Title: Tiangong and Tianzhou propellant loads
Post by: Phillip Clark on 06/25/2018 05:15 pm

The answer is probably going to be "no", but here goes .....

Has anyone seen Chinese figures to show the propellant masses on Tiangong 1 and 2 at launch?   We know from the pre-launch commentary that Tiangong 2 was only partially-fueled at launch to increase the science payload and because it was expected that Tianzhou 1 would top up the Tiangong propellant tanks.

Also, with Tianzhou 1, do we know the total propellant mass transferred to Tiangong 2?

Many thanks to anyone with the numbers!

Ah, good point, I had not taken that into account in my calculations
