Research into Venus: traces of a turbulent past
As is the case on the Earth, the surface temperature on Venus changes in relation to topographical height: in the lowland plains, the temperature is higher, while in the mountains it is lower. Armed with the knowledge of how high a region is, it is possible to forecast the temperature there. In the Lada Terra uplands, close to the South Pole, it was possible to prove the existence of minor variations in the forecast temperature. Scientists from the German Aerospace Center (DLR) succeeded in this endeavour in collaboration with colleagues from Finland, Italy and France, using readings from the European Space Agency’s Venus Express space probe. The researchers attributed these variations in temperature to differences in the composition of the solidified lava, which could be ascribed to the fact that the volcanoes were created at different times.
