Dec 6, 2008- STS-126 landing day 5

Performed a SCAPE operation to drain a small amount of propellant from the OMS (Orbital Maneuvering System) ball cavities. If left in there, it would degrade the sealing capability of the ball valves. Didn’t have to go up, but I was dressed and just about had my air supply turned on when they finished up. Here are two of the techs in SCAPE suits working on the aft platform.

After that was finished, two other techs and I removed the flight tires from the main landing gear and installed Roll Around Tires (RATs). Took us about 5 hours, which was pretty good time. The tires weigh about 200+ pounds a piece. You can see the Renforced CarbonCarbon (RCC) brake rotors on the axle.

We are back to working 12 hour days, but at least we are keeping our shift start time. That will make it easier to handle. Expect to see the tailcone installed tomorrow– it should be ready to fly out Sunday or early Monday. Will continue to post pics until I leave for home.

Got moved from Lancaster to the town of Tehachapi today before work. Small town in the mountains where they have a wind farm– 4,600 windmills producing over 1.4 billion kilowatts a year for California. Took a shot of what I could see from my hotel area. It is windy today so they are pumping out some power!
