(Dallas) NASA’s Voyager 1 probe, the farthest spacecraft from Earth, is once again sending scientific data.

Voyager 1’s four instruments are back operational after a computer problem in November, a NASA space research center, the Jet Propulsion Laboratory, based in Southern California, announced this week. The team first received relevant information from Voyager 1 in April and recently asked it to start studying its environment again.

Launched in 1977, Voyager 1 travels through interstellar space, or the space between star systems. Before reaching this region, the probe discovered a thin ring around Jupiter and several moons of Saturn. Its instruments are designed to collect information about plasma waves, magnetic fields and particles.

Voyager 1 is more than 15 billion miles from Earth. Its twin Voyager 2, also in interstellar space, is more than 12 billion miles away.
