Voyager 1 space probe was launched by NASA as part of the Voyager program
to study the outer Solar System. It was launched 16 days after its twin, Voyager
2. Having operated for 37 years, 11 months and 28 days, the spacecraft still communicates with the Deep Space Network to receive routine commands and
return data. As of this year, it is the farthest spacecraft from Earth.
