Company s Five-Segment Boosters will Help Provide Initial Thrust for
First Two Minutes of Flight for SLS
Full Booster Certification Set to Complete Later this Year
DULLES, Va.Sep. 6, 2017--
Orbital ATK (NYSE: OA), a global leader in aerospace and defense
technologies, recently completed an important qualification test of the
avionics system for the solid rocket boosters the company has developed
and is now manufacturing for NASA s Space Launch System (SLS).
Completion of this milestone is an important step toward preparing the
SLS and Orion spacecraft for their first flight in 2019. Two Orbital
ATK-developed five-segment rocket boosters will be used on each SLS
launch to help provide initial thrust for the first two minutes of
The avionics system is considered the brains of the booster as it
starts booster ignition, communicates with the SLS launch vehicle
computers during flight, and initiates booster separation upon
completion of the first stage burn. The system is now qualified as
meeting NASA s demanding human-rating requirements, which provide a
level of redundancy to ensure a safe flight environment through various
phases of lift-off, ascent and staging.
Completion of booster avionics system qualification is a significant
step forward in supporting overall vehicle qualification and launch of
the first flight of SLS Exploration Mission-1, said Jeff Foote, Vice
President of NASA Programs for Orbital ATK s Propulsion Systems
Division. We are proud of this accomplishment and look forward to
completing full certification of the booster later this year.
Qualification of the booster avionics system included a rigorous and
comprehensive test series that thoroughly verified the fidelity of the
system in a variety of expected and abnormal conditions. Key
interactions confirmed during qualification testing included the ability
to initiate booster ignition, control the booster during flight, and
The Space Launch System is NASA s new heavy-lift launch vehicle that is
being built to take crew and cargo to destinations beyond earth orbit,
including to cislunar space and eventually Mars. SLS, along with the
Orion spacecraft, will enable human exploration on a variety of missions
to deep space. It has the greatest capacity of any launch system ever
built, ensuring continued American leadership in space exploration.
Orbital ATK manufactures the twin, five-segment solid rocket boosters in
Promontory, Utah, about an hour and a half north of Salt Lake City.
Contributing to SLS booster production are 29 key suppliers across 17
states including Alabama, Arizona, California, Connecticut, Florida,
Indiana, Kentucky, Massachusetts, Minnesota, New Jersey, New York, North
Carolina, Ohio, Pennsylvania, Texas, Utah and Wisconsin.
