The Space Shuttle, modernized

A program to update the cockpit avionics of NASA's four space shuttles is briefly reviewed. The Space Shuttle Atlantis is the first orbiter to receive new upgrades, which have been installed and are currently being tested in anticipation of a scheduled December 1999 launch to deliver the third stage equipment for the International Space Station. The other three orbiters will be upgraded during regularly scheduled maintenance periods during the next two years. The key element of the upgrade is Honeywell's multifunctional electronic display system (MEDS) which features the first space-qualified flat-panel multifunctional LCD displays. The upgrade program includes a host of other improvements to enhance safety and reduce workload. (AIAA)
