Day 7 to the landing!
Visit 'Mars' in Space.com's new 'Space Traveler' mini-documentary - Watch here! 🚀
And there is the problem. Sometimes I really hate them when they say "this planet was called by us superhabitable because of our standards". This is something I cannot allow, for me this is wrong. Thank you for understanding it!VS They would probably exclude methane rich atmosphere exoplanets until a living organism jumped up and bit them.
Ehmm, of course. This is something can't be described in a short message. I'm not blaming you or the guy whom you replied, but I think we can colonize it. I watched a video, and this time I luckly have the possibility to show you what is this (I saved it, on youtube). I don't know how to share a link, for this reason I do it in my way, the video is this:"I believe Mars may have once had life on it." Possible
"But i also don't think there's any now." Very probable
"i think we should begin terraforming." Useless and virtually impossible.
"It will be a long process." What makes you think the human race will last that long?
"Somehow or other , we have to add more air to Mars atmosphere." You are joking?
The rest? . . . . . . . . . . . . . . . . . .
I do admire your enthusiasm, but I believe you need to think it through more carefully.
Excuse me for my bad style but this is a topic very difficult to talk about for me...I really hope I wrote it correctly. In this documentary there are all the possible steps to terraform Mars. Maybe this doesn't seem possible, but if you try to imagine this, that isn't so hard. Firstly, we have to warm the planet, but we have to take in account the possibility to ruin it. Secondly, we have to achieve a quite good atmosphere, I mean thick. And besides that, you have to make the air "breathable". As the video shows (I know, this is very long but well made in my opinion) we can use those farms spreading greenhouse gases that make the atmosphere thicker and the planet warmer, two points figured out in one simple move, but outstanding I guess. I really don't know wheather the source is reliable, but since I'm interested in this topic I know something about it, and I can feel wheater something is correct or not, in other word, I think this documentary is trustable! I nearly forgot: the proces of "making the air breathable" is something so simple that I don't think I should talk about it...
This is something true. Colonisation of Mars is possible, but if don't terraform Mars, the only chance you have is that to live underground. Mars' underground is a place in which you can be warm and keep breathe as well as keep away from radiations. This seem to be a good solution for the beginning, but if you have to go in this way for one millennium I really don't thik that this is good. In other words, we must terraform Mars.Colonisation is quite different and very possible - eventually.
What do you mean? Now, you say that we can do it in a far future, then you say we couldn't even do it in a far future?Terraforming involves making the whole planet Earthlike, complete with atmosphere
Not in our lifetimes - if ever!
Anyways, maybe I didn't understand it correctly, something possible, so...Please be more precise...Terraforming - never in a million years.
Yes and yes. We are trying to do our better to don't warm our planet, althought we are burning it. We can warm Mars with atomic bombs, or however nucler explosions, the choise is large. The second question is more difficult to reply, and I have to find a solution with very few means, maybe we can bring gasses from Earth, or, we can take them from the inner layer of Earth if we cannot use Earth's atmosphere, I don't know exactly, but I know that in future this will be possible.Do you realise the amount of energy needed to warm a planet?
Do you realise the sheer weight of gas to provide an atmosphere?
As I have already said, we can use atomic bombs.. If we use them we figure out all the problems. The surface will be warmed as well as the atmosphere...And you have to heat - not only the atmosphere but the surface - which will be constantly in contact with the atmosphere
Here there is a problem. A very big problem. Anyways, heavy gasses can be the solutions, they would became part of the overall weight of the planet...Now, I really don't know. As far as I'm concerned to problem is too heavy for me. Many people appreciate in me the characteristic that when I understand the problem isn't something that I can solve, I acknowledge it, and this is what I want to do now. I gave you all the possible solution I could give, but now I acknowledge I'm not so clever to go on...Not only do you have to provide / move / from where? but you have to maintain a suitable breathable pressure, sufficient to prevent humans bursting on a planet which has lost such an atmosphere once due to insufficient gravity.
Of course, of course. You're right when you say I can't talk about atomic bombs. As the video I proposed says, if we sent bombs to Mars, we would make Mars gets more and more nake of atmosphere. If the problem was too much cold, we would figure this out with atomic bombs, but unlucky for me, this isn't the case. I want to apologise with you for this great mistake, I would have had to have the overall vision, but I didn't.Sorry, I repeat. You have no solution to offer. Atomic bombs? radiation. Check raw material availability to release, and maintain, that much energy.
I really don't think that this is important, but if you want to know that, I guess methane and carbon dioxide, as well as ozone, nitrous oxide and xenon and radom, but I'm not totally sure about the two last ones. I have no competences in gases and chemistry, and, as I usually say, let's let chemists do chemistry, my fields are Astronomy and Physics, even if I'm not very strong in both...heavier gases you propose (which are?).
To my (admittedly limited) knowledge, The gravity on Mars hasn't changed (significantly) since the planet formed. So if gravity didn't change, why did the Mars atmosphere change from the (theoretical) wet planet we believe it was to what it is now?Now we know that Mars gravity cannot retain an Earth-type atmosphere.
