Life on Mars 3: More Study of NASAs Mars Photos

A third meteorite, the Shergotty, contains features suggestive of biofilm remnants and microbial communities. All of these samples provide tantalizing hints of the possibility of life in the early history of the red planet. But a fresh examination of the surface has the potential to reveal even more insights into the evolution of life on Mars.

The Viking 1 lander set down in July and didn't go silent until November Viking 2 landed in September and kept working until April Followed up with images from the Viking orbiters, the crafts provided detailed images of the surface that revealed that the surface of Mars was dry, but contained landforms that indicated it may not have always been so. Gullies , ocean beds, signs of erosion, and the vast polar caps inspired hope that Mars could have at one point hosted life. When NASA set the first lander down on the Martian surface, one of the experiments performed sought traces for life.

Though Viking's results were deemed inconclusive, they paved the way for other probes into the planet's environment.

Life on Mars

Landers and Rovers Since Infographic ]. Exploration of Mars was put on hold for more than two decades. When examination of the planet resumed, scientists focused more on the search for habitable environments than for life, and specifically on the search for water. The slew of rovers, orbiters, and landers revealed evidence of water beneath the crust, hot springs — considered an excellent potential environment for life to evolve — and occasional rare precipitation. Although the Curiosity rover isn't a life-finding mission, there are hopes that it could pinpoint locations that later visitors might explore and analyze.

Future mission to Mars could include sample returns , bringing pieces of the Martian crust back to Earth to study. More experiments could be run by hand on Earth than can be performed by a remote robot explorer, and would be more controlled than meteorites that have lain on Earth. But the hunt for Martian life may be stymied by concerns over how to prevent infecting the Red Planet with Earth life.

Current international policies impose heavy financial burdens that make exploring potentially habitable regions of Mars an extra challenge. Schulze-Makuch, a researcher at Washington State University, and his colleague Alberto Fairen of Cornell University authored a commentary article published in the journal Nature Geoscience arguing for less-strict protection measures for Mars.

The transfer of material from Mars to Earth and presumably back again has sparked some debate about the possibility of contamination early in the history of life. Some scientists argue that a meteorite from Earth could have traveled to Mars — or vice versa.

Life on Mars: Exploration & Evidence

Debates rage over whether or not tiny organisms would be hardy enough to survive the voyage through a freezing, airless, radiation-filled vacuum and kick off life at its new home. The idea of such seeding is not limited to interactions with Mars. Some have proposed that debris from outside the solar system could even be responsible for spawning life on Earth. But in terms of the Red Planet, it is possible that scientists might one day find life on Mars — and it could be a close relation. And if so, did it spawn us or did we spawn it?

As the author, I feel that I need to put in a few words about this book, because I feel it is of extreme importance to all the people of Earth. This book is my first book, and it has a few drawbacks, I know, it's not very thick, sizewize, although HUGE in significance , and some of the pictures are not just animals but are there to show water and plants, and traces of humans, and some of the images are very pixilated due to extreme enlargement, but nevertheless, its importance cannot be underrated.

The thing is, it shows there IS life on Mars! I see everywhere on the internet and television programs about Mars that this point is somehow unknown and unrealized by scientists worldwide. Scientists say there is no life on Mars. And these images I have collected are living proof. In this book, I start by showing that there IS liquid water, which scientists seem to not see. Then I show that there ARE plants, something else that seems to have eluded scientists.

And, furthermore, there are animals Then, to even my amazement, there is human life on Mars. I must admit I have had a bit of trouble convincing others, which is understandable, considering the way people tend to hang their beliefs on their government and scientific opinions. But this book shows, without a doubt, that the judgements of scientists regarding life on Mars is the biggest and costliest blunder of the human age.

This needs to become common knowledge, taught in our schools. This is one of the most significant discoveries in the history of mankind. Life on Mars 2: One person found this helpful. A fairly superficial discussion of the subject. Several of the images do not show evidence of possible life. However, the book is an addition to the very small body of literature on this topic, even if not in the class of Barry DiGregorio's well researched books, and is arguably valuable in that regard.

The author analyzed NASA photos and comes up with his own conclusions, opening the dialogue that there are plants, animals, bugs, dams and buildings. He shows the photos and explains why he thinks all this. He seems very intellectual and serious about the possibility of life on Mars. This is a slender picture book with 46 pages.

There are detailed captions, identifying such possible animals as crocodiles, snakes, and hippos.

A habitable environment

I would have liked to see more and hear more discussion of this topic and seen more photos analyzed. He says another book is coming! I give the author props for interesting analysis of the photos from NASA. Are there plants on Mars? I think I will say yes, I do believe that. I don't know yet, but it is definitely something to consider. I am intrigued to read more.

This is not a particularly scientific book. It is for the layperson, which I certainly can appreciate as the proper medium for conveying a message to the average person.
