Voyager 2 has fulfilled its fate to leave the heliosphere and become the second interstellar spacecraft after Voyager 1, according a statement from NASA.
NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.
The Voyager 2 probe was launched on August 20, 1977, 16 days before Voyager 1, on a mission to explore Jupiter and Saturn. Voyager 2’s mission to explore the Solar System continued and it went on to become the first spacecraft to explore Uranus and Neptune. Ever since completing this part of its mission in 1989, the pair has been pointed towards deep space.
Voyager 2 has entered interstellar space by passing the heliosheath, the outermost layer of the Sun’s “magnetic bubble” beyond which the velocity of solar winds dramatically drop.
Voyager 2 is armed with Plasma Science (PLS) instrument so it’ll be able to beam back some invaluable information on the nature of the heliosheath and the interstellar medium outside the Solar System.
