What is land satellite?
LANDSAT is a series of satellites that photograph the Earth. The Landsat program is the longest running enterprise for acquisition of imagery of Earth from space. The first Landsat satellite was launched in 1972; the most recent, Landsat 7, was launched on April 15, 1999. The millions of images images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance, education and national security. Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days.

What is a Landsat scene?
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.
