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]
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]
Astronomers studying Mimas, one of Saturn's smaller moons, say it's likely hiding a giant ocean beneath its crust.. Using data gathered from the Cassini probe, which studied Saturn and its moons ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
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.
Journey to Enceladus and Titan (JET) is an astrobiology mission concept to assess the habitability potential of Enceladus and Titan, moons of Saturn.. The JET orbiter concept was proposed in 2011 by the Jet Propulsion Laboratory to NASA's Discovery Program for its 13th mission, but it was not selected as a semi-finalist; Lucy was selected on January 4, 2017.
Proxima Centauri b, located about 4.2 light-years (1.3 parsecs) from Earth in the constellation of Centaurus, is the nearest known exoplanet, and is orbiting in the habitable zone of its star. [13] The HZ is also of particular interest to the emerging field of habitability of natural satellites , because planetary-mass moons in the HZ might ...
