The Voyager 1 spacecraft is functioning normally again after the aging probe’s dwindling power supply triggered a communications blackout. ... the science that Voyager is doing now is really ...
As Voyager 1 and its twin probe, Voyager 2, have aged, the mission team has slowly turned off nonessential systems on both spacecraft to conserve power, including heaters.
Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which was known to be quite large and to possess a dense atmosphere. This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. [22]
In 2013 Voyager 1 was exiting the Solar System at a speed of about 3.6 AU (330 million mi; 540 million km) per year, which is 61,602 km/h, 4.83 times the diameter of Earth (12,742 km) per hour; whereas Voyager 2 is going slower, leaving the Solar System at 3.3 AU (310 million mi; 490 million km) per year.

Voyager 2, which is operating normally, has traveled more than 12.6 billion miles (20.3 billion kilometers) from our planet. Over time, both spacecraft have encountered unexpected issues and ...
Although other probes were launched first, Voyager 1 has achieved a higher speed and overtaken all others. Voyager 1 overtook Voyager 2 a few months after launch, on December 19, 1977. [12] It overtook Pioneer 11 in 1981, [13] and then Pioneer 10—becoming the probe farthest from the Sun—on February 17, 1998. [14]
The spacecraft is currently about 15 billion miles (24 billion kilometers) away from Earth, while its sister vehicle, Voyager 2, has traveled more than 12 billion miles (20 billion kilometers ...
It left the heliosphere and crossed into interstellar space in December 2018. As with Voyager 1, scientists are now using Voyager 2 to learn what the Solar System is like beyond the heliosphere. Launched: 20 August 1977; Destination: Jupiter, Saturn, Uranus, Neptune; Arrival: 9 July 1979; Institution: NASA; Primary mission completion: August 1989
