Mission to Mars (2000) Poster

Goofs

Audio/visual unsynchronised 

When on the planet of Mars we continually hear sounds. There is only an insignificant atmosphere and so we wouldn't hear anything except for the radio in their helmet/rocket.

Continuity 

(at around 1h 16 mins) While viewing the DNA sequence on the computer, the cable on the left side is plugged in, and then out, and then in again.

(at around 1h 28 mins) When Jim checks pressure levels inside the face his readout says 6 psi, but immediately after they discuss pressure as being at 12 psi.

Crew or equipment visible 

Terri's visor allows light from the 'Big White Room' to become visible showing that it is not fully sealed. On the bottom right side the light is visible along with the curvature of her helmet, this is when they've entered the Martian Face and Jim begins to remove his glove checking for Earth PSI. Terri and Luke rush to his aid only to be proven right...it is from this point on that Terri's "GOOF" can be seen.

Errors in geography 

The dust storm shown on Mars would not have been dangerous to the mission and would not have required the action blown the astronauts so. The air pressure on Mars is a mere 6 millibars (compared to Earth's 1013 millibars), so the "fierce" duststorm would have had the impact of a feather on the people and space craft.
(at around 1h 30 mins) When the three astronauts enter the alien structure and view the solar system model, all the planets (and the Earth's moon) are revolving in the wrong direction. Viewed from the Northern hemisphere, planets rotate counter-clockwise around the Sun, and so does the Moon around the Earth. It is possible that the alien solar system model is seen from the other orientation i.e. our Southern hemispheres of the planets are on top for them. However a Mars with large ocean masses in the top hemisphere is seen, which is in fact our Northern hemisphere of Mars, assuming that water filled the depressions on Mars long ago.

Factual errors 

(at around 1h 18 mins) While looking at a DNA sequence Terri Fisher says that the last two chromosomes are missing. What is missing is actually the last two nucleotides of the sequence. DNA does not have chromosomes. Rather, chromosomes are comprised of DNA, and a single chromosome will contain many tens or hundreds of millions of nucleotides.
There is a fundamental misunderstanding of how the jet packs work. In space, with no friction or proximal gravitational pull, a single burst from the jets accelerates the operator into constant motion until a counteracting burst slows them down. There would be no need for the multiple instances of everybody "using up fuel" by burning their jets constantly when trying to maneuver.
(at around 1h 10 mins) Luke Graham was the sole survivor on Mars for many months. He attributes his oxygen supply to a room full of plants. A room full of plants could never release enough oxygen to sustain a human in an oxygen-free environment for one hour, let alone months.
Mars only has 38% of the gravity of earth yet it is clear from everyones' movements and walking that the gravity is identical or very close to earth's gravity.
The walls of the tent should be fully inflated by the much higher pressure inside, compared to the low atmospheric pressure of Mars.
(at around 28 mins) When Phil Ohlmyer shows the "DNA-model" of his dream woman to Jim McConnell, the free floating candy moves in a circular motion around the center of the model. Unless the candy is interconnected, this would be impossible to obtain in real life, as the individual pieces of candy can only have a straight line of motion. Even if you would rotate one candy in a circular motion and then release it, it would continue in a straight line tangent to the circle.
(at around 57 mins) The atmospheric pressure of Mars is less than 1% that of Earth and consists primarily of carbon dioxide, items falling from space would not burn up nearly as quickly in the Martian atmosphere as shown in the movie.

(at around 1h 28 mins) Inside the face, Jim checks the screen on his wrist to see what the gasses were in the room. It reads "Nitrogen 57% Oxygen 20% Trace Gasses 1%" which doesn't add up to 100%. The nitrogen should be at 79%.
(at around 57 mins) When Terri attempts to rescue Woody she resets her fuel readout to 100%, it is then stated that by using only 50% of her fuel the remaining 50% would get her back, This is incorrect. The first 50% would allow her to reach a certain velocity in respect to the ship, the remaining 50% would only allow her to get back to the same velocity as the ship not to the ship itself.
The Mars Recovery vehicle is shown pointing forward before it attempted to go into orbit. Any spacecraft would have to point backwards, and thus slowdown, to enter orbit.

The oxygen supplied to the engine would be just enough to cause the fuel in the engine to burn with little waste. There would not be excess oxygen to allow the leaked fuel to ignite and explode.

The Halon fire suppression system would have not existed on the spacecraft that went to Mars to rescue Luke. Production of Halon ceased in 1994 because it is a CFC (clorofluorocarbon), and any supply of recycled Halon would have long been exhausted before the mission took place (2020).

(at about 11 mins) The rover POV shows identified elements on screen, flashing them by quickly in green text. One of the entries reads "polonium aw 208." The 208 isotope is not naturally occurring. However, 210 has been detected in the Martian atmosphere.

Miscellaneous 

(at around 54 mins) When the crew have exited the ship after it exploding and Woody is flying towards the REMO, Phil looks at his wrist-mounted computer which tells him that Woody is going to overshoot the REMO. However, below the graphic on the right side of the screen, the caption contains a spelling error, reading: "Traget projection and outcome" instead of "Target.... etc."

Incorrectly regarded as goofs 

In the movie it stated that the 23 chromosomes came from mars about a million years ago and set off the explosive growth on the planet earth. Chromosomes are never mentioned in the dialogue. Merely that "they seeded earth" hundreds of millions of years ago. The only goof here is the time scale. Life is believed to have begun roughly 3.5 billion years ago during the Eoarchean period with true multi-celled organisms appearing during the early Proterozoic era, roughly 2 billion years ago.

Revealing mistakes 

(at around 32 mins) In the weightless scene inside the space station, Woody's watch slips down his arm, indicating the presence of gravity.

Spoilers

The goof items below may give away important plot points.

Crew or equipment visible 

(at around 1h 1 min) Shortly after Woody dies, a cameraman can be seen reflected in the face.

Errors in geography 

(at around 1h 45 mins) The galaxy that Jim is zooming off to in the final shot wouldn't look any different from Mars than it would from Earth. It would just look like a single star.

Factual errors 

(at around 60 mins) Space is not cold in the sense that exposure to space causes you to freeze instantly. There is nothing to conduct heat away from the body so the only way you can freeze in space is for heat to radiate away from you, and that is a slow process. Hence, when Woody removes his helmet, he'd die from hypoxia long before he freezes.

Plot holes 

There was no need for Woody to die by using up all his suit fuel to "aim to overshoot" the REMO. Woody only needed a quick initial burn to maneuver toward the REMO, letting the vacuum of space maintain his velocity without additional thrust. Then all Woody had to do was turn around and counter thrust at the REMO so Jim, Terri and Phil could join him and latch onto it.
