A lot can change in five decades! How we talk, what we wear – it all evolves. But one thing that’s stayed consistent is our unique view of our home planet from above. Five decades ago, we at NASA partnered with United States Geological Survey (USGS) to launch a satellite called Landsat to see Earth from space. Now, we’re launching Landsat 9 – that’s right, the ninth in the series!
Join us for a road trip through the decades from the idea of an Earth-imaging satellite in the groovy 60s to the launch of Landsat 9 this year. Hop in!
Far out! In 1966, USGS proposed a satellite to image land all around our planet. Researchers worked with our scientists and engineers to design the satellite and figure out how it would work.
Here’s the lowdown: In 1970, we got approval to build the Earth Resources Technology Satellite, later renamed Landsat 1. The satellite launched in 1972 and provided the first digital data of Earth, repeated at regular intervals, which allows us to see changes as they happen.
In 1982, we launched Landsat 4, followed by Landsat 5 in 1984. These two satellites collected more wavelengths of light at higher precision, allowing for natural color images, which is totally radical, dude.
Wasssup, 1990s? Landsat 7 launched this decade, collecting even more data than previous Landsat satellites, enough to produce the first hi-res natural color map of remote Antarctica.
In 2008, our partners at USGS made all Landsat data available for free. This gave peeps around the world access to all the data they needed, unlocking innovation and creating economic benefits, like the ability to track crop health from space. Sweet!
In 2013, Landsat 8 began the modern era of Landsat observations. A new style of sensor and ground system made it possible to download much more and better data than ever before. Plus, a partnership with European Space Agency’s Sentinel-2 satellites gives even more regular observations. We heart that!
Now, we’re set to launch Landsat 9, a twin to Landsat 8. Two Landsat satellites with two instruments each will highkey change our view of Earth once again.
Now, on to the next 50 years of Earth observations! Stay tuned to watch Landsat 9 launch and start telling us even more about our home planet.
