New this month Corrected entry: Matt Damon spends time philosophizing about the cross being the only flammable thing he can use. Yet anyone lighting a stove with an electric spark knows the better way to ignite a gas-oxygen mix is with a readily available electric spark. Presumably, they liked the drama of Damon blowing himself up, rather than pushing an igniter switch.
New this month Corrected entry: Matt Damon proposes using his suit air as an "Ironman" rocket to get across the gap. But any competent space person would recognize that in space, the best option is to simply jump. The two ships are motionless relative to each other. A small push, and he would coast towards the ship, in a straight line. Easily grabbed by the ship. Using an uncontrolled propellant was much more dramatic, but completely unwarranted. Earlier, Martinez was jumping around the ship, and showed the ease of aiming from point to point in space. Someone would have suggested jumping. They are in space, with no gravity, and no atmospheric resistance.
Corrected entry: When viewed from the front, the circular gravitational ring of the Hermes normally rotates clockwise. However just after retrieving the payload from the Taiyang Shen, it is rotating anti-clockwise. (01:32:15 - 01:33:30)
Corrected entry: When Mark had got his helmet glass cracked in the front, he had duct taped it but in the later scene he has a perfectly clear and undamaged helmet. He could not have got it from any other place as all the other astronauts had taken theirs on board the Hermes.
Corrected entry: Near the end when Matt is awake after launching the MAV, Commander Lewis mistakenly calls Mark Watley "Matt" when telling him the plans.
Corrected entry: When Mark is receiving the messages outside from Pathfinder, he uses a Sharpie or similar to write messages in his notebook. This is impossible, as in Mars' atmosphere and temperature, the ink should be boiled off or frozen.
Corrected entry: In several shots when Mark is grabbing the tether in space outside the Hermes, both of his palms are outstretched. He cut through one so he could use the air to propel himself towards Hermes, but air is not escaping from his hands.
Corrected entry: Johannson states that Mark Whatney's MAV was traveling at 741 m/s and his then altitude was 1350 meters. Then Commander Lewis states this is "too low." This must be too low, as at 741 m/s, he would have past 1350 meters in a little less than 2 seconds instead of the stated 12 minutes from launch to end of burn. This 1350 meters perhaps should have been 1350 km final altitude after the MAV finished its burn. (01:56:45)VistaDelLago
Corrected entry: After being rescued on Sol 561, Watney tells his crewmates he hasn't showered for "a year and a half." But the day he leaves the Hab, Sol 461, Watney steps out of what is the shower, naked and toweling off his wet body and hair. So it has only been 100 Sols since he last showered. Even in Earth time that's less than 4 months - nowhere near a year and a half.Aerinah
Corrected entry: After the Hab blows he gets in the rover, which should always be warm from the nuclear device. However it appears very cold and even shows his breath condensing.
