Our Eyes In The Sky For Four Decades
Since 1972, NASA’s Landsat program, or Earth Resources Technology Satellite (ERTS) as it was originally called, has been beaming essential (and sometimes beautiful) overhead data about our planet.
While many are familiar with Landsat pictures, today we’re reversing the view to bring you photographs of the first satellite in the Earth observation program.
These pictures show the original Landsat-1, or ERTS-1, as well as the first piece of information ever received from the satellite. Click through the photoset to learn more about a NASA program which, to date, has completed more than 200,000 orbits and three million images of the Earth.
