TZ-1 Tianzhou-1 is schedule for launch in 2016. This will be the first Chinese logistics mission to a space station.

From Xinhua: China to launch Tianzhou-1 cargo ship in 2016 to rendezvous with space lab.

Tiangong-2 on the CZ-5?   That's what the article says!   Surely something is wrong here.

Do we know yet how big TG-2 is going to be? If they've gone big, CZ-5 would be the only option, right?

Tiangong 2 is supposed to be the TG 1 back-up with some modifications, so I would expect roughly the same mass.

I had a look at Chinese language press - they say CZ-7. An error in translation then, most likely.

China's first cargo spacecraft to leave factory (Xinhua)

"A review meeting was convened last Thursday, during which officials and experts unanimously concluded that the Tianzhou-1 cargo spacecraft had met all the requirements to leave the factory.

The take-off weight of Tianzhou-1 is 13 tonnes and it can ship material of up to six tonnes."

Four propulsion system chambers at the rear, unlike two on Tiangong.   Maybe because the cargo freighters are nearly twice the mass at launch?

That thing is probably the pressurized compartment of the 2nd TZ unit - wrong launch site for Shenzhou I'm afraid. ;)

Launch is scheduled for mid-late April.

Interesting shot of the interior.  What's the point of all that cargo if there is no one on board Tiangong-2 to unload it?!

Well either there is a robot on board or Tiangong-2 has two docking ports.

could be ballast in the bags or a loading test on the ground

Online ZachS09

I think they're just doing a propellant transfer because Shenzhou 11 was the only manned mission to Tiangong 2, so I can't imagine food, water, and experiments being launched aboard Tianzhou 1.

China's 1st cargo spacecraft to make three rendezvous with Tiangong-2

Not only 3 rendezvous and dockings, but also 3 separate tests of the fuel transfer system as well. TZ-1 will remain docked with TG-2 for a total of 2 months, with another 3 months' time flying solo.

In other news, the CZ-7 rocket has left the plant for Wenchang yesterday. Interestingly a regular cargo ship is being used instead of the special rocket transport ships the Chinese have.....  ;)

Welcome to our website:
http://www.spaceflightfans.cn/

Online Galactic Penguin SST

According to https://twitter.com/cnspaceflight/status/840490961268482048 rumors point to launch planned on April 23 at 10:20 UTC (can someone check if the orbital plane of TG-2 does cross Wenchang at that time?)

There will be cubesat deployer on board TZ-1 with at least 1 cubesat to be released during the mission.

I think I might be right here, but will Tianzhou docking with Tiangong 2 be the first time that a significantly heavier spacecraft has been the active partner in a docking operation?

Automated/unmanned, probably.
 
Apollo + APAS was way heavier than Soyuz in the 1975 rendez-vous, and it was the active part for the two docking operations performed during the mission.
Besides, Shuttle would have been heavier than Mir in 1995, no?

Good point about Soyuz and Apollo.   As for the shuttle orbiter and the Mir complex, I don't think that the ratio of the two masses was as great as that of Tiangong 2 and Tianzhou 1 which is approaching 2:1.

There are speculations that these are modules for the Chinese space telescope.

As far as I understand from the illustrations the planned sequence of joint TG-2 andTZ-1 flight activities is:
1. Launch of TZ-1
2. First docking with TG-2
3. Undocking of TZ-2 and flying around TG-1
4. Second docking with TG-2
5. Undocking of TZ-1
6. Third docking (a rapid one) with TG-2
7. Joint orbit change
8. Undocking of TZ-1 and separate flying
