Endeavour is being prepared for delivery to KSC this week. Today, the new orbiter is being mated to the new 747 Shuttle Car- rier Aircraft using the Orbiter Lifting Frame. The first leg of the cross country ferry flight, from California to Texas, is scheduled to begin tomorrow morning. A refueling and overnight stop is planned at Ellington Field in Houston, Texas. The journey, from Texas to Florida, will continue Friday. Pending favorable weather conditions, Endeavour's es- timated time of arrival at KSC is midday Friday. Once demated from the 747, Endeavour will be towed to the Orbiter Processing Facility where the tail cone, ferry flight kit items, the two simulated orbital maneuvering system pods, and mock forward reaction control system will be removed. Endeavour will then be towed to the Vehicle Assembly Building for powered down work.
