This map is an updated bedrock topography map for the eastern extent of the Lafayette Bedrock Valley System in Indiana and Ohio which depicts a portion of an ancient river drainage valley. This image is used with the permission of the Indiana Geological and Water Survey and the Ohio Department of Natural Resources, Division of Geological Survey. 

The Operational Land Imager (OLI) onboard Landsat 8 captured this image of Lake Tahoe.

This is a field photo of geologists from the Indiana Geological and Water Survey and Ohio Geological Survey conducting core drilling of glacial sediments. The information gained from this project aided in the development of a bedrock topography map of a buried ancient river bed. 

This is a 20 foot section of a drill core collected by the Indiana Geological and Water Survey (IGWS). IGWS geologists dub these cores "golden spikes" when they are drilled deep enough to reach the underlying bedrock.

The Betsiboka River in Northern Madagascar is seen in this Landsat 9 natural color image from December 7, 2021. Extensive logging has left the land vulnerable, and iron rich soils are washed into the river, coloring it a reddish orange as it flows to the Betsiboka estuary delta.

NASA and the USGS briefed the Landsat Science Team about Landsat 9 at their Fall Meeting held virtually on November 24, 2021.

Deforestation can happen naturally, through infestation of native beetles and extreme weather. However, people can intentionally clear forests for timber and other industries. Difference between the two can be difficult to diagnose.

On Tuesday December 7, 2021, updates were made to all USGS webpages, including the Landsat Missions Web Site (LMWS).

On November 23, 2021, the Landsat Archive added its ten millionth image. The Landsat 7 scene was acquired over the Dead Sea and is shown as a false color image using the short-wave infrared, near infrared and red bands (bands 5,4,3).

These images of an area in south central Queensland, Australia were acquired by the instruments onboard both Landsat 8 and Landsat 9 on November 15, 2021, as Landsat 9 flew beneath Landsat 8 as the satellite continued its climb to nominal orbital altitude.

This graphic displays a few of the common band Red-Green-Blue (RGB) combinations of Landsat data. For more information about using Landsat bands in your research, visit the following pages:

Landsat 5 images of Zhuozhou, China, on September 7, 1999, showing top-of-atmosphere (TOA) reflectance; Level-2 surface reflectance (SR); and Level-2 surface temperature (ST), in Kelvin (K). View fact sheet at Landsat Collection 2 Level-2 Science Products (usgs.gov).

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. 

The city of Kathmandu, Nepal, seen at the bottom left of this Landsat 9 image, lies in a valley south of the Himalayan Mountainsbetween Nepal and China. Glaciers, and the lakes formed by glacial meltwater, are visible in the top middle of this image.

In the Western U.S., in places like the Navajo Nation as seen in this Landsat 9 image, Landsat and other satellite data help people monitor drought conditions and 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.
