The three-page document contained one article that explained the rationale for the National Oceanic and Atmospheric Administration (NOAA) forgoing earlier plans to place instruments on NASA\u2019s first EOS polar platform \u2013 at that time envisioned as one of several large platforms operated by NASA, NOAA, Europe, and Japan, with numerous instruments on each platform. Along with this article, that first issue featured an EOS launch schedule, a list of publications and acronyms, and a personals section. Yes; personals. It\u2019s hard to believe that a NASA newsletter would feature personals, but remember that this first issue was published at a time before the internet was widely available. The newsletter served as a bridge to quickly connect hundreds of newly chosen EOS investigators scattered worldwide with the latest EOS program developments. The content of early issues included the latest reports from Investigators Working Group meetings, payload panel reviews, and instrument science team meetings. In short, before the Web, <em>The Earth Observer<\/em> was the thread that kept the various EOS teams connected.<\/p>\n<div id=\"\" class=\"hds-image-carousel grid-container grid-container-block padding-top-4 padding-bottom-4 hds-module alignwide wp-block-nasa-blocks-image-carousel\">\n<div id=\"carousel-wrapper-carousel-695309200e620\" class=\"hds-carousel-wrapper\">\n<div class=\"image-carousel-slider margin-0\" id=\"image-carousel-slider-carousel-695309200e620\" data-client-id=\"carousel-695309200e620\" data-variation=\"carousel\" data-autoplay=\"\" data-autoplay-speed=\"2000\" data-play-pause=\"\" data-transition-type=\"slide\" data-progress=\"\" data-progress-labels=\"\" data-start-label=\"Start\" data-end-label=\"End\" data-labels-initialized=\"true\">\n<div class=\"display-block width-full\" data-label=\"Earth Observer issues March 1989 and November 1989.\">\n<figure class=\"margin-0\">\n<div class=\"hds-cover-wrapper hds-image-carousel-slide margin-bottom-2\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><img loading=\"lazy\" decoding=\"async\" width=\"1440\" height=\"810\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=1440&amp;h=810&amp;fit=clip&amp;crop=faces%2Cfocalpoint\" class=\"attachment-large size-large\" alt=\"Earth Observer Covers 1-2\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" loading=\"lazy\" srcset=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=1440&amp;h=810&amp;fit=crop&amp;crop=faces%2Cfocalpoint 1440w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=300&amp;h=169&amp;fit=crop&amp;crop=faces%2Cfocalpoint 300w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=768&amp;h=432&amp;fit=crop&amp;crop=faces%2Cfocalpoint 768w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=1024&amp;h=576&amp;fit=crop&amp;crop=faces%2Cfocalpoint 1024w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=400&amp;h=225&amp;fit=crop&amp;crop=faces%2Cfocalpoint 400w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=600&amp;h=338&amp;fit=crop&amp;crop=faces%2Cfocalpoint 600w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=900&amp;h=506&amp;fit=crop&amp;crop=faces%2Cfocalpoint 900w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-final-editors-corner\/EC-Issues-1.png?w=1200&amp;h=675&amp;fit=crop&amp;crop=faces%2Cfocalpoint 1200w\" sizes=\"auto, (max-width: 1440px) 100vw, 1440px\"><\/figure><figcaption class=\"hds-caption padding-y-2\">\n<div class=\"hds-date-text p-sm margin-0\">Earth Observer issues March 1989 and November 1989.<\/div>\n<div class=\"hds-caption-text p-sm margin-0\"><strong>Figure 1<\/strong>.

Over the years, as EOS grew from an idea into actual spacecraft and instruments launching and flying in space, the newsletter began chronicling their journey. Early issues of <em>The Earth Observer <\/em>describe \u2013 often in meticulous detail \u2013 the meetings and deliberations during which the EOS concept evolved through various revisions and restructuring before the first EOS mission took flight. In the end, NASA launched three mid-sized \u201cflagship\u201d missions (about the size of a small bus) that became known as <em>Terra<\/em> (1999), <em>Aqua <\/em>(2002), and <em>Aura<\/em> (2004) and complemented their measurement capabilities with numerous other small-to-mid-sized missions. The result is the Earth-observing fleet in orbit above us today. Many of these missions fly in polar, low Earth, or geosynchronous orbit, while several others observe the Earth from the perspective of the International Space Station (ISS) \u2013 see <strong>Figure 2. \u00a0\u00a0<\/strong><\/p>\n<p>EOS missions are known for their longevity; many missions (and their follow-ons) have long outlived their anticipated life cycle. Each of these missions beam back reams of raw data that must be processed and stored so that it can be accessed and used as input to computer models and scientific studies to understand past environmental conditions, place our current situation in the proper context, and make predictions about the future path our planet could follow.<\/p>\n<div id=\"\" class=\"width-full maxw-full margin-left-auto margin-right-auto hds-media-align-inline hds-module wp-block-nasa-blocks-video\">\n<div class=\"hds-cover-wrapper width-full maxw-full flex-column\">\n<div class=\"hds-video-container width-full embed-container\"><video title=\"current_earth_observing_fleet_1080p.mp4\" id=\"nasa-plus-AdOyI\" class=\"video-js video-player vjs-fluid width-full\" data-setup='{\"controls\":true,\"preload\":\"auto\",\"plugins\":{\"mux\":{\"debug\":false,\"data\":{\"env_key\":\"91nns8oppqdfqc44lgo4b1gni\",\"player_name\":\"www.nasa.gov Player\",\"video_name\":\"current_earth_observing_fleet_1080p.mp4\"}}}}'><source src=\"https:\/\/assets.science.nasa.gov\/content\/dam\/science\/cds\/svs\/a030000\/a030400\/a030496\/current_earth_observing_fleet_1080p.mp4\" type=\"video\/mp4\"><p class=\"vjs-no-js\">To view this video please enable JavaScript, and consider upgrading to a web browser that<br \/>\n\t\t\t\t\t<a href=\"https:\/\/videojs.com\/html5-video-support\/\" target=\"_blank\" rel=\"noopener\">supports HTML5 video<\/a><\/p><\/video><\/div>\n<\/div>\n<div class=\"hds-media-caption hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\">\n<div>Figure 2.

Given that publication of this final content marks the end of an era, the newsletter team felt it appropriate to offer some perspective on the newsletter\u2019s contribution. The feature that resulted focuses on the relationship between <em>The Earth Observer<\/em> and EOS \u2013 with specific emphasis on our reporting on satellite missions. See the online article, <em>The Earth Observer<\/em>: Offering Perspectives from Space Through Time, to learn more.<\/p>\n<p>One of the final items published focuses on <a href=\"https:\/\/terra.nasa.gov\/\" rel=\"noopener\">Terra<\/a>, the first EOS flagship, which launched into the night sky on Dec. 18, 1999 from Vandenberg Space Force (then Air Force) Base (VSFB) in California on what was designed as a six-year mission of discovery. Terra\u2019s payload included five instruments \u2013 <a href=\"https:\/\/asterweb.jpl.nasa.gov\/\" rel=\"noopener\">Advanced Spaceborne Thermal Emission and Reflection Radiometer<\/a> (ASTER), <a href=\"https:\/\/ceres.larc.nasa.gov\/\" rel=\"noopener\">Clouds and the Earth\u2019s Radiant Energy System<\/a> (CERES), <a href=\"https:\/\/terra.nasa.gov\/about\/terra-instruments\/mopitt\" rel=\"noopener\">Measurement of Pollution in the Troposphere<\/a> (MOPITT), <a href=\"https:\/\/www.jpl.nasa.gov\/missions\/multi-angle-imaging-spectroradiometer-misr\/\" rel=\"noopener\">Multi-angle Imaging SpectroRadiometer<\/a> (MISR), and <a href=\"https:\/\/modis.gsfc.nasa.gov\/about\/\" rel=\"noopener\">Moderate Resolution Imaging Spectroradiometer<\/a> (MODIS) \u2013 intended to collect data that would fill in gaps in our knowledge of the Earth System (as it stood on the cusp of the 21<sup>st<\/sup> century, when Terra launched) and in particular, about how land interacts with the atmosphere on a regional and continental scale. The mission also focused on measuring key planetary characteristics needed to understand Earth\u2019s changing environment (e.g., albedo, roughness, evaporation rate, and photosynthesis). The goal was to provide a holistic approach to address larger scientific questions. For more than 26 years, Terra has trained her five instruments toward Earth and gathered data to address wildfires, flooding, hurricanes, and polar ice.<\/p>\n<p>As 2020 drew to a close, in order to conserve enough fuel for the end of the mission, NASA Headquarters decided it was time to for Terra to stop conducting the periodic maneuvers to maintain its 10:30 AM equator crossing. After ceasing maneuvers, the satellite began to drift, which Terra (and the other flagships) have done for the past few years. As Terra\u2019s life draws to a close, it continues to ignite the imagination of the next generation of scientists to catapult the study of our planet for generations to come. Refer to the article, Terra: The End of An Era, to learn more about the feat of engineering that has kept the satellite gathering data two decades past the end of its \u201cPrime Mission\u201d and the key scientific achievements that have resulted.<\/p>\n<p>Since 1997, six CERES instruments have been launched on the\u00a0EOS\u00a0and the\u00a0Joint Polar Satellite System (JPSS) platforms, including the <a href=\"https:\/\/gpm.nasa.gov\/missions\/trmm\" rel=\"noopener\">Tropical Rainfall Measuring Mission<\/a> (TRMM), <a href=\"https:\/\/terra.nasa.gov\/\" rel=\"noopener\">\u00a0Terra<\/a> [2], <a href=\"https:\/\/aqua.nasa.gov\/\" rel=\"noopener\">Aqua<\/a> [2], the <a href=\"https:\/\/science.nasa.gov\/mission\/suomi-npp\/\" rel=\"noopener\">Suomi National Polar-orbiting Platform<\/a> (Suomi NPP), and the <a href=\"https:\/\/www.nesdis.noaa.gov\/our-satellites\/currently-flying\/joint-polar-satellite-system\" rel=\"noopener\">Joint Polar Satellite System\u20131<\/a> (JPSS-1, now named NOAA\u201320) mission and used to study <em>Earth\u2019s radiation budget <\/em>(ERB) \u2013 the amount of sunlight absorbed by Earth and the amount of infrared energy emitted back to space \u2013 that has a strong influence on climate. Researchers pair measurements from CERES instruments with information gathered from other sources to clarify ERB. While the latency of CERES data prevents it from being used for weather forecasting directly, the information on ERB can be used to verify the radiation parameterization of computer models used to make weather forecasts and make predictions about future climate conditions. The ERB data can also be applied to other science research and applications that benefit society. As an example, researchers have used this data to accurately detail changes in the movement of energy from Earth \u2013 especially the role that clouds and aerosols play in Earth\u2019s energy budget. The CERES Science Team has a long history of recording proceedings of their meetings in <em>The Earth Observer<\/em>. It is thus appropriate that a CERES STM summary should be among the last items published this newsletter. Read more about the current status of CERES in space in the article, The State of CERES: Updates and Highlights.<\/p>\n<p>NOAA and NASA have partnered in many endeavors together.<em> The Earth Observer <\/em>has reported on these collaborations over the years. One well known example is the two agency\u2019s partnership to develop and launch the <a href=\"https:\/\/science.nasa.gov\/mission\/goes\/\" rel=\"noopener\">Geostationary Operational Environmental Satellites<\/a> (GOES). This mission has become the backbone of short-term forecasts and warnings of severe weather and environmental hazards. The first satellite, GOES-1, launched in 1975; the most recent, GOES-19, launched in 2024. The technology onboard has improved exponentially over the past five decades.

The newest satellite in NASA\u2019s Earth observing fleet measures sea levels with an accuracy of one inch every second, covering 90 percent of the oceans every 10 days. It will also contribute the record of atmospheric temperature and humidity measurements. These data are beneficial in observing movement of surface currents, monitoring the transfer of heat through the oceans and around the planet, and tracking changes in water temperature. Sentinel-6B will carry several instruments on this mission, including a radar altimeter, an advanced microwave radiometer, and a radio occultation antenna. The satellite\u2019s observations will be paired with information from other spacecraft to provide detailed information about Earth\u2019s atmosphere that will contribute high-resolution data for computer models to improve weather forecasting.<\/p>\n<p>Sentinel-6B is another shining example of successful collaboration between NASA and NOAA, along with several European partners \u2013 ESA, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), Centre National d\u2019\u00c9tudes Spatiales (CNES), and the European Commission.\u00a0<\/p>\n<p>Sentinel-6B has publicly released an image showing some of its first observations since launch.
