flag NASA shuts off two instruments on Voyager 1 and 2 to save power, extending their deep space missions.

flag NASA is shutting down two science instruments on the Voyager 1 and 2 spacecraft to conserve power and extend their missions. flag The Voyagers, launched in 1977, are now in interstellar space, with Voyager 1 over 15 billion miles from Earth and Voyager 2 over 13 billion miles away. flag Each spacecraft still has three instruments to study the sun’s protective bubble and the space beyond. flag Turning off the instruments is necessary as the probes lose about 4 watts of power per year.
