Spectral Comparison of Landsat 8-9 and Landsat Next
This illustration shows the spectral bands of the sensors onboard Landsat 8 and Landsat 9, compared to those of Landsat Next.
Landsat Next will be a constellation of three observatories sent into orbit on the same launch vehicle, which will provide an improved temporal revisit for monitoring dynamic land and water surfaces such as vegetation, wildfire burns, reservoirs and waterways, coastal and wetland regions, glaciers, and dynamic ice sheets.
Landsat Next will have 26 bands; this includes refined versions of the 11 Landsat “heritage” bands, five bands with similar spatial and spectral characteristics to the European Space Agency’s Copernicus Sentinel-2 bands to allow easier merging of data products, and ten new spectral bands to support emerging Landsat applications. With these improvements, Landsat Next will collect on average about 20 times more data than its predecessor, Landsat 9, and continue to provide free and open data access for all users.
