Ad Astra

Question: The Lima produces surges that disrupt electronics. Why isn't the Lima affected?

Question: How did the monkeys get onto the space ship and why were they so aggressive?

Answer: On the way from the Moon to Mars, the Cepheus interplanetary vessel receives an automated distress signal from a Norwegian bio-medical space station (that studies and conducts experiments on Earth animals in the deep-space environment). Apparently, a couple of very powerful and temperamental adult baboons escaped from their cages and killed everyone aboard the space station, feeding on their bodies. When the Cepheus answers the distress signal and arrives at the space station, the baboons attack and try to eat Captain Tanner and Roy McBride, also.

Question: Tommy Lee Jones killed his crew 16 years ago, but the corpses are still inside the ship, some of them without signs of decomposition! Is not it stinky living with rotten bodies? Why are they still on board?

Answer: He killed the crew by shutting down the life support. The vacuum would prevent them from decomposing. Since he was now a single person, he would not need to regain access to the entire ship.

But one corpse's head was deformed, presumably rotten, while the others were intact. Why is there a difference?

Answer: He also mentions that his last few loyal crew members recently attempted to return home. This is what damaged the reactor and caused the surges. It is likely that these are the crew Brad Pitt encounters.

Question: What was Roy's father doing for so many years? What did he plan to do next? Where did he get all the supplies of air, food, water, etc. to live in the space ship for so many years?


Answer: Clifford was continuing to gather data for the Lima project. He was convinced the project could succeed and that there was extraterrestrial life somewhere in the stars. He was apparently planning on gathering data for the rest of his life. Clifford would have plenty of supplies to last more than a lifetime, considering he murdered everyone else on the team.


Factual error: When driving across the moon, Brad Pitt waves his hand through lunar dust that's floating in the air. But there's no atmosphere on the moon to suspend dust like that, even if was kicked up by another buggy - it would fall straight back down.

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: Dust particles become charged by electrostatic and radiated by Ultraviolet rays from the sun. This would cause the dust particles would leap several centimeters above the surface of the moon and the lack of gravity would keep them floating there. This is why the moon has a 'Horizon Glow'. Source:

But these aren't "several centimetres" above the surface - they're a good metre or more up, at head height when sitting in the lunar rover.

There is no lack of gravity at that height. The particles would tend to fall back down to the surface like anything else would. They'd stay suspended at a constant altitude only if there's an upward force to balance the downward force. Even given that much, individual particles would not stay suspended stably owing to dynamics spelled out in Earnshaw's Theorem.

Roy McBride: The zero G and the extended duration of the journey is affecting me both physically and mentally. I am alone. Something I always believed I preferred. I am alone. But I confess it's wearing on me. I am alone. I am alone.

Trivia: When Roy McBride is reviewing a top-secret message regarding his father and the LIMA mission, the message filename is "6EQUJ5," which is a very obscure easter egg in the movie. The filename 6EQUJ5 refers to the real-life "WOW Signal," a deep space radio signal received by the Big Ear radio telescope at Ohio State University in 1977. The alpha-numeric designation "6EQUJ5" was a printed readout of the signal's duration and intensity. This signal lasted 72 seconds and was 20 times stronger than background radio noise, causing a surprised astronomer to circle the printed 6EQUJ5 readout in red ink and make the handwritten notation "WOW!" in the margin. While the signal was an anomalous one-time event that was never repeated, and there is still no proof that 6EQUJ5 was alien in origin, it has stimulated debate about extraterrestrial radio signals for decades. Ironically, the movie "Ad Astra" concludes that there are no alien radio signals and that we really are alone in the universe.
