Big Day of Transfers for Crews
Today is a big transfer day for the STS-128 and Expedition 20 crews. The COLBERT treadmill is going aboard the International Space Station. It will go into the Harmony node temporarily, but its permanent destination is Tranquility node 3, which is slated to arrive early next year. In preparation for the replacement of an ammonia tank assembly during the first STS-128 spacewalk, the last of the ammonia and nitrogen was vented from the expended tank. While venting the gases, the space station's control moment gyroscopes were used for attitude control.
