Railroad Valley Playa
The Railroad Valley Playa, located in east central Nevada, measures about 80 miles long and nearly 20 miles wide, and is a vast and wide-open landscape.

Watering the Sahara
In a remote part of the Sahara Desert in Egypt, center pivot irrigation fields fill the landscape. Thanks to the Landsat archive, we can see how dramatically this area has changed over the last 35 years. But until the growth in irrigation, this part of the world hadn't changed much from a satellite's perspective.

Landsat's Calibration and Validation
Engineers and scientists from both Landsat and Sentinel missions are working together to calibrate observation data and validate its quality to improve the science using these resources.

Every Pixel - Landsat's Sensors
On board Landsat 8 are two sensors that capture data about earth's surface. Here is an explanation of the instruments that capture every pixel.

Every Pixel - Processing Data
Once the ground stations receive data from Landsat, there's still a lot of processing to make every pixel usable. Here's an overview of some of that work.

Eyes on Earth Episode 74 – A Satellite Cross Calibration Mission
When the first Landsat satellite launched 50 years ago, it was the only game in town in terms of civilian land remote sensing. In the years that followed, a host of satellites have launched to serve similar purposes. But that data doesn't always play well together.

Eyes on Earth Episode 32 - Lunar Calibration
Calibration teams at the USGS EROS Center use a variety of methods to make sure the data collected by Landsat satellites are an accurate representation of the Earth’s surface.

Eyes on Earth Episode 4 - Cataloging Earth Observation Satellites
Earth observation used to be the province of a handful of countries with satellite technology. Today, hundreds of satellites built all over the world are launched every year. This episode of Eyes on Earth talks about the explosive growth in the civilian and commercial remote sensing and EROS’ role in it.
