American research probe Voyager 2 became the second spacecraft in history that went beyond the heliosphere, and ended up in interstellar space.
On December 10 reported the press service of the space Agency NASA.
Voyager 2 took off in 1977 to study the Solar system. According to a former employee of NASA’s ed stone, chose him for “the Big trip”: to Jupiter, Saturn, Uranus and Neptune.
After 1989 began the so-called “interstellar mission” Voyager.

The heliosphere is like a bubble, which is composed of solar wind plasma. Beyond its border, is known as heliopause, interstellar space begins. Formally, the edge of the Solar system begins only in the hypothetical Oort cloud away from the Sun approximately a light year. To get to the Oort cloud, the spacecraft would take about 300 years.
Voyager 1 went out of heliopause in 2012. He became the first human-made object that is left in interstellar space. It also launched in 1977, but the route of the first probe was shorter: he flew around Saturn and Jupiter. Then Voyager 1 went to the border of the heliosphere.
On Board both probes is the “gold plates”. They marked the coordinates of the Solar system and Earth. Also on the discs recorded with the audio and video signals that can help the alleged aliens learning about the culture of earthlings.
Recall, the Mars probe InSight sent a new selfie. These images will help the mission team select the optimal locations for installing scientific instruments.
