Boeing has delivered NASA three flight computer software test beds,the first critical element for flight software development insupport of NASA's Space Launch System (SLS). Flight softwarecontrols the launch vehicle during preflight tanking operations andin flight. The test beds were delivered on April 25, ahead of schedule, to theSoftware Development Facility at NASA's Marshall Space FlightCenter in Huntsville. They are now being integrated with NASA'sapplication software. "These are the most capable flight computers ever developed forhuman spaceflight," said Dane Richardson, manager for the BoeingSLS Avionics and Software Team. "They have the highest processing capability available in a flightcomputer and triple modular redundant processors. The technology isproven from years of satellite applications, and it's reliableenough to take SLS beyond Earth's orbit." In triple modular redundant processing, three processors withineach flight computer interpret the data, then "vote" to be surethey all agree on the response before sending that solution fromthe computer. The three flight computers on the vehicle thencompare those answers and send commands to the vehicle forexecution. "The triple redundant processors make each computer reliable in theharsh radiation environment. Similarly, the three computers workingin concert make the vehicle reliable," explained Richardson. "Theconfiguration is called the flight computer operating group." "Delivering NASA the flight computer software test beds early givesthem more time to develop the most capable flight software forSLS," said Jim Chilton, vice president for Boeing ExplorationLaunch Systems and SLS program manager. "The Boeing SLS avionics team will continue to work closely withNASA to ensure seamless integration of NASA software and the Boeinghardware and operating system as we move forward in rocket designand development." In 2011, NASA executed a contract modification that changedexisting Upper Stage Production and Instrument Unit Avionicscontracts into a single contract for design, development andproduction of the cryogenic stages and avionics for SLS. SLS will provide an entirely new capability for human explorationbeyond Earth orbit. With its ability to conduct both crew and cargomissions, it also will back up commercial and international-partnertransportation services to the International Space Station. Under NASA's phased development plan for SLS, Boeing is designingthe two cryogenic stages concurrently to maximize the affordabilityof rocket development and operations. The initial flight-test configuration, scheduled to fly in 2017,will provide a 70-metric ton capacity using only the first stage.The complete two-stage vehicle configuration will provide a liftcapability of more than 130 metric tons to enable missions beyondEarth orbit and support deep space exploration.
