The two most common reasons in favor of colonization are the survival of humans and life independent of Earth, making humans a multiplanetary species, [7] in the event of a planetary-scale disaster (natural or human-made), and the commercial use of space particularly for enabling a more sustainable expansion of human society through the ...
Colonization of Mars differs from the crewed Mars exploration missions currently pursued by public space agencies, as they aim to land humans for exploration. [6] [7]The terminology used to refer a potential human presence on Mars has been scrutinized since at least the 2010s, [4] with space colonization in general since the 1977, as by Carl Sagan, who preferred to refer to settlements in ...
A human mission to Mars, tens of millions of miles or km, is similarly challenging. [14] The Mars rover mission, for example, took 253 days to get to Mars. [14] Russia, China, and the European Space Agency ran an experiment, called MARS-500, between 2007 and 2011 to gauge the physical and psychological limitations of crewed space flight. [15]
Colonization of space was claimed by Stephen Hawking to be the best way to ensure the survival of humans as a species. [2] Other reasons for colonizing space include economic interests, long-term scientific research best carried out by humans as opposed to robotic probes, and sheer curiosity.
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, [1] and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be ...
Three experts told Insider about the scientific, medical, and ethical challenges of Elon Musk and Jeff Bezos' ambitions to colonize space
As early as 2007, Elon Musk publicly stated a personal goal of eventually enabling human exploration and settlement of Mars. [5] Subsequently, SpaceX has stated its goal is to colonize Mars to ensure the long-term survival of the human species, [6] proposing since the 2000s and early 2010s different concepts for reaching Mars, including space tugs.
The farthest humans have been beyond Earth is the Moon, under the U.S. National Aeronautics and Space Administration (NASA) Apollo program which ended in 1972. Conceptual proposals for missions that would involve human explorers started in the early 1950s, with planned missions typically being stated as taking place between 10 and 30 years from ...
