NASA | Continuing Landsat's 40-Year Legacy

The video discusses the Landsat program, highlighting its role in monitoring Earth's surface changes due to climate change and land use. It introduces the Landsat Data Continuity Mission (LDCM), also known as Landsat 8, a collaboration between NASA and the US Geological Survey. The video explains the technological advancements in Landsat 8, such as the push broom sensors, and the importance of free and open access to Landsat data for scientific research and applications.
