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 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 ...
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).
Together, the observations point to a rigid, mostly solid interior beneath Io’s surface, rather than a global magma ocean — solving a 45-year mystery started by Voyager 1’s observations.
Of the 10 science instruments Voyager 1 started its journey with, four are currently gathering data on its cosmic environment, and each year, the spacecraft loses more of its precious power supply.

NASA’s 46-year-old Voyager 1 spacecraft has experienced a computer glitch that prevents it from returning science data to Earth from the solar system’s outer reaches.
