Nasa Landsat Earth observation satellites

NASA Landsat is a series of Earth observation satellites operated by the National Aeronautics and Space Administration (NASA). The first Landsat satellite, Landsat 1, was launched in 1972.

The Landsat satellites are equipped with multispectral scanners and cameras that capture images of the Earth's surface. These images are used for various applications, including monitoring changes in land cover, mapping deforestation, tracking urban growth, and assessing the health of agricultural crops.

The most recent satellite in the series, Landsat 9, was launched on September 27, 2021. It is equipped with advanced sensors that provide higher quality and more accurate images than previous Landsat satellites.

The data collected by Landsat satellites is freely available to the public, allowing scientists, researchers, and other users to study and analyze changes in the Earth's environment over time. This data is also used for disaster response, resource management, and climate change research.

Landsat satellites have been instrumental in monitoring changes in the Earth's surface over the past several decades, providing valuable information for understanding and managing our planet's resources and environment.
