Since 1972, Landsat data have provided a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global-change research.
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth.It is a joint NASA/USGS program.
It takes hundreds of people to design, build, launch, and operate a robust satellite observatory that can withstand the rigors of space and provide reliable, well-calibrated scientific data. Landsat satellites have been operating since 1972, providing a continuous global record of the Earth’s land surface. Design changes to the TIRS-2 are intended to address the Landsat 9 has a contracted launch date of no later than June 2021, Mission Segments Landsat 9 is composed of three mission segments: the space segment (spacecraft and instruments), the launch segment, and the ground segment. As with all satellite imagery, such advancements would have military applications such as through detecting hidden structures or vehicles, which may be detrimental to national interests (I am hugely appreciative for the availability of Landsat data, which has truly been a ground-breaking evolution enabling stepwise changes in our understanding of the environment. U.S. Geological Survey, 2019, Landsat 9 (ver. Landsat 9 Project Update (Sauer) The development and performance of the Operational Land Imager-2 and Thermal Infrared Sensor-2 instruments on Landsat 9 continue to be excellent. As government departments or heavily dependent upon public financing, space agencies have been fearful of encroaching on the territory of the private sector. (Source: USGS/NASA)Improved spectral resolution (both in terms of number of bands and bandwidth sensitivity) is particularly important for land cover differentiation. Grateful for free Landsat to study how large regions change over multiple decades! Landsat 9 will increase the volume of the USGS archive by imaging all global landmasses and nearshore coastal regions, including islands at solar elevation angles greater than 5 degrees that were not always routinely collected prior to Landsat 8.All Landsat 9 data products will continue to be made available for download through the USGS Earth Resources Observation and Science (EROS) Center at no charge.The Landsat study is a project initiated by the U.S. Geological Survey’s Land Remote Sensing Program, the USGS Fort Collins Science Center’s Social and Economic Analysis (SEA) Branch is conducting a study to investigate the users, uses, and benefits of Landsat imagery. *Landsat MSS = the numbers shown are for Landsat 4 and Landsat 5; Landsat 1-3 band numbers are 4, 5, 6 and 7.Landsat 9 Ground System development team members executed the first of a series of Ground Readiness Tests (GRTs) this week as they successfully simulated the communication of command and telemetry data between the Ground Network Element (GNE) at EROS and the Tim Rykowski has a history of reviewing satellite ground systems. For those with a finer focus (e.g. 1.2, April 2020): U.S. Geological Survey Fact Sheet 2015–3081, 4 p., https://doi.org/10.3133/fs20153081. Landsat 9 will image the Earth every 16 days in an 8-day offset with Landsat 8. The Landsat 9 project entered the implementation phase in December 2017 and formally established its cost and schedule baselines.
