Landsat takes a long look at El Paso and Ciudad Juarez.
For 41 years, USGS-NASA Landsat satellites have collected images of our planet...millions of them. Such images help everyone from scientists to city planners examine how the landscape changes with time. In one patch of desert, where the Rio Grande makes a border between the United States and Mexico, the Landsat fleet has captured hundreds of photo-like natural-color images. They show fields turning green and brown with the season; new urban and suburban developments expanding around El Paso, Texas, and Ciudad Juárez, Mexico; changing angles of sunlight; and clouds moving over the neighboring mountains. They also reveal subtle changes in the sensors as technology improves with each generation of satellite. Watch the video to see a multi-decadal, time-lapse view of this desert city.
