NASA’s Voyager 2 has become the second human made object in history to exit the Heliosphere (bubble created by solar winds).
Spacecraft Voyager 1, crossed this boundary in 2012.
The Voyager spacecraft are the third and fourth spacecraft to fly beyond all the planets in our solar system.
Voyager 2 is the only spacecraft to have visited all four gas giant planets — Jupiter, Saturn, Uranus, and Neptune.
The two probes, Voyager 1 and Voyager 2 have left the heliosphere, but have not yet left the solar system as they are not out of the sun’s gravitational field yet.
About the Mission
Voyager 2 was launched on August 20, 1977, and Voyager 1 was launched on September 5, 1977.
The spacecraft were built to last five years and conduct close-up studies of Jupiter and Saturn.
