[FPSPACE] Tiangong -- is it even feasible?

[Phillip Clark]

Maybe you are over-estimating the Chinese plans.

I have always considered the Chinese space lab (call it what you will - the plethora of names is making my brain hurt!) based upon CZ-2F class launches would be hosting missions of up to a month at the most: most likely, three-manned visits of around 10-14 days.

The longer flights, I considered, would come along once the CZ-5 is introduced with its greater lifting power.

We know that one of the Soyuz designs - Soyuz-P?? - was for the launch of a small lab module which looked like the original drawings of Cosmos 186-188, and then piloted Soyuz craft would visit them.   Has there ever been an indication of how long such visits would be?   Only a week or two, I would guess - not in excess of a month, anyway.

Just thought that I would add to the confusion.

  My first estimate for a 2-man crew on a 100-day mission is that
  it would take about 1400 kg of consumables -- o2, food and water, 
  LiOH scrubbers -- to keep them alive 'open loop'.
