Landsat 9 launched into orbit from Vandenberg Space Force Base on Monday, September 27, 2021, to carry on the legacy of a nearly 50-year record of continuous Earth observation that began in 1972. The days leading up to the event saw guests from around the world descend upon Santa Barbara County in California to watch the historic event take place. Over the next few weeks, we’ll bring you some of the interviews we collected with scientists, government officials and Mission partners. This episode of Eyes on Earth focuses on the day before the launch, when we spoke about the importance of the Landsat program with guests at the launchpad and a Landsat for Climate event.
