Solar sails flying the new direction of the future of aerospace
Years ago, the United States National Aeronautics and Space Administration (NASA) continued to organizations throughout the United States scientists to conduct research and experiment, trying to find a more energy saving and environmental protection of the aerospace force to replace the way of relying on the wind flight. The use of solar energy as a photon of the space vehicle's main power source, these scientists have pursued the ideal. So far, such cases only in science fiction appeared. However, by the end of July this year, NASA suddenly in their own official website claimed that in August to September, the Space X Falcon 1 (Space X Falcon 1) rocket will carry a photon to the sun as a driving force equipped with new solar sails washed up on space satellites.
This has to grab a new tool photon energy - solar sails of satellites, known as nano-flight-D (Nano Sail-D). U.S. June 10, 1973 launched Radioastron detector B,(Radio Astron-B), just as long as two antennas on the 450 meters, shape and large spiders are very similar, is the world's largest man-made satellite one. And these are huge in size compared to the satellite, this nano-satellite flight-D figure in the satellite family known as the mini.The main structure of the satellite is not more than 30 centimeters in length, the whole weight of the satellite is not more than five kilograms. And it is the core of weapons - solar sails, from aluminum outer layer of polymeric materials and internal components, almost equal to the total thickness of an ordinary sheet of paper. However, in the universe when it is fully opened their four small solar panels, it's a smooth will reach nearly 10 square meters. The sun's light in full by the photon energy, composed of corporations, as a result of force is mutual, solar sails cover the surface of aluminum metal will photon pushto go back, the photon will have a reaction to the solar sails. Is relying on this reaction, the spacecraft was pushingthe way forward. The sun is an inexhaustible supply of energy, from that point on, in the long-distance space travel in the use of solar sails aircraft, than the use of conventional rocket boosters better.

Government or the introduction of hundreds of billions of economic stimulus program of 460 million the company took over the aircraft Fuxi Building the People's Daily: Price control has been marked improvement in the effectiveness of 200 billion fund to fight the first day of the new short-selling cars in South clarification granted mobile 3G licensing has nothing to do with the 80 billion railway debt 6 days to issue 16 billion to buy almost no friction due to the existence of outer space, solar sails, once running, it will become a perpetual motion machine, its flight faster than relying on fuel to run faster than a rocket. Human desire to explore the universe, relying on the rocket boosters to achieve, and now, the sun may be able to fan the invention provides an alternative for human Aerospace way choice. In the NASA Institute for Advanced Concepts (NASA Institute for Advanced Concepts) specializing in solar sails project members of the expert group said that in theory, solar sails can achieve the maximum speed of 2 percent the speed of light - 6000 kilometers per second, and once the test success, which means that solar energy photon for interstellar navigation will become a reality. By then, the spacecraft on the enormous power of lasers, solar sails to power the expansion of a few thousand times more. The solar sail spacecraft does not need fuel, no engine, it can carry more scientific instruments and goods. U.S. probe Voyager (Voyager) to complete its space travel has spent three decades of time, and the same trip, solar sails aircraft may only take about ten years. Because solar sails start slow, and rocket compared to the long-term space flight in order to demonstrate the advantages. However, the scientists said that the solar sail technology is still enormous room for improvement, such as solar sails will be designed as Sunflower, can automatically detect the direction of the sun, or to increase the speed of it even if it is that the results will be exciting .
Although the launch is successful, or an unknown, and arranged by NASA to launch the next time also repeatedly delayed, but NASA is still on the nano-flight-D high hopes. NASA experts said that solar sails mankind one of the greatest inventions, the solar sails into orbit satellites, solar sails the successful launch of human space exploration with landmark significance. At the same time, NASA experts said the flight is only a technical test, once the actual situation show that solar sails can indeed aircraft navigation in the universe, then the near future, they will conduct more in-depth research.

● NASA will launch the first solar sails ● speeds up to 6000 kilometers / second ● Star Trek is the best hope for mankind Solar sail spacecraft is likely to be the future of mankind's only hope for Star Trek, it does not have rocket fuel, as long as it is in a sunny place, it will continue to have the impetus to speed up the flight. This year July 29 to August 6 during the day, NASA (NASA) is expected to officially launch a code-named
