The ISS Progress 26 vehicle rolled to its launch pad Tuesday loaded with 
5,111 pounds of food, fuel, air, water and supplies. The cargo craft 
also contains new Russian computers, cables, connectors and a commanding 
unit. The commanding unit will replace an identical unit on the station 
when the upcoming STS-118 mission visits in August. The unit is 
suspected of causing the computer failure during the STS-117 mission in 
June.

On the eve of the undocking of the Progress 24 cargo ship from the Pirs 
docking compartment, the crew members completed the stowage of discarded 
items no longer needed on the station. They closed the hatch, conducted 
leak checks and activated the ship's systems for Wednesday’s undocking 
scheduled for 10:05 a.m. EDT. The Progress engines will be fired at 
about 2:40 p.m. to begin the descent to Earth's atmosphere, where it 
will burn up 30 minutes later.

The crew members also did a timeline review with flight controllers 
Tuesday as they prepare for the launch of Endeavour on the STS-118 
mission Aug. 7.
