If the shuttle is to be retired by 2010-2011, and I don't know of any immediate plans (3-4 years) for the 3 MPLM's Leonardo, Raffaello and Donatello after their servicing missions to ISS. And since it seems that living space or at the very least, storage space has always been at a premium on ISS, why not just leave Donatello attached to Node 2 (same place the Centrifuge module was going to be) permanently after the fourth-last shuttle mission, flight 19A. By coincidence, Donatello is the most capable, as it can carry powered payloads. In this mission, Donatello will deliver equipment for enlarging the station crew from three to six astronauts. Depending on the purpose, it can be equipped with power, data and fluid to support refrigerators or freezers, or it can be used to stow excess materials. All three MPLM's include components that provide life support (oxygen, water and temperature control), fire detection and suppression, electrical distribution and computer capabilities. As extra living space for 6 crew members, extra storage space for contingency or normal ISS usage, it's scheduled to go up anyway and after the cancellation of the Centrifuge module, it seems like just another waste of money to bring Donatello back to earth to be retired. What do you folks think? <br />
