Samples from the asteroid Ryugu similar to Ivuna-type carbonaceous meteorites

Author Daniel Suarez speculates about how Ryugu could be mined in his novel Delta V[1].

Can visionary eccentric billionaire Nathan Joyce successfully mount a mining expedition to Ryugu? Maybe. (I've read only 75 percent of the book.)

The main plot line of Delta V concerns the mining crew's selection, training, and adventures in space. Of course, they must overcome many challenges. Most of the technology is purchased from subcontractors.

Joyce reminds me of D. D. Harriman, the titular robber barron in Robert Heinlein's novella, The Man Who Sold The Moon[2]. Both Joyce and Harriman manipulate financial and legal systems to achieve their dreams. Both must accept watching from Earth as their rockets fly to space.

It fascinates me that they heated a sample of Ryugu and drove off 15% of the mass as volatiles, particularly water and carbon dioxide. This is the stuff to make solar sails or a biosphere! Iron and silicon and aluminum are all well-represented, even phosphorous. I didn’t see much about nitrogen.
