Landsat Collection 2 will improve data quality and provide more accurate information for applications using Landsat, including time-series analysis, resulting in more informed decision-making. The Landsat 8 satellite payload consists of two science instruments—the Operational Land Imager (OLI) and the Thermal InfraRed Sensor (TIRS). Consistency in Landsat’s spatial resolution, calibration, and spectral characteristics over four decades allows long-term, consistent comparisons of historical and current data. (Read more), In late May 2020, Landsat 8 data that were acquired after a December 2019 spacecraft safehold event were reprocessed and made available for download as “OLI-only” scenes. Today’s increased rates of global land cover and land use change have profound consequences for weather and climate change, ecosystem function and services, carbon cycling and sequestration, resource management, the national and global economy, human health, and society. Landsat Missions Landsat 1 On July 23, 1972, the Earth Resources Technology Satellite (ERTS-1) was launched into space onboard a Delta 900 rocket from Vandenberg Air Force Base, California. Landsat 9, slated for a Mid-2021 launch, will join Landsat 8 in orbit; the satellite orbits will be 8 days out of phase. Data from the Moon is used to both complement and corroborate the results from the other on-board calibration activities. Landsat 8, launched in 2013, acquired the scene on Saturday, September 19, 2020 over northern Paraguay. + See Sept. 2016 and 2017 and 2019 charts for comparison. The BPFs are being updated to incorporate minor changes made to the Calibration Parameter Files (CPFs), which are used in the generation of BPFs. It will be the eighth satellite in the Landsat series, as Landsat 6 failed to reach orbit. (Read more), Nominations for the 2020 William T. Pecora Award are now being accepted through May 1, 2020. (Read more), The USGS is placing a copy of its consolidated Landsat global data inventory into a commercial cloud in early 2020. The paper describes the spatial and temporal patterns of burned areas across the conterminous U.S., how burned area varies in relation to the number of operational Landsat sensors, and a comparison with other burned area product datasets.

It was the first Earth-observing satellite to be launched with the express intent to study and monitor our planet’s landmasses. Large optics help by mitigating stray light and ensuring focal plane uniformity (i.e. The Landsat 9 observatory is planned to launch from Vandenberg Air Force Base (VAFB). This page will be unavailable from 6:00 pm to 9:00 pm CDT on Thursday, October 29, 2020. Since the Moon has no atmosphere, it is the perfect consistent source of light to measure–like a gray card for calibrating a camera’s exposure. The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth.It is a joint NASA/USGS program. (Read more), Starting Tuesday, January 21, 2020, all Landsat 8 Bias Parameter Files (BPFs) created prior to December 5, 2019 will be removed from the Landsat Bias Parameter Files search page and regenerated in preparation for Landsat Collection 2. Landsat 9, like Landsat 8, will be both radiometrically and geometrically better than earlier generation Landsats. sameness across the field of the tens-of-thousands of detectors which the telescope focuses light on) to avoid skewed measurements. The nominal spacecraft altitude will be 705 km. Landsat Acquisition Tool. Landsat 8 includes evolutionary advances in technology and performance. NASA is in charge of building, launching, and testing the system, while the United States Geological Survey (USGS) will process, archive, and distribute its data. Landsats 1–3 carried the return beam vidicon (RBV), which had three bands, and the multispectral scanner (MSS), which had four visible bands. Landsat 2 followed just 2.5 years later, on Jan. 22, 1975. Landsat 9 is slated for a Mid-2021 launch. Landsat 9, like Landsat 8, will have a higher imaging capacity than past Landsats, allowing more valuable data to be added to the Landsat global land archive. USGS will take over Landsat 9 management for Phase E (mission operations); they will operate the satellite and manage all data downlinking, processing, and delivery aspects.

In late December, the Operational Land Imager 2 (OLI-2) and the Thermal Infrared Sensor 2 (TIRS-2) were both mechanically integrated on to the spacecraft bus at Northrop Grumman in Gilbert, Arizona. (Read more), The USGS has released an on-demand Landsat Provisional Actual Evapotranspiration (ETa) Science Product that will be useful in understanding the spatiotemporal dynamics of water use over land surfaces and for monitoring hydrologic, agricultural, and environmental systems. The Ground System, other than the MOE, is developed by USGS largely through their support service contract. From the Beginning “The Landsat program was created in the United States in the heady scientific and exploratory times associated with taming the atom and going to the Moon,” explains Dr. John Barker.
