Apparatus had to work for about five years. But for almost half a century, invaluable data has been provided to the Earth.
NASA's Voyager 2 vehicle left the confines of the solar system and entered interstellar space. It is now about 120 astronomical units of the Earth
. It has become the second man-made object to leave the solar system. The first was his twin brother Voyager 1. Scientists hope they will benefit science for at least ten years. Correspondent.net tells the details.
Travelers, Great Achievements
The longest scientific mission in history began more than 40 years ago when two interplanetary NASA stations – Voyager 1 and 2 went to explore l & # 39; space. The device weighs 723 kg each.
The first aircraft launched by Voyager-2 is August 20, 1977. It remains the only aircraft to have visited the four giant planetary giants of the solar system: Jupiter, Saturn, Uranus and Neptune. At the same time, there were no other probes near Uranus and Neptune.
On September 5, 1977, NASA launched the Voyager 1 station. Initially, the station was intended for the study of Jupiter and Saturn. He became the first camera to take detailed photographs of the satellites of these planets.
It is thanks to Voyager's photographs that the Great Red Spot of Jupiter was a gigantic hurricane.

In 2012, Voyager 1 was the first in history to overtake the solar system. In 40 years, the device has moved away from Earth nearly 20 billion kilometers and has become the most distant artifact.

For the second time in the history of humanity, the device made by the man entered the interstellar medium on November 5th. It was the Voyager 2.
The outer limit of the heliosphere, called heliopause, is where the rarefied sun meets a cold, dense interstellar medium.
Voyager 2 is now 18 billion kilometers from Earth Signals are late with a delay of 16.5 hours. The information of the first Voyager is more than 19 hours. And this time, all the time grows up.

NASA scientists noted that the characters at the intersection of the heliopause trips were different. In the case of the second probe, it looked like a sharp drop in the recording rate of solar wind particles and the corresponding increase in the binding of galactic cosmic particle particles.
This is due to the fact that they came from the solar system in different places: one in the northern hemisphere, the other in the south. In addition, the difference in the solar cycle was reflected on them.
"Both devices are in perfect health, if you're talking about seniors, they're fine," they say in a mission.
Space vehicles are supplied with electricity from radioisotope thermoelectric generators and gradually lose power with the disintegration of available plutonium reserves.

The sources of radioactive isotopes being exhausted, scientists will have to disconnect certain instruments on board.
as well as detectors of charged particles and cosmic rays. Other devices, including cameras, are disabled due to failures or energy savings.
One of the last and most famous photographs of the Voyager 1 Pale Blue Dot was the February 1990 transmission. In this photo, the camera photographed the Earth at a distance of six billion kilometers, through which you can see the title of a newspaper at 800 meters altitude.

Communications with both devices are now supported by NASA's long-range space communications network, whose antennas are located in California, Madrid and Australia.
Note that users have been calculated five years of operation, but both devices have repeatedly exceeded all estimated terms.

The plate also contains the location of the Earth and the solar system in relation to 14 powerful pulsars (cosmic sources of powerful radiation) and a radiation pattern of the atom of hydrogen.
