These where small scale impacts and yes they would have released water if they hit the right spot but the water is just as likely to refreeze at the poles or settle onto the permafrost layer again.
These are not powerful enough impacts to remove atmosphere in sufficient amounts and there is also likely to be atmosphere gained by volcanic action which from the size of those shield type volcanoes we do know exist. I wonder if we have the more powerful supervolcanoes present too?
Still they are impacts and they cause localised issues. They could throw a lot of dust into the atmosphere and make a dust storm strengthen.
National interest is something as well
In what form? Is this by possession, owner ship, occupency, military might...
Occupancy gives you a say in what happens and in this case especially of a treaty which just does not work. There will be a form of occupancy possession which allows the user to utilise the area and materials there. National interests mirror commercial interests here.
We already have the Russians and Chinese and even the Indians intrested in the resource potential of space and pushing that could increase public and therefore political support.
So true that they are getting to the point where they may be able to execute a plan to get them there in a manned mission before the US.
Im unsure if we can take the verbal announcements of some seriously and others lack the infrastructure/finances and experience to actually manage there statements. Still time could and likely will change this so best to get in first.
The purpose of the ISS was based in science, study of manufacturing as it relates to material science and medicine, the human body studies...
And we have yet to send the actual main science labs up, as the ISS reaches its end of life. So making any stated purpose evident as illusion.
How about expanding the base to include recyling space vehicles either whole or in parts to form new ships, construction materials to expand the station by melting them down, to make orbital green houses, manufacturing of rocket fuels from waste.... oh I forgot none of these are science so we can not do these.... These things all relate to colonization, expanson of the human presence...
All this holds true for the moon or mars for once the science has started so must the aspects of learning how to live there.
Will the construction of a moon base mark a great leap in planning for a human mission to Mars or prove a wasteful diversion of funds?
That’s when inflation and current budget projections just make it difficult to continue at the pace that we are on right now,
Right now it may be early to tell how the opportunity for partnership will play out but so long as the US costs are 10 times those of a partner nation for a like kind item Nasa will continue to have difficulty in getting funding for the projects of the future.
Strictly speaking one advantage of the Moon is that various national systems will not have to fundamentally go in front of a committee just to see if it might effect another nations mission element. The ISS as a combined collection of various elements and from just about every space fairing nation was such a complicated hodgepodge that the various methods and in some cases the actual design philosphy created problems and tensions.
It is a case on the Moon where we will only be connected by electrical systems and possibly air and water subsystems. It makes sense then for the nations to develop a single set of warning and access systems like airlocks and to standardise the atmosphere used for safety reasons as well as reducing complexity. This is not fundamentally expensive and in the case of the Moon allows the various nations to design base elements they believe would give the most benefit. If science experiments in the European science habitat could interfere in another nations hab then it is easy to move the European science habitat further away so that the problem is resolved. This is something that could not happen in the ISS where the closeness of modules meant adding a bit could well interfere in another nations hab.
Developing private enterprise driven habs could also reduce costs especially if there is a standard set of items to be used. And power systems will tend to rely on solar access and if more power is needed add more solar cells. Burying the habs puts them in a constant tempature where stress reduces so increasing service length as well as reducing maintenance.
Not enough impacts and certainly not of enough power.
If it was pure snowball type asteroids then that would be a different matter.
There is justification for staying at the Moon and it is not just for scientific reasons.
It is reasons that the public and politicians alike can understand and in that understanding we have not only there acceptance but there support.
I agree but the but has to do with developing commercial capability to get to the moon. When none exists. It is the same issue for COT's for the ISS.
There is more than just plain commercial reasons that can be used. National interest is something as well, even though there is not anything coming from the Moon immediately there is the potential for it to happen and similar to what occurs in Antartica, missions are kept there just in case legal and other frameworks change. The Outer Space Treaty which restricts commercial and national interests is unlike the Antartic treaty a very shaky treaty without real broad public support and one which could well fall if any of the intrested and active parties withdraws.
We already have the Russians and Chinese and even the Indians intrested in the resource potential of space and pushing that could increase public and therefore political support.

While the ISS is expensive it does not need to remain that way if commercial use was encouraged to reuse what gets dumped back towards the oceans. What goes up should stay up..
The moons expense is one of equipment delivery to become self sufficient thou this in and of it's self will come at cost to mars future missions.
Will it ? I have serious doubts as to the usability of the ISS and even its actual purpose. It appears to be a station in need of a purpose and one which due to domestic political concerns and ignoring the engineers does not help the furthering of the push to space.
Commercial delivery to the ISS is a good way to reduce costs and to promote an increased US space capacity but will the ISS have a future?
Developing a purposeful and deliberate plan for the use of a space station is something that should have been done before it was launched and even the construction method (piecemeal) has lead to the stage where the ISS is getting old and worn out before it is even finished.

This is probably the hardest of things to fix...
It does depend on what we plan to do and how we do it. It also depends on the red tape that seems to flow out of everything goverment being cut. And nothing more seems to increase costs than the cost + system.
Cyclers are for routine deliveries of large numbers of personel and equipment and may be the only way for future colonisation.
Still we could always use NIMF technology to provide the shuttle service
Much of the expense of a Moon/Mars crew rotation and supplies are tied up with propulsion to get them there. The Moon and Mars both have resources to dramatically reduce the propulsion requirements for a given mission.
...coming from the guy with ISRU issues.
ISRU utilisation is not a problem. As long as the belief that it solves everything is not taken for granted. Mars direct is an example where everything is skimped to make a program work to the point it really becomes for Mars exploration worthless.
There's a danger in saying we need to go to the Moon to stay permanently because there's no justification for doing it. It can be justified in terms of preparing for the Mars mission, for lunar science and perhaps farside radio astronomy experiments. Those are limited activities, sure lunar science can go on and on but the cost will be way beyond its value. A Lunar base will make the ISS look cheap. It's important to focus on Mars otherwise the Moon will consume all NASA exploration funding. Mars is the future.
There is justification for staying at the Moon and it is not just for scientific reasons. It is reasons that the public and politicians alike can understand and in that understanding we have not only there acceptance but there support. The ISS is an incredibly expensive white elephant and can only be improved by expensive deliveries from Earth. This is not the case with the Moon and unless we find the means to decrease costs while increasing our capacity for action in space then we will not get to go to Mars anywhere in the near term like the 21st century.
This is more focused if we consider colonisation of Mars which is not an economic or scientific necessity rather that of a dream of many. It can only happen if we can reduce costs and allow for the creation of larger vessels to transport ourselves across the solar system. Only the Moon can realistically allow us to do this. We are very lucky to have so many resources close to us and in a place where we can actually utilise them.
A Lunar base can be made to work it is not the structural knightmare that is the ISS and it has a real purpose rather than the make work waste that is the ISS. We have to ensure that costs do not overun.
cooperation will be a problem but so will the viewpoints of the other space agency partners. There has been a lot of designs by these agencies how they would go the Moon and a lot of research into how this should be done. Using Japan as an example there Moon plans are heavily into robotics and this is something that can be reasonably fitted into the NASA plans. But other agencies like Russia are more into putting money back into the corporation and this they will do likely by selling private seats to the Moon and actively looking for commercial interests on the Moon.
GCN is just trying to ensure that when we get to a point we stay.
Apollo for all its success was just about getting to the Moon ahead of the USSR and this it accomplished. Once this had been achieved the political and public support dried up and the Apollo programme did as well.
If we want to go to Mars and stay we have to ensure that the will is there before we go. Otherwise it will be oh you made Mars ok come home now mission accomplished. Some politicians will slap each others backs and state how they can now make savings to pay for some other "important" iniative.
There is much to do on Mars, far more than the Moon. Initial surveys will take many years and people will have to stay there for at least 18 months at a time. So a permanent base makes sense as soon as possibe. With the access to water and the vast range of minerals, ISRU is viable and the possibilities are almost limitless. Given the vast distance to cross getting there and the enormous expense, it's vital that the architecture used is affordable, scalable and sustainable.
Certainly there is a lot of things to do on Mars, but not everyone believes in the future of space and it is these people who will oppose permanent missions to Mars. Unless it is stated at the beginning and agreed that we go to the Moon and Mars to stay we will end up like apollo finding ourselves stuck in LEO or worse without a manned prescence in space at all.
The planet Mars is a glutton for punishment.
Scientists have found no less than 20 new craters etched into the red planet’s surface from space rocks that pummeled Mars within the last seven years [image].
“If you were to live on Mars for about 20 years, you would live close enough to one of these events to hear it,” said researchers Michael Malin, who led the study. “So there’d be a big boom and you’d know there was an impact crater.”
This indicates that when we get to Mars that we have to seriously consider thickening the atmosphere quickly. And until then we will have to have a very effective Skywatch
I think we should at least give the idea of O'Neill type space colonies a thorough study. How close are we those capacities, and how much closer are we than the 1970s when they were proposed. the Ability to build an Island One or a Stanford Torus is the first step in the construction of manned Starships, we should try to develop a space construction capacity for that reason. Presurvation of the Human Race is another reason. Humanity remains vulnerable if it is stuck on one or two planets. Mars colonies ought to be easier to get started as they can start small, but we shouldn't stop there. Inhabiting space ought to reduce our concern with the global environment, since we won't be living on a globe. This greap leap into space has been tougher than anticipated, but I still think we should make the attempt.
How much closer are we to the capacity to build O'Neill type space colonies. Easy to answer that we are not much further than the 1970s. We have gone forward in some cases but the true technology needed to make it happen is cheap relaible space flight and that is not present and is nowhere in sight.
We have gone forward in some ways like the improvement in Robotics and the ability to automate solar cell production but not much further than that.
Oh, and tugs using electric fields to push off the Earth's? Uh, the Earth doesn't have an electric field. Try a MagSail instead.
The Earth does have a magnetic field it is this that is used to repel a tug from LEO to higher altitudes and it can then attract itself back down to LEO.
Electrodynamic Tethers: Getting into the Swing
It is not a fast system but it does benefit from simplicity.
-On the equator of the Moon, you only get about one week out of the month of peak solar power when the Sun is overhead. Maybe stretch it to 10-11 days with gimbaled panels, but thats extra trouble. Since a railgun will be power hungry, this is the worst-case time you would have to operate the thing.
The solution is simple using our plans to create automated solar cell production we then build solar cell farms to the west and east and connect by buried cables then keep going to increase power supply to the point we actually are working. At the lunar poles it makes sense with the horizon being so close and that we then we will have almost constant power supply. The lifeblood of our space exploration. And when we move to another point we simply connect into what will be a quazi lunar power grid. When we leave the poles to go to the equator we do the same there and connect to the poles.
There are asteroids on the Moon already. Every crater you see has the asteroid that made it underneath its surface.
Yes but most have been destroyed in the collision. PGMs come from the class of asteroids that are metal rich and in this case due to there strength they may well have survived depending on the collision dynamics more or less intact.
Tungsten really isn't worth much much, it makes an awful radiation shield because cosmic rays would generate a nasty shower of particles. In fact, the Tungsten would probably multiply the radiation from cosmic rays.
I agree tungsten from the Moon would not be a realistic effort for any civilian programme. But there is a military use that if it is cheap enough could make it happen. The use of so called rods from god is a weapon system where tungsten inert impactors are dropped from orbit to destroy deeply embedded and strengthened bunkers. Cost has always been a limiter and if it is decided to go with this system then cost becomes the single most important issue. And supply of such rods from the Moon would likely be cheaper from an already present medium size PGM working base.
PGM deliveries to Earth will be more effectively financed if it was part of a regular shuttle service between the Earth and the Moon. But it would benefit from an electric space tug which could take cargoes from LEO capable RLV's to the more expensive in energy GEO area for cargo transfer and then to return the incoming cargo for later collection by RLV.
Electric field generating space tugs can use the simple effect of being opposite to the Earths magnetic field to propel themselves from LEO to GEO and can use the opposite effect to attract themselves in.
Completely on another thought you do know there is almost as many people in Canada calling themselves Scots as there actually reside in Scotland.
Very happy I am now
What you describe is called the crud and the incident happened about three years ago if I remember (RAF personel from the falklands had to go in to help run the base).
In the antartic even the janitors have degree's and with so little time time available to do experiments and work the people at the station ignore the little things like looking after themselves and so they get sick and it spreads to others.
They have now imposed hygene rules like having hand cleaning stations just before you enter the base galley and a rule of common courtesy if you get sick you stay away from others.
The last space walk they tried to free up the antenna but was not able to get it to move. Orbital repairmen will have to try again, Heavier-duty tools may be used to free jammed antenna on space station
The article goes into details as to what happened and how to the antenna.In most recent news the stations attempt to boost its altitude was cut short when a break reset making the change only about a kilometer rather than the expected change to allow for the next shuttle mission in under a week away now on the 7th.
Another attempt will be made on Monday.This reboost problem has happened before with it cutting out and was ok on a second try but I wonder if it is time to replace that circuitry...
So heavier tools.
Is it just me or does this not bring to mind they are calling for a sledgehammer.
So in space emergency repair procedure 1 still applies
There is a lot more to do with the Moon than just use it as an upgraded Hubble. We will learn a lot about our sciences on the Moon from material sciences to the geological origin of the Earth.
The upgraded Hubble will be the JWST. The moon is not a good place for optical or IR astronomy, it's dusty, its temperature changes a lot, it has gravity and rotates. Probably all new telescopes will be constructed in free space.
Actually the Moon is the defacto perfect place for radio telescopes, the blocking of the Earths signals. The Moon may be dusty and has tempature swings but this is only on the surface place anything about 1 metre under the regolith and the tempature remains almost a constant -20 centigrade. Another point to the Moon being used as a place for telescopes is it is stable and also almost in constant vacuum.
This stableness is why the Moon will be the place for all the best telescopes. Using the law of Interferometry where a telescope at the lunar North pole looks at a target while at the same time another telescope on the south pole does it as well then what we have in effect is a single telescope with the resolving power of the diameter of the distance between the telescopes. This would allow us to observe not only planets going around extra terrestial solar systems but major geologic features of these planets.
Now do not let this title fool you..
Russia Will Develop Space Elevators
Russia seems to say a lot nowadays :?
Seriously, I voted 'no' because it would maybe be good to be beaten to Luna
Ah but this is a poll on should the US lose the race to Mars. It certainly cannot be beaten to the Moon can it
There are laws that prohibit that today, signed by most countries around the world and I don't think any country would risk a war over that.
Yes the 1967 Outer Space treaty. What a really vague treaty, does it allow private ownership of extraterrestial real estate or not? In my view it does not allow ownership but it does allow the use of and ensures non interference. It is that term non interference where the real problem with the treaty comes down to.
I land a robot on Phobos but so later does NASA I claim my mission is being interfered with and so NASA by nature of the treaty must either leave or take the case to the international court of justice.
There are points in the solar system where an advantage is gained by ownership or in the spirit of the treaty stewardship. Mars has the two Moons which allow for potential space stations as well as fuel stops. Olympus Mons is simply the best place for the placing of any Martian space elevator.
The Outer space treaty needs to be firmed or replaced but there is a lot of resistance to this.
What should the US do with its manned Lunar space program base once we start going, in hopefully 2018 or before
There is a lot more to do with the Moon than just use it as an upgraded Hubble. We will learn a lot about our sciences on the Moon from material sciences to the geological origin of the Earth.
The main purpose of the Outpost is to prepare for missions to Mars. Calling it an Outpost is deliberate, it shouldn't be a full scale base initially - that would be too expensive and not required
Though there is much that can be learned from basing on the Moon for a future Mars mission I wonder if it really comes down to confidence. With a Moon base we have the ability to get back to Earth if something goes wrong in a matter of days and so when nothing does go wrong it increases the pressure to go for Mars.
And of course if we can utilise the materials of the Moon then we gain a major advantage in our ability to function in space.
What makes you think our politicians will be looking inward once the Solar System has been settled. By that time we'll have become our own "Aliens from Outer Space," and the nations of Earth and their tiny antagonizms long forgotten!
But we have seen in our colonisation efforts on Earth that this is exactly what Does not happen.
Mars will be close in communication unlike these old colonies and so contact with family and friends will be still there. People will build the way that they believe is best. (it is why domes will be more popular than underground bases: Larger open areas are prefered by Humans) They will also take there culture with them and these new colonies will absorb that culture and learn from it and it will be the basis of the nw Martian culture. That is why the USA tends to be called the anglosphere like Australia and Canada. But Quebec is french orientated and South America Spanish and Portugese orientated. Language has a lot to do with this but it is also what is behind the language the points of view that it is based on.
So it comes down to control and colonisation rates. Certainly if western orientated states are the prime colonisers and control the certain most important strategic points on Mars then they will dominate the emerging martian cultures.
Getting a bit silly but.
China has a decent space industry at present but it costs very little in comparison to western counterparts since China pays its engineers very little. China's growing economy will put a major demand on these engineers for a lot of projects. And it will increase there wages and cost in developments especially as domestic corporations will want them as well.
It will take China to decide to build heavy lift to go for the Moon and Mars and until we see this China has a good LEO craft and could orbit the Moon but landing is something different without tricky multiple launches.
So yes the USA can beat China to Mars but it is the tortoise and Hare race here. It will come down to who can actually send enough colonists to actually dominate the planet and no one is near that stage yet.
Except that presumably these are seven responsible adults, who all want to go on a mission.
Is it really so difficult for seven people to agree together what they are going to do?
The problem is not that of 7 people agreeing a decision it is when it comes to 100 or 1000 or 10 thousand.
Anarchy does not necessarily mean violence.
Anarchy means that no one is in charge.
A good example of this is the world postal service. There is no office, or group of people, who control international postal services. Instead, agreements are made between individual national postal systems - and the mail gets through, without anyone being in charge.
But the International postal service is the creation of goverments and there agreements. Most if not all postal services where created by the goverment to provide a badly needed service and often one of national strategic necessity.
This has been expanded by various treaties but the core of it is the national postal services which are lead by directors,postmaster Generals call them what you will.
So Anarchy is something that cannot be atrributed to the postal service it is actually a state controlled engine of mass communication.
There will be a point when a computer has intelligence.
But will it be a computer with silicon chips probabily not we are reaching the point of there not being effective. It could well be that computers become biological/Technological hybrids.
They could also be crystal based matrices.
In the end it comes down to invention and humans wish to create such a device.
Certainly there is a demand for greater and greater computing power but is it true intelligence?
Who Knows the turin test even that is not really a definite test just that of perception.
