Lunar Station

Bonwitt couldn't connect the moon's eccentric behavior with Peterson's. But something was up. If personal, okay; if against Atomic Power, something else again. Looking out first over the moon's broken desolate surface, then up at the bright orb of Earth, the engineer tried to rationalize things.

It couldn't be against Atomic. Mercury is something you just can't steal. It's heavy. Atomic is the only big market for it. You can't make big-time power on Earth without mercury, and Atomic has the monopoly. You have to have a fleet of space ships to transport it—and a market.
