Space age humanitarians
Jon Lebkowsky, 8 Dec 04

NewScientist.com reports on the use of satellites by Respond Humanitarian Global Mapping Services to coordinate the movement of aid workers in Darfur, where it can take as long as 10 days to travel 120 kilometres by road, especially during rainy seasons, when normally dry creeks are flooding. Respond combines data from nine different space satellites, including ESA's Envisat, the largest Earth-observation spacecraft ever built. The European Space agency reports that satellites are also used to locate hidden water locations and identify optimal locations for new camps.
