- One rocket is fitted with about 50 compact, simple mining robots. Then about 6 bigger construction robots. And an unfoldable mass driver. Another rocket is fitted with a small portable LFTR and a plasma gasification unit, molds for simple, bulky robot and product parts (molds for wheel, chassis, mass drivers, and so on.) as well as about 150 or so circuit-boards for robots, as well as any lightweight components that are too intricate to create in orbit such as sensors, and some spare propellant. It sets off for some metal-rich asteroid.
- When it arrives, the LFTR is deployed, the construction robots set up the plasma gasification unit to connect to the LFTR, and mining robots go off to just pick away at rock. This rock is then carried back to the plasma gasification unit, where electricity from the LFTR is used to heat the temperature inside to about 14,000'C, which disassociates everything into its constituent elemental gases. These are then centrifuged and separated to be either in the collection tray to be launched as payload to Earth via mass driver, or to be poured in the molds for extra robot parts. Begin assembling more robots with the components you brought along. Any payloads you wish to send back to Earth get excess iron/nickel melted over it (as a makeshift heat shield) and some primitive thrusters to adjust approach into a designated impact site (Somewhere in a desert) where it can be collected and resold.
- If you want to mine the asteroid faster, just ship up another rocket with a thousand circuit-boards and sensors. It might be feasible to even launch small constructed LFTRs/PGUs and robots to other asteroids via mass drive to basically have a Von Neumann machine for mining the solar system.

Should specify that reproduction in MICROGRAVITY has problems, not space. Or do I have to ram an O'Neill cylinder up the authors arse?

I would say we could nudge an asteroid into a orbit only a couple of light seconds away from Earth which would allow Earth control centers to do such operations if they're required.

I don't know man, that was over a year and a half ago. But I do remember it was a bit more in depth than the others. At the time I vaguely remember seeing him from somewhere, it wasn't until a few weeks later that I googled him and was, 'Holy shit, I talked to a slightly famous science person!'

And last time I checked it said he was working at that university. On a secondary Google though I cannot find that information, so I don't know anymore.

Artificial gravity from rotating habitats is not a new idea, sorry.
