This allowed scientists to cross-calibrate the instruments, ensuring accurate and consistent data for long-term Earth observation. | Landsat | Facebook

Landsat In Action—Landsat’s Calibration and Validation In this USGS Landsat in Action video, Engineers and scientists from both Landsat and Sentinel missions talk about working together to calibrate observation data and validate its quality to improve the science using these resources. Quote to note from David Roy, Professor at South Dakota State University’s Geospatial Sciences Center of Excellence: “It’s a fantastic time to be a user of satellite data, if you’re in that moderate resolution dom

🌍✨ Ever wondered what it looks like to travel across half the world in just 15 minutes? NASA’s Landsat 8 satellite, also known as the Landsat Data Continuity Mission (LDCM), captured one continuous strip of Earth stretching 5,665 miles — from northern Russia all the way to South Africa! 🚀 Each pixel shows about 30 meters of ground, and the satellite’s camera covers a massive 185 km-wide swath in one pass. Normally, Landsat orbits the entire planet in about 100 minutes… but this “director’s cut

Landsat 8: 5-Year Anniversary

3.4K views · 153 reactions | Landsat's Next Chapter With a trio of smaller satellites that can each detect 26 wavelengths of light, the Landsat Next mission is expected to look very different from its predecessors that have been observing Earth for 50 years. This new plan for Landsat Next, a joint mission of NASA and the U.S. Geological Survey, is designed to provide more frequent, and finer resolution, data of the changing surface of Earth. | Landsat | Facebook
