Space Shuttle orbiter Atlantis has arrived back at the Kennedy Space Center, Florida, after its 10-month upgrade at Boeing in Palmdale, California. The main features of the upgrade include the $9 million Multifunction Electrical Display Subsystem "glass cockpit" and a global positioning satellite-based navigation system. The Atlantis, which is the first orbiter to undergo these upgrades, will be used primarily for International Space Station (ISS) assembly missions.
