Finland is expected to solar sails for space within
According to NASA's Space Network reported that scientists in Finland has proceeded smoothly, then one may choose to use "turbo" powered by solar sails are expected to charge 3 years in the first space flight test. Finland will take advantage of this invention have a long, positively charged using the solar wind the rope flight, do not need any other fuel or propulsion.
Finnish Meteorological Institute R & D researchers such solar sails junin Pekka • Jane said: "out of the solar system, the measurement of interstellar space no one interfere with the gas, dust, plasma and magnetic field should be to do the solar sails of paramount importance. "The initial appearance of solar sails will include a 5 miles (8 km) long rope of a smaller prototype, which focus on high elliptical Earth orbit. Through this model, Jane junin and others will be able to use a detector of acceleration to the spacecraft measured the solar wind pressure.
The first test whether the solar sails can be carried out smoothly, it is necessary to gather the basis of whether some eight million U.S. dollars (500 million euros) Shade sailof the funds. At present, from Finland, Germany, Sweden, Russia and Italy, researchers are developing the different components of solar sails. Previously, as a result of launch failure or other failure, and testing of solar sails to start the efforts were mostly failures. In 2005, Russia and the United States joint research and development of solar sails in two minutes with a rocket launch failure of the accelerator. Russia in 1999 and 2001, the two efforts ended in failure, only success in 2004, Japan launched a small solar sails. Other concept of solar sails using the Earth-launched spacecraft microwave to promote the highest speed, rather than ride the solar wind.
Solar sails of a successful deep-space mission will no longer need fuel, can greatly reduce costs, to the great benefit of mankind. Solar sailing team in the solar system can reduce the cost of transportation of goods. Jane told the NASA Space Network junin said: "The ice from the asteroid in Earth orbit to generate rocket propellant, such a possibility might be a wise application. In orbit means that the production of rocket fuel is no longer required after rocket from the Earth. In addition to reducing the near-Earth orbit in addition to the cost of all space activities. "
Solar sails are not only for further pave the way for space exploration, the development of cheaper and more user-friendly, such as reusable launch vehicle is also very necessary. However, solar sails to confirm the expansion of human technology will contribute to the activities in the solar system. Junin Jane said: "The beginning of the long-awaited project of the asteroid resource utilization, to our long-term health of civil society in the face of the earth survive very significant."
Junin Jane said: "The task will be to confirm and test our theory, and allow us to design precise to have been the appropriate test to confirm the integrity of the task force." 2 solar panels will provide an electron gun energy, which the electron gun can be charged to ensure that the spacecraft ropes, using the same electrically charged solar wind to generate thrust to promote solar sails. In order to research and nike shoes development of these ropes, researchers are aluminum or copper alloy wire for research. The first flight will also be testing a rechargeable solar sails "turbine." Radio frequency wave energy to the solar wind particles penetrate electronic heating device (might be able to promote the thrust produced). Junin Jane said that the principle of the theory difficult to use simulation or analysis, but should be very easy to be tested in space.
