Getting Ready for Moving Day

Today ISS station commander Peggy Whitson and flight engineer Yuri Malenchenko executed a 6 hour and 55 minute spacewalk to prepare the newly arrived Harmony module for a move next Wednesday from its current temporary location to its permanent home attached to the Destiny module. In the meantime, on Monday, the Pressureized Mating Adapter 2 (PMA-2) will be moved from its current location on the Destiny module to the Harmony Module. This complex dance will enable visiting spacecraft to dock with the station through the Harmony module and will free up the current location of Harmony for the delivery next month of the European Columbus module and later the Japanese Kibo module. These additions will substantially expand the usable volume of the station, making it much easier to perform scientific experiments.

On one of the upcoming shuttle missions, repairs must be made to the starboard SARJ unit, which controls the orientation of the starboard solar arrays, before full power becomes available, enabling a full spectrum of activities to take place. Considering all the work that remains to be done and the looming 2010 retirement of the shuttle, just about all the contingency time that was originally in the schedule as been used up.
