Factual error: The atmosphere pressure of Mars is 0.07 Bar, Earth is 1 Bar, about 14 times greater. Yet the plastic covering of the greenhouse is shown flapping with the outside breeze. With the inside of the greenhouse having an Earth-like environment its plastic covering would have been inflated like a balloon against the weaker Mars atmosphere.

Mistakes
The spacewalk is replete with violations of physical laws: [1] Thruster exhaust would be necessary only to start and stop motion: not to sustain motion. 'Fuel' would be used only to start and stop motion. Thus, once Terry started towards Woody, she would not be in danger of running out of fuel during the trek. She would only need fuel to stop once she reached him. (Of course, she would need more fuel to start & stop the return trek. But even more fundamentally: Woody would not have expended his fuel load during his transit so Terry wouldn't have needed to come rescue him in the first place.) [2] When the grappling hook was launched, the person holding the launching device would be propelled in the opposite direction as the grappling hook's direction. (The larger the mass, the slower the acceleration, but thruster fuel would still be required to counteract the forces derived from the hook's launch.) [3] When the grappling hook stopped due to its line being fully extended, the line's tension would cause the bodies at both its ends (the hook & the gun with the gun's possessor) to snap towards each other. As erroneously depicted, only the hook end recoiled. See more...

Factual error: Their complete and utter disregard for the most basic scientific facts in this movie is amazing. It's already been said that Gary Sinise couldn't possibly have recognised the DNA sequence as human (that segment may have been enough to produce a single protein common to any lifeform). The thing that gets me is that he recognises that the DNA is missing a couple of "chromosomes" to complete it. DNA is made of units called nucleotides (remember A,T,C,& G?); chromosomes are formed by huge strings of DNA wound together (not the other way around). You don't need a degree in Biology to know this, you just need to have stayed awake in high school.
Continuity: The computer terminal used by Don Cheadle's character has a grey cable connected but the connector appears damaged - twisted out of alignment. A few seconds later the same cable appears connected normally then, a few seconds after that, it is damaged again.
