Night Sky Network members joined us on Tuesday, February 13 when NASA's Theresa Arvidson shared the history of the ongoing Landsat program, and updated us about the upcoming Landsat 9 mission.

Conceived in the 1960s, the Landsat program launched its first satellite in 1972. Landsat has gathered more than 45 years of information about Earth’s land surface, chronicling how it has changed over time, pioneering global land monitoring and making breakthroughs in assessments of natural resources, especially agriculture, forestry, and geology. The technical aspects of remote sensing advanced as the Landsat program proceeded to accumulate an unprecedented global data archive. This talk combines a little history, some technology, and a fair amount of science with lots of beautiful images of our Earth’s surface.

About Theresa Arvidson:
Terry Arvidson started her Landsat involvement at GE over 37 years ago and followed its evolution with Martin Marietta, Lockheed Martin, and now Leidos Innovations. As Senior Systems Engineer, she has participated in all mission phases—from proposal through development; from operations to on-orbit decommissioning—and all mission elements from spacecraft and sensors to data processing and distribution. All of this has accorded her a “big picture” perspective of the Landsat program. Terry enjoys working with stakeholders including the science community, international stations, and public outreach, she enjoys sharing her passion for all things Landsat.

Landsat imagery is important for understanding and tracking changes over time.  Check out the Landsat educational resource Tracking Change Over Time below.  This activity booklet discusses how you can engage visitors to your outreach in looking at images from different times to notice change, and to explore detector resolution.

The history and heritage of Landsat is conveyed in a new publication from the American Society for Photogrammetry and Remote Sensing (ASPRS).  Landsat's Enduring Legacy details the development of Landsat, and  some of the challenges it faced in becoming the iconic window on the Earth it is today.
