Honeywell to deliver final Space Station computers

Designers at Honeywell Space in Phoenix are set to deliver their 51st and final flight multiplexer/demultiplexer (MDM) units for the International Space Station. Company officials shipped their 49th MDM in January. These modular computer units will control core Space Station systems such as power, environmental control, guidance, and navigation, as well as sensors and effectors. They also will manage payload operations and handle the station`s most important commands from ground controllers. Honeywell designers, who developed the MDM under a $240 million contract from Boeing, are developing MDM spares, MDM flight equivalents, and prototype MDM Application Test Environment units. - J.K.
