The Descent of Anansi

by Larry Niven

A space station manufactory attempts to become commercially independent from its government backers by exporting super-strong nanowire that can only be manufactured in free-fall.

Following an attempt to sabotage their first delivery and hijack the cargo, the intrepid crew realizes they can escape the hijackers. Their shuttle Anansi can become a modern-day version of its namesake, an African spider-god, by descending to Earth on a thread.

The physics of tidal forces are explained, and the possibilities of orbital tethers to accelerate payloads into higher orbits (or indeed de-orbit shuttles without retro-rockets) are woven into a hard science fiction thriller.
