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 second probe, now Voyager 2, followed the JSX trajectory, granting it the option to continue on to Uranus and Neptune. Upon Voyager 1 completing its main objectives at Saturn, Voyager 2 received a mission extension, enabling it to proceed to Uranus and Neptune. This allowed Voyager 2 to diverge from the originally planned JST trajectory. [17]

If undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius at a distance of 4.3 light-years. [5] Voyager 1 – launched in September 1977, flew past Jupiter in 1979 and Saturn in 1980, making a special close approach to Saturn's moon Titan. The probe passed the heliopause at 121 AU on August 25, 2012, to enter interstellar space ...
Voyager 2's image of the north pole of Iapetus taken on August 22, 1981, from a distance of 910,000 km (570,000 mi). The crater on the lower part along the terminator is Roland [48] Voyager 2 became the next probe to visit Saturn on August 22, 1981, and made its closest approach to Iapetus at a distance of 909,000 km (565,000 mi) [49].
Voyager 1 relays messages to NASA’s mission control team after losing contact due to a technical issue. ... Voyager 1 is now using a radio transmitter it hasn’t relied on since 1981 to stay in ...
Voyager 2 flew by Jupiter. [91] Saturn 5 August 1981 1447 days (3 yr, 11 mo, 17 d) Voyager 2 flew by Saturn. Uranus 24 January 1986 3080 days (8 yr, 5 mo, 5 d) Voyager 2 flew by Uranus and was the first spacecraft to visit it. Neptune 25 August 1989 4389 days (12 yr, 6 days) Voyager 2 flew by Neptune and was the first spacecraft to visit it ...
The flyby also changed the spacecraft's trajectory out from the plane of the Solar System which prevented Voyager 1 from completing the Planetary Grand Tour of Uranus, Neptune and Pluto. Almost a year later, in August 1981, Voyager 2 continued the study of the Saturn system. More close-up images of Saturn's moons were acquired, as well as ...
