Ocean used to wash Martian shores – Russian scientists

There used to be an ocean on Mars about 3 billion years ago and its remains can still be observed, Russian scientists say.

“Our studies have shown that an ocean existed in the Utopia Planitia region on the Red Planet,” Mikhail Ivanov from Space Research Institute of the Russian Academy of Sciences told ITAR-TASS news agency.

The glaciation of the ocean began during the Hesperian Period, which lasted on Mars about 3.5 – 2.9 billion years ago, the planetologist said.

“At that time, according to our hypothesis, the planet had constant hydrosphere and in the Utopia Planitia region there was an ocean, which was a rounded basin of impact origin,” he explained.

According to Ivanov, the evidence, which proves the existence of an ocean on Mars, are the huge muddy whirls in the Utopia Planitia, distinctive terrain and readings obtained from research vehicles.  

The Utopia Planitia is the largest recognized impact basin – formed by a collision with another celestial body – in the solar system, with an estimated diameter of 3,300km.

The Hesperian Period is also characterized by the appearance of lava fields, which began covering with ice, and that might’ve caused the glaciation of the Martian ocean, he added.

The scientist also said that there are reasons to believe that a biosphere existed on the Red Planet during the period as formations similar to fossilized remains of microorganisms were discovered in three meteorites of Martian origin.

In June, NASA’s Opportunity rover discovered traces of water on the Red Planet, confirming earlier finding by the Curiosity research vehicle.

The robot analyzed clay like formation on the Martian surface, which could only be formed in the presence of a large amount of water, which the US researchers described as neutral and nearly fresh.

But the US rovers are still unable to discover methane gas on Mars, which would prove that life used to exist on the planet.

The destructive force was 3.9 million,not 3 billion years ago. The entire solar system is not nearly one billion years old - but rather 40 million years old only.

so the Russian scientists are developing a megawatt-class nuclear drive, that would take them to mars in about 33 days which is 20 times faster than conventional rockets, to bring back Hydrogen Gas ?
i believe its your comment that's full of Hydrogen Gas.
this is besides the fact that Anti-Gravity Propulsion will be developed and in use before any one the above even make it to the launch pad.

[quote name='Tex Lahoma' time='29.10.2013 15:29']he headline should be: Ocean use to wash Martian shores – Russian scientists

The first line of the story should be: There use to be an ocean on Mars about three billion years ago...
Please if you can't understand English. Don't come on this panel again. After all why don't you run for a post at the US congress. You're very good at discussing nonsense.



  



You are speaking utter nonsense. The headline reads correctly.
