“Today was a great day for Voyager 1,” said Linda Spilker, Voyager project scientist at JPL, in a statement Saturday. ... “Any references to the location of that code in other parts of the ...
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 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]
When Voyager 2 passed behind Saturn, viewed from Earth, it utilized its radio link to investigate Saturn's upper atmosphere, gathering data on both temperature and pressure. In the highest regions of the atmosphere, where the pressure was measured at 70 mbar (1.0 psi), [44] Voyager 2 recorded a temperature of 82 K (−191.2 °C; −312.1 °F).
The mission team successfully commanded Voyager 1 to revert to the X-band transmitter on November 7 and began collecting science data the week of November 18, and they are actively resetting the ...
NASA sent a radio signal to Voyager 2, located billions of miles away in interstellar space, and restored communications with the spacecraft after an errant command caused a blackout.
When Voyager 1 lifted off to space on September 5, 1977, no one expected that the probe would still be operating today. ... As Voyager 1 and its twin probe, Voyager 2, have aged, the mission team ...
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
