International Space Station Imagery
Sand dunes in the central Sahara Desert
high res (3.0 M) low res (105 K)
ISS034-E-070070 (6 Jan. 2013) --- One of the Expedition 34 crew members aboard the International Space Station used an 800mm lens on a digital still camera to record this image of sand dunes in the central Sahara Desert in the country of Chad on Jan. 6, 2013. Scientists have been using imagery from the orbital outpost over the last decade to compare the very noticeable and costly movement of dunes like these, in some cases as far away as hundreds of meters, crossing highways and moving over farm lands and causing heavy environmental damage. Comparison of the photography from Earth orbit helps scientists to predict potential movement, and such prognostication can lead to measures being put into place that help mitigate damage.
