Human presence in outer space began with the first launches of artificial object in the mid 20th century, and has increased to the point where Earth is orbited by a vast number of artificial objects and the far reaches of the Solar System have been visited and explored by a range of space probes.
The two most common reasons in favor of colonization are the survival of humans and life independent of Earth, making humans a multiplanetary species, [6] 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 ...
In recent years, there has been an increase in research on the issue of how humans can survive and work in space for extended and possibly indefinite periods of time. This question requires input from the physical and biological sciences and has now become the greatest challenge (other than funding) facing human space exploration. A fundamental ...
People living billions of miles from Earth will start feeling like their own people group. It won't look like the galaxy in Star Wars, or other sci-fi universes full of human-like alien races.
I think we had assumed the 50 years of research we had gotten from astronauts in the space stations orbiting Earth had told us everything we needed to know about how humans respond in gravity ...
Those under 50, who will have the most time to take advantage of emerging research, therapeutics, and interventions, can likely expect to live up to 100, says Dr. Evelyne Bischof, an internal ...
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.
In humans, this finely tuned resource balance grants us a maximum lifespan of about 120 years. But that doesn’t mean we can’t alter biology and intervene in these processes of aging, and maybe ...
