This is interesting. What is different about the situation which results
in M54 staying at the station instead of leaving just before M55 arrives
which is the normal procedure ?

Will they move M55 to the aft port after M54 leaves so that M55 can
perform reboosts ?

I thought you were paying attention...see Jacque's post of SS05-057 on
the 9th:

"Station managers are evaluating a proposal from Russian engineers to
delay the scheduled Dec. 20 Progress undocking. The proposal would
leave the Progress attached to the station longer, allowing the crew
additional time to use it for trash disposal and to use its oxygen
supply. Regardless of whether the Progress is docked or undocked,
launch and docking of the next Progress is Dec. 21 and Dec. 23. The
new Progress will deliver food, water, fuel, air and holiday gifts
for the crew. It will be the 20th Progress to go to the station."


As to your second question, Idunno.
