Well, Russia has said that they would have people on Mars by 2019, SpaceX 2024, and NASA in the 2030's. Now, unless we have another cold war fueled space race, I think we can count on Russia and NASA delaying such a mission. Even the SpaceX timeline is overly optimistic I fear but are most likely to forge ahead with their mission.
Possibility is there because Mars have atmosphere and traces of water. More research is needed and maybe it will take another 20-30 years to draw a conclusion.
I am not sure what to understand under term "colonize". Mars is a smaller planet than Earth, but it is still very huge object and pretty far away - and our present technology has difficulties even to land there by robots (though NASA is the best). So far there is no achievement to send a robotic probe that would be able to land there and return back to Earth... And we are ready to discuss about the colonization. What about "colonization", let's say, 10% of Sahara? We have lot of people for manpower, food, water supply, health care, good air to breathe, million tons of heavy construction equipment... If you mean to make "Mars habitable for humans" I am very skeptic, mother Nature is much-much stronger (will we make breathable atmosphere ? will we make artificial magnetic field to protect atmosphere against solar wind erosion?, etc...) Mars - perhaps for robots... For humans, top task is to save the Earth...
The first successful manned mission to Mars will probably be in the 2030's, although depending on how "successful" is defined, it might not be until the 2040's. Odds are that manned missions by any governmental agency will be sporadic, and strictly confined to exploration of future possibilities for the first 10 or 20 years. Private companies may be more aggressive, but are likely to pay for that by having a high percentage of fatal missions, which would probably bankrupt those companies; so although their projections are more optimistic, their actual results may be total failure.
Presuming that a majority of those sent to Mars in the first 20 years of manned exploration survive, there might be a permanent base of some sort within the next 50 years. But if a majority of those sent to Mars die, permanent bases may never be established, and certainly not within the next century.
Few days ago, Japanese space agency JAXA announced (http://mmx-news.isas.jaxa.jp/?p=1016&lang=en) it has greenlit a sample return mission to the Martian moon Phobos called the Martian Moons Exploration mission (MMX). If it’s successful, it could result in the first vehicle in the history of space travel that’s made it to the Martian system and back home, here, to Earth.
Dear Sara Thamer Hadi, Yes, in the context of growing global climate problems, pandemic, natural disasters, etc., the pressure on interplanetary colonialism in the future may increase. Best wishes,
When I read this question a parallel achievement arose. The bottom of oceans gives the 2/3rd of the Earth planet "near surface" region. And this belt has not been colonized since the times of submarines. Over the technological problems, there is another reason: man does not like the closed conditions. On the other hand there are the robots for this strict condition.
Well. robots can be useful but human kind still not suitable for long traveling under the cosmic radiation.
If the researchers can find a good radiation absorvant material... Then we can start thinking about the traveling too.
Other thing is the human body. Gravitation is important for a healthy body. In many sci-fi they shows a space ship with rotating parts where the people can stay for rest. This rotation simulates the 1G.
How can we build a ship like that ? Easy. On the Moon. From our small moon we can start the ships rockets with less effort, so it will cost less.
Yes, for several decades, conceptual projects of building cities at the bottom of the seas and oceans have been created. However, these investments would still be too expensive to implement. Perhaps the colonization of the bottom of the oceans on planet Earth will run in parallel with the colonization of the Moon and the planet Mars. It is the perspective of the next several dozen years.
Yes, the development of robotics will help in the colonization of the bottom of the seas and oceans on planet Earth, the colonization of the Moon, the planet Mars. however, it is still necessary to improve technologies that will allow people to live in these, however, significantly different and rather difficult conditions.
It is a perspectivic suggestion to follow the 3 "planetary colonozations" bottom of sea, Moon, Mars running parallel, because both can take suggestions from each other. All these events request some ten years intervals. and terrestrial bottom of the sea colonization gives tasks for nations with less economical capacities, than the greater: USA, China, Russia, India, Japan, Brasil, EU etc.
But till the human kind can not reach a level of thinking... There will be always a rift between the trials and succes.
The big countries should work together to reach this things.
Other thing is... The development need a lot of time. We dont really have too much left... Maybe I am wrong.. but still. The global warming... other negative happenings around the world... This things does not help this process,
Thank you for your answer and for taking part in the discussion. Thank you for confirming my theses. Yes, we need new technologies to implement these kinds of space expansion projects. The global problems of humanity on planet Earth, such as the advancing climate change and the global warming process, increase the importance of such projects.
You added an important point to our discussion. Yes, ongoing research and development projects are carried out in parallel in the field of prospects for increasing the possibilities of future colonization on the seabed, the moon and Mars. At the moment it is not decided which of these 3 development projects will become the leading ones. Besides, it is also not fully settled whether these large development projects will be carried out in the conditions of international competition or on the basis of international cooperation.
Dear @ Dariusz Prokopowicz The 3 great fields of "colonization" is different from the aspects of realization possibilities. Bottom of the seas are not so "theatral", but may be more useful, as field of resources. But robotics make it more "easily" realized. However, lunar and martian robotics is "open air" type, and it has goals for almost every years, and not only by one national space administrations. The recently running Chang'e 5 expedition exhibits an important step in this space competition.
Yes, I fully agree with your opinion regarding the potential possibilities and determinants of the colonization of the bottom of the seas and oceans on planet Earth, the colonization of the Moon and the planet Mars, and the differences between these different solutions to colonize such different environments. The interesting question that arises is: Which of these different environments will be colonized to a greater extent and faster? On the one hand, the key determinants that will determine this include technological progress and the results of cost-effectiveness analyzes resulting from the colonization of specific environments. On the other hand, if the growth rate of environmental pollution and greenhouse gas emissions continues to be high in the coming years, then perhaps in the XXII century the only salvation for humanity will be the colonization of other planets and possibly the colonization of the bottom of the seas and oceans after creating the necessary, further ecotechnologies (e.g. desalinating seawater and purifying this water from pollutants, energy storage, harvesting geothermal energy from under the bottom of seas and oceans, creating fully automated and robotic production processes in land areas, etc.).
Thaks for your Question. One important idea arise in connection with the Seefloor colonization. There shall be a good reason to repeat the Biosphere experiments. Those were both (I nad II) - as far as I know - interrupted because the bacterial ballances were not successfully constructed. However, the bottom of the sea gives a good new aim to these experiments far nearer than on Mars. Such Biosphere Domes will built in several new solutions, but mainly for terrestrial purpose, mainly mining, special industries, and also for human accomodations. But I think, the most amitious goal is to develop a working (closed) ecosystem, as it was planned for the Biosphere i. and II. Dome experiments.
Yes. I think the same. It will not be easy to recreate natural ecosystems under limited conditions in domes built on the seabed or on the surface of the planet Mars (much more difficult conditions). Natural ecosystems recreated in artificial conditions will probably not consist of thousands of different species of flora, fauna, fungi and microorganisms, just as in natural environments they will be rather "simplified", consisting of a smaller number of ecologically related species of various forms of living organisms. However, even in these deliberately limited, "simplified" ecosystems, efforts should be made to ensure that these artificially created natural ecosystems are as diverse, complex as possible, similar to their natural prototypes functioning in specific natural environments, and should also be characterized by a high level of sustainability.
According to the adopted plans, the first manned expeditions to Mars, which are to take place in the 1930s, will be a big, new step for humanity in the field of space exploration and perhaps also the first important step towards the colonization of Mars.
Even before the SARS-CoV-2 (Covid-19) coronavirus pandemic, NASA and the space agencies of some other countries reported that they planned to send a manned space mission to Mars during the 3-4 decade of this 21st century. However, in the meantime, the economic crisis of 2020 has emerged. Currently (2022), the economic downturn, high inflation, international trade wars, interrupted international supply logistics chains and electronic components sourcing and other negative economic phenomena that may lead to another economic crisis reappear. In view of these economic crises, can space exploration plans be postponed to a more distant future? Is a manned expedition to Mars planned for the 3rd decade of the 21st century still feasible in the context of the emergence of new economic crises? What do you think about it? What's your opinion on this topic?
Yes. The more mankind, through its activities, causes the loss of biodiversity of natural ecosystems, climate change, progressive global warming and fails to repair the damage done to the planet's biosphere and climate, the greater the scale of the future global climate crisis, the more difficult life on the planet will become, and the greater the importance of space exploration will grow, and the greater the resources will be allocated to man's attempt to leave our planet Earth.
