Voyager 1, launched by the U.S. space agency in 1977, is set to become the first spacecraft to leave the solar system and start a new journey in outer space, experts say. National Aeronautics and Space Administration (NASA) scientists are intrigued by the recent increase in cosmic rays hitting the spacecraft, which for decades has taken images of the Earth and other planets in the solar system. The changes could mean that Voyager is “on the verge of a breakthrough 18 billion kilometers from Earth," NASA said. NASA described Voyager 1 and its companion voyager 2-now more than 14.7 billion kilometers away from the sun-as “the two most distant active representatives of humanity and its desire to explore."
