Voyager 2 view of Enceladus in 1981: Samarkand Sulci vertical grooves (lower center); Ali Baba and Aladdin craters (upper left). Enceladus Life Finder (ELF) is a proposed astrobiology mission concept for a NASA spacecraft intended to assess the habitability of the internal aquatic ocean of Enceladus, which is Saturn's sixth-largest moon [1] [2] of at least 146 total moons, and seemingly ...
Thought to have a subsurface ocean maintained by geologic activity, tidal heating, and irradiation. [33] [34] The moon may have more water and oxygen than Earth and an oxygen exosphere. [35] Enceladus: Saturn: Enceladus – potential habitability: Thought to have a subsurface liquid water ocean due to tidal heating [36] or geothermal activity. [37]
One ocean is on the surface and consists of mainly liquid methane (CH 4) and ethane (C 2 H 6). The second ocean is under the surface and is made up of brine. Titan is a moon of Saturn but Titan is a large moon that is comparable in size to many planets. Titan is about the size of Mercury and about 40% the size of Earth.
A deep ocean exists beneath the icy, cratered surface of Saturn’s moon Mimas, according to a new analysis of data from NASA’s Cassini mission.
Investigate the habitability and potential for life in ocean worlds on both Enceladus and Titan Investigate Titan as an Earth-like world with an evolving climate and landscape. These goals would be accomplished by measuring the nature, abundance and isotopic properties of solid- and vapor-phase species in Enceladus' plume and Titan's upper ...
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain an environment hospitable to life. [1]
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 proposed spacecraft would enter into Saturn orbit and enable multiple flybys through Enceladus's icy plumes. After spending about two years in orbit as slow as 2 km/s around Saturn, [2] LIFE would use its propulsion system to escape Saturn and begin the ~4.5 year long voyage back to Earth with the collected particles in a return capsule.
