(at around 1h 16 mins) While Luke Graham and the others are viewing the signal's waveform, their POV of the display shows different devices in a different environment from shot to shot, made up to look similar.; the cable with the D-Sub connector is half plugged in in one shot and fully in another. The device is slightly different in details, the stuff on the bench in the background and even the color timing of the two shots is different.

(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.

(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.

The walls of the tent should be fully inflated by the much higher pressure inside, compared to the low atmospheric pressure of Mars.

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.

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 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. Correction - space vehicles do not need to turn around to decelerate. Engineers design them so such a maneuver can be accomplished without losing your forward view by adding rockets to the front of the craft. There are 6 on the space shuttle.

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.

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

(at around 54 mins) When the crew exits the ship after it exploded 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."

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).

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.

Why would a greatly advanced and supposedly benevolent race as the Martians incorporate such a deadly response to any incorrect inquiry to their face monument or make it such a puzzle to understand? They obviously had anticipated contact from their Earth progeny so would have made the Face more "user friendly" and less dangerous.

If a surface mission was speaking to an orbiting station, it would not take 20mins to send it. It would be near instant real time so, there would not be a 20 min outcome.
