Space Islands from Space Waste

Eventually there will come a time when humans are able to fully access and exploit the infinite raw materials in space. But there will be material which is disposed of as asteroids are mined for precious and useful metals. The rock and dirt will simply be thrown away. But this may be one of the most valuable material.

Space is a different environment from any that we have ever experienced on earth. On earth certain things can be ignored or discarded and they will simply be reabsorbed by the world until a use is found for them. Living in space doesn't afford the luxury of waste. As new industries and products are created that use the resources of space they must take a comprehensive view of how to use those resources.

Space mining will be one of the first to experience the need for total resource utilization as it will be the one of the first product-based industries in space. (satellites are a service-based industry)

Not all of what is mined from asteroids will need to be dropped to earth to be used. As it stands now the only thing worth dropping are the precious metals. But some of the other useless minerals will likely be turned into spacecraft, and large asteroids may be hollowed out to be turned into ships or space stations. But these processes are energy and engineering intensive. Another way could be created that would be used to create space real estate. All the left over materials could just be thrown into a pile with a little glue.

Masses of land could be built, with very little effort, from the debris left from space mining. From that, settlers and organizations could set up habitats on the bodies. These large bodies could have the benefit of special configurations and orientations. they could be built as large disks which can always face the sun, allowing access to a large energy source. They could become space docks. They could even be used as resorts.

Over hundreds of years these large masses of rejected dust and dirt could start to form the basis of a small Dyson Ring or Sphere. Far fetched and distant but very possible.

This post post is meant to draw attention to a use for the useless. Space mining will have waste. When an asteroid is stripped and ground up, many of the minerals will not be worth saving or transporting, unless a use already exists.

This is simply a heads up that one man's waste is another man's resort island.

Builders Wanted!

Space is a perfect industry for a rebirth of old ideals. Today software is king. Computer scientists, programmers, and entrepreneurs work to find the next silicon based solution to any problem. In space, information technology is important but not the end-all-be-all. Space is going to require people with practical knowledge who are willing to get their hands dirty. Mechanical engineers, mechanics, technicians, farmers, laborers, etc are going to be the careers in demand as space travel, and particularly, colonization begin to take off.

The reason software careers are so prevalent today on earth is because much of the infrastructure has already been created. The fiber has been laid, the computer production has been automated, the software engineers' houses have been built. Space does not have this physical infrastructure that allows information systems to operate. There is no way to created a more efficient habitat using an app on Mars if there is not an existing habitat.

Students who are in high school today, or even professional engineers currently, need to wrap their
head around the opportunity coming their way. People who build things are going to be needed. From the launch to the landing. Schools can also encourage this slightly by realizing that being a farmer or builder will have a future.

All this stuff that has to be created also is going to be entirely new. It will require new techniques of manufacturing, new design methodologies, new materials. When outfitting a lunar home you can't simply go to Ikea and grab a few coffee tables, though this may happen if a crunch arises.

Now, software will still be needed. Space will be highly robotics based. Unmanned system may prepare sites and build structures. This will require a huge amount of information technology and the programmers that go with it. But robots have their limits. And when it comes to creating things they are highly limited. (Yes the Singularity will likely change that but lets not go down that rabbit hole at the moment.) And there is still the issue of building the bodies of the robots that must perform these tasks.

Space is a frontier. In order to conquer a frontier "ideas" and "apps" are not enough, something must be built. And since this frontier is entirely new entirely new things must be built. Students and professionals might consider preparing just a little for the onslaught that will arrive in about a decade when space travel will be gaining speed. A smartphone cannot plow a field and a robot, currently, can't design furniture for a space station. In order to be a big part of space you will have to build something tangible.

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.

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 Robots as Heroes

The space programs of the past and the space industry of the future is subject to public opinion and support. This was true of the moon shots and it is true of each of Apple’s unveilings. If people don’t care then success is substantially more difficult.

Space Robot Justin

Robots are a great way to explore space. They are cheaper, safer, and faster than humans.  And, as artificial intelligence increases they are becoming as capable as a person. So why risk a life if the job can be done by a machine?

Public relations. A machine does not elicit a response from people that makes them stand and root for it. Curiosity landed and continues to provide amazing images and great information but no one outside of the space community cares. Voyager is now in interstellar space, no one cares. Opportunity  has survived on the red planet for 11 years , no one cares. Sending people to Mars? Great press, though potentially a fraud.

Now certainly humans do need to be in space. Space is there for us, not the machines. But machines are able to blaze trails and provide information in far more effective ways than an astronaut with a wind gauge can. But as entrepreneurs in the space robot business get started how do they work to gain the public support for a Mars rover that is remotely similar to an astronaut?

Star Wars R-Series Robots

For this to occur engineers must become showmen. Think of R2-D2, this space robot is loved by millions even over its anthropomorphic partner because R2 is lovable and has a personality. He is just a can that beeps but everyone connects with him. Space robots must become “hims” instead of “its.”

So when conducting a scientific or exploratory mission how does one make a “him?” Let’s look at another automated space machine that has broken the mold and won the hearts of even average folk, the Hubble Space Telescope. Hubble has gained value as much more than a scientific instrument. This is because it acts as an eye to the universe. It has given the world images of the universe in amazing color. It has a name that people can remember. And it has a story which people relate to. It started broken, was fixed, was almost scrapped, but is still going. Hubble is the little engine that could, and it has survived partially through public support.

Robots and probes must become celebrities in order to have a level of public praise similar to an astronaut. The robot needs to have life on display. It needs to have a story that people can tell. The hurtles that that little circuit board overcame. The more that the machine can be personified the better.

Companies in the space robot industry which are just starting out and need to get through a crowdfunding campaign or have investors hear about them before they walk in the door, need to make their robot a person. Give it a twitter account, and Instagram Maybe spend some weight on a couple of eyeballs. Have the people building take a personable selfie with it.

A Space robots shouldn’t be scientific instruments but a friend or adventurer. The humans around the robot can give the robot the life and personality that it needs, but that has to be something that is considered when building it and sending it on its way.

Necessity for Modularity

The cost to enter the space economy is high. It it is time, capital, and labor intensive. And yet large corporations and billionaires will not be able to develop the space industry to a point where it is a part of our culture.

With only a few large players in the game there's a limit to how many goals can be scored until everyone is crippled. Even innovative companies like SpaceX will reach a critical mass where they perform only particular duties in the industry. The industry will stagnate unless smaller players can become a part of it.

So what is a strategy that smaller companies and individuals could take in order to make a mark in the space economy.

Let's use a theoretical example, Space-Based Solar Power. This concept for powering the world has been around for decades. The concept of using an unobstructed view of the largest fusion reactor in existence (the sun) is very enticing. If space solar power could be implemented then it would solve many of the world's energy problems.

Here is the problem. Space based solar power requires huge initial investment. Basically the lifetime cost of a nuclear power plant is what it would take to build a comparable orbital solar array. This is not a feasible business plan. No matter how great the design or promising the impact 16-20 billion dollars up front is not something people rush to.

So how does one take something hugely expensive and reduce the cost. Break it up into little pieces. Small companies and individuals need to lay out strategies where what they invest in today will still be useful 10 years from now. In this way the cost of something huge can be spread over years and incrementally built. For orbital solar a specific direction might be to develop something similar to the orbital power plant where te company creates smaller modules to be attached to ships and stations to serve as a temporary power source. When a significant number of cells have been placed in orbit, years from the first, then the modules could be combined with transmitter to beam the power to earth instead.

Modularity has to be the foundation of any small company wishing to build big things. The giant one hit wonder is not feasible. They must find a way to break it down. A mars colony into single identical modules. A telescope mirror into hundreds of smaller mirrors.

Modularity, building small identical things that can become larger individual things is very scalable and adaptable. If a small company is making habitats for Mars and has simply created a small-tent-like module that connects to others, then the product is as available to a single fanatic as it is to a giant corporation. And the producing company is able to make money from selling one as easily as selling a hundred.

Breaking larger structures down into multiple pieces also decreases the complexity of the design and increases its adaptability. Imagine the difference between having to redo the plumbing of an entire space station or just of the new modules.

Every new private space company is adopting this idea of breaking down the grand dream into individual components that can pay for themselves on a small scale while remaining relevant on the large scale. Bigelow Aerospace is creating, not space stations, but space station modules. Planetary resources is not creating a single advanced asteroid hunting satellite but a swarm of small satellites.

Modularity reduces cost and ensures that a viable product is created more quickly. If anyone is considering creating a space company and they are not a billionaire, they must design the product to be modular and relevant for years. This ensures scalability, adaptability, redundancy, and early returns.

The dreams of launching an entire space station or colony in few shots can't be done by the entrepreneur in a garage. But sneaking into orbit bit by bit is very feasible. And as launches become ever more common the left over space will be more available and inexpensive. Space start-up have to do more with less until it can all be combined into a single system.

Space Burial

One of the more interesting space businesses, which is really as old as spaceflight itself, is the idea of space burials.

As a means of disposing of the deceased space burials are actually quite practical and even more emotional. Leaving someone in a place where they will perpetually drift and travel and perhaps even seed life into arid worlds, is a very romantic way to send them on to the next life.

Space burials have been going on since the very first moon landers. Ashes of people have been sent up ever since. Celestis, Inc is a company that has formed around the idea of space burial. Celestis purchases empty space on launches and fills them with samples of cremated remains. The people that have been buried in space include Gene Roddenberry, the creator of Star Trek, as well as several hundred other people.

However, at this point a typical space burial includes less than an ounce of ashes in a sample tube which take the ride, but then typically come back down as the orbit decays or the mission ends. Very few people have had remains placed permanently into space. And certainly, there have been no full bodies sent, only cremated remains.

Space burials as a business, are actually very simple. A basic set of vials are made and ashes inserted. Then they are placed in an empty corner of the next possible launch. Low weight, low effort, but a very moving way to be buried.

In future space burials will no doubt become much more commonplace. While they are currently reserved for rich and famous, as launches become ever more frequent so will the space to place the small caskets. Someday entire bodies may be buried in space. Though there will no doubt be restrictions on this practice to ensure that tourists in orbit are not surprised by a cadaver outside of the station.

Space burials will also grow to be much more than a typical burial. They may come to epitomize the ideals of space travel. Imagine an astronaut or scientist dedicating their entire life to space but dying before their dream was realized. Perhaps they wanted to reach an asteroid or set foot on Mars. Placing to sending their remains to those places fulfills and legitimizes their life's work and can inspire others to follow.

Space burials are likely one of the oldest commercial space businesses and will likely remain after many others die.  While at this moment they may seem a bit sterile compared to a casket and flowers, they are far more meaningful and beautiful. Space is an eternity, why not place a person's remains in eternity after they have entered it.

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.

Crashes and Accidents

A piece of SpaceShipTwo

"Space is Hard - but worth it" Sir Richard Branson

At the writing of this post the private space industry has suffered two major accidents. A failed launch of an Orbital Sciences Antares Rocket and the crash of SpaceShipTwo during a test flight, which killed one pilot.

These accidents will no doubt have huge detrimental effects to the industry which was just beginning to gain a bright outlook on the future. Public opinion will likely swing back into fear of space as opposed to the wonder of it.

It is important to remember that at this point space is at the same place aviation was after Lindbergh's flight. The technology is proven to get us to the moon. Private companies can make it into space. Now we are all waiting for the space age Boeing 247 to take us to the stars.

But creating a space liner is leaps and bounds more difficult than building an airliner, and that was difficult. There have been and will continue to be accidents as space develops. But we must not let those change the resolve to go to space.

Space is far more than a commercial opportunity. At the moment there is actually very little money in it compared to other industries, due to the expense. Space is a future that only a few really believe in and others fear. The trouble is that those who fear it want to project that fear onto others. And that fear is unfounded because it is like being afraid of the first Russian spacecraft. The fear is of what it is today and not of what it will become tomorrow. They point to the accidents and warn of the dangers which come with space travel though they have never experienced it and don't see that the "now" is not the "future."

The people that died in the accidents were not afraid because they could see what the future held and it excited them. And the only way to truly honor their memory is to continue on towards the goal that they themselves gave their lives believing in.

Any space travel company will have to come face to face with the possibility of the loss of life. But the only thing they can do is work to avoid it as much as possible. Negligence cannot be allowed, for it is the only thing which causes these accidents.

Space travel is more than a half a century old but commercial systems are coming into service. It took aviation 30 years to go from first flight to airliner. Considering the challenges and the cost of space travel we are doing decently well. But fear and accidents cannot be allowed to stop the progress, otherwise it may be delayed decades.

Space companies must be able to take the lessons learned from their mistakes and work to improve. While it may be tragic, fear cannot be allowed to win.

Fortunately fear of progress never wins. As is proven by aviation and any number of other advances. Fear is only able to slow something down but never stop it. Possibilities outweigh fear any day. These accidents may cripple the industry but they will not stop it

But possibilities only become real when they are made real. Space companies and entrepreneurs must learn how to create possibility out of tragedy. By doing this they will be able to progress without so much as a break in step. People may die but they would not want it to be in vain by having their work undermined by the failure of the company or industry that they represented in life. They are the leaders of the space crusade and others must take up their positions.

Space is the future of the human race. What better industry to support and be a part of.

Space Water Refinery

In space, water is liquid gold. It is the heart of all life and of many space technologies by serving as a source of rocket fuel. But how does one get water in space? Water is actually quite plentiful in our solar system. It exists as ice on Mars and the Moon, inside of some asteroids, and is actually a primary component in comets. But, for any of this ice to be made usable by spaceships and colonies, it has to be extracted, melted, and even broken apart at an atomic level. While extraction is being developed by mining companies, the actual refinement of water into either drinkable liquid or rocket fuel has yet to be commercially developed, but such a "Water Refinery" would be an incredibly integral part of a developing space economy.

Water is the very basis of life. Humans can only survive a matter of days without it. This makes it one of the primary consumables on any manned space mission. The trouble is, at this point the only source of water for spacefarers is the Earth. Any water any astronaut drinks has to be shipped to them on an incredibly expensive rocket. Certainly, once the water is in space it can be recycled many times and reused by travelers, but the fact that water had to be blasted into space in the first place is a practice that can't continue. As more people begin to operate in space the need for drinkable water will increase and it will not longer be viable to get it all from Earth.

That is just for drinking water. There is also a market for the creation of rocket fuel. Currently, numerous satellites fall to earth because they run out of gas. And, as planetary travel grows there will be the need to fuel a fleet of rocket ships. As before, fuel can be created on Earth and then launched into space to fuel all these craft. And with dropping launch costs that will an option. But, the components of water, hydrogen and oxygen, are actually the most efficient rocket fuel that exists.

The technology to split water into these elements has existed for many years and similar processes been researched for applications in Mars colonies by NASA. So, instead of shipping fuel from Earth it would actually be possible to just grab a passing comet and turn its water into rocket fuel at a fraction of the cost of launching it.

Of course, there are many operations that have to be in place before a refinery can begin work. The bodies with water have to be mapped. They have to be collected, that is, brought to the refinery. Then, once under control, the asteroid/comet actually has to have the ice mined from its rock and metal.

Fortunately, these are all operations that are being developed and perfected by existing space mining companies. Planetary Resources and Deep Space Industries are space start-ups that have begun to develop the technologies needed to mine asteroids and comets and even process the materials. They both expect to have operating hardware in space within the next decade. This will give the creators of a space refinery plenty of time to develop their own final product. And they will be able to focus on taking water ice and turning it into liquid water and rocket fuel.

The main resource required by such a facility will be power. It must have copious amounts of electricity available to melt the mined ice, run it through filters for drinking, and perform electrolysis on it to create rocket fuel. This means that the main part of such an operation will be its power plant.

Early on it will most likely run on large solar arrays either connected to the facility itself or provided by a space utility company. It may be possible, and certainly preferable, to use nuclear energy if such technology is allowed into space as the industry develops.

Deep Space Industries Mining/Refining Concept

While such a refinery will need storage for its product, that may be a flexible option depending upon other developments in the industry. It may be possible for the refinery to partner with space gas stations or tankers which will be able to handle the storage and delivery issues associated with such a venture. Though if the pockets of the company are deep enough it could become the equivalent of an oil company here on earth which handles every part of the production process. From extraction of the raw material to putting it in a customers tank.

So the overall operation of such a refinery would be something along these lines. Someone goes out and collects the raw water ice from asteroids and brings it to the refinery. The refinery, which operates in planetary orbit, either purchases the ice or enters some kind of shared profit system with the mining company. The refinery is equipped with the power and storage facilities it needs to process the ice into drinkable water and fuel. This is then sold to companies that wish to keep satellites in orbit longer or to power ships onto new worlds. The model is identical to an oil company and will require great cooperation between space companies since the creation of all levels of production simultaneously by a single entity would be far to expensive.

Though getting such a company started may not be as difficult as it seems. If one were looking to start small and grow to become "The Space Refinery" it would be prudent to begin by creating and manufacturing small life-support systems that can be used by single craft or small bases to make drinkable water and purify existing supplies. This would create demand for the company in the current space industry.

Then, as permanent bases and long range re-usable craft begin to be developed, the refinery company could develop the fuel creation system. The two variations of the technology could be used in places like early moon bases like a backyard still. Such a strategy would make the company a major contributor to the industry early on and give it the position it needs to implement a larger-scale independent refinery in space when the demand arises.

Drinkable water and rocket fuel are the two primary consumables for anyone that operates in space. Any spacecraft must have fuel and any human must have water. The water needed to meet both of these needs is present in the void of space and can be exploited. The only thing that is required is an individual(s) that will work to become the "Water Baron" of space by creating the water refineries needed to exploit this abundant and necessary resource.

Space Gas Station

 In order to create spacecraft, that can move around in Earth orbit and even to other planets, they have to have their tanks filled. Currently, any spacecraft in orbit goes until it runs out of fuel, then it plummets to the earth. Any manned spacecraft, like the ISS, must be refueled on a regular basis and is limited to Earth orbit since that is where the gauge hits empty for all current space vehicles. The creation of a "Space Gas Station" would create the ability to increase the operational longevity of current spacecraft as well as create a means for current capsules to top themselves off and move on into new missions.

If one is to look at some mission beyond Earth orbit, (Apollo or a Mars mission) normally, the procedure is to carry all the fuel required for the entire mission on a single launch vehicle. This is the equivalent to loading your car with all the fuel needed for a cross country trip. Such strategies greatly increase the cost of launch, especially when present prices are in the neighborhood of $10,000/lb. Certainly launches will become more economical in coming years as prices decrease, but there is still no reason to fill a vehicle with fuel when it could be filled with equipment or other supplies. True, the tanks will still exist, but the "Gas Station" would allow for smaller tanks on vehicles since journeys to fuel sources would be a bit shorter. Again, imagine a car going across country, but now with some gas stations along the way. Now you don't have to carry extra fuel or have such a large tank.

The primary issue with such a service, considering current launch technologies, is that the cost to lift the fuel for the "Gas Station" into orbit is identical to the cost of putting it up with the craft in the first place. For one-mission vehicles this is true. But what about satellites that need to maintain orbits, the ISS, an orbital taxi, or for the space shuttle to be boosted to a higher orbit, if it were still in service. In all of these cases the "Gas Station" makes a lot of sense. If a vehicle needs more fuel to continue a mission or to begin anew, then a location to refill is worth the price. Especially, when the other option is to organize a whole launch to refuel or build and launch an entirely new craft to replace the empty one.

For an example of a situation, where this would be usable today, imagine if a SpaceX Dragon capsule wanted to continue to Mars. Normally the capsule burns all of its fuel to reach orbit so that is its operational limit. If a "Gas Station" existed, the capsule could dock with it in orbit, fill up, and then fire its engines to break free of Earth gravity. This is, in fact, a maneuver that missions Like Mars One may need to consider but are only possible with a fuel station in place.

So the need for an orbital "Gas Station" certainly exists, even today. So what would it look like? If the Space Shuttle were still in operation one would assume that it could simply be one of the Shuttles' orange external tanks that was left in orbit and has since been refilled. But that is no longer an option. In the near future the creation of such a fuel depot would most likely require a series of launches with a Falcon Heavy hoisting filled tanks into orbit. These tanks could then either be combined into a single structure or spread throughout orbit to allow easier access to the fuel reserves.

In order to refuel craft, organizations would schedule dockings with the fuel stations through the operating company. Then they would fuel-up and pay based on the amount that they take. It would be identical to a normal Earth gas station.

In the beginning it would be necessary for the craft/organization in need of fuel to navigate to the fuel depot. But as the company operating the station grows it would be possible to implement mobile stations which go to where the fuel is needed or even to implement a team of drones to bring craft to it.

The technical challenges of such a project are significant. Rocket fuel is very hard to contain in large quantities for extended periods of time. Containing large quantities in orbit will be even more difficult. Then there is the problem of actually having the adapters needed to refuel the numerous variations of spacecraft. This will require the eventual creation on some type of standard across the industry.

Such an endeavor will require significant investment in early development and then the first launches. However, once the station is operational, the returns will come quickly, since the price of the fuel will be a markup of the the delivery cost to orbit. Such a station would likely only need to be emptied a few times to offset the cost of development and construction. One would have to determine the value, of the fuel, to organizations that want to give second chances to old craft, instead of launching new ones.

The expansion capabilities of such a fuel company would be unlimited. As the industry grows and space traffic increases multiple stations will need to operate in orbit and eventually around other planets. And as mining grows and water ice is brought back to Earth or the Moon the fuel stations can be filled with the refined hydrogen and oxygen. Thus reducing the price of the fuel.

These stations will become the waterholes of space. People will need and want to be near them. Because of this they could be the structures that space hotels and space docks are built off of in order to reduce the number of stops for human vehicles. Rental of such proximity space or connections will become lucrative for the company that owns the gas station.

Though the creation and implementation of an orbital fuel depot will be significant, it is a piece of infrastructure that will be so vital to the space industry that it will quickly pay itself off. It will be as important as the launch vehicles that carry the craft off of the Earth. While some billionaires are building space hotels and other the launch vehicles, it would not be a bad business decision to create a Space Gas Station.

Spacesuit Maker

If anyone wants to do anything in any part of space they have to have a spacesuit. But with each new environment a different spacesuit if required. There are suits for when a rocket launches, for when someone takes a spacewalk, for the Moon, for Mars. As the industry grows the variety of suits will have to also. Specialty suits will need to be created for orbital construction workers and extra-comfortable suits for tourists. And all of these people will always need the suits and new environments will need new suits. The market will always exist and will always be growing. Just like the clothing market on Earth now. A few companies have already started work on the spacesuits that will define the new industry. But there is plenty of room for talented individuals with a will to help people operate in space.

Spacesuits have been the domain of NASA for many years. And though there have been significant developments, spacesuits are extremely poor in design. The number one reason is because they are so arduous to use. They are like having an inflated bag around you that you must push and pull against for even the smallest movement. Even fit astronauts get a workout during a spacewalk. This is not something that would be ideal for a space tourist. But there are solutions to this problem and others that exist. Many have been researched and are in the public domain. And there are always new solutions to old problems.

Spacesuits are also not very sexy. The suits used by astronauts on the ISS today make you think of a marshmallow man with a helmet. But the current space industry is all about hype and image. It must convey a message of advanced technology and appear as one would imagine from seeing Sci-Fi movies. If the industry doesn't do this then it looks like "the same old thing." What better way to inspire people and get them behind you than to show them groups of people in futuristic spacesuits? For this reason spacesuit manufacturers have to make their suits Awesome. (SpaceX actually stipulated to thier spacesuit contractor that the suits look "badass")

But on the practical side, spacesuits are really just small spaceships. This could be a design approach in the future when suits need to be created in bulk quantities to "get the job done." Instead of working to create a suit with flexible arms and legs, a company could just make a can with arms. This is actually what the early space pioneers imagined. Such a "suit" could be used by construction crews for building space stations. Or even as a disposable unit.

What about when we go back to the Moon or even Mars. While some of the suits of the time may be modified for the terrestrial environments there will be a need for different kinds of suits in each case. Suits will have to deal with the stress of dirt and grime which is absent in the void as well as the differences in atmosphere, gravity, and activities.

Overall, spacesuits are something with a lot of design leeway allowed, a lot of design improvements needed, and a lot of niche variations required. That makes it into a very clear market opportunity. Not to mention the fact that few launch companies want to have the responsibility of creating their own spacesuits. Such side projects take away from companys', like SpaceX, primary mission of developing launch vehicles.

Orbital Outfitters Suit

Final Frontier Suit

Orbital Outfitters  and Final Frontier Design are a couple of the companies that are already working to create spacesuits for the new private space industry. Wisely, they are not only focusing on creating spacesuits that are functionally better than any suit that has been created before, but also on giving them the futuristic look that space tourists and the world will want to see. Orbital has been contracted by SpaceX and XCOR to develop pressure suits for their vehicle crews and Final Frontier recently completed a successful Kickstarter campaign.


The space industry needs spacesuits, everywhere and for everything. Construction, play, escape, appearance, planetary exploration. These many applications require many different kinds of suits.

A spacesuit company is not a particularly expensive or technically challenging company to begin. Final Frontier began with a fashion designer and an ex-spacesuit designer. Such a company can gain a foothold by making pressure suits now but would have unlimited expansion possibilities as its competence grows. And even though Orbital Outfitters and Final Frontier Design already have a head start, their solutions are not perfect. A clever designer and/or entrepreneur can improve on the spacesuit as it is viewed right now and become the source for creating a very necessary piece of equipment that the entire industry has and always will need.
