Profiting from the riches that asteroids, stars and even planets have to offer seems to be closer than ever, with two companies launching missions within three years. But experts say before going for the gold, platinum and diamonds that may be up there, they need to find the most precious of all: fuel.
Investors eager to get the new industry off the ground know this. That is why new ventures that have backing from some loaded business figures, and even the NASA, have decided to focus on building interplanetary “gas stations.”
“Have you ever wondered why the space economy hasn’t seen exponential growth with Moore’s Law like we have witnessed with high-tech industries here on Earth?” asks Planetary Resources President and Chief Engineer, Chris Lewicki.
“The catalyst for rapid expansion into every frontier in history has been access to cheap, local resources. And in space, access to rocket fuel is currently neither cheap, nor local,” he notes in a video (watch it below) about the market for fuel in space.
According to Lewicki, the business of mining asteroids for fuels could generate trillion-dollar market. In addition to platinum, the main asteroids in space mining companies target list are abundant in hydrogen and oxygen, which can be turned into propellants and sold to fill up the tanks of everything, from commercial satellites to NASA deep-space vehicles.
“This will literally and figuratively fuel expansion of the space economy by providing a locally sourced fuel resource that will change how industry operates in space,” says Lewicki.
Besides, says Lewicki, water harvested from asteroids can also be used as a radiation shield for humans during deep space expeditions to Mars, consumption and even aid in several processes tied to mining metals off asteroids.
NASA studies have previously found that fuel depots could reduce the price tag of deep-space exploration because spacecraft could take off from Earth with less fuel than they do today, which would allow the use of smaller, cheaper rockets. Filling an orbiting depot with propellants from asteroids could be far less expensive in the long run than supplying them from Earth, according to Planetary Resources cofounder Eric Anderson.
But the plan has its share of sceptics. “Technically, could they do it? I have no doubt,” says Henry Hertzfeld, a professor at George Washington University who studies space policy and economics. But he is not sure who the customers would be or what they would be willing to pay, and he says that the idea of mining on asteroids raises unresolved legal issues.
Ownership of space resources, he says, is a grey area in space law, with no clear allowance for private property rights on asteroids and other celestial bodies. “You can easily build a contrasting case where it makes no sense at all,” Hertzfeld says.

Not only fuel, but also drinking water, oxygen for life-support, naturally occurring stainless steel… the challenge is largely an engineering one at this point. While it is true that we currently lack a legal framework for the development of space resources, it didn’t stop the Europeans from settling the Americas… I have a feeling the lack of legal frameworks will not be such a hurdle.

So, it will be lawyers who decide whether we will be able to explore farther into space? In the colonoal days it was the drive for wealth and power that pushed exploration of the globe. If there was the lawers back then that we have now Christopher Columbus probablly would not have gotten a permit to sail to the Americas

An odd picture of big-tyred crawlers on the asteroid’s surface – if those things were there as pictured one bump would send them into orbit (for a 2 km radius asteroid a fast walking speed is orbital velocity) – with the low gravity existing on a space rock the crawlers would weigh 10 pounds or so (ie push down force) but with a mass of several tons – a real one would have to be wired down.

I totally agree with most of the logic but i wonder about the deep space support. At this time all of our deep space exploration is based on one off, large , complex, and fragile probes. To reach orbit and then dock at a fueling station to fuel tanks will require extraordinary measures to ensure the probe is not contaminated in any way that could foul cameras etc. Many issues for these probes will have to be addressed. I feel strongly about all other uses for the fuel and oxygen.

Keep on dreamin’!

The only real use for mass-extraction of water from asteroids is for manned expeditions. But the more water you add for shielding, the bigger the engines must be and the greater the fuel consumption. So the more water (hydrogen and oxygen) craft must carry. You can see where this is going. And how are you going to break down that water (for propellant use) without the energy density of sunlight needed, especially out beyond Mars?
The thing is hopeless.

re the crawler illustration: Yeah, hard to get away from how we expect things to behave. Like the moon landing deniers picking on the point that no lunar dust, disturbed by the rocket exhaust of the lander, appeared to settle on the top of the landing feet – duh! The dust was blown away at exhaust velocity 12,000 feet per second or so and would’ve landed miles away – if not an attempt at orbit.

The legal framework is a non-issue. Whoever mines it will own it…

Maybe Bruce Willis can help.

sure this will work, it won t be easy but it will work! 🙂

It’s a nice idea and all and the CEO’s statement that the fuels (hydrogen and water) manufactured are needed right now for geostationary satellites and our low earth orbit activities. I feel someone should break it to him that they use hypergolic fuels like hydrazine/nitric acid for thrusters and station keeping/maneuvering on these satellites not cryogenic fuels like hydrogen and oxygen that really are not suited to this purpose at all. Cryogenic fuels would be insanely problematic for his primary market as to make it all but impractical. How will he deal with fuel boil off if even every other obstacle can be dealt with without doubling the size of the satellite?

What is needed is support from industry and a commitment to do it without the government meddling which will doom those projects to failure.
Dreams can and sometimes do become reality in some cases.Civilization advance a step at a time. There is a place for dreamers but they need to have doers also to make it happen.
Love Your Planet
Stop wasting time money effort and brains on Space – get our Planet Earth back in good health first with controlled fish stocks, clean regular water supplies for all and a living, breathing atmosphere that we can all survive and thrive in. This talk of using more fossil fuels is just bananas. Wake up to the reality of what is going on around you on this Planet.

yes i agree with you completly.The real hurdle is the evil,money grabing non tax paying corporations!
