New artificial satellite images of Mars may challenge the theory that the major planet was too cold to sustain pee on the surface , suggesting alternatively the creation of 20km - panoptic lakes along the planet ’s equator . But what does this think of for Martian history ?
A enquiry squad take by Dr Nicholas Warner from Imperial College London ( University College London also participate ) analyzed images send back from NASA ’s Mars Reconnaissance Orbiter and believe that they ’ve establish grounds of lake from a period antecedently believed to be full of subzero idle words , as Warner explains :
Most of the inquiry on Mars has focussed on its former history and the recent past . Scientists had largely overlooked the Hesperian Epoch as it was think that Mars was then a frozen wasteland . Excitingly , our study now record that this middle period in Mars ’ history was much more dynamic than we antecedently think .
The team reached its conclusions by comparing persona of depression on the surface of Mars with landscape from Alaska and Siberia , leading them to conceive that – despite previous theories to the opposite – the Mars of three billion years ago must have admit running H2O on its aerofoil . If truthful , then this could offer raw areas of exploration for those looking for evidence oflife on Mars , as the lake bottom would have been potential home ground for microbial lifeforms . Alternatively , it might be grounds that we should start preparingAdelaide Brookefor a space mission forty - nine long time from now .
