Temperatures close to the freezing point of methane (90.4 K; −182.8 °C; −296.9 °F) could lead to both floating and sinking ice - that is, a hydrocarbon ice crust above the liquid and blocks of hydrocarbon ice on the bottom of the lake bed. The ice is predicted to rise to the surface again at the onset of spring before melting.
Titan receives just about 1% of the amount of sunlight Earth does. [1] The average surface temperature is about 90.6 K (-182.55 °C, or -296.59 °F). [2] At this temperature water ice has an extremely low vapor pressure, so the atmosphere is nearly free of water vapor.
Titan is the only object in the outer Solar System where a spacecraft has landed and conducted surface operations. The geology of Titan encompasses the geological characteristics of Titan, the largest moon of Saturn. Titan's density of 1.881 g/cm 3 indicates that it is roughly 40–60% rock by mass, with the rest being water ice and other ...
It is more than 400 km (249 mi) long and flows into Titan's second largest hydrocarbon sea, Ligeia Mare. [1] The surface of Titan is mostly water ice, so Vid Flumina is a river of methane and ethane flowing across and cutting canyons into ice as though it were bedrock.
Whether there is life on Titan, the largest moon of Saturn, is currently an open question and a topic of scientific assessment and research. Titan is far colder than Earth, but of all the places in the Solar System, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes, and seas on its surface.
The Titan Lake In-situ Sampling Propelled Explorer (TALISE) was a conceptual design study for a Spanish lander mission envisioned to splash down and navigate across Ligeia Mare. [17] In 2015, the NASA Innovative Advanced Concepts program (NIAC) awarded a Phase II grant [18] to a design study of a submarine to explore the seas of Titan. [19]
Jingpo Lacus is a lake in the north polar region of Titan, [1] the planet Saturn's largest moon. It and similarly sized Ontario Lacus [2] are the largest known bodies of liquid on Titan after the three maria (Kraken Mare, Ligeia Mare, and Punga Mare). [3] It is composed of liquid hydrocarbons (mainly methane and ethane).
Woytchugga Lacuna is one of the largest lakes of Titan.. It is located at 68°53′ N and 109°00′ W [1] on Titan's surface and at 449 km in length it is the longest Titanean lake and third longest body of a number of "hydro-carbon lakes" found on Saturn's largest moon". [2]
