In 2008, when Voyager 2 reached the edge 18 billion kilometers away, it found a 40000 degree "wall of fire" that Voyager 1 had not found before, tightly surrounding the solar system to form a space. Scientists analyze that this "fire wall" is the result of the "collision" between solar wind particles and external interstellar radiation particles. According to the relevant information about the "Fire Wall" received from Voyager 2 in 2018, its density is particularly low, so it is not harmful to Voyager 2.
Do the current achievements of Voyager 1 and Voyager 2 prove that human beings can successfully fly out of the solar system and escape from the "cage"? Actually not. Voyager 1 and Voyager 2 successfully broke through the solar system and the edge of the solar system caused by our above-mentioned "fire wall", only in terms of the distance that the solar wind particles can reach. The recognized radius of the solar system is 2 light years. At the speed of Voyager 1 and Voyager 2, it will take 20000 years to really break through this distance, but this is unrealistic. So far, the exploration time of both satellites in the air has reached 44 years, and they will be retired around 2030.

Voyager: Out of the Solar System

This is the end of an era. After 35 years away from Earth, the Voyager probe is finally about to fly away from the solar system. This fascinating documentary is based on eye-catching footage and image data from NASA and BBC archives, and examines the major discovery of this spaceship that has a profound impact on our understanding of the universe. The Voyager probe rushes out of the solar system tells an incredible story. The Voyager probe was supposed to last only five years, but it is still in operation today, as well as two small probes that have completely changed our understanding of the solar system. This film comes from the contributions of scientists who have worked for or been inspired by Voyager, evaluates the achievements of this space mission, and explores what will happen in the future.
