Flying in close formation with its twin satellite, TerraSAR-X, TanDEM-X will generate the most consistent and highest-resolution digital elevation map ever of the Earth — 12m = 40ft. pixel pitch. It will take three years to image all 150 million square kilometers (58 million square miles), in the process generating more than 350 TB of raw data. Here's where to go as the time approaches for live streaming."
