Mars is simply a desolate wasteland, but scientists person discovered remnants of ancient stream systems that erstwhile had nan correct conditions to support life.
Researchers astatine Pennsylvania State University re-analyzed information collected by NASA's Curiosity rover astatine Gale Crater, uncovering nan formations were habitable bodies of h2o acold much abundant than antecedently believed.
The squad identified shallow benches and short, truncated ridges they telephone 'noses' wrong nan landscapes that could beryllium indicators of ancient stream deposits successful craters.
These bodies of water are besides believed to behave for illustration those connected Earth - 'important for life, chemic cycles, nutrient cycles and sediment cycles,' researchers said.

Benjamin Cardenas, adjunct professor of geosciences astatine Penn State and lead author, said: 'We're uncovering grounds that Mars was apt a satellite of rivers.
'We spot signs of this each complete nan planet.'
The study was conducted by mapping nan erosion of ancient Martian ungraded utilizing a machine exemplary trained connected outer data.
The information came from NASA's Curiosity and 3D scans of layers of stone called strata that were deposited complete millions of years beneath nan Gulf of Mexico seafloor.
In designing their machine model, Cardenas and his squad recovered a caller usage for 25-year-old scans of Earth’s stratigraphy that lipid companies collected.
The squad reanalyzed information from NASA's Curiosity at Gale Crater successful nan confederate hemisphere of Mars, adjacent to nan Martian equator
Researchers said that nan study revealed a caller mentation for communal Martian crater formations, which, until now, person ne'er been associated pinch eroded stream deposits
Cardenas said nan scan 'provided an perfect comparison to Mars.'
The squad simulated Mars-like erosion utilizing nan 3D scans of actual, recorded stratigraphy connected Earth.
When they ran nan simulation, nan exemplary revealed erosional Martian landscapes that formed topographic benches and noses alternatively than fluvial ridges, appearing almost identical to landforms observed by nan Curiosity rover wrong nan Gale crater.
Researchers said that nan study revealed a caller mentation for communal Martian crater formations, which, until now, person ne'er been associated pinch eroded stream deposits.
'We person everything to study astir Mars by amended knowing really these stream deposits tin beryllium interpreted stratigraphically, reasoning astir rocks coming arsenic layers of sediment deposited complete time,' Cardenas said.
'This study is not a snapshot but a grounds of change. What we spot connected Mars coming is nan remnants of an progressive geologic history, not immoderate scenery stiff successful time.'
Previous studies that mapped Mars concluded that fluvial ridges are believed to beryllium nan inverse of a riverbed.
The ridges are coming only successful nan confederate hemisphere, wherever Gale Crater is located - though it is person to nan Martian equator.
However, nan caller study has suggested that nan bench-and-nose landforms could besides beryllium ancient stream deposits.
'This suggests that location could beryllium undiscovered stream deposits elsewhere connected nan satellite and that an moreover larger conception of nan Martian sedimentary grounds could person been built by rivers during a habitable play of Mars history,' Cardenas said.
'On Earth, stream corridors are truthful important for life, chemic cycles, nutrient cycles and sediment cycles.
'Everything is pointing to these rivers behaving likewise connected Mars.'
