1. Mission Objectives and Applications
- The satellite’s ability to capture multispectral data allows it to monitor diverse surface characteristics such as the health of vegetation, the quality of water, and geological formations.
- Landsat-9 satellite is a part of the collaboration between NASA and the United States Geological Survey (USGS).
2. Technical Specifications
- The satellite is equipped with the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). OLI captures data in visible, near-infrared, and shortwave infrared wavelengths, while TIRS focuses on thermal infrared wavelengths.
- Landsat-9 provides moderate spatial resolution imagery with a ground resolution of 30 meters for most bands, except for the panchromatic band, which images at a spatial resolution of 15 m.
- Landsat-9 operates in a sun-synchronous orbit at an altitude of approximately 705 kilometers (438 miles).
- Landsat-9 was launched on the 27th of September 2021.
- The spacecraft can achieve a 185 km swath width.
3. Observation Frequency
- Landsat-9 and Landsat-8 orbit in a coplanar configuration, positioned 180° apart. This arrangement reduces the revisit time to 8 days.
4. Open Access Data
- Landsat 9 data is publicly available from the United States Geological Survey (USGS).
5. API access
With our API, you can search data, track satellite passes, and more using Landsat-9.
