The creature’s body was so heavy that Thad had to return to the bridge, and shut off the current in the gravity plates along the keel, before he could move it.
An hour’s ascent, with our rocket-tails streaming like a comet behind us; then we shut them off, with the gravity plates set for Earth repulsion and the Moon to pull us on the first leg of the flight.
But there was nothing normal about a gravity plate that had resisted the tug of Mars only to buckle on little Phobos, crippling our ship on a blue moon that traveled in the wrong direction, and possessed a diameter of only eight minutes of arc when it was at its zenith.
