There ’s gold in them thar ’ space rocks , say the mineworker of the future . There ’s also platinum , rare earth elements , and even water . minelaying in space may voice like science fiction , but as the founders of two space mining company recently told me , their plans are very real .
Meet the Miners
About 4 billion age ago , gravitational turmoil in the early Solar System bombarded the inner planets with asteroids . stargazer call this period the Late Heavy Bombardment . Early Earth was a roiling batch of lava , and as metal - fertile asteroids run into the molten aerofoil , they fall off inwards to the satellite ’s core . That ’s why Earth ’s core is made of iron , and why metal like Au , ash gray , and Pt are comparatively scarce in our planet ’s crust .
“ What we are mining on Earth really is mine the asteroids , ” explains Naveen Jain , founding father and executive chairman ofMoon Express . On Earth today , he says , “ the easy clobber has been mined , and now you have to keep on dig profoundly and deeply and deeper . ” Indeed , what we take aim to mine on asteroids is n’t so dissimilar from what we mine on Earth .
The asteroids still orbiting the Sun are made of the same materials as the ones that made up the Late Heavy Bombardment . Their highest engrossment is in the Asteroid Belt , a band that lies between the orbits Mars and Jupiter , but there are plenty of asteroids whose orbits bear them much closelipped to Earth . stargazer call them “ near - Earth objects , ” and Chris Lewicki , president and chief engineer ofPlanetary Resources , says they ’re the best topographic point to start space mining . Planetary Resources will quiz its Arkyd 3 prospecting satellite in area later this summer , and plans to start commercially mining asteroids by the early 2020s .

Moon Express founder Jain ’s fledgeling company , meanwhile , is the leading contestant for Google ’s Lunar XPrize , which aim to spur lunar exploration with a $ 30 million prize , and plans to send its first prospecting missionary work to the Moon next year .
There ’s a very round-eyed cause why the Moon is a target for Moon Express . It endured the same Late Heavy Bombardment as Earth , but it cooled and solidified more quickly — and it has no atmosphere to burn up meteorites on entry . Jain say this means that metals are just wait to be piece up on the lunar Earth’s surface .
“ All of the asteroidal material is go to the Moon , and is being shatter and is lying on the airfoil , so in some sense , what you ’re doing is literally collecting this stuff right on from the airfoil of the Moon that you want , ” he explained to Gizmodo .
And in the absence of a lunar atmosphere , the Moon ’s open does n’t get eat away by wind and water , so the mark of ancient impact craters stay fresh — offering ready entree to deeper deposits of mineral .
Where Will They Go First?
The society that may one day mine these resources have very different ideas about where to stake their claims .
Jain and Moon Express , for representative , say the Moon is a logical situation for development , because it contains material from billions of years deserving of asteroid impacts , all in one berth . “ Why would you require to go to an single asteroid when Moon has been aggregate the asteroids for 4 billion years ? ” he said .
Moon Express has already built and tested a lunar lander able of bring and taking off again , which it demonstrated ina tether test flight sooner this year . That earned the company $ 1 million from Google for being the first – and so far , the only – ompany to pass on that milestone in the Lunar XPrize contention . To win the full swag , Moon Express will have to land on the Moon , travel 500 metre across its control surface , and place home high - definition video recording of the trip .
But Planetary Resources says that it sees asteroid as easier mark than the Moon . “ Many of these asteroid are actually easier to get to with esteem to rocket power than land on the airfoil of our own moonshine , ” contends Lewicki . “ bring on the Moon is an extraordinarily unmanageable affair , and occur back is even harder , but with the asteroids , because of their lack of gravity , and because there ’s so many of them , it ’s an easier place to get started . ”
Of naturally , it may not really matter where the first distance miner stake their claim in the long ladder , because others wo n’t be far behind with their eyes on other sites . Lewicki state Gizmodo , “ Just as world have presence all over the world , whether it ’s the South Pole or the other 6 continents and research bases , I calculate forward to humans having presence at all the interesting seat in the Solar System , whether it ’s the Moon , Mars , or hollowed - out asteroid . ”

When They’re Getting There
Jain says that Moon Express plan to launch its lunar mission next year . “ Our first mission is primarily a prospecting mission , then we ’re going to start bring this material back in our 2d and third missions , ” he said .
Along with the lander , that first missionary station will gestate a minuscule telescope called ILO - X , establish by Moon Express for the International Lunar Observatory Association . ILO - X will be accessible online to students , teachers , researchers , and members of the populace . “ Anybody will be able to go onto the net , and they will be capable to control the telescope , take a image and download it , ” enunciate Jain .
Moon Express is also working on an remote-controlled bird , which it say could carry experimental materials back from ISS , or loads of minerals back from the Moon . Like NASA ’s former Space Shuttle programme , the Moon Express drone shuttlecock is design to make a relatively smooth landing place when it recall to Earth – but unlike the old Space Shuttle , the Moon Express vehicle will be sovereign . “ You weightlift the button , and it comes glide down through the re - incoming [ with ] a heat buckler , and it open up the chute , and it uses its own Global Positioning System to land within a ten - time truth , ” explained Jain . The first shuttlecock is on the ISS manifest for a 2016 mission , he told Gizmodo .

Meanwhile , Planetary Resources has an early version of its Arkyd prospect planet aboard ISS right now . Arkyd 3 is a image to verify that all the planet ’s basic systems will make . The company plans to try more advanced features on its next role model , Arkyd 6 , including an infrared sensor for detecting water – the first cloth the company want to harvest – and a precision pointing system which will be crucial for laser communications . That mission is schedule for launch next year .
“ We see being able to extract a commercially useable amount of water is really in the early 2020s , ” said Lewicki . That will start out with using telescope on Earth to narrow down a list of asteroids that probably contain water . “ But for be sure , we actually have to post out a machinelike space vehicle and make mensuration quite close to the asteroid to be able to narrate with enough confidence to begin the next stage of exploration . ” That , of course , is where the Arkyd satellites occur in .
Lewicki says Planetary Resources plans to start by bringing back smaller quantities of piddle to screen in the lab , but finally , the company expects its water - mining business to develop alongside the space manufacture . “ As the technology matures , and of path , as people can start to matter on this piss sourced from infinite , the two will kind of develop in parallel , starting with fueling satellites in Earth Orbit that are in reality already up there today , and go to building out new thing that are beyond anything we ’ve done in history so far , ” he say .
Rare Earth Elements and Precious Metals
Space excavation companies are , of course , affirmative about what they ’ll ascertain .
Many beholder are concerned in space as a quick reservoir of what are yell rare earth element – seventeen metal elements which are crucial to the electronics industry but not often notice in large enough deposits for excavation . At the moment , 97 % of the world ’s uncommon earth element come from mine in China , which is a security measures business for the U.S. and its allies , and an economic concern for many consumer electronics companies . Space excavation , if successful , could split China ’s near monopoly on uncommon earthly concern elements , reduce the cost of many consumer electronics , and alleviate the impact of uncommon ground mining on Earth ’s environment .

But how unwashed are they in space ? “ As you’re able to think , they are called uncommon Earth elements , they are not bid rarified Moon element , ” said Jain , and there do seem to be surface deposits of rare ground element on the Moon , according to satellite observation . However , it ’s not yet clean how abundant they are , since uncommon earth ingredient are still hard to detect with remote instruments , and the Apollo mission only visited about 5 % of the lunar aerofoil .
The presence of precious alloy like platinum and atomic number 79 in space is better realize . In metallic asteroid , Lewicki told Gizmodo , “ It ’s really still just a very small amount of the asteroid , certainly less than a hundredth of a pct , but it ’s a very worthful and very useful hundredth of a per centum . ”
And base on the fragment that have made it to Earth ’s surface as meteorite , some asteroid may have much denser tightness of these alloy than we ’ve found so far in the Earth ’s cheekiness . It ’s likely that the Moon ’s has at least the same abundance of atomic number 78 - group alloy as on Earth , and it ’s probable that it has at least some deposits with the same immersion as metallic asteroid .
Of naturally , “ abundant ” is a comparative full term . alloy like the atomic number 78 - chemical group metals and rarified land elements are n’t really vernacular anywhere in the universe . They ’re produce only by the death throe of massive stars , after all .

As with rarified world constituent , fetch back precious metal from space could frown costs , but Jain is n’t disturbed . “ You have intercourse , people say , ‘ if you could bring a gazillion tons of platinum , do n’t you see the price of the platinum coming down ? ’ And I say , ‘ Do you realize , if I do bring the gazillion tons of platinum , I ’ll be way too rich to figure out whether it would be down or up ? ’ ” Jain told Gizmodo . But he contribute that he sees minelaying rare earth elements and precious metallic element as a short - terminus project . In the longsighted running , he ’s much interested in other possibleness .
So are Lewicki and Planetary Resources .
First Target: Water and Orbital Fuel Stations
Despite the glint appeal of bring home expensive metals like amber , platinum , or rarified worldly concern elements , the entrepreneurs who be after to actually make the first mine in distance get more frantic about something that seems terrene by comparison : body of water .

“ water system really is the exciting thing that is break to open up up our ability to search and develop space , ” said Lewicki . Space foreign mission take body of water , and mickle of it . Crews need it for drinking and hygiene , and deep space missions could apply urine for radiation shielding . And of class , it can be broken down into H and oxygen for rocket fuel .
Today , blank space mission have to bring everything they ’ll require from Earth – solid food , piss , and enough fuel to reach a destination or defend an orbit . Rocket launches are expensive , and just how expensive they are bet on how much mass is being launch . allot to Lewicki , “ Shipping one long ton of water into space today costs more than $ 60 million , and each man in space really direct several tons per twelvemonth , even with recycling , to support their activeness in space . ”
But if military mission could take on tonic body of water supplies , or refuel , in orbit , whether the water comes from the Moon or a near - Earth asteroid , they could found less material from Earth , bring through costs , and potentially stay in space longer or journey further , according to ship’s company like Moon Express and Planetary Resources .
“ They can refuel themselves mightily in Earth orbit or in the Moon ’s orbit going forward . In some sense that would deoxidise the monetary value of the rockets because you do n’t have to carry all the fuel , ” said Jain . “ Just like when you go from California to New York , you do n’t run all the fuel , you refuel yourself on the way . ”
Lewicki said , “ Just like we have gas stations and resource where we want to use them all across the United States and elsewhere in the populace , we ’ll develop that same substructure in space , and we ’ll practice the resource in space to avail do that . ”
Monetizing the Moon
harmonize to Jain , relatively average moon rocks themselves could be deserving the tripper . “ Just bringing the Moon rock itself to Earth , I think , as a novelty point can be just an amazing good business , ” he articulate .
mention : NASA
presently , NASA possess the only moon rocks ever carried home on a spaceship , but other man of the Moon have found their way to Earth over the last few million years . When large asteroids stuck the Moon , the impacts blasted chunks of the lunar surface out into space , and some of them struck a nearby innocent bystander – globe . These rock , call lunar meteorite , are worth a circumstances .
concord to Jain , “ I have in mind , gold is about $ 50 a Hans C. J. Gram . These lunar meteorite sell for anywhere between $ 1,000 to $ 10,000 a gram , so they are more like 20 time to 200 times pricier than gold , just the meteorite . And if you ’re able to bring the material Moon rocks , I mistrust , in the market place , even a small quantity of Moon rocks would be deserving a billion dollar sign . ”
Building in Space
Although returning precious metals to Earth is potential to be profitable , both companies seem to see blank excavation as a way to build substructure for outer space exploration in the foresighted run . For object lesson , water could leave fuel for vehicles and support human crews and possibly even plans . And metals from asteroids and the Moon could be the anchor of orbit habitat or stuff for microgravity spacecraft factories .
“ In the tenacious terminus , you want to really keep the Moon resources and use them in situ ; that intend using the resources on the Moon for , essentially , live on on the Moon , or create some type of a stepping stone for cryptical quad geographic expedition , ” said Jain . “ What we ’re looking at is , in the long terminal figure or medium term , you desire to be capable to create a home ground on the Moon , and whether it ’s using the lava thermionic vacuum tube or whether we are using , essentially , some eccentric of biosphere , as long as we have piddle there , and we have a keen soil , you should be able-bodied to essentially use a 3D printing process lab decent there , right on on the Moon itself , to be able to create the habitat that we need . ”
Lewicki also picture using three-D printing process on a big scale , using materials that Planetary Resources hopes to mine from near - Earth asteroid , and he told Gizmodo that Planetary Resources is currently researching the engineering with a company called 3D Systems .
“ There ’s a lot of metal in an asteroid , just round-eyed branding iron and nickel and cobalt , things that are actually useful for construct blank structures , ” he say .
Today ’s spacecraft , from satellites to rich space probe , are built on Earth , and that means they ’re work up with a rocket launch in mind . “ We in reality have to build it to hold out a very thought-provoking and very hard roquette launch , and have to fit it into the shroud on top of the skyrocket , and oftentimes , like with the Mars wanderer or other things , we have to do all sorts of complicated things to shut down it up and make it fit in the small-scale space . ” By build spacecraft in orbit , using metals mine from a nearby asteroid , railroad engineer could avoid those constraint .
Regulations and Claim-Jumping
For Jain , the prospect of big - musical scale human presence in space raises interesting questions . “ If you generate income from Moon , all on the Moon , is it taxable or is it not taxable ? I ultimately reason out the government will always take their piece of the Proto-Indo European , ” he state Gizmodo .
And it ’s not at all absolved yet how Earth ’s governments would address import taxes on materials land to the satellite from blank space , although Lewicki said that those regulations would plausibly develop along with the diligence . “ Just how we track ship coming in and out of port , we ’ll develop this manufacture in space as well , ” he said . There ’s some precedent already – when the crew of Apollo 11 returned from the Moon , one of their first check was a usage checkpoint in Hawaii .
Other aspects of regularise the space mining manufacture are starting to fare together . Earlier this month , the U.S. House of Representativespassed the SPACE Act , which articulate , among other matter , “ Any asteroid resources obtain in outer distance are the property of the entity that obtain such resource , which shall be gentle to all prop right thereto , coherent with applicable provisions of Federal natural law . ” The “ applicable provisions of Union jurisprudence ” line could pave the way for tax income clear in blank or materials brought down from orbit .
And claim - jump may be just as illegal in distance as it was in the Old West . The 1967 Outer Space Treaty provide for a 125 - mile “ non - interference ” zone around any crew spacecraft , for base hit purposes . It ’s not yet clear whether that would apply to excavation operation on the open of a body like the Moon . But Jain go optimistic about the possibility ; he tell Gizmodo , “ That , to me , is commence to get middling close to the right hand of I am here , and it ’s mine . ”
Of of course , the non - interference zona would n’t enforce , necessarily , to unmanned operations , which means that independent minelaying operations , like those project by Planetary Resources , might not be cover , at least by that treaty . That remains to be find out .
