Elephants counted from space for conservation At first, the satellite images appear to be of grey blobs in a forest of green splotches - but, on closer inspection, those blobs are revealed as elephants wandering through the trees. And scientists are using these images to count African elephants from space. The pictures come from an Earth-observation satellite orbiting 600km (372 miles) above the planet's surface. The breakthrough could allow up to 5,000 sq km of elephant habitat to be surveyed on a single cloud-free day. https://www.bbc.com/news/science-environment-55737086 A mammoth task made easier!
