Mission Description
Landsat 8 is a joint mission formulated, implemented, and operated by the National Aeronautics and 
Space Administration (NASA) and the Department of Interior (DOI) United States Geological Survey 
(USGS) that builds upon previous Landsat missions. Landsat 8 is a remote sensing satellite mission 
providing coverage of the Earth’s land surfaces, collecting multi-spectral land images, including 
infrared. Landsat 8 continues the more than 40 years of global data collection and distribution of the 
Earth’s continental surfaces by the Landsat series of satellites to support global change research and 
applications. This data constitutes the longest continuous record of the Earth’s surface as seen from 
space. 
Spacecraft
Orbital was responsible for the design and manufacture of the Landsat 8 spacecraft bus, the integration 
of the customer-furnished payload instruments, and full observatory testing, including environmental 
and EMI/EMC. To meet the performance and schedule challenges, a simple, robust design was utilized 
based on Orbital's flight-proven LEOStar-3 standard bus. This ensures that Landsat 8 will continue the 
Landsat heritage, obtaining unique and valuable data and imagery to be used in agriculture, education, 
business, science, and government.
