Voyager 1 flew to the edge of the Solar System


After a 33-year odyssey, NASA spacecraft Voyager 1 reached an area in which there is no outgoing solar wind.

NASA probe, launched 33 years ago for a detailed study of Jupiter and Saturn, entered the region where the fading stream of charged particles from the sun.

This final phase of the solar system should last another four years, as shown by computer models. But scientists, project managers, do not undertake to say how things will turn out in reality.

Voyager 1 is currently located at a distance of more than 17.3 billion miles from the sun, in the region known as the Heliospheric mantle, where the solar wind meets the interstellar magnetic forces and its motion becomes turbulent.

In June, Voyager 1 passed the information according to which he has gone beyond the upstream solar wind particles.

Flying at a speed of about 60,000 kilometers per hour, Voyager 1 continues its way to interstellar space. He is so distanced from the Earth that radio signals, traveling at the speed of light to reach the spacecraft for 16 hours.

Its twin, Voyager 2, flying at a slower pace, at a speed of 56,000 km / h, and will go beyond the solar system, to the south, a few years after Voyager 1, which flies to the north and becomes the first man made machine , which will be released in the interstellar space.

Scientists hope that the plutonium power source from Voyager 1, enough for at least five years of the study of interstellar space before it runs out.

"Every time we explore new, then open something completely unexpected," - said the scientist Voyager Project Officer, Rob Decker of the Applied Physics Laboratory at Johns Hopkins University in Maryland.

"We did not expect that will come on so far," - he said.

"When we first started, the space age began 20 years ago, and we had no evidence that cell phones can serve so long," - said Voyager project scientist at the California Institute of Technology, Ed Stone. "He is steadfast."

Voyager Project Team, presented his findings at the American Geophysical Union, held in San Francisco this week. Visit the news portal, argue, argue, prove.
