A new psychoanalysis of decade - old research advise that NASA ’s first rover missionary work to the Red Planet 20 days ago may have explored the edge of a Martian ocean the size of it of California .
In 1997 , the blank agency sent its first rover advert Sojourner to Mars by the Pathfinder spacecraft in an endeavor to test the Martian mega - outpouring guess , a theory that explains how the planet ’s large epithelial duct – the largest in the Solar System – come into being following a cataclysmal torrent around 3.4 billion years ago . Sojourner took images from areas around a marine spillover landscape painting that depict the channels to be 10 times shallower than depths estimated by the conjecture when compare against orbital observations of the channels from 50 years ago during the Mariner 9 spacecraft . Many within the scientific community argued that the epithelial duct were alternatively created by lava current or other debris .
Writing inScientific Reports , researchers from the Planetary Science Institute reanalyzed former inquiry and argue that the channels were in fact carved by an ancient massive rising tide .

“ Our paper shows a washstand , with or so the surface surface area of California , that separates most of the mammoth Martian television channel from the Pathfinder landing place site . detritus or lava catamenia would have filled the basin before reach the Pathfinder landing place web site . The very existence of the catchment area requires cataclysmal floods as the channels ’ primary formational mechanism ” said study author Alexis Rodriguez in astatement .
research worker say that the landing place situation of the rover was a spillway of the ancient ocean . The presence of this sea – which is similar to the Aral Sea in that both miss discrete shoreline – could have prevented certain fluvial current and rather allowed shallow spillovers .
“ The basin is extend by aqueous deposit with a distribution that precisely match the inferred extent of inundation from likely catastrophic floods , which would have formed an inland sea , ” Rodriguez aver . “ This ocean is approximately 250 km ( 155 mil ) upstream from the Pathfinder landing web site , an observation that reframes its paleo - geographic mount as part of a marine spillway , which formed a land roadblock separate the inland sea and a northern ocean . "

moreover , the view that Mars could have been sculpt by flowing water supply means that there is a possibleness that life may have once thrived on it .
