EXCLUSIVE: There WAS life on Mars but 'catastrophic' event wiped it out, scientist says

Last edited Fri Sep 11, 2015, 11:57 PM - Edit history (1)

LIFE probably did start on Mars, but a catastrophic event must have completely wiped it out, a scientist has claimed.



Lewis Datrnelll, a UK Space Agency research Fellow, believes early microscopic forms of life may well have formed on Mars billions of years ago, but a major environmental event later made the Red Planet completely inhospitable even to the single-celled organisms that may have formed.

Mr Dartnell, who is also author of The Knowledge: How to Rebuild our World from Scratch, a New York Times and Sunday Times best-selling book explaining how to rebuild society in the event of an apocalypse, said: "Something catastrophic has gone wrong on Mars environmentally."

He said the only life that would have developed before that would have been singled celled - "only the bacteria you would see under a microscope" - but whatever happened wiped out its chance of evolving into more complex creatures.

"...but a major environmental event later made the Red Planet completely inhospitable even to the single-celled organisms..."

Gee. Maybe they were burning fossil fuels and driving too many SUV's.

1. Nope,

 

it was caused by tiny leaf blowers.



Looks Martian to me.

3. Mar's Impact Crater: The Largest in Solar System Sparks Intense Scientific Interest

Recent analysis of the Red Planet's terrain using NASA's Mars Reconnaissance Orbiter and Global Surveyor spacecraft observations revealed what appeared to be by far the largest impact crater ever found in the solar system.

NASA’s Viking orbiters observed in the 1970s that the bottom two-thirds of Mars was about two miles higher in altitude than its top third. Planetary scientists have since bandied about two hypotheses to explain the dichotomy: either some odd internal dynamics of Mars generated a thicker planetary crust in the south, or the northern surface was blown away by a mega-meteor impact.

<snip>

The mystery of the two-faced nature of Mars has perplexed scientists since the first comprehensive images of the surface were beamed home by NASA spacecraft in the 1970s. A giant northern basin that covers about 40 percent of Mars' surface, sometimes called the Borealis basin, is the remains of a colossal impact early in the solar system's formation, the new analysis suggests. At 8,500 kilometers (5,300 miles) across, it is about four times wider than the next-biggest impact basin known, the Hellas basin on southern Mars. An accompanying report calculates that the impacting object that produced the Borealis basin must have been about 2,000 kilometers (1,200 miles) across.

That's larger than Pluto. The impact gouged out a crater the size of the combined areas of Asia, Europe and Australia, researchers reported in the journal Nature. It appears to have held an ocean in the early days of the planet, before Mars lost so much of its atmosphere and the water either sublimated away or froze beneath the surface.

An asteroid bigger than Pluto could ruin.. well, everything. I've also read that meteors have been found on the Earth, with origin from.. Mars...

8. And leftist "elite" wonder why people do not take scientists seriously anymore!!

Take a tiny bit of evidence and build a massive star trek episode out of it!!!

15. If educated people are considered of no consequence in some circles, so be it.

 

I can always get my oil changed somewhere else.

9. No catastrophe. The atmosphere leaked away due to Mars' low gravity

The force of gravity on Mars is 38% of that on Earth.

10. I'll bet some of those same sex tiny organisms wanted to get married and it pissed jeebus off

so he destroyed them. That's the only real answer.

12. No rotating iron core = tiny magnetosphere = constant irradiation of the surface

...which equals dead little bugs
