Space tourists threat?
Recently a team of American researchers said that the now popular space tourism can be dangerous for climate of the planet. However, many scientists refer to this statement with skepticism. My opinion on this subject the correspondent was expressed by one of the leading experts on space travel, Professor Alexander Bolonkin.
Recently the journal Geophysical Research Letters has accepted for publication an article in which a group of researchers suggests that the currently popular space tourism can be dangerous for climate of the planet. Although it is not yet printed, about this study already talking in many leading online publications. All of the authors of the publications seem to fully support the researchers ‘ view regarding the danger of space travel.
What a project to promote space so scared of scientists from the Aerospace Corporation in Los Angeles (USA)? The fact that, in their view, flying back and forth space “shuttles” are left in the upper atmosphere is a lot of soot, which is a product of incomplete combustion of nuclear fuel. A group of researchers led by Martin Ross built a computer model of such contamination, based on information from business plans for space tourism in ha by 2020, and emissions estimates developed spacecraft SpaceShipTwo company Virgin Galactic’s.
The model showed that 1000 annual launches of space “shuttles” eject from their nozzles about 600 tons of soot. Honestly, this is much less than what is left today in the atmosphere of airplanes and helicopters. However, according to the researchers, their soot “krasiwe” at fairly low altitudes, so any rain washes it from the atmosphere for several days or weeks. But spaceships “I think I” waste their higher air layers of the shell, i.e. the stratosphere, which is more than 40 kilometres above sea level. The snow and the rain there, you know, not go soot to clean up no one, so she can remain there for up to ten years.
High concentrations of soot in the upper atmosphere, according to Ross and his colleagues, can create quite a powerful greenhouse layer (similar to what allegedly creates CO2 in the lower layers of air mater), who will not miss the heat, leaving the planet’s surface. As a result, during the year the temperature at the poles of the Earth will increase about 0.2°C, which will lead to another round of “global warming”, the melting of ice in the Arctic and Antarctic, raising sea level and other horrors.
The researchers also suggest that a huge amount of soot can cause an increase in the amount of ozone in the atmosphere over the polar regions, which may also enhance the effect of “warming” (though many scholars honestly admit that I don’t know yet how the ozone may be associated with temperature increase on the planet).
So, the population of our planet has presented another gloomy apocalyptic forecast. However, many experts are of direct relevance to the design and creation of space ships, consider that the composed model is quite incorrect. For example, Jeff Greeson, CEO of XCOR Aerospace (Mahaw, USA), which develops such a “miracle” (though suborbital), noted that the assessment group the Ross amount of emitted soot is very unlikely.
“Data on emissions, which are, says Prison is likely to be relevant to the outdated spacecraft. As for modern “miracle”, the share of soot in the emissions is so low that it is even difficult to accurately measure.”
Also highly skeptical of this gloomy forecast is a former employee of NASA and scientific laboratories of the U.S. air force, member of the Board of Directors International space Agency, Professor Alexander Bolonkin . In an exclusive interview to the correspondent the scientist said, what, in his opinion, the true motives of this research:
“Another horror story that scare the authors of such researches and journalists, mentioning about him in several articles, akin to a horror story about the warming of the Earth from carbon dioxide CO2, which frighten the population, beaten out grants to study, tend to limit the industry of developed countries and receive the Nobel prize. The climate of the Earth completely depends on solar cycles, and how would we here on Earth nor puffed, we are not able with our current technology to influence it. Except to blow up all of humanity’s stockpile of nuclear bombs.
Assessment of climate change made by the authors, is very doubtful. In any case, the fine particulate matter from rocket engines space ships travel in flights will be negligible compared to emissions from modern aircraft flying in the stratosphere at a height of 9-11 kilometers, with emissions of thousands of tons of dust to a great height by the eruption of volcanoes (remember the recent volcanic eruption in Iceland and termination of aircraft flights in Europe) and from a powerful space rockets. I believe that the authors of scaring people is more of a speculative reasons and not because of real danger”.
With such conclusions it is difficult to disagree. Indeed, to get funding for research to prevent some catastrophe (even imaginary — remember how generously funded the research, devoted to solving the notorious “Problems-2000”) is easier than providing money for the development of new technology or fundamental scientific work. That is perhaps why we have already for several years, scaring a variety of upcoming Apocalypses — frightening the taxpayer will pay for any research program, including the crazy, if only scientists had pretended to save him from danger…
