NASA claims Mars had water..mystery rock appears on Mars..mysterious triangular object also found on the moon
NASA’s decade-old Mars rover, Opportunity, has found evidence that life-friendly fresh water once pooled on the red planet’s surface, reinforcing similar discoveries made by newcomer Curiosity on the other side of the planet, scientists said on Thursday.
Opportunity, along with its now-defunct twin, Spirit, landed 10 years ago for concurrent 90-day missions to look for clues of the past existence of water.
Both rovers did so, confirming evidence collected by orbiting spacecraft that Mars, the planet believed to be most like Earth in the solar system, was not always the cold, dry desert that appears today.
In August 2012, Curiosity, equipped with an onboard chemistry lab, arrived for follow-up investigations to determine if Mars had other ingredients essential for supporting life.
The answer, returned very early in the ongoing mission, was a definite ‘yes’.
On the other side of the planet, meanwhile, Opportunity has been analyzing water-bearing rocks at the rim of an ancient impact crater called Endeavour.
Rather than the chemical fingerprints of acidic, salty water found at previous sites, Opportunity discovered telltale clays called smectites that form in Ph-neutral water.
“It’s like drinking water,” planetary scientist Ray Arvidson, with Washington University in St. Louis, said in an interview.
“This would have been a niche for whatever life at the time existed,” he said.
The finding adds to an emerging picture of a planet that spent its first billion years or so warmer than it is today, with pools of fresh water on its surface, scientists say.
Gradually, water activity declined and what did exist became acidic, scientific findings reveal, and then, beginning about 3 billion years ago, Mars dried up.
The small, round object suddenly popped up in pictures taken 12 days apart by the US space agency’s decade-old Opportunity rover.
On December 26, 2013, it was not there. On January 8, it was. But what is it?
“It looks like a jelly doughnut, white around the outside, red in the middle,” said Steve Squyres, the principal investigator of the Mars Exploration Rovers.
He described the tint as a “weird deep red color, not a Martian kind of red,” which is more of a rusty hue.
One thing is for sure. This is not a fried, sugary pastry.
“We have looked at it with our microscope. It is clearly a rock,” he told reporters in a briefing to mark 10 years since NASA’s solar-powered Opportunity landed on the Red Planet.
But it is a kind of rock no Earthling has seen before.
Squyres said scientists believe the rock, named “Pinnacle Island,” got there when the aging rover did a pirouette turn in the dusty Martian soil and knocked loose a chunk of bedrock that rolled a short distance downhill.
Images of a triangular mystery object on the surface of the moon were posted by a researcher under the username WowForReeel.
Man may not be the only one to have flown to the moon.
In good news for conspiracy theorists, images of a bizarre-looking, unexplained “alien spaceship” on the surface of the moon have emerged — and some scientists are confused.
The “craft” is triangular and appears to have seven light-like dots along its edges.
ok..that is not a rock..i dont know what it is but its not a rock in my opinion..and what the hell is that shape on the moon?..bizarre..
mars had water..yeah maybe..so what?..doesnt mean humans or aliens lived there previously and it doesnt mean you have mastered the history of the world..in fact we know virtually nothing about our universe compared to its size..and what we do is made up of theory and guesswork..those “habitable” earths you always hear about..thats not done with any surface monitoring..its all theory and wether a star has a shadow or gives off a glow..we are not that smart yet..dont be fooled..
