I wonder, do we need two threads?
One for facts and news.
The other for speculation, discussion, ect.
The reason I am asking this is people like Jim O, Liss, ect are providing excellent updates on what is going on, but at the same time there are questions and thoughts that might be better handled in a different thread.
For instance. I keep wondering in the back of my mind the following.
There are really two types of propellant tanks on this mission. Those that are used at Mars and those that are used for Earth departure. One would assume that the Mars tanks are built to prevent freezing using heaters, insulation, ect. Since the tanks used for leaving earth are used and discarded in the first few hours of flight they have no need for that extra insulation, heaters, and thermal control. So how long in LEO until they start having problems with fuel freezing preventing earth departure?
Second, Jim keeps comparing this to USA 193. Is it really the same, the propellant tank was buried inside of USA 193 providing protect against reentry. Phobos-Grunt's tanks are not buried in such a manner. Will the exposed tanks really behave in a similar manner on reentry? I suspect with the exposed tanks they will breach early and burn? But that is pure speculation, and I am not trying to take a swipe at Jim O here.
And now with that rambling I will report myself to Chris...
