In a few generations of robotics, we’ll see mighty machines able to fully construct themselves and operate from the surface of asteroids — providing applications for mining, NASA researchers say in a new study.
The scientists are convinced that this type of research is not only possible, but also able to support itself financially. (Costs overruns are a notorious factor in space exploration as it pushes frontiers both literally and engineering-wise.)
“Advances in robotics and additive manufacturing have become game-changing for the prospects of space industry. It has become feasible to bootstrap a self-sustaining, self-expanding industry at reasonably low cost,” the researchers stated in a new study.

A couple of factors are pointing to this, researchers said: private industry is willing and able to get involved. Advances in technologies such as 3-D printing are making off-world work more feasible. Also, humanity’s surveys of space resources has revealed the elements needed to make rubber, plastic and alloys needed for machinery.
NASA proposes a robotic flotilla could mine nearby space rocks. They caution the technology won’t be ready tomorrow, and more surveys will need to be done of nearby asteroids to figure out where to go next. There is, however, enough progress to see building blocks, the agency stated.
“Robots and machines would just make the metal and propellants for starters,” stated Phil Metzger, a senior research physicist at NASA’s Kennedy Space Center, who led the study.
“The first generation of robots makes the second generation of hardware, except the comparatively lightweight electronics and motors that have to be sent up from Earth. It doesn’t matter how much the large structures weigh because you didn’t have to launch it.”
A computer model in the study showed that in six generations of robotics, these machines will be able to construct themselves and operate without any need of materials from Earth.
At least two startups would agree with the optimism: Deep Space Industries and Planetary Resources.
In the past year, members of both firms have proposed asteroid mining ideas, and since then, Planetary Resources has also unveiled other projects such as a public space telescope (perhaps in a bid to diversify revenues and attract more attention.)
In early 2013, when NASA submitted its fiscal budget request for 2014, it also got in on the hubbub: the agency proposed robotically venturing out to an asteroid and bringing it back to Earth.
That’s received many questions from critics (including at least one government space committee), but NASA has argued it is feasible and a way to unite innovation across various sectors.
“Because asteroids are loaded with minerals that are rare on Earth, near-Earth asteroids and the asteroid belt could become the mining centers for remotely-operated excavators and processing machinery,” NASA stated.
“In the future, an industry could develop to send refined materials, rare metals and even free, clean energy to Earth from asteroids and other bodies.”

A side note, this isn’t the only NASA-funded group looking at asteroid mining. In September, NASA’s Innovative Advanced Concepts office offered Phase 1 funding to a Robotic Asteroid Prospector proposal.

robots are going to mine asteroids?, your insight is astonishing. Are you sure we shouldn’t send trained rodents or something more efficient than invincible metal machines virtually impervious to the harsh environment of space. We just need a few more years of ‘Exponential Growth’ due to the LoAR, we should have a robot iner in less than a decade on the drawing board, and believe me it’s not a matter of if we will mine asteroids, it’s what country and when in the next 25 years it’s going to happen. My guess is it will be an American Company who initiates the first step, which is then quickly surpassed by a Chinese program in 2028. I put my chips down beotch.
I was at a Star Trek convention in 1976, and there were people from NASA giving a talk on some of the long term projects that would become commercially profitable. The mining of asteroids for rare elements was one project that fascinated me even as a 13 year old.
I’m hopeful to see this happen on a large scale in my lifetime, and curious about the impact of price on the commodities market. Obviously, if one doubles the supply of a precious metal, the price is bound to be pushed down a bit.
