Re: Space exploration - The How and Why

"There is a good chance that generations prior, our generation, and our children's generation, will be condemned by historians as wasting the boom we've experienced due to cheap energy (oil) on wars and porns.  Is this is the legacy you want to leave?"

See, here is the problem with this idea that I actually see. You keep saying that we should be putting our resources into space exploration, but firstly where would we go? And secondly why would we go?

--Where would we go?--

Lets for the moment say that we are going to colonise our own solar system first (I think that is a fair assumption). Now, I am going to rule out the planets/moons that are just physically impossible to go to regardless of technilogical advances, at least in the short term. Mercury, too damn hot. Venus, too damn hot also. The moon, we will get to this one later. Mars, the lack of a magnetosphere makes any kind of terraforming pointless, so any colonisation would be small stations (will cover this further in the "why" section). Jupiter and Saturn's moons could also be candidates, but beyond that, everything else is just too damn cold.

--How--

Another problem would be what kind of energy source do you use? Solar, as you move further away from the sun, Solar will become less and less effective, and any other form of energy requires replenishment of the power source (nuclear needs uranium/thorium as well as a refinement procedure, combustion power sources need coal or gas, etc). So where would you be getting these sources of energy from? "We will invent such sources" is nothing more than a dream at the moment unless you are sitting on scientific breakthroughs that will change the world? No? The thing is, there are people working on these solutions, and are often out of necessity not a drive forward. I digress a little bit, so lets for the moment say that we are able to replenish fuel sources in the solar system en route, from asteroids, planets, etc. This still only limits our space exploration to the solar system. To reach out further, you need a power source that takes up very little space, is virtually inexhaustable, and potentially offers more power output than current energy sources. Something like that has its own advantages here on Earth without even thinking space exploration. Furthermore, we can have a look at the more advanced power productions, and we find that energy sources also create an interest in the military sphere, fission/fusion energy sources for example (http://en.wikipedia.org/wiki/Nuclear_fusion). Furthermore, we can still see money and resources being invested to develop new sources of power (http://www.theaustralian.com.au/news/nation/australia-urged-to-warm-to-fusion-reactor/story-e6frg6nf-1111112353368 and also here is the project website: http://www.iter.org/) which again still won't help in space exploration since it still requires a source for energy. So anything outside of our solar system is actually going to need a breakthrough or complete redevelopment of the worlds scientific understanding.

--Why--

So now we have established where we can explore due to limitations of our understanding (not just funding), we look at the reasons why. It will not be in search of a more sustainable environment, simply because one does not exist in our solar system, and furthermore one cannot be artificially created, so it will be in search of resources. Now, we look at potential sources of minerals. As far as I am aware, the moon has nothing of any real significance, so we are looking at Mars, maybe some moons of Jupiter or Saturn, and the asteroid belt. Now the asteroid belt is a different story, since it would possibly be more energy efficient to divert asteroids to an orbit around earth and mine them there, so it really only needs an expansion of current operations (the International Space Station for example), so we are left with just the moons and Mars. You are then suggesting that we put all our resources to pushing towards those destinations in order to send the resources back to Earth, and this is going to help everyone how? From what I can see, it will inflate costs (since the investment to mine and transport has just increased considerably). Which really leaves only one option that I can think of, and that stems from a need to search for alternative sources of resources. Currently, there are enough sources of minerals in the world, and I do not disagree that there is only a finite source of these minerals, but the need to look to other bodies in the solar system for resources is only based on a need that will only come about through the scarcity of resources on Earth. So essentially what you are fighting as the reasons that we haven't looked to our heavanly bodies more, is actually going to be the driving force of actually colonising space.

I give your invention the worst score imaginable. An A minus MINUS!

To hot, to cold

Graphene on the exterior would create a safe haven for any artificial structure. While living inside a bldg for life, and having to have buildings be made, then attached to the 'city' then cleansed before it could be used... That is how you live on hostile planets.

So Venus to Pluto is possible.

However there is one factor we may need.


Gravity.

Bone depletion, eye damage, and more are reported from longterm weightlessness. Studies have not been able to be done about less than Earth Gravity, but the presumption is that to low and you have problems. This may negate a colony on the moon, but allow a colony on Mars and Venus (No way Mercury, even Graphene would have issues there!)

Re: Space exploration - The How and Why

Wornstrum if I am correct in saying so, he mentioned colonization as in settling the place as well. Not just for resources. But very good points on the energy side so I will leave that alone.

Now keep in mind that he is one of the people moaning and complaining about how much a cd costs (due to its manufacturing, packaging, shipping, etc).

So lets assume the we spend the billions (possibly trillions) of dollars to actually make the moon or mars inhabitable for people. Now we have to feed and water those people at a bare minimum. Then comes all the other amenities like clothing, hygiene supplies, educational supplies, entertainment supplies, and a whole host of other items that these people living on another "world" are still going to have expectations of.

My father is a truck driver so I can tell you that currently the cost of shipping dairy goods from PA to AZ is right around 2076 miles approximately depending on the exact locations to/from. Now the average trucker makes 30.3 cents per mile (my dad being a owner/operator makes more than that but it wont effect the point I am making) so you multiply the miles by the amount and you get 629.08 for just the travel portion. Now, the trucking company has to pay for its employees gas as well so we have to factor that cost in. 2076 miles into gallons is 260 gallons (at around 8mpg). Seeing as the majority of trucks have a large enough gas tank to only fuel up once for that trip we can just assume that the cost to fuel him up in PA will be 4.32 to fuel up at the Pilot Flying J. That makes 260 gallons of diesel fuel turn into 1,123.2 dollars now. So far this trip has cost the company 1,752.28 dollars for just that ONE trip. This doesn't account for what they are making for the trip!

Now a company generally will average 3,000 dollars per month on each driver. Assume that the driver does 2 trips a week and that turns into a total of 8. So the profit margin there is 30% without calculating what the company has to pay in road taxes and a whole host of other issues which will effectively drop it down to about 10% roughly.

That is just 1 driver taking a load of 25,000 lbs of stuff from PA to AZ.

The average person eats 1,095 lbs of food per year so lets just say we start with a small number for testing purposes on the moon and we move....30 people there. Now we have a total of 32,850 lbs of food needed for those people (just food, doesn't include water or anything else). The cost to transport that in the United States (distance is not actually realistic for this) would be 238857 miles turning into 1,104,235.24 dollars (factoring cents per mile and diesel fuel). Now we both know that an astronaut is going to get paid more than a truck driver, and we also know that rocket fuel is more expensive than diesel so we are talking LOW END prices here!

Basically the point I am making is the inflation cost of a product being shipped to the moon is going to be roughly 66,000% making a $1 candy bar turn into $661 for it.

Now to the real point...how are those people going to pay for it? They aren't! How is the government going to afford it? They aren't! You cannot expect normal citizens to eat the same things an astronaut does for the rest of their lives.

Therefore, based on the above statistics, space colonization is not a feasible solution.



EDIT~~ All shipping costs vary as some companies even pay truckers pick up/drop off fees as well. And it does not include any maintenance issues on the trucks.

Re: Space exploration - The How and Why

Strange to discuss this topic in IC forums.^^

Since mankind started the cultural evolution about 25.000 years ago (sorry only german sources: Gerhard Schurz, Evolution in Natur und Kultur, 2011; Jochen Oehler, Der Mensch - Evolution, Natur und Kultur, 2010) humanity changed faster and faster. Today the cultural evolution is up to 10.000 times faster than biological evolution (if you do not believe in Darwin, go back to your cave now). It is only a matter of time when humanity will colonize space.

The "How" is not so important. Give it some time and private money, up we go. Our cultural evolution accelerates every day. The developments in the past 50 years is proof enough. In recent times private companies developed primitive "space-crafts", maybe this will later be called the start for the race to the stars.

The "Why" is much more important. The world economy produces some very rich people with special needs. James Cameron dived to the deepest point in the oceans. Others try to reach lower space or alike. In a few decades these ambitions will have reached the moon and beyond. A real breakthrough would be the discovery of basic life forms e. g. on the moons Titan or Enceladus. This will cause a "run" for aliens. Best would be an earth like planet "close" to our planet. 
It is not the need for new resources. There is no oil in the solar system, except on earth. For other minerals we can mine the oceans first. There is enough for at least 100 years to come.

So Venus to Pluto is possible.


Venus would still have possible issues with environmental damage to the infrasture (acid rain for example). Also, the air pressure on Venus is quite high I believe. Furthermore, Jupiter and Saturn are both gas giants, with rather high gravity from what I remember, so I think both of these planets are out.

Well, I did think of protective sheilding, but does graphene stop all heat disapation? It would need to retain most of the heat, and with that, it would need to be strong enough to handle large temperature differences (which when you look at glass, the thicker the glass, the easier it is to crack under different temperature extremes. This is because glass doesn't transfer heat as quickly, so the hot side expands, whilst the cold side shrinks causing the glass to break). So it would need to retain heat, whilst being strong enough not handle temperature differences (so I would imagine the cost of a settlement would be higher from placing graphene sheets through wear and tear). Furthermore, if we have look at the weather conditions on Nepture, we notice rather high winds forming (and we are talking a lot stronger than that of a hurricane, and how much infrastructure is often destroyed from a hurricane/cyclone each year?) (http://en.wikipedia.org/wiki/Neptune). Also Pluto was declassified as a planet, not that it matters in this discussion, because all objects in the solar system are considerable choices, so we should also include all the other bits of rocks floating out there (there have been a few dwarf planets discovered beyond Pluto). Even if you can handle the control of temperature, I think there are other factors still proventing us from colonising these planets, such as, gravity, atmosphere pressure (Neptune and Venus both are quite high, for example). If we are talking about colonising these areas, I think deep sea exploration and mining will be explored more before we even consider the extremes of Pluto or Venus (with more obvious choices elsewhere in the solar system), so again the need still stops us still.

"Wornstrum if I am correct in saying so, he mentioned colonization as in settling the place as well. Not just for resources."

I was trying to explain the reasons why we would look to colonise space. We generally colonise through needs on Earth, a perfect example are abandon mining towns (once the mining runs out). Furthermore, and we are going back a bit, areas were colonised that were at least to some degree self-sustainable (which is the reason Australia was ignored by explorers for so long, and there are records of explorers reaching it and describing it as a baron wasteland). Since transportation was long, self-sustainability to some degree was a must, and the same principle would apply to colonised areas in space, at least for a period of time. Again, there would be a need to colonise these areas first and foremost, and like most colonies on Earth, was based on needs (so more than likely resources of some kind...whether it be minerals, gas, space, agriculture, etc).

Re: Space exploration - The How and Why

Oh I was not arguing against you Wornstrum. Everytime exploration/colonization has been done in the past it was due to needs driving it. America was the need to be free from religious oppression...and so on.

I was just showing a different side of the argument so that he cannot simply say "the need is there so we must do it". When he simply has to understand that we can not afford to do such an endeavor at this time.

Its possible that in the future (not near) that we will have the technology to do so, but that is stuff already being worked on anyways.

Re: Space exploration - The How and Why

Oooops, I didn't see your post Firewing...

This was all based on repeated comments by xeno regarding the lack of momentum to move towards the stars:

"The "How" is not so important. Give it some time and private money, up we go. Our cultural evolution accelerates every day. The developments in the past 50 years is proof enough."

I do not disagree, I think that we will reach Mars in my lifetime. I was just pointing out current limitations that exist to explain why throwing resources into space exploration would just be a waste of time and money now. The how was to demonstrate that limitations exist that we do not have the current know how to solve, and these sorts of solutions would have a benefit on Earth, so it is more than just a lack of resources that has "prevented" such innovations.

"The "Why" is much more important. The world economy produces some very rich people with special needs."

James Cameron diving to the deepest part of the ocean for excitment/research is a bit different than take colonising space. James Cameron did not take a whole settlement down to the deepest part and establish a city down there, and the same can be said about rich people travelling to the moon. They are not taking a whole colony with them. If they decided to though, as mentioned about transport costs, the colony would be self-sustainable to some degree, or it would need some sort of output in order to constantly afford incoming goods. I cannot see rich people giving up everything to move to the moon and become a farmer, so the only option I could see is them taking poorer people with them (not entirely implausable actually). I still think the forementioned comment about an output of some kind would still be the driving factor of colonising (it would need some sort of economy), and I think it would need to be supply of some kind of resource (mining, labour [although I can't see how this would be cheaper than Earth-side options], agriculture, land, etc].

Having said that, rich people travelling to these areas could start the "tourist" economy that invests more money into the industry of space travel, but again, still meets my criteria of need (demands from rich people) and the colony offering some kind of resource (tourism).

"It is not the need for new resources. There is no oil in the solar system, except on earth. For other minerals we can mine the oceans first. There is enough for at least 100 years to come."

Yep, that was the point I was trying to make, is that because there is no need to do it, this is why we haven't pushed hard for it.

"A real breakthrough would be the discovery of basic life forms e. g. on the moons Titan or Enceladus. This will cause a "run" for aliens. Best would be an earth like planet "close" to our planet."

Well this I agree with, just look at the missions to Mars (discover water or life tongue), and I believe life on Mars hasn't been completely ruled out. As for the planet "close" to our planet, I do not think there would be anything close enough for a direct push in space exploration, since it would be far enough away that it would take decades to reach (and we are still talking close to our solar system). Still think the solar system would be first to explore in any case.

One thing I did forget, is possible research stations, and this would be funded directly governments, but again what is there to research that satellites, probes, drones cannot accomplish at less expense?

Re: Space exploration - The How and Why

I'll have a bigger post later, but I just want to put this out here:

Economics would not necessarily be the only reason for colonization.  The most important social justification is for the purpose of having a Noah's Ark.  Essentially, if a war, mass disease, asteroid, or some other planet-wide disaster occurred on Earth, a colony in space would allow biological samples to remain intact, possibly for a future repopulation.


That being said, if we can agree that this is a good goal even if there is no economic reason for space colonization, the economic question should become "how much are we willing to subsidize a colony for the purpose of having a lifeboat?"

EDIT: Actually, though, if we assume a colony would achieve all the ends the current space program achieves, we could consider at least NASA and the ESA budgets as baselines for how much a society is willing to spend, and a cost which would be spent anyway in space, so there wouldn't be THAT big a tradeoff.

What does NASA hope to acheive through its space exploration program? It was based off the Cold War, and sending man to the moon was a political stunt not one for science (as far as I understand).

Well... how much dependence would the colony have on Earth?

It may be possible to grow food in space (I believe the MIR space station was experimenting with hydroponic farms).  Oxygen can be recycled, either mechanically or via a hydroponic farm system.  Energy can be gathered via solar power.  If we use a location which has natural resources like minerals, mining operations may allow the colony to make repairs on itself.  So... aside from rare metals (which can be stored in bulk during the initial operation), is there a continual need for supplies?


But anyway, assuming the colony is self-sustaining, the lifeboat function would be pretty simple: if an asteroid killed all life on earth, the lifeboat population would remain in space until the environmental conditions on Earth settled down (I believe it took 1-2 years for the cloud creation from the K-T asteroid to finally go away).  Once the environmental conditions adjust, the lifeboat population could then return to earth on a hospitable yet near-vacant planet (ideally including some animal and plant biological specimens, if possible).


As for the possible earth-based alternatives, I do note one important problem with those.  Let's take a theoretical example: the US builds a bunker to sustain its population for two years.  WARNING: This may seem silly.  tongue

Now... pretend you're the Russian government.  You hear that the United States is unilaterally constructing a way its population can survive any global catastrophe, including a nuclear war, then repopulate the planet with Americans, putting picket fences and families of 2.2 kids in every country.  Know what that means?  The US just found a way to get around "mutually assured destruction," because even if the Russians destroy every US city and contaminate the planet with radiation, the domestic lifeboat would still be available.  So it's actually in the interests of the Russians to prepare for, then attempt, a nuclear first strike against the United States before the lifeboat can be constructed, because the alternative is that the US can first strike the Russians and, even if every American city is turned into a crater, the Americans would still "win" the nuclear war.

Why does that not apply to a space colony?  There's a couple reasons.  First, a space colony is likely to be more vulnerable to a nuclear response.  If the Russians and Americans ever did get into a nuclear confrontation, the Russians could easily nuke a colony.  Second, a space colony can be made as an international effort, whereas a domestic colony will always carry political bias behind it, if for no other reason than because a colony is restricted to a geographic region.


"This also comes down to a NEED, and I do not agree that this endeavour would really spark the need for a colony in space (don't they have people frozen in liquid nitrogen for that? tongue)"

Now you're not debating a question of "is a colony good."  You're debating a question of "will it happen."  Considering that "will it happen" is a function of "is a colony good," it's disingenuous to assume it won't happen until after we've gone through the good/bad debate.




"EDIT: Actually, though, if we assume a colony would achieve all the ends the current space program achieves, we could consider at least NASA and the ESA budgets as baselines for how much a society is willing to spend, and a cost which would be spent anyway in space, so there wouldn't be THAT big a tradeoff."

Well, there's always an inherent purpose in adventurism (to do something just to show that it can be done).  But then again, that particular period in time did have another non-scientific purpose in that we see the 60's/70's had a huge jump in the number of students entering math/science majors... tech boom!


But anyway... I was just noting here that NASA could be replaced with the space colony program.  So if you think NASA is useless, that only adds to the justification to redirect their funding toward a lifeboat.  tongue

Re: Space exploration - The How and Why

Just to throw some more numbers out there for you guys...

Approximate cost to build/launch a shuttle is 1.5billion dollars.

A space shuttle can carry 50,000 lbs and 8 people (including pilot)

A mining town would most likely consist of around 400-4,000 people so lets just play the small numbers and go with 400.

To get 400 people to the Mining town they will live in is going to take 57 flights (7 people per flight due to pilot always being there) and at 1.5 billion will cost 85.5 billion dollars.

Now assuming for each flight we load up the 50,000 lbs with JUST the supplies they need to survive (not including mining equipment) and nothing else (entertainment and so forth) each shuttle would need:

Food: 1,095 pounds per person x 7 = 7,665
Water: 182.5 gallons per person x 7 is 1,277.5 gallons = 10,667 pounds (just for drinking...does not include bathing or cooking)
Hygiene supplies: For the sake of time lets just say that each item is used at the rate of 1 per month so you need 12 deodorant sticks, 12 bottles of shampoo, 12 bottles of body wash, etc...for all your hygiene supplies. Doing rough math this is going to weigh 50 pounds per person x 7 = 350 pounds (I could be really far off on this but doing the math of converting different types of ounces into pounds is just too much work)
Clothing: lets say they each take 10 outfits and these outfits weigh on average 4 pounds each. so 40 pounds x 7 = 280 pounds (they are miners so they might just go through more than 10 outfits in a year)
Furniture: Table, 4 chairs, 2 beds, refrigerator, stove/oven, microwave, couch, 2 dressers, washer, and dryer as a bare minimum base for each household. Average weight per person is going to be 565 pounds on the low end for those items x 7 = 3,955 pounds

So far we are at 22,917 pounds for the flight and we have covered SOME of the bare minimums. Water will most likely destroy the rest of that weight when you factor in cooking and hygiene.

Basically my point is that you are going to have to run at least double the amount of flights in order to provide for those 400 people.

So now our tally is at 171 billion and I have not even begun to factor in the cost of purchasing the items. That cost is merely transportation!

I could keep going and going with the math on this and you will watch the bill rise and rise into an astounding number but I am not going to. Because anyone of sane mind would see how the cost benefit is largely in favor of exploring all options on earth before wasting more money in space.

Re: Space exploration - The How and Why

Well I do not think the Russians would strike with nukes, and furthermore, if they were fearful of this, they would seek to build their own life boat, and we see another "Cold War" but instead of nuclear weapons, we get "lifeboat shelters".

Also, the life boat being self-sufficient then goes back to my original points doesn't it? In order for it to be self-sufficient, it severly limits its destinations (the moon is not one, since I don't believe that there is any resources of any value there). Furthermore, solar panels are not infinite, and they do burn out in time, so solar itself needs to be replenishable, so we are back to where can a colony get everything it needs in order to be self sufficient?

In fact, I would imagine a life boat would be more placed in orbit around Earth. That way, any resources needed are easily (well relatively easier) to deliver, but I guess that still qualifies as a colony in space...I do however think that this would not be started until a disaster was imminent, since the cost vs payoff is still quite high (cost being the resources needed to start the project and the payoff being the likelihood of a disaster).

No... you're missing the timeframe.

Let's assume it takes the US program 2 years to finish their lifeboat.

For the Russians to adequately have a lifeboat to prevent the asymmetry problem I described above, they would need to build a similar lifeboat before the US finished its own lifeboat.  This puts them at a couple disadvantages, first because the Americans had a head start, and second because the only way to finish earlier would be to find some inefficiencies in the American program and correct them... a procedure which was likely to be done already by the Americans to minimize the timeframe anyway.

If the Russians can't beat the Americans in the lifeboat construction, the Americans would still have their first strike opportunity gained from the lifeboat.  Thus, the Russian would have that incentive to first strike before its completion.

But if the Russians beat the Americans, you end up with the exact opposite problem: now the Russians would have the opportunity to deliver a first strike.



> Also, the life boat being self-sufficient then goes back to my original points doesn't it? In order for it to be self-sufficient, it severly limits its destinations (the moon is not one, since I don't believe that there is any resources of any value there). Furthermore, solar panels are not infinite, and they do burn out in time, so solar itself needs to be replenishable, so we are back to where can a colony get everything it needs in order to be self sufficient?


I'm conceding the limited amount of destinations.  Remember, I'm the one who suggested to you in chat the idea of colonizing an asteroid in orbit of Earth.  tongue

As for solar panels, how long does a panel last?  If the average time a colony would need to remain self-sufficient is 2 years (the time it would take an asteroid-disaster to wear off), and a solar panel lasts 10 years... you're fine.

What stopped the US and Russians going at it before MAD? I still think the President had a bunker that would protect against a nuclear blast already...

I give your invention the worst score imaginable. An A minus MINUS!

Re: Space exploration - The How and Why

A properly doped (scientific term) graphene wall would be able to prevent bleed over of temperatures. 100 degrees inside, -100 degrees outside, and from the inside the walls would feel 100 degrees warm.

And the walls would be thinner than a cotton shirt (though actually applying ones hand over the surface would peel a small amount of skin as you went... graphene is like hills and valleys and should sheer off lose stuff and skin is actually fair loose in those terms)

Of course using graphene would require a bit more technology (right now the largest peice of pure graphene is still smaller than a sticky note) but... it can be done.





And Riddler... I am a truck driver myself, and there is one more in the game who drives, fyi.

Oh and for a 700 mile trip my company typically see's $1,800 and I get 17%. I get to see the actual charges we charge the customer.

Re: Space exploration - The How and Why

So Einstein you make 44 cents per mile then. Which is even higher than the national average.

And while yes, your company see's $1,800 what they in turn spend out drops that number still. Keep in mind they have to pay other employees (non-drivers), a whole host of taxes, and maintenance issues.

But of course, you already know that tongue

Re: Space exploration - The How and Why

darwins law needs to be rewritten to include idealogies. no longer shall the weaker creature die. the weaker beleif will now die. evolution continues!

why colonize a planet other than to harvest rare minerals, if we can survive in a giant space station, make it your home, we cant move a planet, we can move a space station.

for energy, lets hope that something comes from dark energy, dark matter, even anti-matter, aswell research into absolute zero shows that matter reacts amazingly differently proposing even more options for energy use, storage, and efficiency. this being even more possible stating that it is really cold in space already

Thermal conductivity of graphene: 4.8-5.3E3 W/m.K making it one of the best conductors of heat known at this time

Graph_A_ne does have insulative properties, making it interesting for a lot of electrical applications (high temp superconductors etc.), but it's definitely not going to be the material of choice for insulating space colonies. We'll save our graphene for the space elevator.

Never attribute to malice that which is adequately explained by stupidity.

Re: Space exploration - The How and Why

Check the various types of doped graphene, then try to post it.

I specfically said doped graphene.


I.E. a layer of graphene, a layer of the doping material, and a layer of graphene.

The various tests with graphene continue, but one version of a doped graphene has proven to be a significant insulator.

That's not what doping means...

Re: Space exploration - The How and Why

Riddler... actually it's unique.

The owner has a dispatch company, dispatching 500+ trips a day for his clients. He also owns two trucks as a seperate company.

I believe the bill is for the trucking side only... not the dispatch side where the employees are.

Repairs and maintainance is the only other costs than fuel and pay. And fuel is always a part of the contracts (part of that $1800)

Re: Space exploration - The How and Why

better yet, colony vessels that would support inhabitants indefinitely - send a few dozen of those out to the stars, ensuring that at least one would eventually establish a viable colony somewhere, and then we could be free to go ahead and have our ww3 and decimate ourselves.

Re: Space exploration - The How and Why

It's not really a layer, but insets of atoms between inside the 'valleys' of Graphene.

Go look it up yourself.
