Earth Observing-1 Satellite Far Exceeds Design and Mission Life
Significant Milestone Highlights Orbital ATK s Superior Record of
Reliability and Performance on Earth Science Satellite Programs
DULLES, Va.Mar. 30, 2017--
Orbital ATK (NYSE: OA), a global leader in aerospace and defense
technologies, today announced it successfully concluded 17 years of
mission support for NASA s Earth Observing-1 (EO-1) satellite. The
spacecraft, built by Orbital ATK for NASA s Goddard Space Flight Center
in Greenbelt, Maryland, was decommissioned under NASA s direction on
March 30, 2017.

The EO-1 satellite, launched on November 21, 2000, had an initial design
and mission life of one year, but continued successful operations for
more than 16 years beyond the initial mission. Orbital ATK served as the
mission s prime contractor, satellite mission integrator and bus
developer. The EO-1 mission developed and validated a number of
instrument and spacecraft bus breakthrough technologies designed to
enable the development of future earth imaging observatories.
We are proud to mark this historic occasion with our NASA partners and
celebrate EO-1 s incredible 17 year journey, said Frank Culbertson,
President of Orbital ATK s Space Systems Group. Serving as one of
NASA s pathfinder Earth satellites, EO-1 delivered thousands of high
quality images providing valuable data for the science community that
included scenes from the World Trade Center attacks, flooding in New
Orleans after Hurricane Katrina and volcanic eruptions. All of these
results validate the cutting edge satellite and instrument technologies
that performed flawlessly and exceeded mission expectations.
EO-1, using two major observing instruments, Advanced Land Imager (ALI)
and the Hyperion imaging spectrometer, has provided over 92,000 images
to date consisting of equal amounts of multispectral and hyperspectral
imagery. These instruments allowed the EO-1 team to acquire high spatial
resolution of events and natural disasters around the world. The
Hyperion instrument also allowed scientists to see chemical constituents
of Earth s surface in fine detail with hundreds of wavelengths.
EO-1 s science data and research has also been noted in well over 1,500
related publications further demonstrating the satellite s impact on
Earth science and technology advancements. Seven other technologies
developed under the NASA New Millennium Program during the last 1990s
were also validated during the first year of EO-1 mission operations.
Under NASA s decommissioning process, the mission team will shut down
the satellite effective March 30, 2017, and confirm that the
spacecraft s final configuration is consistent with the approved End of
Mission plan. NASA estimates the spacecraft will safely reenter the
Earth s atmosphere in 2056.
As the EO-1 mission concludes, Orbital ATK continues its work as one of
the industry s leading providers of Earth science satellites. Dating
back more than thirty years, the company s satellite fleet past, present
and future conduct measurements and collect high quality imagery to help
scientists study Earth to unlock the mysteries of natural disasters and
improve weather forecasts. Current earth science programs in process at
Orbital ATK manufacturing facilities include Joint Polar Satellite
System-2 (JPSS-2); Landsat-9; Ice, Cloud and Land Elevation Satellite-2
(ICESat-2); Transiting Exoplanet Survey Satellite (TESS); and
Ionospheric Connection Explorer (ICON).
