Voyager 1 made it to the edge of the solar system


The spacecraft "Voyager 1", launched into space in 1977, reached the outer limits of the solar system. This was at a meeting of the American Geophysical Society, told the experts that supervise the mission of the unit. Synopsis of the story is given on the portal

"Voyager 1" flew 17.4 billion kilometers and is in an area called gelioschit (heliosheath). The boundaries of the solar system is isolated from the behavior of flying from the star of the charged particles (solar wind). Initially, they fly at high speed and the repulsive particles from interstellar space. Gradually the speed of the solar wind drops, and in a certain area, called the boundary of the shock wave (termination shock), particles change their direction (turn).

Gelioschit is located just outside of the shock, and is followed by the first of the conventional boundaries of the solar system — the so-called the heliopause (heliopause). It is expected that the "Voyager" will overcome this limit and will leave the solar system in 2014 (according to other classifications Solar System extends from the upstream boundary). The unit is close to the heliopause at about 61.2 thousand miles per hour.

Scientists determine how outer space is the unit, estimating the velocity of the various particles of the solar wind around it. When "Voyager" will cross the boundary of the solar system, its detectors must register a sharp fall in the number of hot particles and the simultaneous increase in the number of cold particles. Learn about the different boundaries solar system can be found here.

"Voyager 1" was launched 16 days after the device-the "twin", "Voyager 2". The second is "Voyager" is moving on a different route and a little slower running mate (his speed is 56.3 thousand kilometers per hour) and is now at a distance of 14.1 billion kilometers from the Sun. Both devices work on nuclear fuel.
