In formation flight - TerraSAR-X and TanDEM-X
In October 2009 TanDEM-X, a satellite identical in construction to TerraSAR-X, will be launched. This artist's impression shows the formation flight of the two satellites, planned for January 2010, which will generate a three-dimensional digital elevation model of Earth.
