It has long been established that Mars once had water on its surface. But a new study suggests that between 3 and 4 billion years ago, the Red Planet was warm and wet enough to have massive rains and running water, an environment that may have sustained life.
The new study presented at the Goldschmidt Geochemistry Conference in Barcelona compares the models of Mars mineral deposits with those observed on Earth to support the hypothesis.
"We know that there were periods when the surface of Mars was frozen; we know that there were periods when the water was flowing freely," Purdue University

Horgan continues: "But we do not know exactly when these periods were and how long they lasted. to show us these earliest rocks, so we have to use Earth-related science to understand the geochemistry of what might have happened there. Our study of atmospheric conditions in radically different climates, like the Oregon Cascades, Hawaii, Iceland and other places on Earth can show us how climate affects the model of mineral deposition, as we see on Mars. "
Analyzing the models observed in the Martian mineral data collected by the Roof Curve and NASA's CRISM spectrometer and comparing it with these have been observed in various locations on Earth, and researchers have found evidence that Mars has had at least one prolonged period of rainstorms and running surface water.
"Silicon dioxide signals have been identified from the orbit of Mars in the Amazon n perillation terrains and the Curiosity rover has identified silica-rich crystalline materials in lake sediments in the Galle Crater," the study said. Mars phases could form in cold climates during punctured melting events. The most common Noah signatures, however, are crystalline clay minerals in compositionally zoned stratigraphy, for which the closest terrestrial analogues [sic] are known to be deep-atmospheric analyzes that are formed under a constant climate dominated by rain. "
" If this [silica signatures] is so, it is important for the search for a possible life for Mars, "adds Horgan.
For years, scientists have acknowledged that there was water on Mars, including recent evidence of clay spotted on the Curiosity rover. However, so far, scientists have discussed what the climate of Mars is, whether the water was frozen or the planet had warm temperatures and conditions to allow water to flow and potentially sustain life.
Even if the conditions of Mars were running water, this is no longer the case. According to Space.com, Mars today has an average temperature of approximately 80 degrees Fahrenheit. Add to the thin atmosphere of the planet, which is largely carbon dioxide, and it is difficult for Mars to sustain life as we know it.
Horgan went on to say that researchers understand that the building blocks of life on Earth "developed very soon" after the formation of the planet, adding that flowing water was "essential to life's development."
"So evidence that we had early, running water on Mars will increase the chances that simple life may have evolved at about the same time as on Earth. We hope the Mars 2020 mission will be able to consider take these minerals closer and begin to meet exactly what conditions existed when Mars was still young. "

hopes for the Curiosity Rover, which "has a few more years to go before its nuclear power system degrades enough to significantly limit operations, "may provide additional clues to the planet before the launch of the Mar s Rover Mission 2020.
Mars is emerging ever greater in America's space future.
In November, NASA announced that it has chosen the location where its Mars rover will land on the Red Planet.The rover is expected to reach the surface of Mars on February 18, 2021. NASA's long-term goal is to send a manned mission to Mars in the 2030s.
However, former astronauts, including Apollo 11 astronaut Michael Collins, believe we should skip a mission to return to the moon, scheduled for 2024, and "shoot directly to Mars."
