Killer Asteroids from Asteroid Mining

Many great developments and goods will come from space industries such as asteroid mining. But with every new technology or capability comes the potential misuse and weaponization of those capabilities. It is imperative that such dangerous possibilities are addressed before errors occur.

In recent years there has been a great deal of hype about preparing for a possible collision with a stray killer space rock. People are scared that what happened to the dinosaurs may be repeated. The trouble is that while the world has been working to create ways to deflect these rocks which might hit us, others have been working to bring them right to us.

Asteroid mining is going to be a reality. Telescopes are already mapping potential candidates and companies and NASA are creating hardware to retrieve them. The reason space rocks will have to be returned to a close proximity to Earth (most plans intend to have the rocks delivered to Lunar orbit) is so they can be mined easily. Why drive a truck to a mine over and over when you can just bring the mine to the factory?

The meteorite which was supposed to have killed the dinosaurs was believed to be several miles in diameter. Now there are no plans by anyone to return a rock that big, now or in the near future, though it will undoubtedly occur someday. But a rock only 20 meters in diameter can have more strength than a nuclear bomb, as witnessed with the Chelyabinsk meteor.

All it takes to move an asteroid is a little bit of power and time. The intentions, when these
asteroids are being brought toward Earth is science and mining. However, what protections and countermeasures will be in place when the ship moving the asteroid is hacked and put on a collision course with Earth? What if the ship just loses control while carrying what is essentially a nuclear payload, if allowed to fall to Earth?

The key to stopping an asteroid impact is knowing that it is coming ahead of time. What will be the lead time when an asteroid, supposedly under control, breaks free of the leash? A pedestrian can jump only if they know the car won't hit the breaks, but we all know that a car is supposed to stop at a crosswalk so we don't look for it. We may be looking for the stray rock but it might be the one everyone knows about that gets us.

Preparations for defending Earth from space hazards must be pursued and considered. Natural events need to be prepared for, but so far humans haven't had to fear nature so much as other humans, when searching for a source of annihilation. Asteroid mining creates a plane with nuclear bombs which could be hijacked by terrorists.

Many solutions already exist to prepare for the event of a rock getting off the leash. Fortunately, large countermeasures are not something which have to be implemented for sometime. Conventional weapons are allowed in orbit, and these could destroy small asteroids coming toward Earth. Proper security protocols will inhibit most hacking, but cyber-security is a perpetual arms race. A very simple solution would be to have a certain location far away from the Earth where asteroids could be delivered and broken up into smaller pieces for Earth delivery. If a rock doesn't remain in that area it is immediately counted as a rogue and destroyed. The trouble is this solution creates a great inhibition to asteroid mining companies which need the asteroids as close to Earth as possible to allow proximity to mining technology.

Asteroid mining is going to happen. Asteroids will be brought to Lunar and even Earth orbit. Generally there will be no dangers with these practices. But the possibility will exist of having one of those rocks getting loose or being loosed and falling toward Earth. Countermeasures must be created for this event. It is far more likely than some killer asteroid appearing out of the darkness.

Martian Society

Mars One Concept for Initial Mars Base

Mars will likely be the first planet, after Earth, which humans will have a permanent presence upon. But what will a Martian society be like? How will it develop and what will Martians be like to trade with. What will be the state of technology. And what will be the mindset of a Martian. In order to create a multiplanetary economy these are all questions that must be explored.

Here are the basic predictions we'll cover in this post. Mars will be agrarian. It will be technologically advanced initially. Martians will be highly independent. Mars will be an ecological experiment station. It will lead advances in agriculture and genetics. It will be a planetary country. Any commerce, at the beginning, on Mars will be basic bartering and trading.

To imagine Mars will be agrarian is a given. In order to survive initial colonist will be required to have a firm grasp of agriculture. This will continue for perhaps hundreds of years as farming is the only means to produce the food needed on Mars. It will remain the focus until Mars  is terraformed.

In the early days the farming will occupy the attention of many of the people in a colony. The limited space and inhospitable environment will require constant attention be given to farms to ensure they produce adequately. Automation and robotics will likely come to replace the amount of attention and labor given to day to day farming activities. However, the farm will remain the primary focus of the colonists. Therefore when they gain time for research and study it will be toward methods of improving the farming techniques to increase their standard of living

While Martian society will be based on agriculture the society will still be technologically advanced. In order to land and then live on Mars for any period of time requires technologies which are not commonplace on Earth. There will be a dependency of Martian society on that technology. And, in order to grow at an appreciable rate the best and newest technologies will have to be delivered. Not to mention the fact that genetics and material science will be important aspects of Martian survival based on the farming foundation. Both of those fields require highly advanced technology. But since exploitation of Martian resources to produce such products as silicon chips will be difficult, Earth will have to supply it. Technology will be the Earth's primary export to Mars.

In fact, as compared to Earth the technological infrastructure of Mars will be greater. This will be a side effect of establishing a colony on Mars. Anything that does not have to be landed will not be landed. For this reason communications will be wireless from the very beginning and computing will likely be in the form of orbital data centers. Such a system simplifies the delivery of such technological payloads from Earth.

Concerning power generation. Mars will begin using solar and nuclear powersources. Coal and other fossil fuels will not be an option. This will again leap ahead of Earth. Perhaps to such an extent that even orbital power plants will be in use early in the society due to the access to Earth delivery craft. Nuclear will be an option since fears of such technology will not exist on Mars.

To explain why such technologies as nuclear reactors will not be feared on Mars we should discuss the people. To be blunt Martians will be the best people alive. Mars is to far away and too expensive to send herds of people to. Even if a launch from Earth becomes inexpensive the cost and risk of landing large groups of people on the planet are too great. So with fewer people being delivered they will be sifted.

Unlike the Americas Mars has few initial resources to draw from. The people that are sent to Mars will have to be geneticists, botanists, and farmers who are able to adapt Earth ecology to the Martian environment quickly and without hesitation. When we say "farmers" that is exactly what we mean. Not some professor of agriculture but a farmer who has been able to make horrible ground yield a crop. Practical experience will be essential to all Martian settlers. When creating a colony intellectual pursuits will have to be focused toward practical decisions and action.

Now, since all of the people that are chosen to become Martian colonists will be practical and scientific individuals they will not have a mindset obscured by propaganda. Fears of meltdowns and the like, which inhibit nuclear power on Earth, will be ignored by Martians who have no such luxury as fear when there are only a few options that will work for them.

This practicality and intellectual aptitude, which will grow in Martians, will make them highly independent. Perhaps even more independent than the Americas were. The continual need for survival, little chance of return, and a far greater lack of resources than in the Americas will force Martians to depend on no one but each other.

Martians will have to be very tolerant as well. To be cooped up together for long periods of time will require it. Even as colonies grow into enclosed cities all Martians will be in close proximity to each other.

The colonies will also likely be only one single colony. It makes no sense to attempt to colonize a planet with multiple small settlements. The foundational work and infrastructure is too great. Earth's international affairs will likely move far enough along that only a single colony will ever be attempted, supported by all parties involved. This raises the diversity line again. The colony will have to adopt a single language and societal structure which will span all the cultures that will arrive. This commonality will be helped along by the practicality inherent in early Martians.

From this single colony Martian society will grow. Since multiple colonies will not be pursued multiple Martian cultures will not arise early on. This will create a single Martian society. Unlike Earth, Mars will not be a planet filled with countries, it will be a planet-country. Certainly, if Mars is ever terraformed then cultures and customs may come to vary just as they do when you move from a farm to a city on Earth. But the governmental, economic, and societal structure will be unified over the entire planet.

The economic structure of Mars will be long based on trading and bartering. Trade some carrots for some cabbage, or a potatoe for some water. The need to survive again working. As a Martian city arrives and not everyone is working to survive then currency will arrive. It will be digital from the very beginning. Mars will never adopt any kind of paper money. The technological aspect of Martian society will never require hard physical money.

Now, the biggest question is how Mars will trade and interact with Earth. Earth will be holding the leash of Mars for some time. Earth will provide the capital, technology, and transportation from the get-go.

As far as how much control Earth will exercise over Mars, it will be nominal. The only organizations to send colonies to Mars initially will be governments and non-profits. Even today much of the Mars movement is coming from foundations, and even Mars One will likely not turn a large profit. There is little commercial value in Mars.

But since those Earth organizations working to establish human presences on Mars are doing it for the sake of doing it they will not have any interest in the colony once it is established. While Britain wished to control the American colonies due to the value of it natural resources and taxes from residents, Mars will have no such resources since its population won't be able to grow as quickly as America did and it has no significant resources.

Once Martian society is established it will have one principle export. Its knowledge and technologies developed for agriculture. Mars will be a hotbed of agricultural and ecological innovation. Experiments and advances will be made due to lack of regulation and danger of negative affects to the barren environment. These advances will be needed on Earth as its population continues to grow. The need for more efficient food production and possibilities of climate control are all problems that will be tackled on Mars.

The great aspect of all of these technologies is that they are not material. They will not be hard goods but information. Information and knowledge can be transported very cheaply from Mars. It requires no rocket fuel just a little electricity. Martian exports will be the genetic designs and agricultural technology which allows that society to flourish on a planet ill-suited for it.

So to sum up. Mars will be a technologically advanced agrarian society which will be fiercely independent of Earth. Its citizens will have a myriad of backgrounds but will all be extremely talented and practical. Mars will form a planetary country and will trade agricultural advances with Earth for technological supplies.

This discussion and theorizing could turn into a book very easily. We have only done a poor job of scraping the surface of what a potential Martian society would be and much of it may never come to pass. But as the reality of a Martian society comes into view these topics will be important.

Orbital Data Centers

Cloud computing is the idea of storing data on a server or having that server perform tasks so there is less load on your computer. But these servers are located in warehouses on Earth. They require large amounts of energy, they have a large footprint, and they have to transmit data over a distance to your computer.  What if server farms were placed into orbit? What if cloud computing occurred above the clouds?

Orbital server farms would have several benefits to their terrestrial counterparts. The first is power. In orbit there is an abundant supply of solar energy, twice as much as what enters our atmosphere and hits the ground. It is also possible to be in continuous sunlight. This provides a clean and inexhaustible power supply for the farm.

Next, there is an abundant amount of space in space. A server farm may grow as large or larger than any building on Earth with.

Last, concerning transmission time, space really is halfway to anywhere. Today and in the future satellite transmission will be common. The trip up and then back down takes only millionths of a second but that is very slow for a computer which works with billions of operations per second. Halving the distance of transmission by just sending information down, instead of up then down, would increase internet speeds.

But that is a far rosier picture than reality. While endless solar power is available in orbit it would still require huge arrays to power a server farm. The ISS solar array is the size of a football field and provides 110 kilowatts of energy, enough to power 55 houses. But a 55,000 square foot server farm on Earth uses 5 megawatts or enough to power 5000 homes. Clearly a development in space power systems will need to be built. But computing is becoming more efficient all the time so such power requirements may not remain standard.

Next, indeed a server farm may grow as large as it wishes in orbit. But with increased size comes increased weight and therefore higher launch costs. The cost of space launches would have to become a thousand times cheaper than the cheapest SpaceX launcher existing today in order to compete with terrestrial installment. However initial launch costs may be offset if lifetime power costs were lower due to orbital solar plants.

Last, while internet and communication speeds may be twice as fast by placing the servers in orbit this may not be a significant enough trade-off for the risks of creating such a facility. But Google and others are working on using satellites to provide internet connectivity to the world, adding a few servers to the satellites is not a great leap.

But perhaps the biggest problem of all to such facilities may be cooling. Servers become very hot and require constant removal of heat. But in space there are few options for heat removal. Heat can only leave by radiation. But a satellite using solar power is also constantly absorbing heat as thermal radiation. If a satellite also has a hot server farm at its center then a substantial thermal management problem arises.

Despite those challenges here is why such data centers will exist. Just as Google and Facebook are trying to provide internet connectivity to places where there is none, so to do they need to provide data storage and computation. Second, having large power hogging facilities in orbit will reduce the load on Earth power plants and not be in danger of blackouts while using the Sun's energy. Last, if humans go to Mars they will need computing power. But it makes no sense to attempt to land servers on Mars when they can perform just as well in orbit and perhaps provide services to multiple settlements. The same goes for the Moon. The effort of landing a sever farm on another body is to great when it can just be parked in orbit.

The latter scenarios may be where orbital computing systems begin. Providing computing resources to future Mars missions. Small server farms requiring nothing on the scale of terrestrial data centers could be created and then launched to support space missions. This is something that already has many engineering precedents in places like the ISS. It a project which is well within current technologies to achieve and could actually be built by a small firm or just a few people in a garage. From there such orbital data centers could follow a modular growth plan where new, self-contained modules are continuously combined to create ever large server farms which are able to finally provide meaningful quantities of computation to the world or other colonies.

Data centers in space are something which have potential and are currently feasible. However in order to scale them to compete with existing data centers in a substantial way requires growth and construction of other space resources. However, small scale orbital server farms can be created to support missions to other planets which will be coming in the next decades. Whether they will ever replace their cousins on the ground on Earth is unknowable until the industry develops more.

Lunar Space Elevator

A space elevator will likely never be implemented in our lifetime on Earth. Space junk, material sciences, and general liability will all prohibit it from being a feasible system using any of the methods proposed thus far.

However, the space elevator is still incredibly viable in other locations. Small moons and large asteroids which have gravity but no atmosphere or space trash are ideal for space elevators. Since a space elevator can run off of electricity and is not limited by refueling or controlling explosions, it is far more reliable as a method of shipping items to and from orbit around a body.

The body most ideal for the first true space elevator will likely be the Moon. The Moon is a clean, fresh, low gravity environment which will undoubtedly be the base of most commercial mining and transport, due to its proximity to Earth and content of materials like Helium-3 and even water ice. The Moon will also possibly act as a spaceport to asteroid mining operations and even Mars colonization.

While rockets can be launched from the Moon easily they are still using consumable fuels. The need to use materials and weight to get something from the surface to orbit or vice versa is a waste. Rockets also break down easily, and are limited to a frequency of travel based on refueling operations and repairs. A space elevator has the potential to run off a clear view of the sun, is a simple machine compared to a rocket and is able to work 24-7 going up and down. Not to mention the fact that it is a fixed point of operations. It will always be in the same place ensuring there is no danger of missing a landing pad and hitting a habitat.

The construction of a space elevator is not as simple as just landing rockets however. The basic idea is to anchor a cable to the surface of the moon. That cable is then strung, from the surface, several thousand miles to a weight. This weight keeps the cable tight. It is similar to if you held a string with a ball on the end and then spun around. An elevator car can then run along the cable to and from orbit. All of this is possible with the materials available today. And while the set-up is risky and stringing several thousand miles of cable straight up from the Moon will be expensive, once established the elevator has little potential for problems afterward. And the cost to operate such a structure would be fixed over its lifetime just as the railroads are.

The economic benefits of a space elevator, once built on the Moon are enormous. Landing of scientific payloads would be faster and more reliable, since organizations would not have to develop landers, unless exploring other areas of the Moon. The elevator would allow for the creation of a space dock. This would be an area were spaceships would stop to unload and refuel while passengers and materials are moved to and from the Moon by the elevator.

Essentially the group that owns the elevator would own the only bridge to the Moon. It would be in the same situation as the early railroads. A colony would grow around it and all commerce would move through it. An important consideration when finding a location for such a structure.

As a business it could begin by simply offering transport to the surface at a reduced cost and increased reliability to building a lander. But as time goes on it could just be a toll elevator. A fixed cost transport one direction or the other, though seasonal costs will likely be a factor.

The business danger to this system is similar to the railroads. If it doesn't run there is still the fixed costs of  maintaining the system. Though we would hazard a guess that those costs would be minimal. Since the elevator comes into contact with nothing other than the vacuum of space environmental wear will be low. If used heavily enough it will require component maintenance but when that occurs the business will still be cash flow positive.

If the elevator were built tomorrow the real business challenge would be paying off the upfront construction cost in a timely manner while the industry catches up. Lunar mining will likely be the best solution since it can be performed autonomously and continuously. LiftPort is going this direction.

LiftPort is moving to build a lunar space elevator by 2020. The organization raised $100,000 on Kickstarter in 2014 to continue development of their design. They are intending to use a kevlar ribbon as the main cable of the elevator, which is the most vital and difficult component of the system. The elevator is meant cart lunar samples into orbit.

At this point LiftPort hasn't stated what the cost of construction would be. Though with possible launch costs and material cost it will undoubtedly be in the fractions of billions of dollars. If they succeed they will set a valuable precedent about the feasibility of the technology.

The space elevator continually appears in media as a technology to replace rockets on Earth. Unfortunately, there are just to many practical problems with such devices on our planet at this time. But space elevators are a very good idea in the correct areas. They are easy to operate, once built, and do replace rocket technologies with something more reliable. And while we have said many technologies will be valuable as businesses in the private space industry, lunar space elevators will likely be the most likely to succeed. Their superiority to conventional space transport is unrivaled from a technological and business standpoint. If a space elevator is built on the Moon those who own it will control much of the industry in that area. No one will swim a river when they can cross a bridge.

Seasteading as a Foundation for Space Law

There are several examples in history which can be used to avoid stumbling blocks in the current and coming space economy. Antarctica, America, etc. However, anything that has happened in history is now set in stone and cannot be experimented with only theorized upon. But space is an expensive place to go, experimentation, with technologies, and particularly law, in cheaper settings would be highly useful. Fortunately, there is a place that serves as a viable testing ground of space communities and how they will interact with Earth communities.

Over the last few years there has been a small movement for what is called seasteading. It it all predicated on the idea of creating what amounts to artificial floating cities or countries, on the earth's oceans. This movement is now lead, primarily, by the Seasteading Institute.

At the introduction of seasteading a book was written to outline challenges to seasteading, some technical others legal. Not surprisingly, many issues discussed in the book will be faced by space communities.

The seas are a legal fuzzy area. While after a certain distance there is technically no jurisdiction countries can still exercise authority for a number of reasons. There are dangers of pirates. Questions exist of whether a floating city can truly define its own laws and standards of conduct. How would an isolated community support itself financially or justify its construction? How does an artificial structure support the biological needs of its inhabitants. All of these issues, which apply to a community in the unclaimed, empty, shifting, blue void, also apply to a community in the unclaimed, empty, shifting black void.

While seasteading is an expensive and risky undertaking it is far less so than the creation of a space station. Movers in the space industry should consider this movement very seriously. Any world decisions made about free, privately-funded entities in international waters would likely be applied to free privately-funded entities in international space.

If such floating cities were created the space industry would be able to explore and even shape the political, social, and financial ramifications of space flight in as close a simulation as is possible. If technologies must be tested and proven so to should the sociological designs. Seasteading can provide this opportunity.

The creation of islands on earth can define how the islands in the sky will interact with the world they are leaving but still interacting with.

Space to Earth Delivery

Currently most of the effort in the space industry is toward getting things into space. However, there will come a time when we will be trying to bring more stuff down from space. Materials mined from asteroids, completed manufactured goods, finished experiments, and other products that were mined, grown, or made in space will require a means to bring them back down.

Intuitive Machines' TRV (Terrestrial Return Vehicle)

NASA has already begun addressing this problem. Intuitive Machines' Terrestrial Return Vehicle is being created and is intended to begin testing on the ISS in 2016. The purpose of the vehicle will be to provide a quick means to deliver time sensitive experiments safely back to Earth where further analysis can take place which can't occur on the space station. The design is expected to be launched from the station and then maneuver to and land at the nearest spaceport.

Delivery from space is a very viable business opportunity. Especially since commercial space stations, primarily from Bigelow Aerospace, are only a maximum of 5-10 years away. While NASA is taking the approach of creating a special vehicle for the task that is not the only method or business model.

A delivery company from space could begin as simply an organizer. Buying space on returning capsules for materials from other space stations. This would actually change the business dynamic of commercial launches, who's operation generally relies on only one ticket, round-trip or one way, to one customer. As traffic increases one organization can purchase the trip up but then someone else can reserve the trip down.

The reason NASA and Intuitive Machines are creating a single miniature craft for the task of delivery from orbit is schedule flexibility. Renting space on a capsule is fettered with the schedule of the capsule launch. But cargo, particularly experiments, may have expiration dates. The TRV ensures rapid delivery whenever needed. Just like Amazon, same-day delivery is the holy grail.

So what is required for a technology that drops things from orbit on command and lands them safely? This is dependent on the cargo. The TRV is a smal craft for deliverying small experiments. The small size allows for multiple craft to be delivered to the ISS in a single launch. The TRV is also outfitted with a maneuvering system. It is basically a complete small spaceship.

TRV being launched from the ISS

The complete spaceship design for the TRV is acceptable for the current state of the art and the amount of cargo transported. But as time passes completely disposable spaceships may be too expensive. An alternate method could be something along the lines of a space gun which launches small capsules of goods which are delivered from locations in orbit. This would eliminate the need for internal propulsion of the capsules and may simplify capsule design from lifting body to the more common tear-drop shape. Though such a system would not be required for several decades. Until inter-orbit transportation and exchange is common. Basically the "space gun" would be the post office and there would be mailmen going around orbit picking up "packages" and delivering them to the "space gun."

Concept for blanket used in asteroid retrieval in space

Going even a step further and considering asteroid mining. At some point the materials within those rocks will have to be delivered to Earth if they are to have any value. The trouble is that most asteroids burn up as they enter our atmosphere. A method will have to be devised for delivering these rocks safely to the surface so their contents can be collected and sold. Something along the lines of an ablative blanket could be created which protects the asteroids from the heat of reentry. (similar to how asteroid miners plan to protect water rocks from the sun's heat) Or perhaps large skeletal landers could be created which have a heat shield and a parachute. These landers could be filled with mined material or raw asteroids and landed, then, perhaps, even reused.

While all the focus as been on getting into space the need to send stuff back is growing everyday. The ISS needs to return experiments. Planetary Resources may need to land rocks. Private space stations may need to return manufactured goods. There may even be a need to send parts down to earth to be repaired and returned at the next launch of a capsule.

In order to develop an economy in space a two-way exchange between Earth and space must be set-up. Getting up there is great, but it matters little to the world unless something comes back.

Space Movie

How often have great designers, engineers, and scientists been interviewed, and when asked about their original inspiration they reference some movie or show.

Star Wars, Star Trek,  2001: A Space Odyssey, Buck Rogers, The Jetsons. These movies and TV shows have literally inspired thousands of people to make the fiction fact.

Now, within the last ten years, point to a movie or TV show which could be the definitive media trigger to inspire new technologists. Many will respond with Interstellar, Avatar, Star Wars, and Star Trek. But the trouble is, of those answers, only Interstellar and Avatar were really new concepts. But across the board, none of these movies had at their core the wonder of discovery or space travel itself. Interstellar was not about exploration but about a man separated from his family. Avatar was not about exploration but the dangers and warnings to consider in it.

In the last decade there has been no single movie which has defined the glory and wonder of space exploration and expansion. In the movies where this has been a possibility, Space has simply been a backdrop, not the focus.

How can an industry which requires a level of public opinion and knowledge to survive, by driving tourism ambitions and potentially tax dollars, survive without becoming a part of  culture.

Movies and media really define the state of American society at any given time. Space exploration used to be lived and breathed by everyone, when the moon landings were happening. Today, the attempt to land a rocket on a barge to reduce spaceflight costs by factors of 10, barely makes it onto Google News.

A movie needs to be made about space travel and exploration. A movie which actually captures the imagination and hope of the world. A movie which makes people "starry-eyed" about space travel again.

The date of the launch of the Jupiter II of "Lost in Space"

While we at "The Space Economy" are not fictional writers, what story could be more endearing than one set ten years from now when the space industry is fully active. Every space movie in recent years, or ever, has begun 50-100 years in the future. People will be amazed and excited by a date at the beginning of a movie of just 5-10 years in the future.

Interplanetary Communications Company

As the space industry begins to look beyond Earth orbit, communications systems better than those currently used will need to be implemented.

Let's focus entirely on communication with Mars. This is the target planet for most manned missions and the Moon is able to communicate directly with Earth without special systems.

In order to communicate effectively with Mars there are a couple issues that must be overcome. One is the six minute time-lag caused by the distance to Mars. The other is the fact that signals are periodically blocked by wither the planets or the sun moving in front of the communication satellites.

The second problem is the simplest to solve. It just requires more satellites. Perhaps two around each planet so that the signal is never hidden when the satellite goes behind the body. At least two would have to be built around the sun for the same reason. Mars One is utilizing a system like this for its communication with the colony it intends to establish. But they will only be using three satellites. One around each planet and then the sun. This system will ensure that there is only a few two hours periods of blackout when a planet is in the way as well as two week periods when the sun gets in the way.

While the system is effective, for a limited mission, it is not ideal as the colony grows and activity increases. Two weeks of blackout will not be acceptable. A problem of bandwidth will also arise, with increases traffic, which will require multiple satellites in order to transfer information quickly and reliably enough.

Eventually an network of dozens of satellites around the sun and each planet will have to be created to ensure optimized 24/7/365 communication between the bodies.

Then comes the issue of time lag between planets. Relativity stops us from overcoming this problem with available technology. There is no way to have a live conversation effectively between Earth and Mars. So ways of creating the illusion of instant connectivity will have to be created.

Again using Mars One as an example. They intend to allow astronauts to download websites to a colony server to browse on a regular basis. All this requires is a periodic data-dump to the colony with a copy of your Facebook feed from 4 hours before.

The trouble with this system is that it requires a server in the colony, taking up weight and space. If a single company was maintaining the "phone network" then satellites around Mars could be outfitted with local servers just for the purpose of storing information. This would not only reduce the requirements on each new Mars mission to integrate local servers in place of food, but also allows for Mars to develop an information independence of Earth as it grows. Such a system would ensure that Mars would have a completely formed information infrastructure that anyone on the planet could access without having to build it themselves.

Now this is an audacious goal, one which would take perhaps decades to implement but it can begin now. A space communications company can be created which could initially be profitable be serving as the communications hub for NASA research missions as well as potential manned missions. If someone moved quickly enough they could be contracted by Mars One to build and launch a system in the next five years.

It might not even be necessary to build everything from scratch and launch it. If the budget is really tight, it might be possible for a company to purchase existing Mars satellites that are considered obsolete,  then refurbish them remotely to become an effective communications network, limited though ti may be.

Such a communication entity would ensure that systems are standardized for all missions since agencies and companies will not want to develop their own communications systems when they can simply piggy-back an existing one.

The business model for a space communications company would most likely be one of a basic data plan. How many gigabits does the organization want to send across the network? OK. They cost this much. This has worked well terrestrially and there is not reason to think that it wouldn't in space.

It has been mentioned how an interplanetary communications company will eventually change into a planetary communications company just by being the foundational network for a new world. But there is one other aspect as well. As individuals and companies begin to truly go out into space to explore, prospect, colonize it will still be necessary to communicate with home. But the same limitations apply, lag and bandwidth. A series of satellites set up to aide communication between Earth and Mars would also become a hub for all space communications. Whether they be from the asteroid belt, Jupiter, or Venus. The network created to communicate with Mars would become the network used to communicate with everything else. It would basically be the telephone booths and operators of space. That is a successful business. Becoming the primary information carrier.

Companies such as SpaceX obviously realize this potential.  SpaceX recently announced partnering with Google and Fidelity to create a space-based internet service for Earth. This is just a stepping stone, to pay the bills, until Musk can create the connection with Mars.

Ecological Benefits of Space Mining

At The Space Economy we continually work to explain the benefits of space commercialization. One that has been overlooked by ourselves and the industry has been the ecological benefits of using resources from space. This pertains particularly to the mining industry.

Mining has a tremendous ecological impact on our planet. Mountains are literally removed every year on order to supply the raw materials needed for our increasingly industrialized planet. But this may not be a sustainable or required practice. Space mining would be capable of replacing it and without negative ecological impact.

Asteroids are rocks out of the ground already floating in space. Excavating them has no negative impact on our solar system, as long as it is not done in orbit. Thousands of times more material is also available in our solar system, which can be exploited, with proper infrastructure, which is growing ever closer.

Many space advocates sell it as something which is the future of our race as a means of survival from cataclysmic asteroid strikes and the like or as a means to satisfy the human needs to explore. While these reasons are founded, they do not resound with some parts of the population on earth. Space has to provide some other benefit than simply making money, exploring, and preventing destruction. Space must create a more encompassing return for Earth to be worth it. Ecology is one of those returns. The fact that the commercialization of space will help to solve ecological problems on Earth is a grand reason to work toward space.

Now, certainly many will argue that space mining will still have negative affects on earthen ecosystems. Because dirty rockets must be launched and rocks dropped from the sky.

This view has little credence as it assumes that rocket technology will remain as it is, which it won't, and that the asteroids would have to be delivered as raw materials to the surface of the Earth, which they won't. Space mining will revolve around the refining and manufacturing of materials in orbit (or possibly on the Moon) which can then be delivered to earth with a gliding space plane. And rockets are already powered by combinations of hydrogen and oxygen which combine to create...water. In fact, the kerosene burning Falcon 9 is "cleaner" than the solid rocket boosters of the space shuttle so we are already creating a greener space industry.

Mining companies would do well to explore space mining as a part of their future. Not only are the resources abundant, but the good will that it would generate by "working to preserve earth ecosystems" would be valuable to the company. And along the road space technologies developed could be applied to Earth problems. Caterpillar, which makes mining machinery, apparently sees this potential as it is partnering with NASA to develop space mining technologies.

Asteroid Mining

Asteroid mining concerns the finding and then mining of any of the rocks which float around in the void.

In order to be successful, a mining company in space has to do just what a mining company on earth does. They have to prospect for potential mother loads. Then figure out how to extract the materials they want. And finally transport all of that material to some one who will buy it to build a space station or a cellphone.

Several companies are already working toward the goal of exploiting the resources which are available in space. Planetary Resources in near to launching their first asteroid tracking satellites and Deep Space Industries is developing technologies which will allow humans to refine and use the materials mined from the asteroids.

Mining has always been one of the main reasons for going to space. The vacuum above our atmosphere is not as empty as many believe. An abundance of raw materials float aimlessly in space. Approximately 37,000-89,000 tons of these rocks fall to Earth each year. The value of asteroids comes from the fact that many many of them are expected to contain quantities of rare earth metals, such as platinum, as well as basic elements like iron and sources of water.

Planetary Resources is currently focusing on the rare earth metals that asteroids could supply to earth markets.

However, many critic mining companies who are going for the rare materials which appear to be abundant in asteroids. The traditional argument is that as soon as a company creates as steady supply of the materials to the earth then the market will become saturated, prices will drop, and the ability to finance the expensive space missions will disappear.

While this argument is legitimate to a point (if gold were common it would not be valuable) it is short-sighted.

First rare earth materials like platinum will be in high demand for sometime no matter how large the supply is. Materials like platinum have untold untapped potential. The demand would grow if it were possible to work with pounds, instead of grams, of the metal and its cousins.

Secondly, companies like PR are nowhere near to creating a supply that will saturate the market. Within ten years they might be able to retrieve an asteroid the size of a basketball.

When space mining companies do grow they will quickly grow out of the need to rely on earth-based markets to pay the bills. Once the infrastructure is set up, these companies will be the ones to provide the water and raw materials to build space stations and colonies. The prime technology behind DSI is their zero-gravity 3-D printing technology which will allow them to turn rock and raw iron from an asteroid into a beam or plate or someday a rocket nozzle.

And concerning the inability to pay for expensive missions with the profits from mineral returns, that assumes that space launches and missions will remain expensive. This is clearly not the case seeing that space launch companies like SpaceX have already dramatically reduced the cost of launch and are continuing to do so.

In reality asteroid mining has far fewer market obstacles than many of the other space ventures being pursued.

Unlike the space launch industry, there is currently more than enough demand for the materials space mining companies intend to deliver. And that demand is not within the space industry but across many ranging from battery manufacturing to catalytic converters.

Mining companies also have an unlimited growth potential, however far into the future you look. No matter how technology changes the raw materials will always need to be collected to build the stuff.

Space mining is a great industry to be on the ground floor of right now because the demand is there and the possibilities are many. The only problem a fresh entrepreneur may have getting into the race is the cost of creating the technology to deliver the goods. Even though PR and DSI are using off the shelf components and micro vehicles they are still not cheap companies.

But, if someone in a garage would like to contribute to space mining there are some technologies which could be pursued quite easily.

Currently there is no definitive way to securely land a craft on small space body. The lack of gravity makes it almost impossible to just set down on the surface. Stemming from this problem is the problem of grabbing a rock and putting it in tow. And then once the asteroid is secured tools and techniques for actually mining it in space are still on the drawing board. Any of these problems are hardware and even software problems which can be pursued and solved on a shoelace budget and a little clever design.

Asteroid mining is happening. True, it is only in its early stages but there always has to be the first prospector to go to California and find the first nugget. Asteroid mining will be one of the foundations of the future space economy. The infrastructure it creates, information it gathers, and the materials it refines will support nearly every other aspect of space travel, colonization, and commercialization.

Here is a great presentation on the quantitative aspects of asteroid mining

Space Arena

Space Stations are one of the most expensive propositions in the private space industry. The only one in operation today is the ISS and it is estimated to have cost $150 billion in construction and occupation expenses. Certainly, the construction of the ISS is a poor example, especially when comparing to some technologies in the private sector. SpaceX is reducing cost of launching stations and Bigelow Aerospace is making stations simpler to build and deploy. But even so, constructing a "building" in orbit is not a cheap or easy proposition no matter how you look at it today.

The cost of a space stations is not all that surprising. After all it is something which has to provide all of the comforts of home (i.e. food, air, water) with none of the resources. It has to keep humans alive in one of the most inhospitable places for life that we know.

But does a space station really need to provide all of these resources in order to have value? What is a space station really for in the private space industry, as far as money-generating options?

A space station can be a place to rent space to companies to perform experiments in zero-g. It can become a space hotel to paying tourists. It can be a stop-over to someplace else.


These are all very viable industries once people gain a greater presence in space. But again, all of these "products" for a station to act as are incredibly expensive. Because they are meant to separate a person from the outside.

But if someone is going to go to space for the experience, they probably will not want to be separated from the outside by a cramped station or capsule. They will want to get the full benefit of the absence of gravity and the views of the planet and stars.

So why not build a station that doesn't protect anyone from the elements but instead just keeps them from getting lost. Build a station that is basically a giant cage.

Such a structure would basically be a Space Arena. A huge playing field where spacefarers can get the EVA experience without the safety hazards.

From a design standpoint it could be a huge geodetic structure which deploys to create a faceted sphere which is covered in a soft mesh that keeps things and people from floating away. Easy to build, deploy, and maintain. All of which decrease the cost of the station.

Instead of having to launch it in sections it could be launched in a single unit, perhaps on a Falcon Heavy, and then literally just sit there. Since it wouldn't require any complex life support systems those would not have to be maintained and since space has no other stresses than changes in temperature there is nothing to wear out the station structurally. And other resources such as the development of orbital tugboats become available, it wouldn't even be necessary to have much of an attitude control system.

With this kind of station all the travelers need is a spacesuit to keep them protected for the elements and a capsule to go sleep in. Both of which are already necessary for the trip. So why have a station which is a repeat of both of the other two just on another scale.

Since the permeable station is easier to construct and maintain is is easier to to make large. The size of such permeable stations allows them to be used by industries that have yet to consider space. The station could be used as a playing field for a space sport, creating a viable return and interest to people on Earth. It also gives a complete "space experience" to any tourists, much more effectively that a standard station. Just imagine the difference between seeing the curvature of the earth through a porthole and being able to have a panoramic view as you fly, un-tethered in the ether.

The experience and the low cost that such a "Space Arena" provides makes it a viable entry into the industry by many companies other than the standard aerospace and research firms. It is something that could be pursued by the entertainment or sports industry.

The business model for the company which owns the station could take any number of forms. If the station was built for space tourism it could be like a low cost motel. Travelers pay to use the space during the trip. If it is created to host space sporting events then it may pay for itself through the interest and entertainment value of the sport.

If you consider the Space Arena something akin to a stadium in orbit for sporting events it is actually much cheaper than earth-bound stadiums which run anywhere from $500 million into the billions. Whereas the cost to build and launch the Space arena would likely be only $150-200 million dollars. Still a huge gamble but it also has more utility and range of markets than a basketball stadium does.

The creation of a "Space Area" is something which really has very few technical hurdles. It is really a matter of "just doing it." The only things for a company or entrepreneur to consider with such a station is that it can increase the risk of a standard space excursion. Imagine someone in a space suit pushing off of one side of the sphere and then colliding hard with a structural member on the other side and perhaps over-straining their spacesuit causing it to rupture. Safety will be a huge concern for such a venture but materials and designs do exist which can help to mitigate most of these risks.

As far as space stations go the concept of a "Space Arena" or permeable space station are concepts which are relatively unexplored and potentially underestimated. They are a structure which can be easily and cheaply constructed and can be used to create a fantastic space experience both for those utilizing the station and to those on Earth, if it is used for televised sporting events.

Orbital Zoning

For nearly sixty years humans have been sending objects into orbit. Some are weather satellites, others digital TV, and some are just junk. Though there is a huge volume of orbital space above Earth to put satellites in, orbits are in fact filling up and and are largely uncontrolled. As the private space industry grows the need to zone and regulate orbits for particular uses and organizations will be increasingly necessary to create a safe and effective orbital airspace.

To clarify this concept let's look at a scenario. Imagine a company, such as Bigelow Aerospace, has constructed an orbital hotel. The station sits in an orbit several hundred miles above Earth. Now another company developing a space BattleBots show decided to set up shop in the same orbit. This is allowed because no one owns the orbit or can prohibit anyone else form using it. Unfortunately, the Spacebots end up smashing each other to pieces in the orbit, much to the enjoyment of Earth spectators. But now there is an increase of debris which could easily puncture the soft hull of the space station. While the Spacebots would be held accountable for the damage the entire problem could have been avoided if the space station was able to zone its orbit for only human occupation. This is a slightly silly circumstance but the point is clear.

The same type of situation is the reason that factories can't be built in residential areas here on Earth. Similar rules must be set up for space. It will not be possible for space to continually be treated as an international free area like Antarctica. People and organizations actually want to go to space and get something from it, in this case a location.

Orbits are real estate, just as on Earth. There are certain locations better suited for certain tasks and some that are filled with dangerous litter. But there are a lot of orbits above the earth. The 3-D nature of the Void allows for this, as well as the fact that everything in orbit is moving and can be coordinated.

So how does one go about defining property in a place where there are no boundaries but simply the "idea" of locations?

Well the simple place to begin would be with altitude. Space could be divided into more altitude layers. Within those altitudes one could then define particular orbits just as radio bands are defined on earth. Particular altitudes could be reserved for earth observation, others for communications satellites, and then the areas above the debris-filled orbits could be reserved for space stations.

Then within the altitudes particular orbital trajectories could be defined. A company would be able to purchase these trajectories and maintain its hardware within them . But this opens the question, from whom does one purchase an orbit, something which transcends any type of Earth boundary.

The likely solution would be to allow for homesteading of defined orbits. Organizations and Countries could agree to allow ownership of particular orbits through a system of placing improvements in them. Then once ownership of an orbit has been established, through the International Homesteading System, the orbits can be sold. This does require international cooperation but that is the case in many aspects of Space Law and a topic for another time.

Enforcement of homesteading boundaries will be an issue. How to keep vehicles in their space and ensure no one trespasses will initially fall to ground-based tracking and monitoring of payloads as they are launched. But eventually a Space Authority will have to be established to act as a "traffic cop" for Earth orbits. It would go around checking the authorizations of certain satellites to be in certain areas and perhaps "towing" them when they are not.

The issue of spy satellites will also be a problem. These craft are some of the best kept secrets in the world. Governments will not want to register spy satellites or even relegate them to particular altitudes. But as slowly as orbital space is filling this issue may resolve itself before it has to be addressed for private needs.

Space will eventually have to have a system of organization or regulation. Responsibility for space debris and sharing of orbits will become too large of issues to simply ignore. Orbits will become crowded and at that point everyone will want to know what is theirs, else the industry could become quite confrontational. This can't happen because it would be self-defeating to the development of a Space Economy.

Note: A particular example of where zoning of orbits would have been useful would have been in the Chinese Satellite Missile Test incident. Again, it is an issue of international relations but if the Space-Faring nations had collaborated to allocate weapons testing orbits, other nations and organizations could have avoided those areas and now not have to dodge debris.

Space Food

A company for the manufacture and distribution of space foodstuffs.

Within the next ten years a permanent commercial human population will be established in orbit and beyond. But how will these people be supported. An entire industry based upon the needs of these space residents and tourists will need to be created.

Food will be the most difficult consumable to supply to these space communities. People can live with stale air and recycled water but food has to be an experience filled with flavor  as well as nutrition. But creating something that meets those two criteria while, ideally, having a shelf life of months, without refrigeration, is a tall order. In the old days salted pork with an occasional orange was considered a complete meal, our more civilized society must create something better for our explorers.

Food in space has been a challenge that even NASA has not  met yet. While they have learned to freeze, vacuum seal, irradiate, and store food so that much of it will not spoil on a long trip, and even still have some flavor, there are some foods which we take for granted on earth that are considered  delicacies in orbit because they simply can’t be prepared or obtained in space. Baking bread is a supreme challenge which isn't completely solved.

All the deficiencies in the cuisine of the Void are opportunities. Food is something that is easily redesigned and adapted while also having infinite possibilities and potential. And the best part is the products are needed today and not only in space but right here at home.

Many facets of the space food industry exist. The potential for space gardens and specific tools for accomplishing the kind of culinary feats that are possible on Earth are all applicable, but for the purposes of this post we will focus on the opportunity for providing prepackaged food that is meant to be a meal “practically” ready to eat in orbit.

Here in the early days of the space industry which is heavily focused on tourism and government contracts the food will have to be of a special kind of hybrid. It will have to provide a pleasurable experience that is unique to space but also contain the nutrition to allow someone to live off of it. This will require that a space food manufacturer create an initial product that is almost nostalgic, the kind of freeze dried and in a toothpaste tube that tourists would expect on a trip so that they can feel like their image of astronauts. But this paste would still be something that someone who isn't  just in space to visit can live off of.

In order to cut on costs it would likely be something along the lines of a paste or solid bar that can be shaped and formed into whatever the customer needs. So just like ice cream, where you can use vanilla as a base for chocolate or strawberry, this Space Paste would contain all the nutrition a person needs but could be flavored and shaped into whatever the customer wants. Soylent is a current product that very nearly meets this criteria.

Such a product would also need to deal with yet another problem brought on by space food, boredom. How many people can say that they love to eat oatmeal morning noon and night. Food is something that adds excitement and interest to our lives. A space food that can be practical, in that is can be packed stored and provide nutrition, but also fills the human need for change and diversity in flavor, is exactly what is needed today. 

Fortunately, unlike so much of the space industry, the technology and products developed for space food will not trickle down to be used in the earth food industry as so many space developments are claimed to do. It would, instead, be immediately and directly marketable without having to redesign any part of it. Imagine extremely dense nutritional supplements that are able to be packed and stored for years while remaining light weight. Such products could be loaded into disaster relief trucks or into hiking backpacks. Any company that produces such wears would not have to depend solely upon the space industry to sustain itself.

The competition in space food will be fierce. While food designed for space is applicable on Earth, the reverse is also true to some extent. After all it would not take a great deal of effort for brand name protein bars and supplements to be customized for space.  And the infinite variation of food doesn't allow for much protection through intellectual property. But a small start-up can certainly gain ground by moving now and gaining contracts with the rising private launch companies , with paying customers who want their space peanuts during the flight.

A company dedicated to space food would be something that would certainly be able to diversify. While an initial product would want to be a catch-all design, all further developments could  range from old style toothpaste tubes of peanut butter to the creation of the most advanced recipes and cooking equipment anyone has ever seen. Really, the creation of food in space is one of the most difficult pieces of chemistry that anyone has ever had to undertake.

The market for space food has existed for some time. Space museums and other tourist traps have long provided freeze dried cuisine just like the astronaut used to make. In the actual industry the government space agencies have been the only providers of TV dinners fit for the space station. This won’t continue to be sufficient. Human traffic is only going to increase and NASA is continuing to lose their budget and is not prepared for food production in large quantities. Just as new launch vehicle providers need someone to make spacesuits they need someone to cook meals. It can and needs to be done today, and even if it means freeze drying your favorite smoothie blend, it would better than what the industry has available now.
