I haven't checked it, but it seemed to me that the rate of reboosts didn't change drastically since the ATV reboosts.
I don't understand why they still need Progress-assisted reboosts at this high altitude
The reboost of ISS orbit, which was planned on August 31st, was divided on two maneuvers with unknown dates for now. The purpose of the first maneuver will be a determination of actual thrust of Progress M-12M engines for a performing of next reboosts more precisely
I noticed on another thread (http://forum.nasaspaceflight.com/index.php?topic=26182.msg784592;boardseen#new) a diagram showing the final configuration of the RS, with Pirs at the Nadir port of the MLM.Sure that's not the plan, but just checking?
Per today's ISS Weekly Planning Conference, the August 31st reboost is cancelled.
according to this schedule, the next docking to SM Aft will be ATV-3!
the following line should be deleted from the schedule, since Progress M-12M is lost
