''Interior Department Secretary Deb Haaland says the program provides "a rich form of data" that helps people in their everyday lives and is vital in dealing with climate change.''

''The U.S. Interior Department, the U.S. Geological Survey, NASA with the Congressional Science and Technology Committee (originally the [https://science.house.gov/about/history-and-jurisdiction Science and Astronautics Committee] were responsible for building the original Landsat program (which overcame much opposition within the military). [https://landsat.gsfc.nasa.gov/about/history ERTS-1, the Earth Resources Technology Satellite], as the original Landsat satellite was officially first called, was 'greenlighted' to go as a real time earth observation mission in 1970. The vast digital database it gathered has proven over the years the wisdom of the visionaries who first proposed, drafted legislation creating, funding, then engineering, testing, launching and ably defending the Landsat mission from critics over the decades. Now the results are being re-considered for the unique value they provide in guiding policy discussion, debate and decisions. The Landsat library of imagery, millions of images, multispectrum observations of change on earth over the first fifty years of the mission's existence, are seen in a new light.''

''"We're in the thick of the climate crisis right now, we see that every day — drought, wildfires, hurricanes, Hurricane Ida that devastated parts of the South and went all the way up to New England," the current Interior Department head, Ms Haaland, the first Native American to hold the post said.''

''"Images like the ones that Landsat 9 will bring back to us will help to guide us in how we are approaching climate change, working to make sure that we can make the best decisions possible, so that folks have water into the future, that we can grow our food into the future."''

''The Landsat Program has provided decades of calibrated high spatial resolution data of the Earth's surface to a broad and varied user community, including agribusiness, global change researchers, academia, state and local governments, commercial users, national security agencies, the international community, decision makers, and the general public. Landsat images provide information meeting the broad and diverse needs of business, science, education, government, and national security.''

''The mission of the Landsat Program is to provide repetitive acquisition of moderate-resolution multispectral data of the Earth's surface on a global basis. Landsat represents the '''only source of global, calibrated, moderate spatial resolution measurements of the Earth's surface that are preserved in a national archive and freely available to the public. The data from the Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space. It is a record unmatched in quality, detail, coverage, and value.'''


''The Landsat 8 observatory offers these features'':

''Data Continuity: Landsat 8 is the latest in a continuous series of land remote sensing satellites that began in 1972.''

''Global Survey Mission: Landsat 8 data systematically builds and periodically refreshes a global archive of sun-lit, substantially cloud-free images of the Earth's landmass.''

''Free Standard Data Products: Landsat 8 data products are available through the USGS EROS Center at no charge.''

* ''See #IC, International Collaborators -- http://landsat.usgs.gov/BenefitsofBecominganIC.php''

''Radiometric and Geometric Calibration: Data from the two sensors, the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS), are calibrated to better than 5% uncertainty in terms of top-of-atmosphere reflectance or absolute spectral radiance, and having an absolute geodetic accuracy better than 65 meters circular error at 90% confidence (CE 90).''

''Responsive Delivery: Automated request processing systems provide products electronically within 48 hours of order (nominally much faster).''

''The continuation of the Landsat Program is an integral component of the U.S. Global Change Research Program and will be used to address a number of science priorities, such as land cover change and land use dynamics. Landsat 8 is part of a global research program known as NASA’s Science Mission Directorate, a long-term program that is studying changes in Earth's global environment. In the Landsat Program tradition, Landsat 8 continues to provide critical information to those who characterize, monitor, manage, explore, and observe the land surfaces of Earth over time.''

''The U.S. Geological Survey has a long history as a national leader in land cover and land use mapping and monitoring. Landsat data, including Landsat 8 and archive holdings, are essential for USGS efforts to document the rates and causes of land cover and land use change, and to address the linkages between land cover and use dynamics on water quality and quantity, biodiversity, energy development, and many other environmental topics. In addition, the USGS is working toward the provision of long-term environmental records that describe ecosystem disturbances and conditions...''

''EarthSky, a radio program that brings current science ideas, strategies, and research results to people worldwide, has announced the selection of '''Dr. Gavin A. Schmidt''' as the 2011 EarthSky Science Communicator of the Year. Schmidt was voted for this honor overwhelmingly by EarthSky’s Global Science Advisor committee made up of over a thousand participants.''

''Schmidt works on [https://www.greenpolicy360.net/w/Earth_and_Space,_Politics climate modeling at NASA’s Goddard Institute for Space Studies (GISS)] in New York. He coauthored '''Climate Change: Picturing the Science''' in 2009. In his recent EarthSky interview, Schmidt talked about the importance of describing science as a work in progress, an ongoing process. He is convinced that sharing scientists’ stories with the public—the details of how and why they conduct their research—is as important as the results that make the news. Schmidt considers science “one of the greatest, most successful human endeavors that we’ve ever embarked upon.” While looking at graphs and equations can be an esoteric endeavor, people generally have a visceral response to images of changes in the landscape and of scientist at work.''

'''Measuring the Ocean's Depths, Landsat pioneers ocean science with Jacques Cousteau'''


* https://blogs.nasa.gov/earthexpeditions/tag/landsat/


''To establish if Landsat could accurately measure ocean depth from space, simultaneous measurements from ships, divers and the satellite were needed.''

''Schweickart knew a coordinated bathymetry expedition was an essential step. He had honed his diving expertise while training for his Skylab mission in NASA’s water immersion facility and was enthusiastic about scuba work. Teaming with Cousteau was a natural fit.''

''An elaborate experiment was designed to determine definitively if multispectral data from the Landsat satellites could be used to calculate water depth. The clear waters of the Bahamas and coastal Florida were selected as the test site.''

''The experiment design involved two research vessels, the Calypso and Johns Hopkins University Applied Physics Lab’s Beadonyan, being in position, or “on station,” when the Landsat 1 and 2 satellites went overhead on eight different days (four consecutive days on each of two weeks).''

''The overall concept was simple: the research ships would use their fathometers to measure water depth at the exact same time that the satellite flew overhead and then those measurements would be compared (the simultaneous measurements eliminated any environmental or atmospheric differences that could have complicated comparisons).''


''Using these measurements, scientists developed mathematical models describing the relationship between the satellite data and water depth, accounting for how far the light could travel through water, and how reflective the ocean floor was.''

''“Particular thanks” was given to Cousteau’s team of divers in the experiment’s final report “for their dedication and expertise in the underwater phases of the experiment, without which, measurements of key experimental parameters could not have been made.”''

''The diving prowess of Cousteau, Delemotte, and the Calypso crew added inextricably to the realm of satellite-derived bathymetry. Because of data collected during the NASA-Cousteau expedition, charts in clear water areas around the world were updated, making sea navigation safer. It was the precision measurements made by Delemotte and Cousteau’s team of divers that made bathymetry calculations for those chart updates possible.''
