Eyes on Earth

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. This stunningly visual product grabs the public’s attention—and then leads to conversations about the value of remote sensing with satellites.

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. And while remote sensing scientists work with the deep archive of Landsat and other land data available from the USGS EROS Center, everyone can put themselves on the timeline of Landsat data. Citizen science projects allow anyone to participate in the observations that help us understand the world around us.

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. In this episode of Eyes on Earth, we learn how members have explored strategies for the effective use of archived Landsat data and integration of future data, and how they have helped identify Landsat user needs for upcoming satellite sensors, including those on the future Landsat Next.  

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. In this episode of Eyes on Earth, we talk about some of the collaborations that SDSU and EROS have both benefited from, including research projects centered on Landsat and other data sources, instrument calibration and validation, and trainings, presentations and workshops. SDSU faculty and EROS staff have ventured back and forth, and SDSU students have worked as interns and found employment at 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. These Phoenix systems have scanned millions of images and still have a lot of work to do.

The Don Lee Kulow Library has been supporting scientific research at EROS since before the facility opened its doors in 1973. In this episode of Eyes on Earth, librarian Carol Deering explains how, rather than becoming obsolete with the advent of instant access to online journals, libraries are even more crucial for the discovery of previous studies and for gauging the reach and real-world effects of research done by EROS scientists. She also talks about the history of EROS and describes a one-time quest for documents that stretched from UC Berkeley to the Library of Congress to Australia and Kenya.

AmericaView aims to advance Earth observation education through a network of programs based at universities in more than 40 states. In this episode of Eyes on Earth, we talk about AmericaView’s goals and how AmericaView and its member states explain remote sensing efforts to society in a variety of ways, including outreach to students who range from elementary to graduate school. We also give examples of the organization’s remote sensing research and describe AmericaView’s ties with the USGS and with Landsat.

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. While we cannot predict the future, it does look promising that Landsat 8 can sustain that continuity for more years to come.

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. Most can telecommute these days, but in this episode of Eyes on Earth, we discover how essential employees ensure there is in-person continuous monitoring of Landsat ground station operations during winter weather—sometimes even requiring an overnight stay.

Designed to last three years, Landsat 5 was launched in 1984 and transmitted data until the launch of Landsat 8 in 2013. In this episode of Eyes on Earth, we learn about some of the challenges—and adrenaline rushes—Landsat 5 gave the flight operations team as it aged, as well as the fondness our two guests came to have for the satellite’s unique personality and the whole team as they served on it during the satellite’s twilight years. In October 2022, the Flight Operations Team won the 2020 Group Pecora Award during the 22^nd^ William T. Pecora Memorial Remote Sensing Symposium.
