Landsat Next: A Quantum Leap in Earth Observation
Three satellites. Twenty-six spectral bands. Unprecedented resolution. The future of Earth monitoring begins in 2030.
Mission Overview
Landsat Next represents the most ambitious evolution in the 50+ year history of the Landsat program. Scheduled for launch in late 2030/early 2031, this revolutionary mission will deploy a constellation of three identical satellites, each equipped with cutting-edge instruments capable of observing Earth in 26 different wavelengths of light and thermal energy.
This next-generation system will provide more than double the spectral information of current Landsat satellites, with enhanced spatial and temporal resolution that will transform our ability to monitor critical Earth systems, from water quality and agricultural health to climate change impacts and natural disasters.

Revolutionary Capabilities
🛰️ Three-Satellite Constellation
Unlike previous single-satellite missions, Landsat Next will operate as a coordinated constellation of three spacecraft. This configuration will provide coverage of the same area every six days at the equator—nearly three times faster than the current 16-day cycle.
This enhanced temporal resolution is critical for monitoring rapidly changing phenomena such as flood events, agricultural crop development, and wildfire progression.
📊 26 Spectral Bands
Landsat Next will measure 26 distinct spectral bands across visible, near-infrared, shortwave infrared, and thermal infrared regions—more than double the 11 bands of Landsat 8 and 9.
These additional bands enable new applications in water quality monitoring, vegetation stress detection, soil composition analysis, and atmospheric studies.
🔍 Enhanced Spatial Resolution
Most Landsat Next bands will feature 10-20 meter resolution—a significant improvement over the current 30-meter standard. This finer detail enables identification of smaller features and more precise mapping of land cover changes.
The enhanced resolution is particularly valuable for urban planning, precision agriculture, and coastal zone management.
🌡️ Five Thermal Bands
Expanding from two thermal infrared bands to five, Landsat Next will provide dramatically improved surface temperature measurements and material emissivity characterization.
This capability is crucial for drought monitoring, urban heat island studies, wildfire detection, and volcanic activity monitoring.
💧 Advanced Water Quality Monitoring
New spectral bands in the visible spectrum are specifically designed for monitoring water quality parameters including chlorophyll concentration, turbidity, and harmful algal blooms.
These capabilities support freshwater resource management, coastal ecosystem monitoring, and aquatic health assessment.
🌾 Vegetation Health Analysis
Additional near-infrared and red edge bands enable detailed assessment of vegetation health, crop stress, and photosynthetic activity.
These measurements support precision agriculture, forest health monitoring, and ecosystem productivity studies.
Landsat Next Instrument Suite (LandIS)
Advanced Multispectral Imaging System
The Landsat Next Instrument Suite (LandIS) represents a major advancement in satellite remote sensing technology. In 2024, NASA awarded Raytheon Company a $506.7 million contract to develop and build this revolutionary instrument.

New Spectral Capabilities
Enhanced Visible Bands for Water Quality
Landsat Next will include additional bands in the visible spectrum optimized for penetrating water and detecting subtle changes in water composition. These bands enable:
- Detailed mapping of submerged aquatic vegetation
- Detection of harmful algal blooms at early stages
- Measurement of water clarity and turbidity
- Assessment of coral reef health in shallow waters
- Monitoring of coastal water quality and sediment transport
Red Edge and NIR Bands for Vegetation
The "red edge" region (680-750 nm) is particularly sensitive to vegetation health and stress. Landsat Next's red edge bands will enable:
- Early detection of crop disease and pest infestations
- Assessment of plant nitrogen content
- Differentiation between plant species and functional types
- Monitoring of forest canopy closure and leaf area index
- Detection of subtle changes in photosynthetic efficiency
Shortwave Infrared Bands
Additional shortwave infrared (SWIR) bands provide enhanced capabilities for:
- Vegetation moisture content assessment for drought monitoring
- Snow and ice characterization including grain size and liquid water content
- Mineral identification for geological mapping
- Differentiation between clouds, snow, and ice
- Soil moisture and composition analysis
Enhanced Thermal Infrared Capabilities
Five thermal bands (compared to two on Landsat 8/9) will dramatically improve:
- Land surface temperature accuracy and spatial detail
- Material emissivity determination for surface composition
- Evapotranspiration modeling for water resource management
- Urban heat island mapping and mitigation planning
- Wildfire detection, monitoring, and burn severity assessment
- Volcanic thermal anomaly detection
