ZiYuan-1 (2C) CZ-4B, Taiyuan launch - December 22nd, 2011

[Satori]

The ZiYuan-1 (2C) Earth observation satellite will probably be launched on December 15 from the Taiyuan Satellite Launch Center

A tentative translation into English for the data in this article (which also gives data on ZY-3):

ZY-1-2C:

2 HR cameras: spatial resolution: 2.36m Joint swath: 54 km

Panchromatic multispectral camera: resolution  5m and 10 m, swath  60 km

ZY-3:
4 cameras: "front, "back","facing" and "multispectral facing"

"front" & "back" cameras: resolution 3.5m, swath: 52.3 km

"facing" camera: resolution 2.1m, swath 51 km

"multispectral facing" camera: resolution 6 m, swath 51 km

Hmm... what does Mao Zedong's birthday have to do with this launch? 
Looks like December 26th is the new target date for this launch.

[Galactic Penguin SST]

This guy said that the launch is on December 23rd.

BREAKING NEWS: The launch could happen within the next few hours! 
If the spacecraft is aiming for the same lighting conditions in the Sun-synchronous orbit as the preceding CBERS missions, then the launch time could be around 03:15 UTC, give or take 15 minutes.

Looks like it's rather cold there...

Spectators has arrived at the viewing area...

[Chris Bergin]

Well if spectators are arriving, that'll be for a launch!

Great work keeping an eye on this, Galactic Penguin SST! Rui will be alseep, so I'll see if I can write an article

Is this:

"ZY-1-2C:

2 HR cameras: spatial resolution: 2.36m Joint swath: 54 km

Panchromatic multispectral camera: resolution  5m and 10 m, swath  60 km"


All we have on the satellite?

Nice surprise! If this launch takes places, it will mean that China has for the first time surpassed the US in yearly launches!

I believe it has few changes from the original Sino-Brazillian CBERS satellite, other than a better data compression ratio...

[Galactic Penguin SST]

Already at T-5 minutes and counting....

[Chris Bergin]

Cool. Actually have enough info for an article (thanks to Rui's work on the launch center and the vehicle, so we're good!)

Will be nice if someone posts a launch image (I'll accredit) otherwise I'll use stock.

That's interesting! This is China's record +2, but what was the year for the US record? I might use that angle

There are 18 orbital launches from the US in 2011 (3x STS, 3x Delta II, 3x Delta IV, 5x Atlas V, 2x Minotaur I, 1x Taurus, 1x Minotaur IV). This will be the 19th Chinese orbital launch attempt in 2011 (out of 21 predicted in early 2010!). Last year China and the US tied for 15 orbital launches each.

Excellent!
