Asteroid Mining Companies & Technology

There are quite a few companies across the world actively engaged in developing asteroid mining technology in a wide variety of ways. Not all are known, and most tend to specialize in a certain aspect of technology that will fit into the whole picture. In this information section we seek to maintain an ongoing record of the various commercial technologies and methods that are being developed to achieve asteroid mining. We'll also cover the more theoretical aspects of this field and honestly confront our current technological and physical limitations. Check back periodically to learn about breaking developments in the technological development of asteroid mining. As time goes on we will constantly expand this section to serve as a reference. The name of each organization is a link to its main web site if available, where you can get more in-depth information on the products or services they provide.
We are at the beginning of the steep part of the curve of asteroid mining technological development. What that means is current research is centered around prospecting, detection, transportation and navigational development. Initially national efforts will predominate, but commercial companies will increasingly follow. In the next decade you'll start to see people experimenting with the concept of robotic zero g mineral extraction. Eventually things will start to be pulled together and the technological winners of each stage will form a whole picture, and in this 20-30 year period, nations will arrange for shared telecommunications and navigation networks between earth and the main belt.

 "Asteroid Initiatives, the Asteroid Prospecting Company, is dedicated to leveraging the technology developed for cubesats, chipsats, and solar sails to dramatically lower the cost of asteroid exploration, making prospecting for resource exploitation and mining commercially feasible." If you want to get into space mining and you want action right away, the leading edge is prospecting, and asteroid initiatives seeks to be the world leader. Their approach: "Solar Scout™ CubeSat Explorer deploying Chipsat Sensors at a Near Earth Asteroid (NEA) a few million kilometers from the Earth. These sensors (about the size of a credit card) will embed themselves in the asteroid (or go into orbit around it) and measure the asteroid's properties, such as the water and metal content of the body. This can be done for a fraction of the cost of similar measurements from a conventional spacecraft."

"We are a young aerospace start-up company on a mission to exploit the potential of an off-Earth commercial market. We are currently developing a satellite to prospect the near-Earth asteroids (NEAs) for mining candidates. AMC will commercialise this data set in order to fund further development of the Asteroid Mining industry, using the revenues from the Space Resource Database to refocus our R&D on the extraction, processing and utilisation of the available extra-terrestrial materials." The succinctly named Asteroid Mining Corporation based in the UK is a new entrant in the race to asteroid mining, and they have a firm and reasonable path to get started. AMC realizes that the first step is proper prospecting and analysis of elemental composition of these asteroids to know which are the best targets to go for the earliest. To get there, they have a series of three missions planned: Asteroid Prospecting Satellite One (APS-1) 2020, Asteroid Exploration Probe One (AEP-1) 2023, and Asteroid Mining Probe One (AMP-1) 2028. Interestingly, the AMC is a champion of a version of the United States SPACE Act for the United Kingdom!

An early hopeful player in the field, Planetary Resources eventually ran out of resources in 2018. The company was especially focused on targeting near earth asteroids and had a series of planned experimental satellite missions: Arkyd-3R, Arkyd-6 and Arkyd-301. Arkyd-3R was ejected out of the NanoRacks CubeSat Deployer on the International Space Station and was meant to 'validate spacecraft technology.' The Arkyd-6 satellite mission was launched via rocket in January 2018 with "...mid-wave infrared sensor, second-generation avionics, power systems, communications, and attitude determination and control systems." Finally, the Arkyd-301 mission was a planned scan of near earth asteroids for water content using their latest construct. Anticipating the need for economy and scale, Planetary Resources dabbled with 3d printing and an asteroid survey satellite constellation called Ceres.

Myth # 1: The Main Asteroid Belt is too far away to conduct mining operations.

Right now a little roving robot named Opportunity has been rolling on the surface of Mars since 2004 and only in 2018 did a hardware error occur! This feat of technological excellence is proof that you can operate robotic assets over long range, even on the surface of a planet, for extended periods of time. All this was accomplished using already out of date technology and no infrastructure. Furthermore it is no doubt a more problematic signal to maintain on the surface of a planet as opposed to the relative vacuum of space. 
Still, maintaining a speedy and consistent signal will lead to the economies necessary to make asteroid mining a reality. To overcome the signal delay between Earth and the Main Belt, very simply a signal amplifying array between them can be established and designed in a cheap form. With regularly spaced amplifiers, a near instant signaling can be achieved with currently available technology.

Myth #2: There is just too much mass to move from the Main Asteroid Belt for asteroid mining to be economical.

Making asteroid mining a reality will be a balancing act of the minimization of mass to be transported, and maximization of the conservation of energy use. To get there, a wide array of approaches are envisioned and will be used in parallel.
Firstly, a great amount of mass will be left behind and not brought back to Earth at all, because refinement and extraction will carried out at the Main Belt as much as possible by robotic means. It remains to be seen which minerals and in what form they’re to be extracted into, and this will be one of the most challenging technological components of space mining. Thankfully, testing these technologies can happen in Earth orbit before starting. Performing all mineral processing at the Main Belt has the added benefit of keeping the environmentally damaging waste product far from earth.
With regard to energy conservation, it should be noted that the Main Asteroid Belt is absolutely loaded with organic compounds, all of which are precursors of high energy compounds used in various rocket fuels. Even basic hydrogen gas can be synthesized from water. Just as extraction is carried out at the Main Belt, so too will fuel synthesis for the return journey. Also do not forget the contributions of solar power, nuclear power and later possibly fusion power to add their energy to the overall equation.

Myth #3: it is impossible to get significant weight back down to Earth from orbit.

Space processing and extraction are an area which will require new technologies to realize, and so too the approach to getting mass from orbit back to earth will require doing things in a new way. For the longest time humanity has thought from the perspective of lifting off from earth with great weight, but put less effort into getting back as only the weight of a human crew mattered. 

To beat this challenge, it seems that an old idea who’s time has finally come is the best approach: space elevators. Not a new idea, the principle depends on classic Newtonian physics. A long tethered line is attached to a weight in space, with the centripetal force pulling outward from earth, and the attached tether and gravitational pull of the Earth on the mass of the line pulling back towards Earth. The end result is a taut line which can lift and lower mass, which would greatly reduce costs of transportation. What makes this idea feasible today are advances in material science which now provide the strength of material required to maintain a space elevator, such as carbon and diamond fiber.

A space elevator may be impossible with current technology, but even other methods are possible, such as employing classic reentry capsule design, stripped down of crew and life support function with parachutes, could be economical enough to land high value minerals. One could target an exact spot for impact in a specially constructed location (perhaps even a lake), allow for a crash landing of the capsule loaded with precious mineral, then extract and refine said mineral from the impact site!
