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]
Voyager 1 and its twin send back science data continuously through the Deep Space Network, a system of radio antennae on Earth, with about six to eight hours of the probes’ detections returning ...
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).
Members of the Voyager flight team celebrate after receiving the first coherent data from Voyager 1 in five months at NASA's Jet Propulsion Laboratory on April 20.
Voyager 1 is currently the farthest spacecraft from Earth at about 15 billion miles (24 billion kilometers) away, while its twin Voyager 2 has traveled more than 12 billion miles (20 billion ...
As of November 2017 it has a distance from the Sun of about 140 astronomical units (AU) [10] (21 billion kilometers, or 0.002 light years), and it will not be overtaken by any other current craft. In August 2012, Voyager 1 became the first human-built spacecraft to enter interstellar space. Though declining, the onboard power source should keep ...
NASA's Voyager 1, the most distant spacecraft from Earth, is sending science data again. Voyager 1's four instruments are back in business after a computer problem in November, the Jet Propulsion ...
