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.

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.

Landsat 9 is lifted and mated to the United Launch Alliance's Atlas V rocket at Space Launch Complex 3 at Vandenberg Space Force Base in California, on Sept. 15, 2021.

The United Launch Alliance's Atlas V rocket takes to the skies with the Landsat 9 satellite after lifting off from Space Launch Complex 3 at Vandenberg Space Force Base in California, at 2:12 p.m. EDT (11:12 a.m. local time; 1812 GMT) on Sept. 27, 2021.
