In a recent study, NASA shared a vision that sounds like something out of a science fiction novel. Basically, the plan calls for the creation of robots that could be sent to a nearby asteroid, assemble itself, and then begin mining the asteroid itself. The scientists behind this study say that not only will this be possible within a few generations of robotics, but will also pay for itself – a major concern when it comes to space travel.
A couple of factors are pointing to this, according to the researchers. One, private industry is willing and able to get involved, as attested to by Golden Spike, SpaceX and Planetary Resources. Second, advances in technologies such as 3-D printing are making off-world work more feasible, which can be seen with plans to manufacture a Moon base and “sintering”.
But also, humanity’s surveys of space resources – namely those located in the asteroid belt – have revealed that the elements needed to make rubber, plastic and alloys needed for machinery are there in abundance. NASA proposes that a robotic flotilla could mine these nearby space rocks, process the goods, and then ship them back to Earth.
Best of all, the pods being sent out would save on weight (and hence costs) by procuring all the resources and constructing the robots there. 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. As the agency stated in their research report:
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…
