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 ...
The contrasts between these arguments are fully explored in the field of environmental ethics. Debates often focus on how much time and effort should be expended on investigating the possibility of any microscopic life on a planet before deciding whether to terraform, and what level of sophistication or chances for future development alien life would deserve varying levels of commitment to non ...
NASA's mission to return samples from Mars and potentially discover the first signs of alien life has a new timeline. The samples may arrive sooner. NASA scrapped its $11 billion scheme to grab ...
The study's authors found that perchlorate can destroy organics when heated and produce chloromethane and dichloromethane as byproduct, the identical chlorine compounds discovered by both Viking landers when they performed the same tests on Mars. Because perchlorate would have broken down any Martian organics, the question of whether Viking ...

A superhabitable world is a hypothetical type of planet or moon that is better suited than Earth for the emergence and evolution of life. The concept was introduced in a 2014 paper by René Heller and John Armstrong, in which they criticized the language used in the search for habitable exoplanets and proposed clarifications. [2]
