According to the reports, Voyager 1 has crossed into an area where the velocity of ionized gas (or plasma) that is emanating from the Sun has slowed to zero. This is said to be the final phase of the solar system exploration.
The Voyager 1 is one of the two spacecrafts that were launched to explore the planets of the outer solar system and the interplanetary environment. Their major objectives are to investigate the planet's atmosphere; characterize the satellites of the planets; provide improved values for the physical characteristics of the planet, its satellites, and any rings; and determine the magnetic field structure and characterize the composition and distribution of energetic trapped particles and plasma.
According to the Voyager scientists, they were not totally expecting that the twin spacecrafts will make it this far. Space exploration was still very new at that time, so there is no evidence that they can last that long in space. Still, they are hoping to have another 4 to 5 years for studies before their power sources is depleted.
