One Year Design Life Has Stretched to Eight Full Years
The
NASA's Earth Observer-1 (EO-1) has reached its eighth anniversary
on orbit. The EO-1 satellite, launched on November 21, 2000 had an
initial design and mission life of one year, but has continued
successful operations for more than 7 years past the initial
mission.
ATK served as the Prime Contractor, Mission Integrator and Bus
Developer for the EO-1 mission. The Earth Observing-1 (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.
"The on orbit performance of the EO-1 satellite is extraordinary
and a testimony to the capabilities of ATK," stated Carl Marchetto,
President of ATK's Space Systems. "I am proud of ATK's talented and
dedicated engineers and workforce who work toward excellence in
mission and program execution."
EO-1 has performed over 76,000 images to date and has spawned
over 404 related publications. EO-1 is currently being used as part
of a sensor web that allows autonomous observing of earth images.
The EO-1 extended mission supports on-orbit testbed activities for
advanced technology and hyper-spectral research.
Currently, EO-1 is performing more than 90 data collection
events a week. The Spacecraft mission has performed non traditional
earth observation activities such as the monitoring of brush fires,
assessing post hurricane damage and monitoring active volcanic
eruptions using both multi-spectral and hyper-spectral imaging.
