Landsat 9 Satellite

Landsat 9 Satellite launched 27 September on the year 2021, from Vandenberg Air/ Space Force Base, California on an Atlas-V 401 Rocket from United Launch Alliance. It was developed as a collaboration between NASA and the U.S. Geological Survey (USGS).

The satellite will continue to provide consistent and impartial data about the changing land cover and land use of our planet, and enable enhanced studies of the footprint of the growing population
