The photos prove there is water flowing on Mars
Through photographs of the spacecraft and method of spectral analysis, scientists from the US Aeronautics Agency (NASA) confirmed on the surface of Mars existed liquid water.
Collection of photos proving there is water on Mars
On July 14, 1965, the Mariner 4 spacecraft flew to the position of the Martian surface 9,845km, recording the first close-up images of the planet.22 photographs of Mariner 4 reveal a pore surface with concave mouths.During this survey, scientists also confirmed that Mars has a thin atmosphere including carbon dioxide and magnetic fields.This is the first photograph of Mars, showing the area between the Elysium Planitia in the west and Arcadia Planitia in the east.(Photo: NASA).
The dark grooves stretching 100m down the slope can be the result of water flowing on the red planet.This hypothesis is validated when scientists discovered salt water at the edge of Hale Crater in Mars's Argyre basin.The existence of pyroxene minerals produces a green color above the grooves.The team published details of the findings in Nature Geoscience yesterday.(Photo: NASA / JPL / University of Arizona).
These dark grooves radiate from the edge of Garni Crater at the foot of Melas Chasm on Mars.According to scientists, saline water flowing on Mars may be the cause of steep slopes.(Photo: NASA / JPL / University of Arizona).
In the picture, the grooves run down the peaks to the west of Coprates Chasma located at the equator of Mars.NASA said, Corporates Chasma is a wide gutter of Valles Marineris, a system of canyons that runs east-west in the southern equator of Mars and as long as the distance from Los Angeles to New York, USA (3,940km) .(Photo: NASA / JPL / University of Arizona).
Dark grooves containing salt crystals were discovered at Horowitz Crater on Mars, at coordinates 32 degrees south latitude, 141 degrees east longitude.(Photo: NASA / JPL / University of Arizona).
The strange grooves less than 5m wide appear on the steep peaks of Mars in the warm season.They last long and then disappear in the cold season.This temporary feature is evidence of flowing water.However, so far, spectral data collected by spacecraft has not provided authentic information.(Photo: NASA / JPL / University of Arizona).
In the new study, Lujendra Ojha, a scientist at the Georgia Institute of Technology, Atlanta, USA and colleagues, looked at data obtained from the CRISM Mars spectrophotometer based on NASA's Mars Reconnaissance Orbiter.Their goal is to determine where the grooves will form.The CRISM system detects light wavelengths in visible and infrared form, reflected from the surface of Mars.According to NASA, at the visible wavelength, how reflected light is influenced by iron in minerals such as iron or iron oxide and is red in color.With infrared wavelengths, CRISM can determine the sulfate, carbonate, hydroxyl, and water content in mineral crystals.(Photo: NASA / JPL / University of Arizona).
