Title:Autonomous Restructuring of Asteroids into Rotating Space
Stations

    Abstract: Asteroid restructuring uses robotics, self replication,
    and mechanical automatons to autonomously restructure an asteroid
    into a large rotating space station. The restructuring process
    makes structures from asteroid oxide materials; uses productive
    self-replication to make replicators, helpers, and products; and
    creates a multiple floor station to support a large population.
    In an example simulation, it takes 12 years to autonomously
    restructure a large asteroid into the space station. This is
    accomplished with a single rocket launch. The single payload
    contains a base station, 4 robots (spiders), and a modest set of
    supplies. Our simulation creates 3000 spiders and over 23,500
    other pieces of equipment. Only the base station and spiders
    (replicators) have advanced microprocessors and algorithms. These
    represent 21st century technologies created and trans-ported from
    Earth. The equipment and tools are built using in-situ materials
    and represent 18th or 19th century technologies. The equipment
    and tools (helpers) have simple mechanical programs to perform
    repetitive tasks. The resulting example station would be a
    rotating framework almost 5 kilometers in diameter. Once
    completed, it could support a population of over 700,000 people.
    Many researchers identify the high launch costs, the harsh space
    environment, and the lack of gravity as the key obstacles
    hindering the development of space stations. The single probe
    addresses the high launch cost. The autonomous construction
    eliminates the harsh space environment for construction crews.
    The completed rotating station provides radiation protection and
    centripetal gravity for the first work crews and colonists.
