Space

[Kapitan]

I have always been interested in space and space travel not to mention the planets, but im wondering several things as we get into the 2020's and want to get views from others.

First up there is the mathematical evedence to support a planet 9, apparently this would be a planet that is eTNOs and is orbitting around 250 times more distant than the distance between the earth to the sun, and the planet would be around 5-10 times the mass of earth with a 20,000 year orbit of our sun.
Some have suggested that infact theres no planet 9 but rather a black hole in place, in anycase which do you think is the most probable?

Human on Mars, our planet aligns with Mars every 24 months, i find it highly likely we will see a human on Mars in my life time (yes im excited i want to go myself) but do you think the current proposed 3 year long mission will work? i do think it would be a bit much with no infrastructure for the astronaughts.
I also have a feeling Elon Musks proposal of 1 million to Mars is a bit far fetched for 2100.

Another thing about mars is that the surface is very cold so do you think we could create a habitable planet? we know how to warm up a planet thats for sure we do it to our own but in a few hundred years could we create a atmosphere and change the Mars planet into one similar to earth ?

Cryogenic travel, well there was another proposul about cryogenically freezing humans to perform extremely long missions, i'm mixed on the idea because id like to live on earth a bit longer and i would probably be in old age when i got frozen which is no good in my view, the humans that would need to be frozen would need to be around thier 30's and in A1 health thats my view.

A trip to the ISS yes its high on my list but right now unaffordable, but with the ISS due to decommission in 2024 its highly likely for some time atleast that the space station will hold tourists, the question is how much money will each person spend to get there (im getting quotes of $55m USD)
Of course id love to go to the ISS but id also love to go to the Moon and Mars do you think by 2050 good ol Elon will have come up with something so we could travel to these two places?

These are some questions i ponder sometimes there are many more but id like to get to know your views on the subject and any questions you may have about space.

"You should become independent of the earth asap, when you look at which speed it all is being destroyed by its self-appointed masters."

"Planet 9" should have been discovered long ago, after all one can compute where its solar orbit should be, at least approximately. For what i see the orbits of the currently known planets or smaller objects have all been discovered and can be explained without the interference of another object ?

Mars can be colonised, but do you think humans will be able to do this without a war about territory? By technological aspects it could have been done earlier than 2010, but "priorities" .. (politics and military).
"Terraforming" is another thing and would take some centuries, provided scientists find out how to transform all kinds of matter into other chemical stuff.
There are several differing points of view regarding space and exploration. A lot say they are not interested in space and understanding the underlying science, since it does not have influence their daily life. Then there is religion and anxiety in a lot of science deniers.. I'd say if the right nova directs its gamma ray bursts towards Terra.. let's say if those uninterested prevail and have their say i would say humanity will die out.

Cryogenic travel is interesting, but i think there are creatures better suited than just of all humans. You would have to get some antifreeze into the last cell before cooling it to or below zero degrees Celsius becaus ice chrystals will destroy biogenic matter. Even if the cells survive that physically, it is not sure if a brain subjected to such procedure will ever "work" again after this.

Going to ISS? Yes, anytime, as to Mars.

Planet Nine is a hypothesis that got postulated to explain certain anomalies in the orbital behaviour of objects in the outer parts of the solar system. As a hypothetical construct, it does righ that, but AFAIK we have no material hints and evidences for a nineth planet'S existence. However, the Sumerians postulated the existence of a big stellar object beyond the orbits of the known planets, but it is not clear what they imagined this object to be like by nature and identity: a deity, a planet, a comet, an artifical object. However, they seem to have thought that it was ver yhuge, means: had plenty of mass. Nibiru has been object of many UFO-hunter's phantasies.

Human on Mars, our planet aligns with Mars every 24 months, i find it highly likely we will see a human on Mars in my life time (yes im excited i want to go myself) but do you think the current proposed 3 year long mission will work? i do think it would be a bit much with no infrastructure for the astronaughts.

When I was young, I was attracted by such ideas, today, I find them more scary. Its, by all what we know, a dead piece of desolate sand and rock. The idea to be the only man on it, these days only holds a strong feeling of isolation and loneliness for me. Most of the cosmos, if not all, is lifeless, desolate and compeltely desinterested in man, nevertheless space is extrneely hostile and lethal to any form of life. I take no longer any comfort from such adventure stories. It was not always like this, but now it is.

I do not believe anymore in man "colonizing" moons or planets in this solar system. A small handful of specialists living in tiny tin capsules and wearing space suits before leaving the house, is no "colonization", but just an individual survival experience. Also, we have no fail-safe technology. In fact, yur technology is extremely vulnerable, still.

As long as it is voluntary onkly, however, I will not stop anybody daring to try himself out on such a mission.

The movie by Ridley Scott, The Martian, I consider to be very unrealistic and HOPELESSLY overoptimistic and extremely technology-affine. Its a dream. Reality just waits to shatter it, if you provide it an opportunity. Murphy'S Law says that in principle everything that could happen, sooner or later will happen, if you give it the time needed. That may be true for the happy ends, too. But its also true for the accidents and tragedies. I do not want to find out.

Also, developments here on planet Earth imo speaks against it.

I also have a feeling Elon Musks proposal of 1 million to Mars is a bit far fetched for 2100.

A bit...? Completely!

Another thing about mars is that the surface is very cold so do you think we could create a habitable planet? we know how to warm up a planet thats for sure we do it to our own but in a few hundred years could we create a atmosphere and change the Mars planet into one similar to earth ?

I do not know if we could do it, but I am quite certain that we will not do it and succeed. I am a fundamental realist - means: pessimist - these days when it comes to the outlook for human civilization. And that civilisation is the precondition for survival and technological adventures olike what you talk aboiut here.

Cryogenic travel, well there was another proposul about cryogenically freezing humans to perform extremely long missions, i'm mixed on the idea because id like to live on earth a bit longer and i would probably be in old age when i got frozen which is no good in my view, the humans that would need to be frozen would need to be around thier 30's and in A1 health thats my view.

Yes. Daredeviling and adventure and conquest are for the young, the specialised and the strong. Old, weak people are ballast in such and endavour. A burden for the others. A risk to the mission.

A trip to the ISS yes its high on my list but right now unaffordable, but with the ISS due to decommission in 2024 its highly likely for some time atleast that the space station will hold tourists, the question is how much money will each person spend to get there (im getting quotes of $55m USD)

Short time tourism in orbit, even a small hotel-kind of destination on Moon, i could imagine. also robotic ressource mining on Moon. You may want to read Frank Schätzing's 1000 pages novel "Moon", it plays with this scenario in a crime story setting. A typical Schätzing, I tend to like his novels.

According to several space related science program I have seen throughout the years-There are astronomers, astrophysicist and other scientist who has an Space-related education, is convinced there is a high possibility for an extra planet out there-Planet 9.

So far these scientist and conspirators are correct...the could be a planet nine...well thereafter their attitude is going in different direction.

While these conspirators believe it's inhabited
The scientist say it's nothing but a rocky world.

The mind doesn't have the packages installed required to run an explanation of space, or time.

[Skybird]

If time even exists.

There is this queer alternative explanation that says there is no time passing at all, but just an infinite ammount of frozen moments that get followed through like the picture cards in a "Daumenkino" (flip-book?).

I do not laugh about this anymore since I realised long time ago that it is quite similiar to the expalnations of the hum,an consciousness in Buddhist psyhcologxy, and my own meditation experiences with kind of altered states of mind. When the flow of time came to standstill, and indeed their formed an idea of everything existing in just one moment, one mathematical, endlessly small point. Its impossible to catch it in words.

I do not believe anymore that the world is just of a structure and nature and essence as our senses and our constructing intellect seem to tell us. These concepts are crooks, and they run our daily life and help us to orientate ourselves in it like Newtonian physics help us to play the balls on the pool table. But like there is another level of physics infold in these - quantum physics - there might be a truer truth, an more inner essence of things and existence in what our senses seem to tell us. Or as I sometimes saids in the past: the key to discovering the outer space out there maybe is to discover and understand the inner space inside our mind. Because maybe outer space and inner mind are one and the same.


What sense would it then make to think in plural anymore...?

People will colonize Mars about the same as they do Antarctica.

[mapuc]

I made a timeline with a 50 years something between(I don't know the exact mathematic word for it)

This timeline has its start in 1957..the next something on the line is 2007. How far have we come from 1957 to 2007...next something on the timeline will be 2057...Where will we be in space exploration and spacecraft development, 100 years after Sputnik 1 ? 2107.....2157....could be added to the timeline..

Antartica with or without global warming?

[Rockstar]

After the ice melted in Antarctica most suitable land I think would be underwater anyway. Nothing left but mountain tops.

[Rockstar]

A manned mission to Mars by 2100 seems a reasonable goal too me. We're expecting NASA's Project Artemis to send people back to the moon in another three years. We're going to be setting up camp in the south polar region to exploit its resources which will allow us to sustain long term lunar deployments, develop fuel sources to propel vehicles to Mars and to learn more on the effects of deep space on the human body. We may not be around when we get to Mars. But we get to be part of the beginning of some exciting times on the moon. Getting to see that again gets me all tingly like

[Platapus]

Until we can learn to take care of this planet, it would be a crime to contaminate another planet with humans.

[Kapitan]

Id say we have already started to contaminate other planets considering the amount of probes we have deliberately crashed onto other planets surface especially mars.

Im also wondering if we would ever go back to venus, i know the Russian probe that made it to the surface in the 70's only lasted minuets but if we could build something to over come the temprature and pressure thats on the surface maybe we could use that as a study for what could happen on earth with a run away green house effect.
