Explainer: how do satellites orbit the Earth?

8,000 satellites orbit Earth, capturing images every single day. But for TED Fellow and food security specialist, Catherine Nakalembe, those aren’t just pictures — they’re lifelines for farmers. In her TED Fellows Film, she explains how she uses satellite data to map crops and guide disaster responses to help communities across Africa recover faster and build resilience against everything from flood damage to drought and beyond: http://t.ted.com/XZvf48m | TED Fellows
