Your safety, do Shandong Xiang Electronic Technology Development Co., Ltd. Mars is a planet from Earth, it looks like a red planet. It in many places is very similar to Earth, where the atmosphere (just the atmosphere of Mars than Earth is thin and dry much more) and four seasons, so astronomers Mars called Earth's "sister star. Positive pressure air respirator so crowded planet overwhelmed, it is natural first thought immigration Mars. Immigrants Mars, must first Green Mars, NASA, the European Space Agency and the Japanese Space Center "Green Mars" plan, this the most mammoth project in the history of mankind will be divided into five periods, planned for the next 200-year period of time. Warm Period (2030-2080). The main task of this period of positive pressure oxygen respirator Mars rose to minus 40 ° C temperatures from minus 60 ℃. The main way scientists expected the construction of a chemical plant, a small nuclear reactor power generation, the release of the greenhouse gas, to produce substitutes similar to the Earth's ozone layer, to prevent the spread of heat on Mars. Consolidation period (2080-2115). When the temperature on Mars rising to minus 15 ° C, carbon dioxide, nitrogen, and the amount of water extracted from the crust of Mars began a large-scale increase in the Martian atmosphere continue to thicken, the air began to float in the clouds with liquid water began in Canyon accumulation, air respirators bryophytes grow in warmer zones. At this time, the population on Mars will be increased to about 50,000. People can take off the heavy spacesuit breathing respirator breathing mask and oxygen bottle to help people respirator on the speaker to replace the radio, people between calls more convenient oxygen respirator. At this time immigrants Mars scientists, engineers, doctors and technicians, about hundreds of people. Because of the atmosphere of Mars is very thin, it is difficult to resist the sun's ultraviolet radiation, and very little oxygen, the fire commanders respirator immigrants in addition to occasionally wear Aerospace clothes to go out for a walk most of the time spent in a special biosphere . Pioneered period (2015-2030). Spacecraft prefabricated on Earth teardrop-shaped capsule will be sent to the Martian surface. This capsule can accommodate 14 astronauts to live. Fire respirator Their mission is to grow crops on Mars experiment, analysis of Mars around the gas composition, dust situation and solar radiation, exploration and geological conditions, looking for signs of life in the past and the future. Of course, during this period of very hard astronauts. Mars air is too thin, long tube respirator dialogue, so the use of radio devices to go out to the aerospace activities to wear clothing to ward off the sun's ultraviolet radiation. Green Mars formation. When Mars's average temperature rose 4 ℃ -5 ℃, most of the polar ice and permafrost has been dissolved, have formed the rivers, lakes and even oceans, Mars began regular rainfall. Thick atmosphere protection, air inflatable pump on Mars transplant trees themselves thrive, the crops are growing well. Red and cold of Mars into a green planet, a good place for human travel, the happy homes of the settlers. Recovery period (2110-2150). After the stability of the atmosphere of Mars, the average temperature will rise to 0 ° C., some microbes began manufacturing the soil available for plant growth and development, and part of the green plants out of the greenhouse environment growth Mars on a short-term by inhalation Mars atmosphere to life. Mobile gas supply source of a large number of Earth immigrants to Mars to look for development opportunities, cottage industries, the service sector is a large number of vehicles and other transport running on Mars, a self-sufficient the biosphere small city began to form.
