Landsat 9: The Pieces Come Together
Landsat 9's two science instruments are now attached to the spacecraft, bringing the mission one step closer to launch. In late December, the Operational Land Imager 2 (OLI-2) and the Thermal Infrared Sensor 2 (TIRS-2) were both mechanically integrated on to the spacecraft bus at Northrop Grumman in Gilbert, Arizona.
The Landsat 9 mission continues the nearly 50-year Landsat data record, providing actionable information to resource managers and policymakers around the world. Landsat 9 will record the condition of Earth's ever-changing land surface, enabling scientists and others to monitor crops and algal blooms, to assess deforestation trends and urban growth, and to aid disaster management.
Landsat is a collaboration between NASA and the U.S. Geological Survey. NASA oversees the design, build, and launch; USGS operates the satellites on orbit, and manages the expanding data archive.
