The Mars One Project has announced ambitious plans to establish a permanent human colony on the red planet within the next ten years. The project would cost $6bn, which would come from the global audience of an interactive reality show on the candidates for the colony, but critics say the timetable is too ambitious.

More than 200,000 people have applied to go to Mars - and never return.

Dutch engineer Bas Lansdorp plans to establish a human base on Mars in 2023.

Before that he needs to scrape together $6billion (£3.8billion) - and find willing volunteers to take the trip.

The risky journey to Mars would take about seven months to complete.

If the crew survive they will have to deal with temperatures of -55 C - and there'd be no way back to Earth.

It's possible that the mission could be beamed back to Earth as a reality TV show.

Space agencies including Nasa say the technology to establish a human colony on Mars does not yet exist.

Nasa has suggested it will send astronauts to Mars within 20 years.

Thus, according to forecasts of Australian scientists, by 2300, due to global warming, humanity will not be able to exist normally on Earth. A change of the thermal regime will change the moisturizing regime. All this may undermine the natural water cycle. The speed of the increase of temperatures and the reaction of the entire climate system to this factor will play a decisive role in the process.

According to Australian experts, in 300 years, more than 40 percent of land will be flooded. The remaining part of the land will quickly use up all available resources and become unsuitable for human life. The scientists say that in 300 years, average annual temperatures will grow by 12 degrees, which will have a devastating impact on people.


Como dice Stephen Hawking:

"We must continue to go into space for humanity. We won't survive another 1,000 years without escaping our fragile planet,' he said. "Spreading out into space will have an even greater effect. It will completely change the future of the human race and maybe determine whether we have any future at all," he said in Los Angeles.


Aunque no es tan sencillo:

For example, flying to Mars will take a few years, but a human being simply can not leave their home planet for such a long time - human physiology and biology are closely connected with the Earth. Human body can function properly only under the conditions of gravity. The devastating effects of weightlessness can be seen by looking at astronauts returning to Earth after a long stay in space. These bodies are so weak and exhausted that they can not even move without assistance.

All this pales in comparison with negative changes that may occur after the flight of man to Mars. Astronauts suffer from heart diseases. After one week in weightlessness, the human heart becomes significantly smaller in size, which reduces the volume of the engine of our body and increases blood pressure.

After several months of life on the ISS, astronauts, when back on Earth, suffer from persistent dizziness and even temporary blindness. The blood circulation to the brain is not sufficient enough in space. Space explorers also have problems with the muscle tissue, especially with leg muscles. Negative changes occur in metabolism as well. The level of fat oxidation decreases, which may eventually result in the replacement of muscle tissue with fat tissue. Weightlessness is a great danger to bone tissue. In weightlessness, a human being loses up to two percent of bone tissue a month. Thus, during a three-year journey to Mars, astronauts may lose about half of their bones ...

Is Mars going to be the last stop for manned space flights?

A manned flight to Mars has became a fixed idea recently. According to scientists, in the next 3-4 decades, man will be able to land on Mars. But people can never get enough. When Mars is conquered, people will try to fly farther. No one says that it is impossible, but there are many obstacles. Thus, the director of the Institute of Space Research, Lev Zelyony, believes that humanity should not delude itself in vain illusions. He is convinced that Mars will be the end point of our space flights. Man will not fly farther.

According to him, space radiation will become the biggest obstacle. Even on Mars, human beings will not be able to stay for a long time - they will die from radiation sickness.

Mars One aims to launch a robotic lander and a communications satellite, to send to the Red Planet by 2018, it announced on Tuesday. Lockheed Martin, which has worked with NASA on its Mars missions, will build the lander, while the communications satellite will be built by UK firm Surrey Satellite Technology Ltd (SSTL).

The aim of the unmanned lander is to provide proof of concept for some of the technologies that are important for a permanent human settlement on Mars, the firm said.

The Mars One Astronaut Selection Program received more than 202,586 applications from people around the world seeking to be among the first to obtain a one-way ticket to live on the Red Planet.

Organisers said applicants come from over 140 countries, with the largest coming from the US (47,654), India (20,747), China (13,176), Brazil (10,289) and Great Britain (8,497).

By 2015, six to ten teams of four individuals will be selected for seven years of full-time training. In 2023, one of these teams will become the first humans ever to land on Mars and live there for the rest of their lives.

In the coming years, a demonstration mission, communication satellites, two rovers and several cargo missions will be sent to Mars. These missions will set up the outpost where the human crew will live and work and it is planned to have a human settlement on the Martian surface by 2023.

The US is already in the early stages of plans to land humans on the surface of Mars in 2036, Charles Elachi, head of NASA’s missions to the Red Planet, told delegates at the Arabian Business Forum 2012 in Dubai in November.

“We don’t have a programme [to send a man to Mars] but we are starting to plan,” Elachi, who heads up the Jet Propulsion Laboratory (JPL), the Pasadena-based NASA agency that constructs and operates robotic planetary spacecraft, said.

“Interestingly enough we can go to Mars every four years or so. Every 18 years they get very close. We are thinking not for 2018 but 2036 [for a human mission],” he added.

Elachi’s team at JPL successfully masterminded the landing of a one-tonne vehicle – called ‘Curiosity’ – in a deep crater on the surface of Mars in August 2012.

The rover has now begun a two-year mission to look for evidence that the Red Planet may once have supported life, but Elachi said plans to send humans to Mars is possible.

There are about 10 private companies engaged in space transport at present, including SpaceX, created by billionaire PayPal co-founder Elon Musk, and Blue Origin, founded by Amazon’s chief executive Jeff Bezos. Space tourism, driven by companies such as Sir Richard Branson’s Virgin Galactic and Jeff Greason’s XCOR Aerospace, aim to give the super wealthy a taste of what it is like to be an astronaut by sending them into suborbital space.

Aboard Virgin Galactic’s SpaceShipTwo, passengers will see the view that eluded mankind until 50 years ago, and one that only about 500 people have seen in reality: the curvature of the Earth set against the blackness of space. The two-hour journey will blast six passengers and two pilots nearly 70 miles into the sky, experiencing about five minutes of weightlessness before turning back and landing at Spaceport America in New Mexico, frequently described as the world’s first purpose-built commercial spaceport.

“Hallan el primer planeta del tamaño de la Tierra que se encuentra en zona habitable,” RT Actualidad, 25 Mar 2014. El astrónomo Thomas Barclay (NASA) ha afirmado en una conferencia científica, de la que se han hecho eco en Twitter algunos asistentes, que se ha hallado la primera exotierra en la zona habitable gracias al telescopio Kepler de la NASA. El autor prefiere mantener en secreto los detalles hasta tener preparada una publicación científica.
