NASA launched its powerful new Landsat 9 Earth-observing satellite into orbit on Sept. 27, 2021, on a mission to monitor our planet's land resources.
The mission rode to orbit on a United Launch Alliance Atlas V rocket, lifting off from Space Launch Complex 3 at Vandenberg Space Force Base in California. See photos of the launch and mission preparations in this Space.com gallery!

Together with its sister satellite Landsat 8, which launched in 2013, Landsat 9 will image all of Earth's land and coastal areas to provide a complete picture of the planet every eight days. Designed and built by NASA, Landsat 9 is operated by the United States Geological Survey (USGS), and data from the mission will be publicly available on the USGS website.
Inside the Vertical Integration Facility at Vandenberg Space Force Base in California, technicians work to attach the Landsat 9 spacecraft to the evolved expendable vehicle secondary payload adapter (ESPA), on Aug. 11, 2021.
The ESPA connects Landsat 9 to the payload adapter so that it can be attached to the second stage of the Atlas V rocket.
Landsat 9 is secured inside its payload fairing at the Integrated Processing Facility at Vandenberg Space Force Base in California, ahead of its planned September 2021 launch into orbit on a United Launch Alliance Atlas V rocket. The payload fairing, or "nose cone," helps to protect the spacecraft during the launch.
