Retired scientist David W. Jensen proposes a feasible plan to transform the #asteroid Atira into a rotating space habitat. The plan includes using self-replicating robots to build the #habitat and estimates a total cost of $4.1 billion and a construction timeline of 12 years. If successful, the project could provide 1 billion square meters of land in space.
