The largest-ever solar boat

American scientist’s Agency NASA makes known plans to launch in 2014, the year of the largest in the history of the solar sail. Sail area of 1.2 thousand square meters. The name of this project served as a famous story by Arthur C. Clarke of 1964 Sun jammier, which refers to the regatta "solar boat". Side length of the sail is almost 38 meters high, and it will produce L" Grade - the company that in the late twentieth century sent experimental" inflatable "antenna on the ISS. 

This year sailboat must be approved by NASA, then begin ground tests. Presumably He will live at a distance of about 3 million km from Earth.

The material for the sail Welles' Kempton - polimidnaya film developed by DuPont. Leaf thickness is only 5 microns, and the total mass of the sail will be just over 30 pounds and is used, for example, astronauts in spacesuits and flexible electronics. The film is commonly used in flexible electronics. Astrophysicists believe that this technology will bring great benefit to the study of asteroids, in the analysis of space weather, as well as for interstellar flight in the future. It is significant that the first boat was launched by the Japanese in 2010, the year, and an area of about 10 square meters.
