Astronomers have discovered a large lake of water just beneath Mars surface. The find could end a lot than century debate over whether the Red Planet has water. Some 12 miles from end stretche, and has been detected using a radar instrument called MARSIS the European Space Agency’s Mars Express spacecraft, which reached Mars fifteen years ago. The results have been published Wednesday in the journal Science. This is simply one study region, says whos, researcher Roberto Orosei. It is a prospect to believe there could be more yet to be uncovered. By starting radar pulses from the orbiter scientists found the lake.
Between 2015 and 2012, 29 radar samples were obtained by the team and used them to map the subsurface in the region and approximately a dozen miles wide. The European Space Agency’s Mars Express spacecraft used radar to discover a lake of water. Wed seen hints of subsurface attributes for years, but we couldnt replicate the effect from orbit says study co writer Andrea Cicchetti, whos on the MARSIS team. She says data resolution at the past has been simply too low. However the team found a brand new way to operate the tool that avoids processing data on the aging spacecraft and instead sends observations to Earth, allowing a higher sampling rate.
The discovery is particularly fascinating because underground lakes like this are also located near Earths poles, especially in Greenland and Antarctica. And in latest years, scientists actually drilled deep under the Antarctic ice into one of those, the subglacial Whillans lakes, which had been cut off in the surface for millions of decades. They found bacteria still live there in complete isolation. Scientists have also traveled deep underground to mines and found micro-organisms related to ancient species that once lived at aqueous environments much closer to the surface. Such migrations increase the possibility of the same thing happening on Mars as the water retreated, life moved deeper underground.
Nevertheless, whilst the find is tantalizing for astrobiologists keen to find alien life, its also a bit of a tease.
