Atlantis heads for the open doors of the Orbiter Processing Facility bay 2 where it will undergo preparations for launch. Atlantis returned from California atop a Shuttle Carrier Aircraft after its Feb. 19 landing at Edwards Air Force Base, concluding mission STS-98. The ferry flight began March 1; unfavorable weather conditions kept it on the ground at Altus AFB, Okla., until it could return to Florida. In the Orbiter Processing Facility, Atlantis will be prepared for mission STS-104, the 10th construction flight to the International Space Station, scheduled to launch June 8
