(09/28/1998) --- Seen from behind, the orbiter Atlantis approaches the entrance of Orbiter Processing Facility 2 (OPF-2) where it will undergo preparations for its planned flight in June 1999. Atlantis spent 10 months in Palmdale, CA, undergoing extensive inspections and modifications in the orbiter processing facility there. The modifications included several upgrades enabling it to support International Space Station missions, such as adding an external airlock for ISS docking missions and installing thinner, lighter thermal protection blankets for weight reduction which will allow it to haul heavier cargo. OPF-2 consists of a 2,700-square-meter (29,000 square ft.) high bay. The building measures 29 meters (95 ft). high, 121 meters (397 ft.) long and 71 meters (233 ft.) wide
