Dry run being done right now for the launch team and the astronauts out at the pad- they flew in yesterday. They do everything right up to lighting the engines and boosters so everyone knows how its going to go on launch day. Here are some cool shots of Discovery rolling out to the pad at a blistering 1 MPH– (Check out the guys along the railing of the Mobile Launch Pad (MLP) atop the crawler for scale).
This is a shot of it rolling out of the VAB after midnight along the crawlerway. The building to the left is the LCC which is where the firing rooms are.That is the room where you see everyone sitting behind consoles during the launch countdown. There is a blast shield (the shutter looking things) over the windows. The next pic,
is Discovery enroute outside of the pad area (credit NASA for most of my pics- I’m just picking out the cool ones).
