What sensors does the Landsat 9 satellite carry?
Landsat 9 carries the same instruments that are on the Landsat 8 satellite but with some improvements: Operational Land Imager (OLI) for reflective band data. Thermal Infrared Sensor (TIRS) for the thermal infrared bands. OLI has a slightly improved signal-to-noise ratio over Landsat 8's OLI. Landsat 9’s TIRS is a Class-B instrument with a five-year design life and a key improvement of stray light...
What is the Landsat satellite program and why is it important?
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. On July 23, 1972, in cooperation with NASA, the Earth Resources Technology Satellite (ERTS-1) was launched. It was later renamed Landsat 1. Additional Landsat satellites have launched to bring the world an archive of remote sensing data. Currently orbiting and active...
Are there any restrictions on the use or redistribution of Landsat data?
There are no restrictions on Landsat data downloaded from the USGS; it can be used or redistributed as desired. We do request that you include a statement of the data source when citing, copying, or reprinting USGS Landsat data or images. Details are on the EROS Data Citation page.

Can Landsat satellite acquisition requests be made for a specific date and location?
The Landsat 8 and Landsat 9 satellites together acquire approximately 1,500 scenes daily. These scenes are available for download within 6 hours of acquisition. Landsat satellite acquisitions are managed as a system, known as a satellite constellation. Long-Term Acquisition Plans (LTAPs) direct and optimize the daily acquisitions of each active Landsat satellite. Special requests for future...
What are the acquisition schedules for the Landsat satellites?
The Landsat 8 and Landsat 9 satellites orbit the Earth at an altitude of 705 kilometers (438 miles) in a 185-kilometer (115-mile) swath, moving from north to south over the sunlit side of the Earth in a sun synchronous orbit, following the Worldwide Reference System (WRS-2). Each satellite makes a complete orbit every 99 minutes, completes about 14 full orbits each day, and crosses every point on...
How do I search for and download Landsat data?
Landsat data products held in the USGS archives can be searched and downloaded at no charge from a variety of sources. Visit Landsat Data Access for information about how Landsat data products can be downloaded individually or in bulk. Landsat imagery not found in the USGS archive might have been collected by one of the USGS International Cooperator ground stations, each of which are the primary...
After a Landsat scene is collected, when will it become available for search and download?
Landsat scenes become available through EarthExplorer within 6 hours after acquisition and become visible in GloVis within 24 hours. See Landsat Acquisitions for acquisition calendars and information about daily schedules.
