The first data from Landsat 9, of Australia's Kimberley Coast in Western Australia, shows off the capabilities of the two instruments on the spacecraft. This image, from the Operational Land Imager 2, or OLI-2, was acquired on Oct. 31, 2021. Although similar in design to its predecessor Landsat 8, the improvements to Landsat 9 allow it to detect more subtle differences, especially over darker areas like water or the dense mangrove forests along the coast.

Although similar in design to its predecessor Landsat 8, the improvements to Landsat 9 allow it to detect more subtle differences, especially over darker areas like water or the dense mangrove forests along the coast.

Landsat 9, a joint mission from NASA and the U.S. Geological Survey, launched Sept. 27, 2021, and has now collected its first images of Earth. These images, all acquired Oct. 31, 2021, provide a preview of how the mission will help people manage vital natural resources and track the impacts of climate change, adding to Landsat’s unparalleled data record that spans nearly 50 years of space-based Earth observation.

Shown in the images are coastal ecosystems in Australia; the intersection of cities and coastlines in the Florida Panhandle; glaciers in High Mountain Asia; and farm fields surrounding Lake Erie.

Landsat 9 carries two instruments that capture imagery: the Operational Land Imager 2, or OLI-2, which detects nine different wavelengths of visible, near-infrared and shortwave-infrared light; and the Thermal Infrared Sensor 2, or TIRS-2, which detects two wavelengths of thermal radiation to measure slight changes in temperature. These instruments will provide Landsat 9 users essential information about crop health, irrigation use, water quality, wildfire severity, deforestation, glacial retreat, urban expansion and more. OLI-2 was built by Ball Aerospace and TIRS-2 was built by NASA's Goddard Space Flight Center. Northrop Grumman built the Landsat 9 spacecraft, integrated it with the instruments, and tested the observatory.

NASA’s Landsat 9 team is in the midst of a 100-day check-out period, which involves testing the satellite’s different systems and subsystems and calibrating the instruments in preparation for handing the mission over to the USGS in January. The USGS will operate Landsat 9 along with Landsat 8, and together the two satellites will collect approximately 1,500 images of Earth’s surface every day, covering the globe every eight days. Landsat 9 data will be available to the public, for free, from USGS’s website, as soon as the satellite begins normal operations.

Landsat 9 carries two instruments designed to work together to capture a broad range of wavelengths: the Operational Land Imager 2, or OLI-2, which detects nine different wavelengths of visible, near-infrared and shortwave-infrared light; and the Thermal Infrared Sensor 2, or TIRS-2, which detects two wavelengths of thermal radiation to measure slight changes in temperature. Data from both instruments are shown in the two pairs in this image. The top left shows snow and glaciers in the Himalayan mountains, leading to the flat Tibetan Plateau to the north. The top right shows the same area in thermal data from the TIRS-2 instrument. Blue-white color indicates relatively cooler surface temperatures, while orange-red indicates warmer surface temperatures.The bottom left shows the brown and green rectangles of farm fields in southern Ontario, sandwiched between Lake Erie and Lake St. Clair. The white and grey rectangles in the bottom of the image are produce greenhouses, which show up as blue-ish (relatively cooler) spots in the TIRS-2 image on the right.Version without labels

Florida's Emerald Coast -- The white sands of Pensacola Beach stand out in this Landsat 9 image of the Florida Panhandle of the United States, with Panama City visible under some popcorn-like clouds. Landsat and other remote sensing satellites help to track changes to US coastlines, including urban development and potential impacts of rising sea levels. From Oct. 31, 2021, the first day of data collection for Landsat 9.Version without labels

Detroit and Lake Erie -- Sediments swirl in Lake Erie and Lake St. Clair in this Landsat 9 image of both Detroit, Michigan, and Windsor, Ontario, from Oct. 31, 2021. The Great Lakes serve as sources of freshwater, recreational activity, transport, and habitat for the upper-midwestern US, and water quality remains a high priority. In warmer months, Landsat 9 observes swirls of green algae which can become harmful algal blooms. Landsat 9 will be able to help scientists and resource managers identify those blooms early, identifying areas to test further.Version without labels

The Dry Southwest U.S. -- In the Western U.S., in places like the Navajo Nation as seen in this Landsat 9 image, Landsat and other satellite data helps people monitor crop health and help manage irrigation water. With only 85 rain gauges to cover more than 27,000 square miles, satellite data and climate models are filling the gaps to help the Navajo Nation monitor drought severity.Version without labels

The Himalayas -- The city of Kathmandu, Nepal, seen at the bottom left of this Landsat 9 image, lies in a valley south of the Himalayan Mountains between Nepal and China. Glaciers, and the lakes formed by glacial meltwater, are visible in the top middle of this image. In High Mountain Asia, many communities rely on meltwater from glaciers – and Landsat can help track how those glaciers are changing in a warming climate. Previous studies with Landsat have documented shrinkage of Himalayan glaciers, as well as changing lake levels the adjacent Tibetan plateau. From Oct. 31, 2021, the first day of data collection for Landsat 9.Version without labels

Australia's Kimberley Coast -- Mangroves are prominent along the northwest coast of Australia. The first image collected by Landsat 9, on Oct. 31, 2021, shows mangroves clustered in protected inlets and bays on the edge of the Indian Ocean. Fluffy cumulus clouds and high-altitude cirrus clouds hover nearby. The aqua colors of the shallow near-shore waters give way to the deep, dark blues of the ocean.Version without labels
