Life on Mars?...

Apparently so. Bacteria has been transported there on the Rover!

Nasa's Curiosity rover may have accidentally taken life to the red planet, it has been revealed.

Researchers found that swabs taken prior to launch revealed 377 types of microbe withstood the specialized spacecraft cleaning methods used by NASA ahead of launch.

Scientists from the University of Idaho recreated the conditions that Curiosity underwent during its trip to Mars - and found 11 percent of the 377 microbial strains survived more than one of those conditions.

Although spacecraft go through multiple cleaning steps to ensure that they bear no biological contaminants, previous reports suggest that Curiosity project developers did not follow these planetary protection protocols to the letter, according to Nature. 

Swabs of Curiosity’s surfaces before it was launched, including its heat shield and flight system, revealed 65 species of bacteria.

What about 'the face' that has been photoshopped since the 1970's?

Just a mountain formation nothing else. It has been photographed by various orbiting satellites.

'No name' if you look at the original picture you will see the rover was only 5 metres away from the figure which makes it less than 10cm tall.

Another thing that I remember didn't make sense about the pic is that it didn't move at all for almost 2 minutes whilst the Rover was taking the pics. Why freeze in that position? 
And this ignoring the first set of pics taken half hour earlier where the figurine seems to be in exactly the same position, but because it's grainier I have ignored it...look:

Could be an ancient statue?

Who knows.... the only way to find out for sure if it is a real object is to have more pictures from the same angle.

I remember the time you told me about natural rock formations that look like amazing statues.... it was a long time ago and I'm sure you will remember when you see the pic (I had to go find it amongst hundreds of pics I have saved).

Yeah, those are natural, no argument here.

But the ones in Mars may be natural too..... there's no way we tell.

Which is why evidence is so crucial. One way or the other.

Well, if the rover introduced Earth bacteria to Mars, the place is now contaminated

It could  well be a possibility, Len, but we don't know if the bacterium managed to survive the trip there and the hostile environment of the red planet.

Curiosity Rover Finds Nitrogen On Mars, Further Evidence That The Red Planet Was 'Habitable For Life'
The Huffington Post |  By Dominique Mosbergen
03/25/2015


Another ingredient for life has been found on Mars.

NASA announced this week that the Curiosity rover has discovered life-sustaining nitrogen on the Red Planet for the first time.

By drilling into Martian rocks, the rover is said to have located evidence of nitrates -- compounds that contain nitrogen “in a form that can be used by living organisms.” Nitrogen, as Discovery News notes, is essential for life, as it’s a building block of RNA and DNA.

The finding, NASA said, “adds to the evidence that ancient Mars was habitable for life.”

The space agency was quick to note that "there is no evidence to suggest that the fixed nitrogen molecules found by the team were created by life.”

“The surface of Mars is inhospitable for known forms of life,” NASA said.

Instead, the agency believe the nitrates are ancient and “likely came from non-biological processes like meteorite impacts and lightning in Mars’ distant past.”

Curiosity has previously found evidence of the other key ingredients for life, including organic molecules and liquid water.

It's highly probable that early life developed on Mars too before it got all dry!
