The Future
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is a second, very similar spacecraft launched successfully on June 21, 2010 from Baikonur Cosmodrome in Kazakhstan. Since October 2010, TerraSAR-X and TanDEM-X fly in a close formation at distances of only a few hundred metres and record data synchronously. This unique twin satellite constellation will allow the generation of global digital elevation models (DEMs) of an unprecedented accuracy, coverage and quality – a consistent DEM of the Earth’s land surface is envisaged to be acquired and generated within three years after launch. This DEM is to feature a vertical accuracy of 2m (relative) and 10m (absolute), within a horizontal raster of approximately 12x12 square meters, slightly varying depending on the geographic latitude.

Famous quotes containing the words the future and/or future:
“The difference between Pound and Whitman is not between the democrat who in deep distress could look hopefully toward the future and the fascist madly in love with the past. It is that between the woodsman and the woodcarver. It is that between the mystic harking back to his vision and the artist whose first allegiance is to his craft, and so to the reality it presents.”
—Babette Deutsch (1895–1982)
“We live in an age when to be young and to be indifferent can be no longer synonymous. We must prepare for the coming hour. The claims of the Future are represented by suffering millions; and the Youth of a Nation are the trustees of Posterity.”
—Benjamin Disraeli (1804–1881)
“He who never sacrificed a present to a future good or a personal to a general one can speak of happiness only as the blind do of colors.”
—Olympia Brown (1835–1900)
