The Red Planet was as soon as BLUE: Mars was coated by 984ft-deep oceans 4.5 billion years in the past

Now a desolate pink desert, a brand new examine has claimed that Mars was as soon as truly predominantly blue.

Whereas researchers have lengthy agreed that our pink neighbour as soon as held water, simply how a lot water it had was topic to debate. 

Now, a brand new examine has revealed that 4.5 billion years in the past, Mars was coated by 984ft (300 metre)-deep oceans.

Researchers from the College of Copenhagen hope the findings may carry humanity one step nearer to answering a significant query: did Mars ever have life?

Proof that Mars as soon as held water 

Spirit and Alternative, NASA’s twin rovers, discovered proof of the presence of water enclosed in rock in 2007, when one in every of Spirit’s wheels broke and gorged a bit of stone.

Evaluation of the silica-rich layer found within the scratch steered it shaped within the presence of liquid water.

In 2008, the Phoenix lander was gathering geological samples, and so they disappeared after a couple of days.

Scientists thought these had been items of ice. This evaluation was confirmed when the lander later detected water vapour in a pattern. 

In 2012, Curiosity was meandering over an historic martian seabed when it examined plenty of rocks that had been uncovered to liquid water billions of years in the past.

The examine estimates that the oceans coated the whole planet, and will have ranged wherever from 984 ft (300 metres) to three,280 ft (1,000 metres) deep.

On condition that the planet is about half the scale of Earth, Professor Martin Bizzarro, from the Centre for Star and Planet Formation says that compared, there may be truly little or no water on our planet. 

This water was dropped at Mars by asteroids stuffed with ice, in line with Professor Bizzarro. 

Along with water, the icy asteroids additionally introduced biologically related molecules corresponding to amino acids to Mars.

Amino acids are used when DNA and RNA kind bases that comprise all the pieces a cell wants. 

Professor Bizzarro defined: ‘This occurred inside Mars’s first 100 million years. 

‘After this era, one thing catastrophic occurred for potential life on Earth. 

‘It’s believed that there was a big collision between the Earth and one other Mars-sized planet. 

‘It was an brisk collision that shaped the Earth-Moon system and, as the identical time, worn out all potential life on Earth.’

To achieve these conclusions, the researchers studied a meteorite that’s billions of years outdated. 

Talking to MailOnline, Professor Bizzarro defined that the meteorite was shaped 4.5 billion years in the past and is now ‘a fraction of the unique crust of Mars.’

‘Thus, it information the bombardment historical past of the planet,’ he defined.

Not like Earth, Mars would not have tectonic plates deep beneath its floor, because the searing molten rock has lengthy cooled to kind a rocky mantle. 

Because of this, the researchers observe that the crust stays static, holding the floor of the planet unchanged. 

This permits them to review Mars’ previous in a manner that might be not possible to do on Earth.

Professor Bizzarro added: ‘Plate tectonics on Earth erased all proof of what occurred within the first 500 million years of our planet’s historical past. 

‘The plates always transfer and are recycled again and destroyed into the inside of our planet. 

‘In distinction, Mars doesn’t have plate tectonics such that planet’s floor preserves a document of the earliest historical past of the planet.’

The brand new examine comes shortly after consultants claimed that historic microbes may survive for a whole bunch of hundreds of thousands of years beneath the floor of Mars in ‘suspended animation’. 

Researchers say a bacterium known as Deinococcus radiodurans may survive 280 million years on Mars – almost 300 instances longer than beforehand assumed – if it was buried 32 ft under the Red Planet’s floor.

D. radiodurans is also called ‘Conan the Bacterium’ and a ‘superhero of the bacterial world’ attributable to its toughness, which has even earned it the title of ‘world’s hardest identified bacterium’ within the Guinness Guide of Information.  

Like a muscle-bound film hero, it withstands assaults from acid baths, excessive and low temperatures, and even radiation doses.

Whereas Conan the Bacterium probably would not exist on Mars, the researchers consider an equal microorganism may exist on the Red Planet for the same time interval. 


The Mars Curiosity rover was initially launched from Cape Canaveral, an American Air Power station in Florida on November 26, 2011. 

After embarking on a 350 million mile (560 million km) journey, the £1.8 billion ($2.5 billion) analysis car touched down only one.5 miles (2.4 km) away from the earmarked touchdown spot.

After a profitable touchdown on August fifth, 2012, the rover has travelled about 11 miles (18 km). 

It launched on the Mars Science Laboratory (MSL) spacecraft and the rover constituted 23 per cent of the mass of the overall mission. 

With 80 kg (180 lb) of scientific devices on board, the rover weighs a complete of 899 kg (1,982 lb) and is powered by a plutonium gasoline supply. 

The rover is 2.9 metres (9.5 ft) lengthy by 2.7 metres (8.9 ft) broad by 2.2 metres (7.2 ft) in peak. 

The Mars Curiosity Rover Was Initially Intended To Be A Two-Year Mission To Gather Information To Help Answer If The Planet Could Support Life, Has Liquid Water, Study The Climate And The Geology Of Mars An Has Since Been Active For More Than 2,000  Days

The Mars curiosity rover was initially supposed to be a two-year mission to assemble info to assist reply if the planet may assist life, has liquid water, examine the local weather and the geology of Mars an has since been energetic for greater than 2,000  days

The rover was initially supposed to be a two-year mission to assemble info to assist reply if the planet may assist life, has liquid water, examine the local weather and the geology of Mars.  

As a consequence of its success, the mission has been prolonged indefinitely and has now been energetic for over 3,500 days.

The rover has a number of scientific devices on board, together with the mastcam which consists of two cameras and may take high-resolution pictures and movies in actual color. 

To this point on the journey of the car-sized robotic it has encountered an historic streambed the place liquid water used to circulate, not lengthy after it additionally found that billions of years in the past, a close-by space often known as Yellowknife Bay was a part of a lake that would have supported microbial life.
