Voyager 2 initial flew through the Photo voltaic Procedure, then began touring in interstellar area. So considerably, it has been the only spacecraft to visit four of the most distant planets in the Solar System at the identical time, and it has fully altered its thoughts about what not only by themselves but their moons search like as perfectly.
One of the largest surprises for researchers was geared up by Jupiter’s moon Io. “This was the 1st evidence that this is the most volcanically energetic system in the Solar Program, hundreds of situations a lot more active than Earth,” suggests Ed Stone, a scientist on the Voyager undertaking.
It is hard to consider the distances
Voyager 2 is not only the longest-lived probe ever released by humanity, it is also the second farthest from Earth, after its sister Voyager 2.
If we shrink the Photo voltaic System so that the Sunshine is the sizing of a pin, the Earth would be 50 % a meter away. The bigger planet Jupiter is consequently about two and a 50 percent meters away. Neptune, the most distant planet in the solar program, sixteen meters. And Voyager 2 alone would be seventy meters away on that scale.
“The Voyager probes are the 1st bodies that handed underneath the influence of the interstellar atmosphere and hence let us to analyze this environment specifically”, informs Michal Švanda of the Astronomical Institute of the Charles University and the Astronomical Institute of the Academy of Sciences of the Czech Republic.

The probe aboard also carries a message for prospective extraterrestrial seekers in the form of a gilded copper document. The protect serves as guidelines on how to reproduce the concept and as a map of the place the Solar Process is situated in the Milky Way. Potential seekers will therefore be ready to hear to a greeting in fifty-5 different languages (“Greetings, little ones of the world Earth”) or immerse on their own in listening to the musical functions of Wolfgang Amadeus Mozart or the bluesman Willie Johnson.
Voyager 2 was released from the United States into place in August 1977 and was followed by Voyager 1 in September of the same year, just about every of which flew in a unique way. The 2nd probe launched is transferring at a a lot quicker velocity and consequently remaining the Photo voltaic Method previously than its sister probe, in September 2013.
Voyager probes, the measurement of a little vehicle, are run by the energy of the gradual decay of plutonium. They will possible operate out of electrical power by the conclude of this decade and prevent speaking with Earth, but they will go on to fly into area for billions of years as the silent ambassadors of humanity.
