SpaceX Update: COTS Demonstration Flight 1 (with photos)
"On September 15th we completed a successful wet dress rehearsal (WDR) which involved rolling the rocket out to the pad, loading it with propellants, performing a complete launch countdown sequence to just before ignition, and then unloading the propellants and returning the vehicle to a safe state. This latest wet dress rehearsal included new steps and sequences necessary to accommodate the operational Dragon spacecraft. Prior to the successful WDR, we completed our first integration of a Falcon 9 and an operational Dragon spacecraft. We integrate Falcon 9 and Dragon horizontally in the hangar. This makes payload processing easier, and also eliminates the large expense of building and maintaining a vertical mobile service tower."
