Scientist: Life similar to Earth's existed on Mars for millions of years
Russian scientist, Doctor of Geology and Mineralogy Alexander Portnov has given an affirmative answer to the longstanding question whether life once existed on Mars.
"Life which resembled the Earth life existed on Mars for millions of years and it went extinct just recently, to which there are numerous proofs," Portnov said on Saturday.
He presented a theory, according to which life on Mars died out due to the loss of oxygen from the Martian atmosphere as a result of a huge asteroid impact on the southern part of the planet.
"The Martian surface is red, which is the color characteristic of planets which have or used to have life of our type, i.e. photosynthesis. It is red because the upper layer of the planet, about one kilometer thick, is made of iron hydroxides," the expert said. It took five-times the amount of oxygen in the Earth's atmosphere to make this layer on Mars, he said.
"The process lasted for billions of years. Mars used to have oxygen in its atmosphere, and its evolution painted the planetary surface red," Portnov said.

Nasa's Orion spacecraft prepares for launch in first step towards manned Mars mission
Thursday’s test flight will be the furthest a built-for-humans capsule has flown since 1970s Apollo moon missions but astronauts must wait seven years at least.
Nasa’s quest to send astronauts out into the solar system will begin this week with a two-laps-around-Earth test flight.
The new Orion spacecraft is not going to Mars just yet; Thursday’s debut will be unmanned and last just four and a half hours. But it will be the farthest a built-for-humans capsule has flown since the Apollo moon missions, shooting 3,600 miles out into space in order to gain enough momentum to re-enter the atmosphere at 20,000mph.
The dry run, if all goes well, will end with a Pacific splashdown off Mexico’s Baja California coast. Navy ships will recover the capsule for future use.
This initial Orion is rigged with 1,200 sensors to gauge its durability for the day when astronauts do climb aboard. Advertised destinations include an asteroid to be corralled in lunar orbit for human exploration in the 2020s, followed by Mars in the 2030s.
“We’re approaching this as pioneers,” said William Hill of Nasa’s exploration systems development office. “We’re going out to stay eventually … it’s many, many decades away, but that’s our intent.”
Lockheed Martin built the capsule and is staging the $370m test flight for Nasa.
Orion is Nasa’s first new spacecraft for humans in more than a generation, succeeding the now retired space shuttles.
Unlike the capsules under development by two US companies for space station crew transport, Orion is meant for the long haul, both in time and space; it would be supplemented with habitats for potential Mars trips.
After studying images from Curiosity’s mast cam, I have found not only that the Martians live a subterranean existence in the active areas but also have a elaborate rail system which they are actively expanding, a devastated Air base under repair, an ancient port with many ship wrecks and an active military.
NASA has been less than truthful about the habitability of Earthlings on Mars but someone is leaking unedited images for those who wish to find them,
The only reason the major powers are racing for a “dead” planet is to annex free real estate and with the blessing of the Martians who are following our Rovers every step of the way.
Oh and yes. The many pics of the locals are definitely Humanoid.
Would anyone like to share my information and interest?
Incredibly, there is a pattern of evidence showing that NASA/JPL have lied to us about the density of the Martian atmosphere. They claim that at the mean surface level it is less than one percent of Earth's sea level atmospheric density. If this was true, the sky seen from the surface of Mars would be black...yet in some pictures (where the color wheel on the lander is not distorted) it is light blue...indicating a fairly dense, thick atmosphere. On others (where the colors on the wheel are way off) the sky is pink. NASA says this is due to dust suspended in the air...but, even with the low Martian gravity, such thin air could not suspend enough dust to have any effect. Such thin air could produce, at most, the faintest wisps of clouds, but orbiter and lander pictures show, at times, large cloud masses and overcast skies. Liquid water cannot exist at under one percent of our sea level pressure; ice, when warmed, would sublimate directly into water vapor. But several official orbiter pictures show large, deep melt water ponds, with small chunks of ice floating on the surface. Nor could such thin air produce the dust devils that have been photographed, nor the planet wide dust storms that are higher than Olympus Mons, where the air is even thinner. Finally, the lander parachutes would not function in such thin air (yet they, too, are opened miles above the surface). Remember that the men who parachuted from balloons over 20 miles above the Earth had to fall for miles before opening their parachutes.posted by William B Stoecker at 9:42 AM EDT | Discussion (5)
We are a team of 6 students from the Université catholique de Louvain (UCL) and we are taking part in a research project developed by the Mars Society. It consists in a realistic simulation of a scientific mission on Mars in a space-analog base in the Utah desert. We will conduct a series of experiments to test equipment and scientific protocols in martian living conditions in the Utah desert. The main goal of this mission is to identify all the difficulties that scientists would have to face while caring out their experiments on Mars. Furthermore, the result of our experiments will be used afterward in a didactic way or even published for some of our research project. A description of those projects can be found in the annex below.
Thereby, the Mars Society aim is to promote Mars exploration among the general public and to the governments through intensive lobbying and trough concrete scientific and technical projects. One of its main projects is the Desert Research Station (MDRS) in which we are going to participate. In practice, each participating team will carry out experiments and will test different aspects of the astronauts' everyday life : habitat ergonomics, community life, technical difficulties, freeze-dried food, etc. A report of these experiments will be written in order to improve different aspects of the base, of the equipment and of the experimental protocols. Thus this project has a real practical significance since our results will be taken into account for a future mission on Mars !
Then we are looking for a financial contribution by an Indiegogo campagne.
Thank you for the help.

They dont have a really fast propulsion system like nuclear fusion powered rockets. People on the way will be exposed to so much radiation they will surely get cancer!
Chemonuclear Fusion is a type of low energy nuclear fusion that has been shown to produce energy in two experiments. Aneutronic nuclear fusion can provide unlimited electric power without polluting the environment with radioactive waste and greenhouse emissions. Chemonuclear processes in small dense white dwarf stars accelerate the rate of nuclear fusion and cause them to explode in spectacular supernova explosions.
The mission of the Chemonuclear Fusion Project is to raise awareness of this new and vitally important source of environmentally clean energy and to promote research and development.
The Chemonuclear Fusion Project is soliciting volunteers to help our crowdfunding and educational campaigns. Our crowdfunding webpages will soon be up and running. We want people to post to discussion groups and help us get the word out that aneutronic chemonuclear fusion might be the radiation free way to power the world if we can get the funding to build and test reactors.
Artists can help us design T-shirts, mugs, and promotional items to sell and give away to our contributors. Writers to write promotional materials and post to web forums are also wanted. Video producers and professional and amateur scientists who can help the public understand the concepts of chemonuclear fusion are encouraged to contact us also.
Visit our facebook page and give us a like. We welcome your comments and questions!

I would like discuss a lot of things about this, there is a lot about sliding spring we don't know about, but yet its journey is coming to our neck of the woods with a near miss with mars less than half the distance our moon is from earth, what do you all expect?posted by Troy Jackson at 2:02 PM EDT | Discussion (1)
Since the original anaglyph is very difficult to watch in stereo when enlarged.
As a result, surprising scenery has been in sight.
