NASA's 48-yr-old Voyager 2 spacecraft to function for another year

NASA has successfully extended the operational life of Voyager 2, the only spacecraft to have visited Uranus and Neptune, by another year. Nicknamed the 'Big Bang', the effort involved simultaneously turning off certain powered devices and substituting them with lower-power alternatives while keeping the spacecraft warm. Launched on August 20, 1977, the probe is now in interstellar space.
