Thought we closed Endeavour’s payload bay doors for rollout two weeks ago, but we ended up having to re-perform a functional check today. So the doors were opened up,
and I got to support payload bay door functional checks from the flight deck! Here, looking through the observation window, the left door is closed and the right one is about to be.
The curtain covering the aft bulkhead is called a debris curtain and is used to determine the cleanliness of the payload bay when the vehicle goes from horizontal to vertical. It is removed once the doors are opened at the pad. Now the right door is coming closed,
and the doors were closed for rollout to the VAB. We will have the orbiter on the transporter this weekend. It is built by Lamborgini and has 74 tires (we call it the skateboard). Stay tuned and I’ll post pics of it soon!
