Within days of the launch, Landsat 1 acquired an image of an astounding 81,000-acre (327.8 square kilometers) fire burning in isolated, central Alaska. For the first time ever, scientists and resource management officials were able to see the full extent of damage from a fire in a single image while it was still burning.

Dallas-Fort Worth, Texas, slid into Landsat 1's view on July 25, 1972. In this false-color image, shades of red indicate vegetated land and grays and whites are urban or rocky surfaces. The composite image is shown using the near-infrared, red and green bands (bands 7, 5, 4) at a 60 meter resolution.

The very first image in the Landsat archive is the MSS image above, showing the Dallas - Fort Worth area of Texas on July 25, 1972. The resolution is 60 meters per pixel in this false-color image, where shades of red indicate vegetated land and grays and whites are urban or rocky surfaces.
