NASA and the
U.S. Geological Survey this week celebrate Landsat's 30th anniversary
of imaging the Earth.
On July 23,
1972, NASA launched the first Landsat satellite, beginning the longest-running
record of Earth's continental surfaces as seen from space -- a record
unmatched in quality, detail, coverage and importance. This 30-year
archive of imagery, a scientific partnership between NASA and the
U.S. Geological Survey (USGS), provides invaluable historical detail
that helps us understand and protect our home planet.
In celebration
of the 30th anniversary of the first Landsat launch, NASA and the
USGS have assembled an exhibit called "Landsat: Earth as Art."
These images, created by the USGS using Landsat 7 data, introduce
the general public to the Landsat Program, administered jointly
by USGS and NASA. The USGS operates Landsat 5 and 7 and manages
the national archive of data collected by all the Landsat satellites,
distributing these data to researchers around the world.
