NASA and USGS's Landsat Satellite's Global Perspective (video) NASA/Goddard Space Flight Center Share Print E-Mail Loading video... Caption Celebrating the 40th anniversary of the 1972 launch of the Landsat 1 spacecraft, this is a "greatest hits" montage of Landsat data. Throughout the decades, the Landsat satellites have given us a detailed view of the changes to Earth's land surface. By collecting data in multiple wavelength regions, including thermal infrared wavelengths, the Landsat fleet has allowed us to study natural disasters, urban change, water quality and water usage, agriculture development, glaciers and ice sheets, and forest health.
