[FPSPACE] doubts about Fobos Grunt and YH-1

[Paolo Ulivi]

Doubts doubts doubts...
I was wondering about the latest F-G/YH-1 stack configuration, which 
look something like this

assuming that a mission profile "à la Fobos" is used, the Fregat stage 
at bottom places the stack into Mars orbit and then circularizes the 
orbit to one close to that of Phobos. After this, F-G and YH-1 are 
released. Does this mean that YH-1 will not enter the announced 800 x 
80,000 km orbit but will instead enter a circular one 6,000 km above the 
planet?
I see no way YH-1 can be released from this stack just after orbit 
insertion as initially announced, unless the Fregat is used only to 
enter Mars orbit and the circularization is carried out by F-G onboard 
engine...
any idea? suggestions?
