NASA Landsat Program Shows Drought Conditions
You’ve probably used Google Earth or other mapping sites that allow you to zoom in to see real images of your city or town. The grandfather of that technology is NASA’s Landsat, and it’s celebrating its 40th anniversary.
Landsat is a satellite that captures an image of the entire surface of the Earth every 16 days.
The photos can track the health of plant life and measure evaporation rates, and NASA scientists say you can see a big difference between Minnesota and the southern states dealing with the worst of the recent drought.
