The Landsat program is program is a system of satellites that take pictures of the surface of a planet.
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.
Satellites that explored the Earth have been launched since the 1950s, with notable missions such as the Landsat program beginning in 1972. As for robots that explored the Earth, this can refer to various types of autonomous or remotely operated machines used for scientific research in fields like oceanography, geology, and ecology, among others. These robots have been used for decades, with advancements in technology enabling more sophisticated capabilities and applications over time.
Some artificial satellites launched before Cartosat-2A include Sputnik 1 (1957), Explorer 1 (1958), Telstar 1 (1962), and Landsat 1 (1972).
NASA recently launched the Landsat 9 satellite, a collaboration with the U.S. Geological Survey. This satellite will continue the mission of monitoring changes to the Earth's land and coastal regions.
The Gemini Program
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.
NASA, with the cooperation of the US Department of the Interior, initiated this program in 1967.
The landsat satellite are the one collecting the data from earth's surface. This is an example for landsat word in sentence.
Landsat imagery is free. It is paid for by American tax dollars.
Landsat maps are products derived from satellite imagery captured by the Landsat program, which has been monitoring Earth's surface since 1972. These maps provide valuable data for various applications, including land use planning, environmental monitoring, agriculture, and forestry. By capturing images in multiple spectral bands, Landsat maps can reveal detailed information about vegetation, water bodies, urban areas, and changes over time. The data is widely used by researchers, policymakers, and conservationists to analyze and manage natural resources effectively.

Landsat-7,can acquire detiled images by detecting light reflected off landforms on Earth.
It would depend on the type of data needed. Stock data for example can be downloaded from chart oasis. Data on the Landsat program is available from NASA.

Landsat
The power source for a Landsat satellite are four solar panels. Each solar panel was 2.3 meters by 1.5 meters.
