Interstellar expploration

Exploration is interstellar travel using the spacecraft through the stars, both manned and unmanned. The concept of interstellar travel is still a concept that many in science fiction. Because of the fact that interstellar travel is very difficult to be realized.

Many scientific works have been published about related concepts. It takes time travel and work techniques sufficient to do so, both between generations and unmanned journey seemed possible, even in the highly sophisticated technology. NASA has been involved in this research topic for several years, and has made a number of theoretical approaches.

The main challenge of this trip is the mileage is very, very far, because it did not take a no less. With the technology we have today took decades to thousands of years to achieve.
