Corrected entry: Near the end of the movie, Bowman instructs HAL to point his antenna towards the Earth - meaning he will not be able to relay his observations to the Leonov. The antenna moves, yet in the next shot of the Leonov crew, the Jupiter observation is still visible on the monitors.
Corrected entry: When Max and Curnow enter Discovery through the emergency airlock, they emerge inside the pod bay to find the last remaining pod (even though all three pods were actually gone). It is in the spot next to the airlock door, but later when Floyd, Curnow, Chandra and the other Russian cosmonaut are talking, the pod has suddenly moved two spots over.jbrbbt
Corrected entry: In "2001", when Bowman leaves the Discovery's cockpit, he descends a ladder that leads to the pod control room (on the ship's starboard side, next to the centered pod bay). But when the ethereal Bowman leaves the cockpit with Floyd following, tho Bowman heads toward starboard, they enter the pod bay through the port-side corridor. This seems to ignore Bowman's knowledge of the Discovery's layout. With time being critical, had Bowman wanted to 'teleport' himself and Floyd to the pod bay, he'd have done so directly - no walking at all. Intentionally taking a meandering route to the pod bay seems to go against Bowman's reason for being here. (01:23:15)johnrosa
Corrected entry: Dr. Chandra informs Dr. Floyd that HAL was "given full knowledge of the mission's true objective" and "was told to lie" to Bowman and Poole. Floyd protests, stating, "I didn't instruct anyone to tell HAL about the Monolith!", and when shown that the NSC gave the order, Floyd claims "I didn't know!" repeatedly, shocked. As Dr. Chandra never challenges Floyd on his defensiveness, he must believe Floyd, yet his investigation into HAL's orders surely would have come across the video message seen by Bowman after disabling HAL in "2001" wherein Floyd himself (played by another actor) states that HAL is the only one aboard that has been told the true purpose of the mission. Floyd must be lying and Chandra must know it, and with his deep affinity for HAL and desire to prove HAL innocent, he wouldn't let this lie go unchallenged. (01:14:10)johnrosa
Corrected entry: For aerobraking to work, the ship must enter the upper atmosphere of Jupiter. At no time does the ship come close enough to Jupiter to cause the friction needed to portray the flaming ball shown in the movie. (00:35:22)
Corrected entry: The alien intelligence behind the monoliths may be good at sending trite little messages of peace love and happiness, but they have just condemned the human race to extinction, along with every living thing on our planet. They change the solar system to a binary star system, which will inevitably alter the Earth's orbit. This will cause earthquakes that would make the planet uninhabitable, and the climate changes will finish off the few survivors. Turning Jupiter into a star capable of sustaining life will involve somewhow increasing its mass by approximately two hundred and fifty times. Jupiter simply isn't massive enough to become even a small, cold star (known as a brown dwarf) by itself. Using super-dense netron matter won't work: super dense matter is super heavy, that's the whole point. If you don't hugely increase Jupiter's mass it cannot become a sun.
Corrected entry: The Leonov crew launch a probe to make a close examination of the surface of Europa. As it gets close it shines a spotlight on the surface. The spot should be traveling at the same speed as the probe, meaning it ought to be traveling at several thousand miles per hour. Yet it's shown sweeping the surface so slowly that it can follow an animal swimming beneath the ice.
Corrected entry: In the prequel, 2001, there's a single room inside spaceship Discovery which holds an inventory of spare parts. In 2010, there are at least two such rooms, referred to as "Access Ways", which have huge numerals 1 & 2 painted on their walls.
Corrected entry: When Dr. Floyd is briefed on the chemical analysis of Europa, he acts positively astonished at the prospect of living things on that world. But why would this be a major surprise to him? The presence of extra-terrestrial life would be interesting to him, but not surprising, since he had already known of E.T.s years earlier when the TMA-1 had been discovered.
Corrected entry: While the probe is approaching the surface of Europa, Floyd is reading off the names of the chemicals detected. He says - 'Oxygen. Carbon. Chlorophyll. Is it organic?' Well, yes, chlorophyll would be organic - it's a huge, complex molecule which gives plants their green colour - and nobody of Floyd's intelligence and education would need to ask.
Corrected entry: Dr. Chandra asks the Sal 9000 computer to open up a new file. He types out the word 'Phoenix' as its name. Phoenix only has seven letters, yet nine keystrokes are heard. (00:14:50)
Corrected entry: When the Leonov arrives at Jupiter's moon, Io, it's found that spaceship Discovery, which has been passively orbiting Io for nine years, is heavily caked with powdery sulfur that's been spewed into space from the moon's many active volcanoes. But if the ship were plowing through that much sulfur on a regular basis, it's orbit would've decayed literally in a matter of months at the very most, and the ship would be a shattered mass of wreckage on the moon's surface.
Corrected entry: When Curnow does his EVA to the Discovery and lands on it he proceeds to the command module at one end where he feels full gravity, yet when he reaches for the hatch there's ½" of sulfur powder laying on the hatch (which shouldn't cling to the Discovery to begin with). When he brushes it aside it settles back on the Discovery instead of floating away. (00:49:20)
Corrected entry: In 2001, Poole takes a pod out to replace AE35. We see this pod spinning off into space. Bowman takes pod 2 out to retrieve Poole. He eventually blows the door to get back inside Discovery. There is no indication that he bothers retrieving this pod: He is occupied with HAL. Bowman takes pod 3 to check out Stargate. He and the pod are sucked in. So where did pod 4 come from in this film?
