We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

With Landsat 7, the Landsat program took another step forward in technological evolution. The first Landsat to have an onboard data recorder, Landsat 7’s improved sensor included a panchromatic band with 15-meter spatial resolution. Three years after launch, a hardware component failure left wedge-shaped spaces of missing data in the imagery. The sensor still acquired more than three-fourths of the data for each scene, and the remaining pixels are extremely accurate.
The satellite acquired science data until January 19, 2024, and the Landsat 7 Mission was decommissioned on June 4, 2025.
