Landsat Collections: Providing a Stable Environmental Record for Time Series Analysis
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 Earth once every 16 days.
The satellite orbits are offset to allow 8-day repeat coverage of any Landsat scene area on the globe. Between the two satellites, approximately 1,500 scenes are added to the USGS archive each day.
Traveling on the descending (daytime) node from north to south, the satellites cross the equator on each pass at a time that provides the maximum illumination with minimum water vapor (haze and cloud build-up). Landsat 8 and Landsat 9 cross the equator at 10:00 a.m. +/- 15 minutes (mean local time) in their respective orbits
The Landsat 8 and Landsat 9 satellites each acquire data in accordance with their respective Long Term Acquisition Plan (LTAP) using parameters such as seasonality, land definition, historical cloud cover, gain settings, and sun angle.

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...
How can I find the acquisition time for a Landsat scene?
Landsat descending (daytime) acquisitions run from north to south; they cross the equator between 10:00 am and 10:25 am local time on each pass to provide maximum illumination. The acquisition start and stop times for each scene are listed in the metadata file that is included in the Landsat Level-1 product, and are also displayed on EarthExplorer and GloVis. Landsat data acquisition times are...
How do I search for and download ascending (nighttime) Landsat scenes?
Ascending (nighttime) WRS-2 Path/Row numbers are different from descending (daytime) Path/Rows. Cloud cover values for Landsat night scenes will always be zero. If you know the daytime path/row or coordinates and want to know the nighttime path/row, use the WRS-2 Path/Row to Latitude/Longitude Converter. Use EarthExplorer to search using path/row or coordinates: Access EarthExplorer. On the Search...
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...
How does data from Sentinel-2A’s MultiSpectral Instrument compare to Landsat data?
The Sentinel-2A MultiSpectral Instrument (MSI) data has spectral bands very similar to Landsat 8 and 9 (excluding the thermal bands of Thermal Infrared Sensor (TIRS)). All Sentinel-2 data are freely available from the Copernicus Open Access Hub; therefore, users are encouraged to download the data via https://scihub.copernicus.eu/. To learn more about Sentinel data access information please visit...
What are the band designations for the Landsat satellites?
The sensors onboard each of the Landsat satellites were designed to acquire data in different wavelengths in the electromagnetic spectrum. View Bandpass Wavelengths for all Landsat Sensors The Multispectral Scanner (MSS) carried on Landsat 1,2,3,4 and 5 collected data in four ranges (bands); the Thematic Mapper (TM) sensor on Landsat 4 and Landsat 5 included those bands found on earlier satellites...
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.

Landsat Analysis Ready Data (ARD)
The U.S. Geological Survey (USGS) has improved Landsat data quality and usability through the creation of Analysis Ready Data (ARD) for the conterminous United States, Alaska, and Hawaii. Landsat ARD greatly reduces the preparatory work currently required to do time-series analysis for understanding landscape change for operational and science users.

This is the third video in a series describing the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors.

Landsat 7 Path 38 Row 31, Acquired March 29, 2013
On March 29-30, 2013, the Landsat Data Continuity Mission (later named Landsat 8) was in position under the Landsat 7 satellite. This provided opportunities for near-coincident data collection from both satellites.
