July 23, 2022 marks the fiftieth anniversary of Landsat’s first launch in 1972. A joint program of NASA and the U.S. Geological Survey (USGS), the Landsat program introduced remote sensing from space and revolutionized the science and technology used in Earth science applications.

With continuous coverage since then, the satellite series provides the longest record of space-based land remote sensing data. Using this critical record of environmental and climate changes on Earth over the past 50 years, scientists and data users are able to monitor changes in land use by comparing the same areas days and even decades apart.

Today, Landsat’s unparalleled data archives are free, open, and accessible by anyone. Through training, funding, resources, and other support, the Applied Sciences Program empowers communities around the world to use Landsat and other Earth observation data to inform decision making and solve problems to improve life on Earth.

As noted by Applied Sciences Program Director Lawrence Friedl, "We wouldn’t be where we are today without Landsat paving the way."
