Just as it sounds. There are already two seasons on Earth to simulate the extreme conditions on Mars astronauts suffer. Conquest of Mars appears to be serious. U.S., Russia, Europe and China are developing projects in order to complete the most ambitious space mission of all time, although there are still insurmountable technical difficulties. And NASA believes that it has enough qualified personnel to achieve, because of the "brain drain" (foreigners studying in the U.S. and then return to their countries).
The trip is valued at 423,000 million euros, for two reasons that expensive: the distance (56 million kilometers) and the cost of fuel to try to escape Martian gravity on the return journey, despite being three times smaller than Earth's.
The American project is called Vision and European Aurora, but many are saying will not succeed if you do not join forces in a project common.
the moment, the NASA and European Space Agency assist the Mars Society, an NGO founded by a Chicago peculiar genius named Bob Zubrin, who first was not taken very seriously and plans colonize Mars, but is slowly getting the backing of the scientific community.
was endorsing the idea of \u200b\u200bbuilding a station in a place where conditions resembled those of Mars. And that place is on Devon Island in the Canadian Arctic. The first attempt in 2000 failed because releasing the material to build a parachute, it destroyed the majority and the workers left. In a second attempt trial, before the end of the summer polar Eskimo using labor could be constructed, and given the name of Mars station.
is located on a frozen crater. It is a cylinder with two-storey laboratory, decompression chamber, dining room, gym, toilets, showers and a kind of cabins where scientists display their sleeping bag. Someone is always working, never sleep all at once. The scientists come from different countries and are not strangers rubbed by extreme living conditions that lead. Their behavior is studied by psychologists. subsequently built another in the Utah desert. It is an area with a similar climate to the equatorial regions of Mars: large temperature differences between day and night and many storms. The placement of the lightning on the outside of the station was very difficult, because scientists had to go into a hyperbaric chamber to get out. The movements are done in a kind of quads, where scientists are equipped with a suit and a backpack of 15 kg. weight on the back. Difficulties
mission
- The surface of Mars is a barren desert full.
- The air concentrations of CO2 is so high that you can not breathe.
- The difference in temperature between day and night is 60 degrees.
- There are countless tornadoes and hurricanes.
- Astronauts should bring everything to feed itself, material to build a permanent base for isolation of high solar radiation, vehicles, food and machines for subsurface water ice, if true the data obtained from the Mars probe Spirit. Apparently, this robot would have to be decommissioned, but for now continues to send information. And recently one of its wheels got stuck in a dune and sand removal revealed the presence of silica in the soil, closely related to the presence of water, which seems to confirm that millions of years ago Mars was life possible.
- The mission lasted two and a half: half each way and 18 months on Mars.
- Six months that the journey would stay in weightlessness, which will cause them severe muscle atrophy.
- Do not know the effects that the trip would have on the kidneys of the crew, because it is very common stone formation in astronauts.
- If they were exposed to radiation may develop into cancer, so it would be isolated.
- The isolation to which it would subject (900 days together without seeing the Earth and a communications delay of 40 minutes) lead to significant psychological distress.
- Do not leave aside the problem of sex. Practice in space is downright difficult. Nor is it clear whether to send three men and three women (and possible love problems), six men (too many male hormones) or six women (according to recent studies including working more than men).
- The shape of the current ferry is not valid for this mission. Should look instead to the Apollo who went to the moon.
- The fuel we know is not enough, and should be used or nuclear energy (with the problems that public opinion may raise), or developing that uses the solar wind, even advanced little.
- Scientists suggest that it would be better to establish a permanent colony, instead of returning to Earth, so we need to find people willing to return no more.
technological advances - NASA has developed a system to obtain drinking water from urine evaporated.
- crops are being tested landless, food also provide oxygen.
- To combat muscle atrophy are developing weightlessness weights and exercise bikes using electromagnetic fields.
- Development of drugs to prevent stones in the kidney.
the moment, the European Space Agency is looking to twelve people for a drill, ExoMars mission will search DNA and other signs of life on Mars and NASA is going to practice before the moon.
