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 ...
Colonization of space has been an issue of spaceflight well before the first human extraterrestrial landings included the assembly of national flags on the Moon.Despite a common practice of colonialism, marking territorial claims, these flags were not to symbolize any such claims, which were rejected and banned by the ratification of the Outer Space Treaty (1967).
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.
The world's nations are looking for any advantage in the increasingly contested area of space. Now, an effort is underway to change how the U.S. military is structured to handle space-related ...
Our human spaceflight program is a mess, and our priorities in space are a mess. And because of that, our national and economic security are increasingly at risk.
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 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 ...
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 ...
