Voyager 1 and the other probes that are in or on their way to interstellar space, except New Horizons. Voyager 1 transmitted audio signals generated by plasma waves from interstellar space. On September 12, 2013, NASA officially confirmed that Voyager 1 had reached the interstellar medium in August 2012 as previously observed. The generally ...
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).

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 ...
In 2012, Voyager 1 ventured beyond the solar system, becoming the first human-made object to enter interstellar space, or the space between stars. Voyager 2 followed suit in 2018. Voyager 2 ...
