- THE recent Voyager encounter established certain facts about Triton's atmosphere: the surface pressure is in the range 1.5–1.9 Pa (15–19 μbar)1; the surface temperature is 38±3K (ref. 2); molecular nitrogen is the dominant atmospheric constituent3; hazes and clouds are visible not only on the limb but also against the surface4; the wind in the southern hemisphere is to the northeast at low altitudes (as shown by streaks on the surface4) and to the west at high altitudes (as shown by geyser-like...

Aug 6, 2020 · Voyager 2’s observations exposed its icy surface, at equilibrium with a tenuous atmosphere, measuring a pressure of just 14 micro-bar (McKinnon and Kirk, 2014, In: Encyclopedia of the Solar System, pp. 861-881). Images showed a variety of morphologies consistent with recent geological activity.

Furthermore, data acquired during Voyager 2’s flyby showed a tenuous but extended nitrogen atmosphere (with minor contents of methane, possibly highly localised), exerting a surface pressure as low as 14 micro-bar (equivalent to 1/70,000th of the Earth’s atmospheric pressure) and ranging in temperature between 38 K (-235.15℃) close to ...
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).
Aug 26, 2019 · Despite Triton’s frigid -392o F surface temperature, Voyager’s images revealed evidence of geysers spewing dark material into the moon’s tenuous atmosphere that deposited back onto the surface. Voyager passed behind both Neptune and Triton, with instruments returning data about their atmospheres.
While Voyager 2 was behind Saturn, its radio beam penetrated the upper atmosphere, and measured temperature and density. Minimum temperatures of 82 Kelvins (-312 degrees Fahrenheit) were found at the 70-millibar level (surface pressure on Earth is 1,000 millibars).
Precise determinations of Triton’s diameter (2,700 km), density (2.1 g/cm 3), surface temperature (38 K), and surface pressure (14 microbars) were retrieved from Voyager 2 data. With an albedo of 0.76, Triton is among the brightest solar system bodies, and its surface temperature is the lowest ever measured.

Jul 27, 2021 · Neptune's moon Triton has been explored by just one spacecraft, Voyager 2, in 1989. Images revealed a unique geologically young surface with landforms not found anywhere else in the solar system (Smith et al. 1989). Plumes erupt from a surface with a temperature of just 38K (Conrath et al. 1989).
