Landsat
The landsat satellite are the one collecting the data from earth's surface. This is an example for landsat word in sentence.
The Landsat program was initiated in the United States in 1972. The first Landsat satellite, Landsat 1, was launched on July 23, 1972, marking the beginning of the series of Earth-observing satellites.
Landsat imagery is free. It is paid for by American tax dollars.
The Landsat program is a series of Earth-observing satellites jointly managed by NASA and the U.S. Geological Survey. It provides valuable data for monitoring changes to the Earth's land surface over time, including deforestation, urban development, and natural disasters. The program has been instrumental in supporting scientific research, resource management, and environmental monitoring.

Landsat-7,can acquire detiled images by detecting light reflected off landforms on Earth.
The Landsat collects information about the surface and forms it into computer data for scientists to study.
The main parts of a Landsat satellite include the payload, which consists of the sensors and cameras for collecting data; the power system, which typically includes solar panels and batteries for energy; the communication system for transmitting data back to Earth; and the spacecraft bus, which provides the structure and support for the satellite's operations.

A Landsat scene is a digital image of the earth as seen by one or another of the radiometers in the Landsat satellite in orbit.Each radiometer is sensitive to a different band of light (the most recent Landsat has 7 radiometers giving 7 bands).The scenes from the red, green, and blue radiometers can be overlayed to give a true-color image.The scenes from the various infrared radiometers can be substituted to give a false-color image, which can show useful information that is difficult to see in the true-color image.
