In this episode of Eyes on Earth, we talk about the 50-year history of EROS efforts to preserve the environment and conserve energy. EROS was born in the ’70s, the same decade as Earth Day, the EPA, and the oil crisis.

In this bonus material for episode 97 of the Eyes on Earth podcast, the three guests, all engineers at USGS EROS who started the Earth As Art project, talk about their favorite Earth As Art images.

Satellites capture an incredible variety of views of Earth. In this episode of Eyes on Earth, we talk with the three engineers at USGS EROS who started the USGS Earth As Art project. The Earth As Art origin story is an example of the initiative and creativity of EROS staff.

In this episode of Eyes on Earth, we talk with Peder Nelson about generational science and the responsibility we have to future generations to study our changing planet. It takes more than just data to make sense of land change.

The members of the five-year Landsat Science Teams, led jointly by the USGS and NASA with a strong tie to EROS, have brought a wide breadth of expertise, backgrounds and geographic locations to the table.

South Dakota State University opened its Remote Sensing Institute even before the launch of Landsat 1 and the selection of South Dakota as the location for EROS.

Working with film has always been part of EROS’ 50-year history. How did EROS end up with an extensive film archive, and how are we making that data available to users? In this episode of Eyes on Earth, we talk about the custom scanners built in-house from discarded parts to digitally capture historical aerial photos and declassified spy satellite images.

The Don Lee Kulow Library has been supporting scientific research at EROS since before the facility opened its doors in 1973.

AmericaView aims to advance Earth observation education through a network of programs based at universities in more than 40 states.

Originally called the Landsat Data Continuity Mission, Landsat 8 launched on February 11, 2013. In this episode of Eyes on Earth, we talk about the 10^th^ anniversary of Landsat 8 being in orbit and its value to the remote sensing community.

When the snow gets deep and the wind blows, it can be challenging for workers to travel to the USGS EROS Center, located several miles north of Sioux Falls, SD, on what used to be farmland.

Designed to last three years, Landsat 5 was launched in 1984 and transmitted data until the launch of Landsat 8 in 2013.

The USGS EROS Center is the home of the Landsat satellite archive. This data center and science center located on a former farm near Sioux Falls, SD, is one of the largest civilian archives of land imaging in the world.

Landsat 7’s nominal science mission ended in April 2022 after nearly 23 years of acquiring Earth imagery from 705 kilometers above the Earth. Landsat 7 is now in an extended science mission after having its orbit lowered by about 8 kilometers to make way for Landsat 9.

When disaster strikes, near-real-time images of its effects can be invaluable. In this episode of Eyes on Earth, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022.

ECOSTRESS, or ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, data provides variables related to plant water stress, including evapotranspiration, evaporative stress index and water use efficiency. The NASA Land Processes Distributed Active Archive Center (LP DAAC) at EROS provides storage and distribution of ECOSTRESS data.

The Global Ecosystem Dynamics Investigation, or GEDI, instrument on the International Space Station acquires lidar waveforms to observe the Earth’s surface in 3D. The GEDI lidar measures the height and density of objects, so it provides information such as surface elevation and tree canopy height and cover.

The Landsat satellites have been collecting Earth imagery for more than 50 years. A key piece of equipment that moves the data from the spacecraft to the archive so researchers can use it is the antenna at the EROS Center. The antenna and its radome have a fascinating history of their own that adds to the overall Landsat story.

ECOSTRESS, which stands for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, collects land surface temperatures in an effort to answer questions about plants’ use of water. The NASA Land Processes Distributed Active Archive Center (LP DAAC) at EROS has provided storage and distribution of ECOSTRESS data for four years now and counting.

The Landsat archive at EROS contains an unparalleled 50 years of Earth observation data. But with earlier technologies, some Landsat scenes were collected and stored only by international ground receiving stations rather than in the central archive at EROS.
