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 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]
Jupiter was in a more favorable position vis-à-vis Earth during the launch of Voyager 1 than during the launch of Voyager 2. [39] Voyager 1 's initial orbit had an aphelion of 8.9 AU (830 million mi), just a little short of Saturn's orbit of 9.5 AU (880 million mi). Voyager 2 ' s initial orbit had an aphelion of 6.2 AU (580 million mi), well ...
An enduring mystique surrounds the Voyager 1 and 2 probes. Launched two weeks apart in 1977, the twin probes changed the way we see our solar system, sending back stunningly detailed views of ...
A Titan/Centaur-6 launch vehicle carries NASA's Voyager 1 at the Kennedy Space Center on Sept. 5, 1977. (NASA) ... Voyager 1 and its twin, the Voyager 2 probe, each launched in 1977 on missions to ...
Voyager 1′s odyssey began in 1977, when the spacecraft and its twin, Voyager 2, were launched on a tour of the gas giant planets of the solar system.
In August and September, the two Voyager spacecraft to the outer planets were launched. Voyager 2, launched on 20 August, went on to fly past Jupiter, Saturn, Uranus and Neptune. Voyager 1, which was launched on 5 September, flew past Jupiter and Saturn, with a planned flyby of Pluto being cancelled in favour of a closer flyby of Titan. [1
Voyager 1 and its twin, Voyager 2, launched from Florida in 1977. By 1989, they had completed the first tour of the solar system. Each spacecraft exited the solar system years ago and has been ...
