AFAIU, the full name is Hainan Wenchang Satellite Launch Center, the short form is Wenchang Satellite Launch Center (WSLC)

Ok, changing the threads title.

Some latest photos by Worldview 1 taken on January 19th seems to show that WSLC will feature two VABs and two launch pads, although the resolution is too low to show the details...
Hmm....where can I apply for the job of United Launch Alliance internet cheerleader?

Could you provide an English version of the captions, please?

Here you go (note that the identifications are merely speculation between forum members on a Chinese aerospace forum).

If there are indeed two CZ-5 VABs then I wonder how many vehicles each VAB could accomodate at once?   Maybe four simultaneous assemblies?

The big question is whether the CZ-7 series will be launched from WSLC? So far I have not seen a clear answer (even from Chinese soruces).

P.S. The Chinese have little problem with YF-100, their next generation kerolox engine (it's already doing gimballing and acceptance tests right now), but their "half-a-Vulcain" YF-77 engine for the CZ-5 is seriously behind schedule. This, plus that the Chinese has only just completed a prototype for the 5 meter diameter hydrogen fuel tank, means that first launch in 2015 will be hard to hit. And the CZ-7 does not seems to be a priority right now....

Very interesting.

Just for the record, this showed up this morning:

China's New Rockets Expected to Debut Within Five Years
2012-02-05 21:32:25   
Xinhua     
Web Editor: liuranran

China's new generations of the Long March rocket family, Long March-5, -6 and -7 are expected to make their maiden flights in the next five years, a rocket scientist [, Yu Menglun,] has said.

[snip]

Long March-5 rocket will be using non-toxic and pollution-free propellant. It has a maximum low Earth-orbit payload capacity of 25 tonnes and geosynchronous orbit payload capacity of 14 tonnes.

The Long March-6, which is designed to be a high-speed response launch vehicle, has a minimum of 1 tonne of sun-synchronous orbit payload, according to the scientist.

The Long March-7 has a maximum low Earth-orbit payload capacity of 13.5 tonnes and 5.5 tonnes of sun-synchronous orbit payload, he said.

[snip]

Currently, a fourth launch center is being built in Wenchang in the island province of Hainan. The Wenchang launch center is expected to be put into use within two or three years, according to Yu.

I would like to see some discussion of the requirements that led to the LM-6.  To my eye it looks military, but that's probably just me.

I would not be ready to immediately interpret the image as showing sites for "two VABs".  The diverging path might lead to a parking/service area for mobile launch platforms, for example.  Or it might run to a payload preparation facility.  Etc.  Two completely separate vertical assembly buildings doesn't make sense to me, given the dual high-bay setup at Jiuquan.  Also note that Jiuquan has separate road and rail rights of way running toward the pad areas from different directions.

Does anybody know how much it would cost to buy the high-resolution image from DigitalGlobe?

I thought I'd posted this earlier, but don't find it now. At any rate, it's another browse image taken on 5 June 2011. There seems to have been a fair amount of change between then and the Jan 19 image.

Translations, por favor.  Also, the X= and Y= in the fourth picture look like they might some sort of geodetic coordinates; are they, and if so, what kind?

And most important of all, what are the good restaurants in the area?  I don't rule out a trip to Hainan once the CZ-5 starts flying.

The single path splitting at both ends on the photo is very similar to the existing MLP track layout at Jiuquan's South Launch Site 1. At one end the VAB has two bays; at the other there are two launch pads.  A simple and logical arrangement.

Translations (with kind help of Chinese friends)
VAB and launch pad photo labels, top to bottom:

1. Long March 5 assembly building 1
2. Long March 5 assembly building 2
3. Transfer route
4. Launch Complex 1
5. Launch Complex 2

Posts beside road:

Left Post:                                      Right post:
"Restricted area - military base"        "Army construction area"

Sign with numbers:
"Construction Company"
"078 Project number 802"

On plans: "Not for construction" or "Draft only"

5. Launch Complex 2

A somewhat belated thanks for the translations.  It seems to me that the most significant parts are the numbers "1" and "2".  Are those signs that some sort of campaign requiring multiple -- or at least two --  launches is contemplated, rather than a series of essentially independent launches?

It's a backup, in fact ,for every mission, they made two spacecrafts, when one failed, they use another as soon as possible, but after launching, launch pad normally need maintenance, so shift to another one.
