The rest of the Palomino crew grows suspicious of the faceless drones’ human-like behavior: Booth sees a robot limping and Holland witnesses a robot funeral and discovers the Cygnus crew’s personal items in the ship’s living quarters. Old B. O. B. (“BiO-sanitation Battalion”), a battered early-model robot similar to V. I. N. CENT, explains that the faceless drones are in fact the human crew, who mutinied when Reinhardt refused to return to Earth and had been lobotomized and “reprogrammed” by Reinhardt to serve him. McCrae’s father had led the mutiny and was killed. Using telepathy, V. I. N. CENT tells Kate the truth about what happened. When Kate tells Durant, he removes the reflective faceplate from a “drone” to reveal the zombie-like face of a crew member. Appalled, Durant tries to flee the bridge with Kate, but Maximilian kills him. Reinhardt takes Kate prisoner, ordering his sentry robots to take her to the ship’s hospital bay to be lobotomized.
The astronomers then conducted an analysis called a Bouger correction in order to subtract the gravitational effect of topological features, such as valleys and mountains, from the total gravity field. What is then left is the gravity field hidden beneath the lunar surface, existing within its crust.
As of December 2015, confirmed liquid water in our own Solar System--excluding Earth--accounts for about 25 to 50 times the volume of our planet's water. The moons of our Sun's family thought to possess liquid water are:
The surface of our Moon's near-side is dominated by the bewildering and unique Procellarum region, and this area is characterized by numerous ancient volcanic plains, low elevations, and a strangely unique composition.
