To support an Earth-like atmosphere for about 4.6 billion years (Earth's current age), a moon with a Mars-like density is estimated to need at least 7% of Earth's mass. [20] One way to decrease loss from sputtering is for the moon to have a strong magnetic field of its own that can deflect stellar wind and radiation belts.
Oxygen from lunar regolith oxides can be a source for metabolic oxygen and rocket propellant oxidizer. Water ice can provide water for radiation shielding, life-support, oxygen and rocket propellant feedstock. Volatiles from permanently shadowed craters may provide methane (CH 4), ammonia (NH 3), carbon dioxide (CO 2) and carbon monoxide (CO). [10]
An absolute requirement for life is an energy source, and the notion of planetary habitability implies that many other geophysical, geochemical, and astrophysical criteria must be met before an astronomical body can support life.
NASA launched a spacecraft from Florida on Monday on a mission to examine whether Jupiter's moon Europa has conditions suitable to support life, with a focus on the large subsurface ocean believed ...
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.
In essence any maglev on the moon would behave similar to a vactrain without the need to provide an artificial vacuum. One significant difference with lunar trains is that the cars would need to be individually sealed and possess their own life support systems. [citation needed] For difficult areas, a flying vehicle may be more suitable.

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.
