It’s a proud moment for NASA and our nation too as NASA's Landsat program has completed its 40 years of services successfully and is still continuing giving a perfect view of earth from space.

It is the first satellite of the Landsat series and was launched on July 23, 1972 from Vandenberg Air Force Base in California into space. It has proved itself to be the world's longest-running Earth-observing satellite program.

With this 40th anniversary of NASA's Landsat program, it is an honor to respect how Landsat gave us a critical perspective of our planet. This is a proud feeling that the satellite is still continuing in helping the experts get the clear picture of the planet Earth from the space and enabling them to understand the big changes that are occurring in the planet.

NASA Administrator Mr. Charles Bolden said that "With this view we are better prepared to take action on the ground and be better stewards of our home”.

The Landsat records have always served with global coverage showing large-scale human activities bringing the change in our planet and natural surroundings too. It was an effort of the United States to keep a track of all the changes occurring and their direct benefits/loss for human and environmental health.
