More than three decades after the launch, a NASA spacecraft to fight hard for an inch longer be able to pass through the edge of our solar system.

The plane is Voyager 1, which now is 11 billion miles from the sun which has been exploring the outskirts of the solar system since 2004.

The scientists said Monday (5 / 12), Voyager 1 has entered new territory in the solar system, dubbed as a zone of stagnation.

Voyager 1 is still one step closer to truly out of this solar system. This will make the spacecraft made ​​the first man to cross into interstellar space.

The aircraft has enough battery power to last until 2020. But scientists think Voyager 1 will reach interstellar space before that year, in a matter of several months or years.

Chief scientist Ed Stone of NASA's Jet Propulsion Laboratory said the arrival time of the Voyager 1 into interstellar space is not clear because there has never been a plane to travel that far.

"The journey is still continuing," Stone said in a meeting of the American Geophysical Union in San Francisco.

In the past year, Voyager 1 has been exploring new territory. This region seems tostagnate due to solar storms have been reduced dramatically. So high energy particles from the outside seep into. That's the sign that Voyager 1 was in the doorway of interstellarspace.

The scientists hope to see some signs of when Voyager 1 crossed the border, including changes in the magnetic field direction and type of wind. Interstellar wind is slower, cooler,and denser than the solar wind. (Media Indonesia).
