A city on an asteroid, The idea is incredible today and will likely be for hundreds of years, maybe even forever. But it did not work to invent a way to crystallize it. And even less if, as the authors of the formula assure, it can be implemented with technologies that already exist or are in the development phase.
That’s exactly what a team of researchers did University of Rochester, in the United States. offer? A flexible mesh bag made of high-strength, ultralight carbon nanofiber to wrap around the giant rock.
This is key, they explain in their study published in the journal Frontiers in Astronomy and Space Scienceto solve numerous obstacles Which would render an urban project unimaginable in that way.
Being made of debris left over from the formation of the Solar System 4.6 billion years ago, asteroids are not strong enough to withstand gravity and twirl.
Thanks to this net, it would be possible to envelop the asteroid and contain all the rotating mass of its debris, supporting its own weight while it continues to spin. They point out that this would provide the perfect balance, as it would allow the whole body to be held together and at the same time be extremely light.
This would facilitate the construction of potential cities, for which the authors take a model devised in 1972 by physicist Gerard O’Neill, After consulting with NASA to design a customized habitat that would allow humans to live in space, the scientist conceived the so-called ‘O’Neill Cylinder’, composite rotating space metropolis by two cylinders in opposite directions, with a rod between them. The system would operate fast enough to provide artificial gravity for its inhabitants, while allowing life inside.
