Voyager 2 is the second spacecraft that reached interstellar space and a valuable source of information for researchers and astronomers.
The probes sent important information about the area where the medium created by the sun ends, and interstellar space begins. Data collected by the Voyager probes allows researchers to observe how the sun interacts with other objects which are present in our solar system.
It has been a year since Voyager 2 reached interstellar space. The probe went beyond the heliosphere, a bubble of particles and magnetic fields generated by the sun and situated at a large distance after Pluto.
Some researchers argued that solar winds would lose their power as they continue to travel through interstellar space, but this does not seem to be the case, according to researchers who analyzed data provided by Voyager 1 and 2.
Voyager 1 was released in 1977, with Voyager 2 being released in advance. Voyager 2 had spent 42 years traveling through space and surprised researchers when it managed to reach interstellar space. In the past, there was little information about the heliosphere.
In comparison to Voyager 1, the twin probe followed a trajectory that demanded more tie to reach Jupiter and Saturn but allowed it to reach Uranus and Neptune, being the only probe that managed to reach this planet.
After the planetary exploration mission was completed, the probe continued to float, moving towards the outer boundaries of the solar system. While the main goal of the probe was to reach and study the planets, which were mentioned above, NASA decided to mount a high-gain antenna that allows it to communicate with the Deep Space Network.
An array of three radioisotope thermoelectric generators, which includes pressed plutonium oxide spheres, powers the probe. It is estimated that the probe will remain active in the following years, and more data could be received in the future.
