Inside Building 7525, a processing facility at Vandenberg Space Force Base in California, workers assist as the aft stub adapter is lowered onto the interstage adapter for the United Launch Alliance Atlas V rocket on Nov. 4, 2020. The Atlas V will launch NASA’s Landsat 9 satellite from Vandenberg in September 2021. The launch is being managed by NASA’s Launch Services Program based at Kennedy Space Center. Landsat 9 will continue the nearly 50-year legacy of previous Landsat missions. It will monitor key natural and economic resources from orbit. Landsat 9 is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland. It will carry two instruments: the Operational Land Imager 2, which collects images of Earth’s landscapes in visible, near infrared and shortwave infrared light, and the Thermal Infrared Sensor 2, which measures the temperature of land surfaces. Like its predecessors, Landsat 9 is a joint mission between NASA and the U.S. Geological Survey.
