MISSION MODULE:  VentureStar will employ a unique approach to payload processing.   All operations will be done "off-line".  The payloads and, if necessary, upper stages will be integrated into the VentureStar Mission Module in a separate clean room facility.  Prior to launch, the integrated unit will be mated into the VentureStar payload bay.  This approach, which is similar to the one used by Kistler Aerospace on the K-1 launch vehicle, decouples payload and launch vehicle processing and should simplify launch operations.VentureStar will employ a unique approach to payload processing.   All operations will be done "off-line".  The payloads and, if necessary, upper stages will be integrated into the VentureStar Mission Module in a separate clean room facility.  Prior to launch, the integrated unit will be mated into the VentureStar payload bay.  This approach, which is similar to the one used by Kistler Aerospace on the K-1 launch vehicle, decouples payload and launch vehicle processing and should simplify launch operations.
