Natural satellites that host life are common in (science-fictional) written works, films, television shows, video games, and other popular media. factual satellite, fictional life Europa, Callisto, Ganymede, Io and Titan in "Cowboy Bebop" (1998) The Moon in A Trip to the Moon (1903) and many other films; Europa in Europa Report (2013) and ...
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 possible origin of the lenticulae on Europa’s surface is the strong gravitational pull of Jupiter. [6] As the surface is stretched and squished, the surface may crack and pull apart, or be pushed together. Another potential origin of various chaos terrain on Europa is interactions between the icy surface and liquid ocean under Europa’s ...
He said he believes Mars' underground reservoirs could be harboring some form of life. " It's certainly true on Earth − deep, deep mines host life, the bottom of the ocean hosts life," he said.
Ahead of the spacecraft is a 1.8 billion-mile journey to Europa on a trajectory taking it past Mars and then Earth, using the planets’ gravity as a slingshot to add speed for the trek.
Conceivably, if life exists (or existed) on Mars, evidence of life could be found, or is best preserved, in the subsurface, away from present-day harsh surface conditions. [57] Present-day life on Mars, or its biosignatures, could occur kilometers below the surface, or in subsurface geothermal hot spots, or it could occur a few meters below the ...
An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.
Mars Exploration Program (MEP) is a long-term effort to explore the planet Mars, funded and led by NASA.Formed in 1993, MEP has made use of orbital spacecraft, landers, and Mars rovers to explore the possibilities of life on Mars, as well as the planet's climate and natural resources. [1]
