Note to Our Readers

Hey All,

Recently we have seen a dramatic spike in readers and followers to the blog and Facebook page. This is great and we welcome you.

For about the last year we have not had the time to post to "The Space Economy" very much. This is mainly because both of the authors have been consumed by exterior projects in start-ups we have been a part of. But there is a light coming over the horizon that may allow us to return to the work on the blog. The new readers are also a great incentive.

We started this blog to give voice to entrepreneurial opportunities and hurdles in the rapidly growing private space industry. Apparently we have been succeeding.

In the coming months we hope to post more frequently and use the Facebook Page as a news outlet for NewSpace stories.

Thank you to all of our readers and we look forward to creating more.


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!

Photo from "The Martian"
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.

Nuclear Devices in Space

Here is an essay that was written by one of the authors for a college course several months ago. We thought you might enjoy it though it might be better to just skim it. This paper was meant for an uninitiated audience.

Mars has long been a target of space colonization. This little planet is actually quite similar to Earth in many different ways. But in order for Mars to be a planet that is truly amenable to humans, that is, a place where people can go and walk in the Martian sun as one would on Earth, the planet has to be terraformed. Terraformation is the global engineering of a planet’s environment (Moss). In Mars’ case terraformation refers to the heating of the planet. Several methods for terraforming
Elon Musk with Stephen Colbert
Mars have been put forward. These ideas have included pumping greenhouse gases into the atmosphere or dropping asteroids on the planet. But the concept which is now receiving the most attention is one referenced by Elon Musk on the Late Show with Stephen Colbert. When Colbert asked what it would take to make Mars livable, Musk replied that “There are two ways, the fast way and the slow way.”(Colbert) The slow way was to use greenhouse gases to hasten global warming on Mars. The fast way was to drop thermonuclear weapons on the poles. It was the fast way which has received the attention.

In order for Mars to be the planet which humans leave Earth for, it will have to be terraformed. The use of nuclear weapons is one of the most practical methods of accomplishing the task. While technological challenges exist even with this approach, it will be the geopolitical and interplanetary ethics which will pose the greatest challenge to any type of Mars transformation.

Why is it that Musk believes that thermonuclear weapons would be ideal for terraforming Mars? The goal behind the plan is to create a runaway greenhouse effect on Mars. Mars is full of carbon dioxide. The tenuous atmosphere that exists there already is primarily carbon dioxide, and the poles are composed of frozen carbon dioxide, or dry ice. Detonation of nuclear weapons over the poles is expected to heat them enough to release huge amounts more CO2 into the atmosphere. Ideally, this initial release of CO2 would heat the planet enough that more CO2 would be melted, and from that warming more still, continuously until all the dry ice has been melted and ejected into the atmosphere. From there plants can be introduced to convert the CO2 into oxygen. Nuclear weapons are ideal to start this process because they are understood, powerful and compact. Other options for starting the process of CO2 release require huge infrastructures and technologies which have not yet been developed.

However, even though the plan is feasible technologically it is almost insurmountable politically. The current Outer Space Treaty which is signed by most nuclear powers of the world, and all space powers, states that no weapons of mass destruction will be placed in space (United Nations). Basically, the global UN treaty prohibits nuclear weapons in space. There is a possibility that the treaty can be amended to allow thermonuclear devices to be deployed for the peaceful purposes of terraforming Mars. After all, peaceful applications of thermonuclear devices in space have never been a large consideration. Also, conveniently the treaty does not apply to individuals or companies, and may become even less of a factor.

A bill up for vote in the U.S. senate is set to give companies control of extracted materials from asteroids, (Fecht) even though the UN treaty states that no country may control any resources in space. The U.S. bill will set a precedent for private organizations to make decisions about space utilization outside of international treaties. The bill will also allow for the United States to develop local legislation to allow private organizations to decide the fate of Mars. So essentially, the U.S. may not be internationally allowed to unilaterally claim parts of space or Mars, but it can provide the resources to a private company, not bound by the treaty to terraform Mars. This all operates under the assumption that the Space Act of 2015 is ratified by Congress. But it does present the possibility that Elon Musk could obtain the means to terraform Mars with nuclear devices as a peaceful utilization of the devices without forcing the U.S. to break its treaty.

If the humanitarian effort to terraform Mars with nukes was ratified by the UN, or enabled by U.S. legislation, there would be multiple primary objections to the possibility, both are based on safety. In order to get to space one must take a rocket. Rockets, the world over, only have a success rate of, at best, 96 percent (Lafleur). What would occur if a rocket carrying a nuclear device exploded upon launch (Jauregui)? Also what should occur if terrorists or hackers hijack the device and point it back towards Earth. These are the concerns of a nuclear device being launched.

The latter argument is inconceivable. Such a device would have higher than normal military security. It would not be as if it is a basic laptop to be hacked. If the nuclear arsenal of the US has not been breached then neither will a rocket to Mars be compromised.

So, regarding the issue of a failure. This is a legitimate concern. But what few people realize is that there have already been multiple nuclear payloads sent into space. The Curiosity rover uses a radioactive device to power itself which would have disintegrated should it have exploded at launch. There have also been multiple SNAP-10A fission reactors launched since the 60’s (Bennett). Thus far there have been no accidents. But the reality is that even if one of these nuclear devices were to explode in the rocket the danger of radioactive fallout would be minimal. A nuclear blast creates dangerous fallout because it is able to eject decaying plutonium in all directions very energetically and evenly. A rocket exploding is a firecracker in comparison. The reactor and its contents would fall out of the sky and into the ocean, not spread like a plume across a continent. Overall, the dangers of safety are arguments similar to saying that we might get hit by a car if we cross the street, so one should never cross a street. It would not be negligent to attempt to launch a nuclear cargo to Mars.

So, assuming that nuclear devices have been approved to go to Mars and detonate, the next argument for the opposition would be that of the ecological impacts such an act would have on Mars itself (Jauregui). These objections stem from the idea that humans do not fully understand Mars yet. Mars has been considered one of the prime locations in the solar system to find life or remnants of life. Mars is theorized to have once been very earthlike, warm and wet. These theories lend credence to the idea that there are either fossilized or living organisms to find on Mars (Johnson). But should humans go and start nuking the planet, they could obliterate evidence of that past Martian life, or possibly even that life itself if it still exists. This issue can be likened to endangerment and human caused extinction of animals on Earth. The trouble is on Earth there are other resources, other solutions to deforestation, on Mars those options are limited because terraformation is required to even open the door to those other possibilities. Mars must be terraformed in order to provide a human presence that is capable of fully understanding and studying the planet. This cannot be achieved with rovers, but it can with humans.

There exists the possibility that small colonies will be established before the planet is terraformed. The stations would conduct the science to prepare the planet for the terraformation and design the process. While performing these studies scientists would be able to conduct the final surveys for life. If found, the organisms can be protected from the terraformation process so that they can be fully studied. In this way the transformation of the planet will not eliminate any potential existing residents, and the scientific value of those organisms can be viably and organically retained.

Mars is generally touted as a second planet for humans, to ensure that if a life ending event occurs
on one planet the other will preserve the human race. Should initial preparation and study of the planet not be performed the terraformation should continue. It is not appropriate to put the protection of a hypothetical organism or fossil ahead of the actual dangers posed to the fully conscious and creating organisms that are human. Some would say that the dangers to Earth are of the same probability of getting hit by a car while crossing a street, which I presented previously, therefore why should Mars be colonized out of fear. To this let us be clear, if human protection was the only reason then there would be no interest in Mars. Humans can’t fight the urge of a donut even though it could kill them. The idea of a multi-planetary society extends far beyond survival as a benefit. These include solving problems such as population density, political oppression, and economic growth. A new planet allows humans to develop in ways that we have never seen since Europeans started coming over to the Americas. Mars is bare ground for people to create a new start. The colonization must occur for human progress to continue. That is indeed more valuable than a scientific curiosity which may or may not exist, and would still be able to be studied even after the terraformation. The development of the human race is also a hypothetical which is justified through the data of history and how expansion has improved quality of life but also scientific and economic ability to protect and understand environmental issues.

Elon Musk is a marketing genius. He often drops hints and ideas in order to improve visibility of projects he is working on. But he is also a proven achiever of lofty goals. He already operates several technology companies, one of which provides orbital rockets to service the International Space Station. When Elon Musk states that nuclear weapons are a viable method for preparing Mars for human colonization, it is generally a well substantiated belief and even future plan he is working on (Masunaga). Terraforming a planet with nuclear devices is a possibility (, and though there are hypothetically-based concerns about it, none of them are legitimate enough to prohibit the plan. The primary issue with actually implementing it will be the fears of what may occur on Earth, either due to potential political backlash or a failure of the vehicle carrying the devices failing. It is possible that the political hurdles can be overcome and the other is a concern based on hyperbole. Nuclear devices can and should be used to prepare another planet for human development.

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.
