They are that confident about mission success.

really hope everything would go smoothly tomorrow, i couldn't help getting a little nervous, seeing that there seemed to be unusually more pre-launch publications this time.....

Some good screen captures of the Wentian module. It has eight internal experimental cabinets and an external mounting platform that can accomodate 22 experiments. It also carries 1.5 tons of propellant.

The taikonauts have a 'free-activity' space of 50 cubic meters, which is divided among three sleeping areas, a bathroom facility, and a storage room. The internal temperature is kept at 24°C with a humidity of 40%. The noise level of the working area does not exceed 60 decibels, and for the sleeping area it does not exceed 50 decibels.

Look like Chinese Lyappa (What's it called?) is much more advanced than their Russian counterpart

CMS should use aerial work forklifts from Dingli instead of these Haulotte lifts. They apparently have similar global market share and products. Moreover, these landmark state programs create reputation for these machinery companies.

I can't say it is more advanced. The Chinese one is much larger and longer and having a joint in the middle. So it is more complicated. But the complication is probably due to the different location of the socket instead of being advanced. The Chinese one's socket are placed further away from the docking interface, demanding a longer arm which has to be folded during launch which means the extra joint.

The purpose of Lyappa arm is only for the initial docking and moving of the module, it would hardly ever be used for a second time. So I don't think there is any more function it could have.

Long time ago there were statements that new Wentian arm will be combined to existed one, creating single extended arm... I doubt they would sacrifice that much weight and engineering for just single usage.

From what I recall, the arm on Wentian CAN be combined with the existing arm WHEN NEEDED. Otherwise, it is used independently.
