When Landsat 5 launched on March 1, 1984, Las Vegas was a smaller city. This image series, done in honor of the satellite's 28th birthday, shows the desert city's massive growth spurt since 1972. The outward expansion of the city is shown in a false-color time lapse of data from all the Landsat satellites.

The large red areas are actually green space, mostly golf courses and city parks. You'll notice the images become a lot sharper around 1984, when new instrument designs improved the ability to resolve smaller parcels of land.

These Las Vegas images were created using reflected light from the near-infrared, red and green portions of the electromagnetic spectrum (Landsat 5 TM bands 4,3,2 and Landsat 1-3 MSS bands 4,2,1).

Landsat data have been instrumental in increasing our understanding of forest health, storm damage, agricultural trends, urban growth, and many other ongoing changes to our land resources. Studies using Landsat data have helped land managers keep track of the pace of urbanization in locations around the world.

NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images with free distribution of data over the Internet. The next Landsat satellite, now known as the Landsat Data Continuty Mission (LDCM) and later to be called Landsat 8, is scheduled for a launch in January 2013.
