The launch of Landsat 9 in September of 2021 represents a milestone for a joint USGS/NASA program that stretches back nearly 50 years. Landsat 9 will continue the legacy of unbroken, repeat Earth observations and contribute to our understanding of a changing planet. The primary USGS roles for Landsat satellites, which are built and launched by NASA, are to operate the ground system, process and archive the data, and distribute it to users around the world. On this episode of Eyes on Earth, we hear from two people who’ve been involved in the development of the Landsat 9 ground system to learn what it takes to bring Landsat data to the Earth and transform it into the data products and imagery we all recognize.
