Scientific assessment of the possibility for humans to inhabit other planets in future
It seems to have been on the road for a very long time: the plans and efforts of science in the past always seemed to turn into realities in the future. Evidence has been too glaring, and to such an extent that it seems most scientific ideas always turn into realities.
Centuries ago, if one had lived in the midst of people who could hardly believe that one day humans would be able to travel through air (rather than land and sea which were the usual routes) to other countries and parts of the world in future, one would likely be less confident to talk about the possibility for mankind to travel to other planets and inhabit them.
In this age when science continues to understand and conquer the Earth, and concentrates more on other planets in our solar system, one would be more confident to talk about the possibility of exploring other planets and inhabiting them.
While this idea of travelling to other planets and inhabiting them sounds awesome and fantastic, it could be frowned upon by religious fanatics who look upon certain ideas and actions of mankind and science as either “impossible”, “weird”, “abominable”, or even “crazy”—this can be quite annoying, especially when most religious people who believe in GOD are well-informed about the extent to which anything is possible.
This brings to mind, one of the greatest statements to have ever been uttered by a great envoy of GOD: “For verily I say unto you, That ‘whosoever’ shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have ‘whatsoever’ he saith”—Jesus Christ.
Take note of the words “whosoever” and “whatsoever”—these words are boundless and not only applicable to those who belong to certain religious groups, or other types of belief systems.
On the other hand, the statement from the great envoy of GOD could prompt some big questions:
- did GOD create the universe and expect mankind to remain on the Earth, and be active only on it?
- can other parts of the solar system be used by mankind, just as the Earth has been used?
- would GOD approve of people being taken from Earth to other planets, stars, or solar systems?
- would it be an abomination for mankind to inhabit other planets—especially in the event that inhabiting other planets becomes reasonable and justifiable?
- would mankind be going beyond the limits destined for it if it inhabits other planets?
A recall of the first achievement in space exploration
Each good combination of science and technology has yielded a wonderful result: on July 20, 1969, at 03:00 hours, 56 minutes and 20 seconds, Central European Time, hundreds of millions of people witnessed 2 astronauts, Neil Alden Armstrong and Edwin E. Aldrin, become the first men to successfully set foot on the moon.
In my opinion, this is the most significant achievement in space science and travel because it astonished humanity, enlightened people about great possibilities, and inspired/led to other achievements that followed thereafter.
On the other hand, while mankind was excited about the successful flight to the moon, science was busy occupying itself with exploratory flights to planets such as Mars and Venus.
Venus had been undergoing investigation using unmanned sondes (equipment that send information about their environments) in the same vein that the successful landing on the moon began with investigations using unmanned satellites.
On May 18, 1969, Russia (Moscow) reported that after 130 days, the “Venus sonde 5” ended its journey; also, it covered a distance of 156.25 million miles, and carried weights that summed up to 2,260 pounds.
Have there been attempts to assess the suitability of other planets for human habitation?
Russian and American experiments were conducted in the past in order to assess the suitability of other planets for human habitation—how suitable other planets could be for human habitation.
Late Professors Carl Sagan (Harvard, U.S.A.) and Dmitry Martynov (Sternberg Institute, Russia) both did research work in similar/related areas. Their intention was to assess the suitability of Venus for human habitation, and conquer it.
During laboratory research, they acquired reconnaissance reports from the American Mariner and the Russian Venus sondes (equipment that provide information about their environments).
On 6 June, 1969, the Telegraph Agency of the Soviet Union (TASS) estimated that the surface temperature of Venus varies between 400ºC and 530ºC.
This estimate was almost the same with the one reported in 1967 from the “American Mariner V” which radioed/messaged back a temperature of 480ºC and atmospheric pressure between 50 bars and 70 bars—roughly the pressure that exists 900 meters (3000 feet) under water on Earth.
Russia received details from the sondes which made successful soft landings. Generally, information states that the atmosphere on Venus has carbon dioxide content between 93% and 97%, nitrogen between 2% and 5%, and oxygen between 0% and 4%—these data are highly valuable information.
Carl Sagan published his ideas in a scientific periodical that has the enviable and honorable reputation of publishing only research work that has been thoroughly examined.
What conditions would make it possible for humans to inhabit/live on Venus?
Before his death, Sagan believed that in the near future, space-craft could be used to release thousands of tons of blue algae into Venus’ atmosphere, and blow them towards Venus’ surface.
The advantage of using blue algae is that they stay alive at high temperatures and reduce high proportions of carbon dioxide by using their metabolism; because of their ability to continuously and steadily reduce carbon dioxide, surface temperatures would gradually fall below 100ºC.
Furthermore, with the aid of light and water, carbon dioxide could be transformed into oxygen; with temperature lowered below 100ºC, there would be enough water vapor in the atmosphere that could cause rain-fall and subsequent flooding. The availability of enough water (owing to the flood), in combination with light, oxygen and water would be able to support life.
With the Earth behaving more unnatural and fast becoming uncomfortable due to man-made activities which are spinning out of control, scientists would have been assessing the suitability of other planets, and the possibility for humans to inhabit them—especially if the unexpected is likely to occur.
Although habitation of other planets can be speeded up by more research and improvement of modern space technology, only distant future generations might witness humans inhabit other planets.
The past achievements of science and technology in space have proven that great possibilities lie ahead, and ongoing research will likely lead to success which could be greeted with negative reactions from religious communities and critics.
