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.
Titan's atmosphere is approximately 95% nitrogen. However, in a way that dramatically differs from Earth's own mostly-nitrogen atmosphere, Titan's atmosphere has very little oxygen. Indeed, the remainder of Titan's atmosphere is almost entirely composed of methane--along with small qunatities of other gases, such as ethane. At the extremely cold temperatures that are found at Saturn's great distance from the heat of our Star, Titan's methane and ethane can accumulate on its icy surface to form pools of liquid.
"The rectangular pattern of gravity anomalies was completely unexpected. Using the gradients in the gravity data to reveal the rectangular pattern of anomalies, we can now clearly and completely see structures that were only hinted at by surface observations," Dr. Jeffrey Andrews-Hanna explained in the October 1, 2014 NASA Press Release. Dr. Andrews-Hanna, a GRAIL co-investigator at the Colorado School of Mines in Golden, Colorado, is lead author of the paper.
The discovery of a moon for Makemake may have solved one perplexing puzzle concerning this distant, icy object. Earlier infrared studies of the dwarf planet showed that while Makemake's surface is almost entirely frozen and bright, some areas seem to be warmer than other areas. Astronomers had suggested that this discrepancy may be the result of our Sun warming certain dark patches on Makemake's surface. However, unless Makemake is in a special orientation, these mysterious dark patches should cause the ice dwarf's brightness to vary substantially as it rotates. But this amount of variability has not been observed.
