The next leap in Earth observation arrives in 2031
In short: Maintaining a consistent view of our changing planet requires more than just a camera in orbit; it requires a seamless bridge between generations of technology. NASA and the USGS are preparing to launch a successor to the Landsat fleet that promises to significantly sharpen our vision of the world.
The Landsat program is a cornerstone of global land observation, providing data essential for managing water and energy, monitoring forests, and planning urban growth. To ensure these observations remain uninterrupted, NASA and the U.S. Geological Survey (USGS) are launching the Landsat Data Continuity Mission (LDCM) on February 11, following a prelaunch conference at Vandenberg AFB on February 8. This mission is designed specifically to extend the continuity of critical data used in disaster recovery and environmental health monitoring.
Looking further ahead, the Landsat 10 mission, scheduled for launch in 2031, represents a "quantum leap" in measurement capabilities. While it maintains the heritage of previous missions, it introduces the LandIS instrument suite, which will collect 26 spectral bands—an increase of 15 bands over the currently operational Landsat 8 and 9. This suite includes 21 visible to shortwave-infrared (VSWIR) bands and 5 thermal-infrared (TIR) bands, all designed to offer higher spatial resolutions than any prior Landsat mission.
A key technical innovation of Landsat 10 is the near-simultaneous acquisition of all bands. By capturing data at once, the satellite minimizes illumination changes between different spectral layers, allowing researchers to more accurately detect clouds and calculate complex products like evapotranspiration. Furthermore, the mission includes five new bands designed to mirror the European Space Agency’s Copernicus Sentinel-2 mission, facilitating better data fusion. It also features a dedicated water vapor band, which enables atmospheric correction without needing to rely on external satellite data.
