Why Progress M-19M is using 2 days randezvous?

Cassidy and Parmitano will remove and replace a Space-to-Ground Transmitter Receiver Controller, install a radiator grapple bar and retrieve a mast camera from the Mobile Base System. They also will install the first of two jumper cables on the Z1 truss. Their final tasks will include the retrieval of samples from the Materials International Space Station Experiment and the Optical Reflector Materials Experiment. If time permits, a variety of “get-ahead” tasks could be performed, including temporary cable stowage, releasing clamps on the S1 truss and relocating an articulating portable foot restraint.U.S. spacewalk 22 – will see Cassidy and Parmitano work to remove alignment guides from the radiator grapple bars and move them to External Stowage Platform-2. Next they will work to route networking cables to the upcoming MLM location and remove insulation from one of the station’s Main Bus Switching Units. After installing a second Z1 truss jumper cable, the two astronauts will work to replace a camera on the Japanese Experiment Module Exposed Facility and install cables for the fixed grapple bar’s module’s power and data grapple fixture. Their final task will be to relocate the Wireless External Transceiver Assembly and the Video Stanchion Support Assembly from Camera Port 8 to Camera Port 11 on the truss. If time permits, the two spacewalkers will work to finish up get-ahead tasks from the previous spacewalk including the release of clamps on the S1 truss and relocating an articulating portable foot restraint.

Ben E, I do know exactly that Volkov is assigned to Soyuz TMA-18 crew, but I do not know exactly the same about Ovchinin, that is why I have removed him from the schedule.
Anik, what is the reason for Soyuz TMA-09M remaining until possibly the end of November? Is this a return to 'direct handovers' of expedition crews?Thanks.
No mention of Cygnus??

No, I am sorry, but, as Galactic Penguin SST said, I will wait results of first Antares launch.
For spending of all "U.S. propellant" in ATV-4 there will be possibly a deboost of ISS orbit from 410 km to 380-390 km mean height at the end of 2013.
Why the need to expend all the propellant
it will have a negative effect on the ISS?
