TanDEM-X Delivers First 3D ImagesBonn, Germany (SPX) Jul 23, 2010 On 22 July 2010, researchers at the German Aerospace Center facility in Oberpfaffenhofen published the first 3D images from the TanDEM-X satellite mission. Just one month after the launch of TanDEM-X, which took place on 21 June 2010, DLR researchers have created the first digital elevation model - almost a week ahead of schedule. A group of Russian islands in the Arctic Ocean was selected for the first test. b>Precise to a few centimetres br> /b> This first elevation model shows amazing v ... read more |

Bonn, Germany (SPX) Jul 19, 2010On its launch date, 21 June 2010, roughly 16,000 kilometres separated TanDEM-X from its twin satellite, TerraSAR-X. Now, that distance has shrunk to just 2000 kilometres. The time has come for the relative movement between the two satellites to be slowed down, and for them to be set up for formation flying. To accomplish this, the Flight Dynamics Group at the German Space Operations Center ... more  
Pasadena CA (SPX) Jul 16, 2010On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake-level changes on Saturn's largest moon, Titan-the only other place in the solar system seen to have a hydrological cycle with standing liquid on the surface. ... more 
Pasadena CA (SPX) Jul 16, 2010Ontario Lacus, the largest lake in the southern hemisphere of Saturn's moon Titan, turns out to be a perfect exotic vacation spot, provided you can handle the frosty, subzero temperatures and enjoy soaking in liquid hydrocarbon. Several recent papers by scientists working with NASA's Cassini spacecraft describe evidence of beaches for sunbathing in Titan's low light, sheltered bays for moo ... more |
