion of satellite wreckage recovery tasks.

So it is apparent that the launch did took place.....
No signs of any new things in orbit?

First stage debris

-
No TLEs published so far
-
That second photo looks like the top of the first stage.
http://space.skyrocket.de/doc_lau_det/cz-4c.htm
-
The location of debris recovery in Shanyang county is coherent with CZ-4C 1st stage debris
-
No TLEs and no launch announcement... Looks like the first launch failure of 2016.

No TLEs and no launch announcement... Looks like the first launch failure of 2016.
....and half a day later it seems like the Chinese simply swept it under the rug as if nothing has happened (in 2009/11/13 they at least did acknowledge within 7 hours). That's very bad precedence...... :-X
Remember anything else other than a third stage problem will directly impact TG-2 and SZ-11's schedule, just like what happened 5 years ago. They will have to explain later anyway so why?

Doesn't seem to have been a 1st stage problem since the debris were recovered where they were expected

There are some rumors, YF40 restart failed
-
Doesn't seem to have been a 1st stage problem since the debris were recovered where they were expected
Looking closer, there is a minimum distance of 18 km between Shanyang county (where this CZ-4C 1st stage debris were recovered) and locations where 1st stages for past successful CZ-4C launches where recovered (i.e. YZ-15 & YG-27)
Not sure if this is significant...
-
Sounds like the actual 1st stage drop area was not part of the pre-announced potential drop areas
http://china.caixin.com/2016-09-01/100984300.html
-
Expected launch mission codename was 05-53
-
Fairing debris were recovered near Shengjiaba within the NOTAMed area, suggesting that flight path was close to nominal at least until fairing separation
http://hb.qq.com/a/20160901/043481.htm
-
This apparent failure would end a string of 65 consecutive orbital launch successes world-wide since early December, 2015. The previous long success string was 69 successes during 1988-89, as best I can determine.
That explosion at Cape Canaveral this morning also served notice that success remains fleeting in this business.

With the story at 16:30 local, and the photos looking like about noon, the timeline is plausible.

Very prudent skepticism!

- Ed Kyle
There are two caveats on that string of successes: The North Korean launch earlier this year was reported to have underperformed and left the payload tumbling; and I'm not sure it was conclusively confirmed that the Iranian launch in April was a suborbital test and not a failed orbital attempt (although the former does seem far more likely).
-
30 hours after the launch there's zero/nada mentioning of this incident on any state media while the F9 Kaputnik filled the Chinese headlines......
I start to really think that they want to hide the news until at least after the G20 conference, if ever. :-X

So this is the "expected" drop area? Within a town or village?
If that's true then WTF??

Well, that's problem with launching in China. People are everyone, when in places like the forest area near Shengjiaba where there is less people than the plains, but still lots of people compared to most countries. debris are bound to hit towns and villages once in a while. Which is why the space in Hainan was built.

Personally, I think it because even they are not sure exactly what happened, at least not enough to work out who to blame for it yet. Unlike the Brazil case, there is no external customer and the payload has possible military uses, so it better to keep things under the wrap than draw attention to it.

Still nothing from the Chinese media? If anything they probably won't at all now as "announcing" it days later would look even worse.

some of them appear to have been replaced with other images potentially not from this flight. USSTRATCOM has yet to find anything in orbit so far and others believe that it did not make a return to sender orbit either.

I have not seen any removal of news about 1st stage recovery, as for sites using random images from other launch es. that practice is very common in news media, since all rocket debris look the same to the average journalist and general public.

Rumors today points to the 3rd stage failing to re-ignite. Given that the usual MET for a LM-4C launch is as short as <30 minutes, I think it's safe to say the transfer orbit dips below the atmosphere..... ::)

Peter B de Selding, quoting China Great Wall, seems to confirm it was a third stage problem:
China Great Wall Industry: Long March 4C failure Sept 1 was isolated to stage only used on 4C, so other Long March variants unaffected.

No chance it's a stealth payload, right?

no just the usual civil satellite that is used by the Ministry of Defense and other ministries. Afterall some of the GF satellites are used to track the movements of the 200 and increasing number of US Naval vessels being moved to operate round the clock in the South China Sea as an escalation of allied forces.

I am not sure if the image shows indeed GF-10.

What does the cover say, what it is?
Looks indeed new to me and appears not not to be a reuse of another satellite image previously shown on a cover.

The orange text says: "Gaofen-10 satellite launch commemoration"

... and the black rectangular postmark is saying that the launch was not succesfull due to a rocket failure.

I know that LM-4C can restart its 3rd stage, but I thought that was mainly for depletion - do we know the detailed
launch profile of the 4C with the usual times of the burns?
I was under the impression that it mainly followed the old 4B profile with coast to stage 2 apogee and a single
insertion burn.
Oh, and any new news on this failure since October?

Hmm I don't think so - you can find a timeline for the FY-3C launch in the post below and the time stamps were given as follows:
The projected times of the different launch phases are visible in this picture (posted on the 9ifly Chinese space forum).
2nd stage separation: T+04:54
3rd stage shutdown #1: T+09:59
3rd stage re-ignition: T+19:09
Spacecraft separation: T+20:36
Also you can see below that the performance graph to SSO for the CZ-4 series - the 4B curve falls out much faster than the 4C one as altitude increases. I doubt that using the re-ignition just for de-orbiting the third stage would result in such a difference. ;)
Unfortunately I don't see anything announced yet since October - maybe we will see some news when it returns to service ::)
-
Thanks. I had those FY3C timings in my archive but had forgotten about them. Convincing.

Today some PDF images(with unknown source so far, sorry I can't find the full PDF) about GF-10 circulates on Chinese Weibo, which indicates the GF-10 satellite was a 0.5m resolution SAR satellite(maybe YG-29 series?)
