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 existence of ample amounts of hydrogen in the subsurface ocean of Enceladus indicates that microbes--if any exist there--could use it to obtain energy by mixing with carbon dioxide dissolved in water. This particular chemical reaction, termed methanogenesis, because it manufactures methane as a byproduct, may have been of critical importance in the emergence of life on our planet.
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.
So, the next time you're planning a big fishing trip, make sure you know when the moon sets and rises for that day and plan around it. You will find your fishing experience a much more rewarding one for having that bit of knowledge. I promise!
