Armageddon Prep Package

An asteroid "the size of Texas" would be approximately 695,000 km² — comparable in scale to Ceres, a dwarf planet discovered in 1801 and visible with binoculars. An object that large and that close to Earth would be as bright as the stars of Orion's Belt and visible to the naked eye months, possibly years, before impact. NASA only watches 3% of the sky, but the claim that no one noticed a Texas-sized rock 18 days out is laughably impossible.

The opening scene shows the asteroid that killed the dinosaurs 65 million years ago striking near the Caribbean. The actual Chicxulub impactor struck the Yucatán Peninsula — visible in the same shot. Worse, 65 million years ago Earth's continents were in entirely different positions. North America, South America, and the Caribbean looked nothing like they do today. The filmmakers just used a modern globe.

The film states the asteroid that wiped out the dinosaurs released energy equivalent to "ten thousand nuclear weapons." The actual Chicxulub impact is estimated to have released more than a billion times the energy of the Hiroshima bomb — equivalent to over two million Tsar Bomba explosions, the most powerful weapon ever detonated. The film undersells it by a factor of roughly 200,000.

The film explains the incoming asteroid was knocked toward Earth by a comet passing through the asteroid belt. A single comet could not collide with enough asteroids to conveniently shove them all in the same general direction — and certainly not knock a Texas-sized object out of a stable orbit. The asteroid belt is also far more spread out and sparsely populated than the film implies.

The film states the asteroid "originated in the asteroid belt between Mars and Jupiter." The largest known object in the asteroid belt is the dwarf planet Ceres, which has a diameter of about 945 km (587 miles). Texas at its widest is about 1,270 km (790 miles). The asteroid in the film is literally larger than the biggest thing in the belt it supposedly came from.

University of Leicester postgraduates calculated that splitting an asteroid the size of Texas in half would require approximately 800 trillion terajoules of energy. The largest nuclear device ever detonated — the Tsar Bomba — released about 418,000 terajoules. The bomb in the film would need to be roughly two billion times more powerful than the biggest nuclear weapon ever built. That energy is also more than the Sun produces in an entire second.

The film treats the impact as survivable by half of humanity in a nuclear winter. An object the size of Texas striking Earth would vaporize the Pacific Ocean nearly instantly. The resulting plasma would sterilize the entire surface of the planet within roughly 30 seconds. There would be no nuclear winter because there would be no survivors — not underground, not on the ISS, not in the middle of the ocean. The comparison to the 65-million-year-old extinction is deeply misleading; that impactor was about 150 times smaller.

The plan is to split the asteroid so both halves miss Earth. But each half of a Texas-sized asteroid is still orders of magnitude larger than the Chicxulub impactor. Both halves would independently cause extinction-level events. The plan solves nothing.

In the opening sequence, as the dinosaur-killer asteroid flies past the Moon, the side of the Moon facing us is the near side — the side always facing Earth. Depending on the trajectory shown, the far side should be visible. A minor detail, but it's the kind of thing astronomers notice immediately.

When the military arrives at the rig to retrieve Harry, he has a large smear of oil on his nose visible in three consecutive shots. On the fourth shot it has completely vanished without explanation.

While A.J. works in a pit inside the Russian station, he is shown wearing a small knit hat. The following shot he has nothing on his head. The shot after that, the hat is back.

After the argument between Sharpe and Stamper, the countdown clock reads 5 hours 12 minutes. A few scenes later it reads 6 hours 49 minutes — time is going backward. The clock increases by over 90 minutes between shots.

The Paris meteor scene shows a POV from Notre Dame's walkway, with the Eiffel Tower and Hôtel des Invalides (Napoleon's Tomb) visible simultaneously. From Notre Dame's actual location, those two structures cannot appear in the relative positions shown. Notre Dame would need to be about a mile southwest of its real location for the shot to work.

During the scene where A.J. plays with cookies on Grace's stomach on their last night before the launch, a car visible in the background alternately appears, disappears, and moves around between shots.

When Harry goes to A.J.'s room and holds the golf club at A.J.'s throat, the tip of the club faces right in one shot and left in the next shot.

When A.J. bumps into Bear, his shirt is visibly dirty on the right side. As he runs up the stairs in the next shot, it is much cleaner and has a sweat mark around the neckline instead.

At the end of the film, Grace watches NASA controllers celebrating through the glass. The shot of the controllers is the same one used earlier when Grace looked worried at bad news — it was simply zoomed in slightly to try to hide the recycled footage, but one controller can still be seen cheering in the background of what should be a somber shot.

After the asteroid is destroyed, a large American flag draped in front of a building clearly shows a 49-star configuration rather than the correct 50-star layout. Hawaii became the 50th state in 1959. This flag has been wrong for nearly 40 years by the time the film was made.

Drilling 800 feet into the asteroid produces no visible cuttings removal. In all real drilling operations, cuttings must be actively removed — typically by circulating drilling fluid (mud) that carries debris to surface. On an asteroid with even minimal gravity, debris won't simply float away. No fluid system, cuttings return line, or debris removal mechanism is shown.

The drilling rigs shown are essentially standard onshore oil-field equipment including hoses, hydraulic systems, and conventional power sources. None of this is designed to operate in hard vacuum, extreme temperature swings from -273°C to +150°C, microgravity, or without atmospheric pressure for seal compression. Real asteroid drilling would require purpose-built, vacuum-compatible systems.

When cutting drill pipe in the hole, steel cutters are used. Standard drilling protocol in any situation with known gas pockets or gas residue mandates brass cutters — because brass doesn't spark on contact with steel, eliminating the risk of igniting residual gas. Using steel cutters in that scenario is a serious safety violation that no experienced driller would make.

During the rig opening, pipe flies into the air and oil shoots out dramatically. In a real blowout, drilling fluid (mud) comes out first — not oil. Blowout preventers (BOPs) would be activated hydraulically long before fluid reached that pressure. Pipe doesn't fly into the air unless every safety system was completely bypassed. A later shot shows a roughneck turning a single valve to shut in the well — in reality, BOP hydraulic rams are what contain a blowout.

It's established that NASA built the drilling rig from Harry's patents, but when it doesn't work they can't figure out why — even though it's grinding audibly enough that everyone in the room can hear the defective transmission. Harry lampshades this himself: NASA built the thing and can't diagnose an obvious mechanical problem.

Even if docking with a rotating station were possible, the centripetal forces required to simulate Earth gravity at short spoke lengths would apply enormous shear stress to the shuttle-to-station docking connection. The docking collar would almost certainly fail structurally under the rotational load.

Harry's roughnecks are trained as astronauts in approximately 12 days. NASA astronaut training takes a minimum of 24–30 months and covers orbital mechanics, EVA procedures, suit operations, rendezvous and docking, emergency systems, and zero-G adaptation. Ben Affleck noted the absurdity in the DVD commentary, saying he asked Bay why it was easier to train drillers as astronauts than astronauts as drillers, and was told to shut up.

The nuke is a military weapon. A random Mission Control technician punches a few keys and disables it remotely. Military nuclear weapons use PAL (Permissive Action Link) systems — multiple layers of physical and cryptographic authorization specifically designed to prevent unauthorized disarming. A civilian NASA keyboard operator would have zero access.

The shuttle's cargo bay doors are closed during the orbital satellite repair scene. Standard protocol required the bay doors open at all times in orbit — the doors contain radiator panels essential for thermal control. Closed doors would cause the shuttle to overheat rapidly. Additionally, the airlock is inside the cargo bay, meaning closed doors would trap the EVA crew outside.

The opening shows the shuttle bay doors open facing the void of space while astronauts work on the satellite far from the vehicle. During real satellite servicing, the shuttle is flipped so the cargo bay faces Earth (nose up, tail down), keeping the bay shielded from debris and in a stable thermal environment. The satellite is brought into the bay by the Canada Arm, not worked on at distance.

The shuttle crash-lands on the asteroid with significant visible structural damage. The Space Shuttle's thermal protection tiles were extraordinarily fragile — Columbia was destroyed when a single foam strike damaged one tile during launch. A crash landing that visibly dents the shuttle's structure would make atmospheric re-entry a death sentence.

The Colonel calls for "100% flaps" during landing. Flap positions are measured in degrees of deflection, not percentages. The Space Shuttle's maximum flap deflection was approximately 40–50 degrees. No real aircraft or spacecraft control system uses a percentage scale for control surface position.

Truman is shown in Florida talking with astronauts before launch, then appears to control the entire mission from the same Florida facility. In NASA operations, once a rocket "clears the tower," Mission Control in Houston (JSC) takes over from Launch Control at KSC in Florida. These are different buildings in different states. Truman would need to be in Houston for the mission phase.

The film states events begin on a Friday and the asteroid will hit in 18 days — which would be a Tuesday. The calculated impact accounting for all mission phases (1hr to MIR, 60hrs to moon, 12min slingshot, 8hrs on asteroid, 4hrs back after zero barrier) projects impact on a Friday evening around 8pm. The 18-day figure and the actual timeline are mutually inconsistent.

Colonel Sharp stops Harry from attacking the armed nuke with a large wrench, fearing he'll set it off. Nuclear weapons cannot be detonated by physical impact — they have elaborate safing systems precisely to prevent accidental detonation. A wrench strike on the casing would damage the bomb but would not cause a nuclear detonation.

The Russian station refuels the US shuttles with liquid oxygen. The Mir station and the Space Shuttle used entirely different fueling systems, connector standards, and propellant combinations. Mir had no reserves of shuttle-compatible propellants. The fueling sequence shown would require adapters, procedures, and supplies that simply did not exist.

The film implies US Space Command is based at the Pentagon. It was actually headquartered at Peterson Air Force Base in Colorado, co-located with NORAD — not at the Pentagon in Virginia.

The general who arrives at Harry's rig and identifies himself as commander of Pacific Air Forces (PACAF) wears two-star insignia. PACAF is a major command always commanded by a four-star general. A two-star would not hold that command.

When Oscar discusses Star Wars with A.J., A.J. measures something with a dial indicator held like a micrometer. A dial indicator must be mounted to a fixed reference surface to measure displacement of its contact arm. Holding it freehand like a micrometer makes the measurement completely meaningless.

The doctor describes Ketamine dramatically as essentially a horse tranquilizer. Ketamine is a widely-used human sedative and dissociative anaesthetic approved for human use since 1970 and used daily in emergency medicine — particularly for paediatric procedures like setting broken bones. It's a Schedule III controlled substance, not an exotic animal drug.

In a shot on the asteroid, a puff of smoke/steam reveals the shadow of a camera crane in the background. Visible production equipment in a film supposedly set on a distant asteroid.

When helicopters chase Oscar on his horse, a Wescam camera pod is clearly visible mounted on the lead helicopter — visible only in widescreen versions of the film.

When oil is struck on the rig and Harry scolds A.J. saying "Number 2 relief valve is wide open," Harry finishes speaking visibly on screen but his audio line ends before his mouth stops moving.

The crew boards the shuttles in sterile clean suits to prevent biological contamination. Yet Rockhound flicks a live, buzzing fly on the asteroid surface — reportedly visible in multiple other scenes on control panels inside the vehicles. This directly contradicts the sterilization protocols shown at boarding, and is additionally impossible in a vacuum.

After the shuttle crashes, wreckage is visibly on fire all over the asteroid surface. Fire requires oxygen. The asteroid has no atmosphere — it's a hard vacuum. Nothing would ignite, let alone sustain a flame. A vacuum wouldn't even produce a spark. This error repeats multiple times throughout the asteroid sequences.

After landing, steam is visibly rising from the ground. Steam is water vapour, which requires atmospheric pressure to form and persist as visible gas. On an airless asteroid in hard vacuum, any water-bearing material would instantly sublimate or flash-freeze with no visible effect. No steam plumes.

Throughout the film, rockets are heard firing, explosions are audible, and drill pipes clang loudly as they're tossed in a pile on the asteroid. Space is a vacuum — there is no medium for sound waves to travel through. None of this would be audible. The classic Hollywood space sound error, committed repeatedly.

The surviving shuttle takes off from the asteroid with a long horizontal runway roll. There is no air to provide aerodynamic lift on the wings. The main engines push backward, not upward. The maneuvering jets are far too weak to lift the shuttle's mass. A vertical rocket-style takeoff is the only option that makes physical sense in a vacuum.

Throughout the film the shuttles pitch, bank, and turn exactly like atmospheric aircraft. Aerodynamic control surfaces — wings, rudders, elevons — are completely useless in a vacuum. All attitude and directional control must come from thruster jets only. Spacecraft don't corner like racing cars.

Both shuttles launch simultaneously from pads shown close together. Kennedy Space Center's pads 39A and 39B are 8,700 feet apart — over 1.5 miles. Launching simultaneously from adjacent pads would be catastrophic: the combined exhaust, acoustic shockwaves, and thermal output would destroy both vehicles. The film also contradicts itself — the crew boards from a single tower, then appears at two separate launch pads.

Even ignoring pad distance, the acoustic and mechanical energy produced by a Space Shuttle main engine ignition is enormous. The neighbouring shuttle would be subjected to vibration levels that could cause catastrophic structural failure before it left the ground — on top of uncontrollable fire, steam, and debris from the first launch.

During the lunar slingshot, the crew is warned they will experience 9.5 Gs for 11 minutes. Untrained individuals G-LOC (lose consciousness) within seconds above 4-6 Gs without special suits and AGSM breathing technique. Above 9 Gs, even trained pilots with G-suits pass out almost immediately. The crew is shown screaming at each other — impossible, since you cannot forcefully exhale when 9.5 times your body weight is crushing your chest.

Truman tells the crew liquid oxygen is their fuel while refueling at the Russian station. Liquid oxygen (LOX) is the oxidizer — it enables the fuel to combust. The actual fuel is liquid hydrogen. Filling up with LOX and no liquid hydrogen is the rocket equivalent of putting water in your gas tank.

The space station spins to simulate gravity. At ~50-foot spoke length, Earth-equivalent gravity would need about 8 RPM — making docking essentially impossible. More fundamentally, centrifugal force in a rotating structure pushes outward along the spokes, away from the hub. Astronauts would be flung toward the ends of the spokes, not held to a floor. The film's gravity points straight down and works uniformly throughout the station, which is physically impossible.

Setting aside the direction of artificial gravity, physically docking a shuttle with a station rotating at 8 RPM would be extraordinarily dangerous — like trying to park a car on an ice-covered road into a spinning parking garage. The torsion forces on the docking tube alone would likely tear the connection apart almost immediately.

When the Russian space station ruptures, A.J. and Lev are shown running toward the shuttle through the hallway. A breach large enough to cause the visible destruction would create violent, instantaneous decompression. The outward rush of atmosphere would eject every person and unsecured object through the breach almost instantly. No one could run against that force.

When A.J. starts the Armadillo to jump the canyon, you hear large internal combustion engines roaring. ICE engines cannot function in a vacuum — they require atmospheric oxygen. The Armadillo would need electric motors, which are nearly silent. There's also no air to carry the sound anyway.

Both shuttles approach the Russian station with main engines burning. In space, once moving at orbital velocity you don't need continuous thrust to maintain speed. Main engines are for large velocity changes only. Using main engines in close proximity to a structure during rendezvous would be extraordinarily dangerous.

A.J.'s glove is visibly torn after the crash. A pressurized spacesuit breach would immediately begin venting atmosphere. The pressure differential would cause rapid, traumatic injury to the exposed hand — burst blood vessels, swelling, incapacitation within seconds. A.J.'s fingers look completely fine throughout.

Surface astronauts wear thruster suits to stay planted in minimal gravity. Yet the pilot walks normally inside and around the shuttle with no suit thrusters and no unusual effort. The same minimal gravity applies everywhere on and near the asteroid. She should be bouncing and floating like a Moon walker.

Rockhound fires a GAU-8/A Gatling Gun with ~10,000 lbf (45 kN) recoil per round. The vehicle doesn't move. On an asteroid with a fraction of Earth gravity, Newton's third law means the reaction force would rocket the vehicle backward rapidly. The barrels would also have been cold-soaked to near -273°C when pointed away from the Sun — firing at 6,000 RPM would cause the frozen barrels to shatter like glass rather than glow cherry red.

NASA cuts the communications uplink, which stops the nuke's countdown — implying it needs a constant signal to keep ticking. Modern nuclear weapons, once armed and triggered, count down and detonate autonomously. Cutting a comms link after arming has no effect on the detonation sequence.

The montage showing people around the world reacting to the crisis shows broad daylight on every continent simultaneously. Earth rotates — roughly half the planet is always in darkness at any given moment. This is not a subtle error; it's a basic property of how planets work.

When the Armadillo is spinning, thrusters are fired to stop the rotation. Firing thrusters incorrectly relative to the spin axis accelerates the spin or tumbles the vehicle. To arrest a spin, thrusters must fire in the exact opposing direction at the correct vector. As shown, it would make things much worse.

Rockhound flicks a live, buzzing fly on the asteroid surface. A fly cannot survive vacuum, extreme temperature, and radiation in space. The shuttles were supposedly sterilized before the mission. The same fly is reportedly visible in later scenes on control panels. This error is both a scientific impossibility and a continuity failure.

The film introduces "space dementia" as a syndrome Rockhound allegedly develops after roughly 30 hours in orbit. No such medical syndrome exists. Space travel can cause mild cognitive and psychological effects over time, but "space dementia" as an acute condition appearing in under two days is entirely fictional.

After the crash landing on the asteroid, crew members are shown with dirt on their faces — while wearing fully sealed spacesuits. There is no way for dirt or debris to get inside a sealed suit during impact. The dirt is purely a cosmetic movie decision to make them look more roughed-up.

Calculating from the stated size and composition (mostly iron), the asteroid's surface gravity is approximately 1.4 N/kg — slightly less than the Moon's 1.6 N/kg. The surface crew should be bouncing more dramatically than Apollo astronauts on the Moon with every step. Instead, they walk around as if they're at a normal 1G. The film does acknowledge the need for thruster suits, but the walking physics are entirely wrong.

NASA's fallback is to detonate the nuke on the surface if they can't drill. This is acknowledged in dialogue to be completely ineffective. The surface blast would not deflect or split an asteroid of this size — it would just be a very expensive firework on the surface. The film has characters explicitly point this out and then proceed anyway.
