"NanoSail-D" of the solar sail spacecraft
Is expected to launch at the end of
Solar sails contains almost a century of human dreams. As early as 1921, the Russian Konstantin Tsiolkovsky who raised a light-fan concept. Then, science fiction novelist Arthur C. Clarke novel solar sailing is to allow the concept of people.
A long time, NASA has been committed to the dynamic research spacecraft, hoping to find a way to replace the use of solar wind dynamic model of the deployment in outer space to the sun as a power source of solar sails. NASA's Marshall Space Flight Center decided in the summer and bringing this idea to reality, and in space, the establishment of a code-named NanoSail-D of solar sails. NanoSail-D solar sails will be SpaceX's Falcon One is responsible for the rocket sent to space, is expected to launch for July 29 to August 6 between. NanoSail-D will be sent to Earth from about 330-685 km of track, the entire mission will last seven days, the expiry of its mandate, NanoSail-D will be back in space.
NanoSail-D will be deployed in space, mankind's first solar sails, but also the first to pressure the sun as part of their orientation and orbit control of the main driving force of the spacecraft.
From space travel a reality that day onwards, leading to the universe, mankind has been only one way, and that is to rely on rocket thrusters. However, a solar sail technology has provided for mankind an alternative, and scientists believe that human spacecraft for interplanetary travel the greatest hope, because it does not have rocket fuel, as long as there is a place of sunshine, it will continue to have the momentum to accelerate the flight .
Solve the energy problem Astronautical
In the NASA Institute for Advanced Concepts specializes in solar sails of Dr. Zhu Bulun said that if the design is reasonable, in theory, solar sails can achieve the maximum speed of light 2% (6000 km / s), would be the case, will astronautics possible. By then, provide an impetus to such a spacecraft will not be the sun, but installed in the satellite enormous power lasers. Another advantage of solar sails is that it does not need fuel, no engine, it can carry more scientific instruments and goods. U.S. scientists said the solar sails and successfully launched into orbit, will be a milestone-like significance.
So far, the human rocket are the driving force for the spacecraft, rocket fuel and the need to consume oxygen for combustion, no matter how many will eventually run out of portable, so that mankind can travel in the universe is extremely limited scope. However, if we can successfully use this kind of stars such as solar light powered, then it would be possible to a final settlement Astronautical the energy issue. Milky Way, about 400 billion light-emitting stars, the number of extremely massive stars produce light, it is possible to send a solar sail
