How does the Landsat satellite work?

Landsat satellites capture images of the Earth's surface using a multi-spectral scanner that detects various wavelengths of light, including visible, infrared, and thermal bands. They orbit the Earth in a polar orbit, providing consistent and repetitive coverage of the same areas every 16 days. The data collected is used for various applications, including land use planning, agriculture monitoring, and environmental research. The images are then processed and made available to scientists and the public for analysis and interpretation.
