Some studies suggest that the projected increase in space travel will damage the ozone layer. [6] [7] A single rocket launch produces 300 tonnes of carbon dioxide, staying longer in the upper atmosphere than emissions caused by airplanes or jets. [8] Thomas Fink, however, argues the long-term benefits of space science offset the ecological ...
The sum of human experience has resulted in the accumulation of 58 solar years in space and a much better understanding of how the human body adapts. In the future, industrialisation of space and exploration of inner and outer planets will require humans to endure longer and longer periods in space.
Since the early 1990s, research began on the salutogenic (or growth-enhancing) aspects of space travel. One study analyzed the published memoirs of 125 space travelers. [29] After returning from space, the subjects reported higher levels on categories of Universalism (i.e., greater appreciation for other people and nature), Spirituality, and Power.
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 ...
No extraterrestrial life has ever been discovered. But if extraterrestrial life exists, it may be vulnerable to interplanetary contamination by foreign microorganisms. Some extremophiles may be able to survive space travel to another planet, and foreign life could possibly be introduced by spacecraft from Earth. If possible, some believe this ...
The space station is whizzing around Earth at about five miles per second (18,000 mph), according to NASA. That means time moves slower for the astronauts relative to people on the surface. Now ...
That solution would take current Air National Guard units — nine of them, in six different states — and move them to the U.S. Space Force. The proposal is not without controversy.
The Drake Passage, between the southern tip of South America and Antarctic, is infamous as one of the most dangerous journeys on the planet. But why is it so rough – and how can you cross safely?
