Orbital ATK has been given approval to begin building the NASA Landsat 9 spacecraft after completing a comprehensive design review of the mission. Landsat 9, a land surface mapping satellite, will collect space-based images and data that serve as valuable resources for researchers in areas that include agriculture, land use mapping, and disaster relief. Orbital ATK is designing and manufacturing the satellite, integrating two government-furnished instruments, and supporting launch, early orbit operations and on-orbit check-out of the observatory.
