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.
Artist's depiction of Pioneer 10, the first spacecraft to visit Jupiter. The exploration of Jupiter has been conducted via close observations by automated spacecraft.It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.
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]
Searching for the ingredients for life on Europa will be a challenge for NASA's Europa Clipper spacecraft. Surviving the high radiation of the icy moon will be even harder.
NASA is set to launch a spacecraft to Jupiter's moon Europa, considered one of our solar system's most promising spots to search for life beyond Earth, to learn whether this ice-encased world ...
The spacecraft must travel 1.8 billion miles to get to Jupiter, getting a boost from Mars' gravity along the way. It's scheduled to arrive in April 2030. A 7-body problem and unfathomable radiation
Jupiter: Callisto – potential habitability: Thought to have a subsurface ocean heated by tidal forces. [41] [42] Ganymede: Jupiter: Ganymede – Subsurface oceans: Thought to have a magnetic field, with ice and subterranean oceans stacked up in several layers, with salty water as a second layer on top of the rocky iron core.

Jupiter is usually the fourth-brightest object in the sky (after the Sun, the Moon, and Venus), [102] although at opposition Mars can appear brighter than Jupiter. Depending on Jupiter's position with respect to the Earth, it can vary in visual magnitude from as bright as −2.94 at opposition down to −1.66 during conjunction with the Sun ...
